Possible Reasons For Your Wine Not Finishing

I know! For all my avid readers out there (both of you), it has been just a few days since I have posted. I had three tractor trailers deliver merchandise to BlueStem Winery including a truck just chock full of Cellar Craft wine kits and another from my Ohio wholesaler loaded with winemaking equipment, brewing supplies and WinExpert wine kits. I have pretty much put everything on hold for a few days as I try to unpack, check merchandise and re-stock shelves. Oh, yes, the third truck. Actually, Cellar Craft got one of my pallets on the wrong truck and it went to Texas instead of to Iowa. The store in Texas just kept the pallet and a new pallet of Cellar Craft kits arrived a few days later from Ontario to replace the wayward one.

A question was received from one of my customers who lives in San Antonio, Texas. San Antonio is one of my favorite cities, mostly because it was the only duty station I had other than my year at DaNang, South Viet Nam during my four years in the Air Force. If I remember right, downtown was a mass of one way streets which all met in the center of town. One giant traffic jam! The other thing I remember is gun racks in the back window of every pickup truck. Most likely loaded!

Anyway, my question was as to why my customer's wine was not finishing. When making wine, the wine is usually fermented down to a specific gravity of 1.000 or slightly less and then it is transferred from the primary fermenter (usually a plastic bucket) to the secondary fermenter (usually a 6-gallon glass carboy). The wine then finishes in the carboy down to a specific gravity of 0.992 to 0.994. My customer's wine would ferment down to the 1.000 mark and it (the wine) would be transferred to the carboy where it would ferment down to 0.996 to 0.998 and then stop. It would not finish. He wanted to know why.

There are several reasons why one of our Cellar Craft or WinExpert kits might not finish.

The first (or most common) reason is temperature. My customer, however, was maintaining a temperature of 75 degrees F. where the wine was being fermented and this is warm enough. The temperature was being maintained, too. Fluctuations in ambient temperature (as little as 5 degrees F.) can put wine yeast into shock and poor performance (a stuck fermentation) can result. We do not believe either of these to be the cause.

The variety of yeast being used can also be a factor. There are numerous types of wine yeast available and each has its own fermentation character. I know that Cellar Craft typically uses Champagne yeast because it is very forgiving and is very neutral. Champagne yeast can also tolerate wider temperature ranges, high alcohol levels (excessive amounts of alcohol present can also cause a yeast to stop fermenting) and produces smaller amounts of unwanted by-products.

Timing is also important. It is important that home winemaking enthusiasts rack (move their wine from primary to secondary) at the right time. Different wines have different points at which the movement is more advantageous but in this case the target was a specific gravity of 1.000 or less. Try to make this move as close as possible to 1.000 (not over but under 1.000). Above 1.000 can result in excessive foaming. Too far below 1.000 can result in a stuck fermentation right at the end of fermentation. This is very much a possibility for my customer!

Besides racking the wine at the most optimum time as described above, another thing that can be done is to not be too careful when racking the wine. In other words, do not try to totally avoid racking all of the sediment present in your primary fermenter into the secondary fermenter. Let some of this sludge (sediment) siphon over into your carboy. This small amount of sediment will help provide nutrients for the yeast during this final fermentation stage.

Decanting Wine (or Aeration vs. Oxidation)

A quiet spring Sunday at BlueStem Winery. April is always a quiet month as people start to get yard work done after a long winter. We received a large shipment of Cellar Craft wine kits last week and we have more Cellar Craft ingredient kits coming in on Tuesday. Our new supply of WinExpert kits along with a resupply of wine making supplies, homebrew equipment and home brewing ingredients will arrive tomorrow.

Yesterday's blog visited the importance of using a good cork when making wine. Today we are going to talk about removing the cork and enjoying the wine.

So, you have made 30 bottles of either WinExpert or Cellar Craft wine from a kit and you bottled it and you have waited the appropriate time and it is now ready to enjoy. I don't like to generalize but my rule of thumb on white wines made from either WinExpert or Cellar Craft kits is that you should wait a minimum of six months after bottling to enjoy the first bottle and a year is better. On red wines made from either Cellar Craft or WinExpert wine kits you should generally wait a minimum of a year and two is better.

But, as I said, you have waited the appropriate amount of time and it is time to enjoy. You have been told that oxygen is the enemy of wine and during the wine making you diligently tried to isolate your wine from oxygen as much as possible. Now it is time to drink your first bottle and I am going to tell you that prior to drinking your wine you should mix oxygen with it.

Yesterday we talked about corks and how a poor cork could lead to the oxidizing of your wine. There is a difference between oxygenation and aeration. Oxidized wine is wine which has been allowed to come in contact with oxygen during its storage life. Oxygen has attacked the wine and ruined its flavor and this wine can no longer be enjoyed.

Aeration is the mixing of oxygen with wine just prior to enjoyment. Wines which have been in storage will develop a smell which does not mean spoilage, it just means that we are unaccustomed to this aroma because we are used to smelling food which has been in contact with air, not isolated from it. Wines which have been in long-term storage may have chunks of sediment in them and will also have this slightly foul aroma. Use a special wine funnel which has a screen in it to do two things. Filter out the chunks and mix oxygen with your wine. This aeration will, in a few minutes, remove the unpleasant aroma. Will it damage your wine? No! Oxidation takes a little time, maybe hours and maybe a day. Open your wine, aerate it and enjoy!

As always, BlueStem Winery not only carries the winemaking supplies you need for your home wine making hobby but we also carry a complete line of home brew supplies for our home brewers. Our website is open all day every day or if in the area please feel free to drop in even if just to say hello!

The Importance of a Good Cork

It is a good day to write a little bit about the importance of a good cork when bottling wine. It is a Saturday, the store is open but not yet busy, and on Monday I will be getting in a shipment that includes WinExpert wine kits, winemaking equipment and home brew supplies. On Tuesday I am expecting in the second shipment of Cellar Craft wine kits in the last week. These two shipments might must keep me too busy to write blog articles so best get it done today.

I know there are many home wine making people out there and you use a number of different kinds, styles, lengths, and diameters of corks when you bottle one of your Cellar Craft or WinExpert kits or some of your backyard fruit wine. When people are in the store my criteria for helping them select corks initially centers on what type of corker they own or wish to purchase. If they own (or want to purchase) a plastic hand corker (or what I call the brute force method of putting a cork in a bottle) I recommend either the #7 or #8 diameter corks. The #7 corks are the smallest diameter corks and are also the lowest quality. The #8 corks are a medium diameter cork and are of marginally better quality. Why do I recommend these two corks if they are of lower quality? Mostly based on the corker itself. The #9 corks are the largest diameter corks but are virtually impossible to insert into a bottle using this corker. The #7 and #8 corks also have chamfered ends which assist in insertion. We do sell one style of #9 cork with chamfered ends but these are of the same grade as the #8s.

The next choice in corkers is to purchase either a Portuguese or Italian double lever corker. They operate on the same principle (tapered sleeve for the cork to slide through prior to insertion) as the plastic hand corker but instead of pounding on the top of the corker with your hand or a rubber mallet, you pull two levers apart which in turn drives a plunger downward which pushes to cork through the tapered sleeve and into the bottle. Do they work well? No! I personally like the plastic hand corker better. Do they work with a #9 cork? Maybe if you are Hercules!

If your hobby is important enough to you to own a floor corker then the choice of corks comes down to style and quality as opposed to diameter. A floor corker will insert a #9 cork into the bottle easily. Pick the quality cork that you need based on the length of time your wine will be in the bottle. Cork choices range from first quality corks (these are the same grade as the #8s) to winery grade twin disc which are an agglomerated (compressed ground up cork) cork with a disc of natural cork on each end to Altec corks which are agglomerated suberin (this is the highest quality cork available) to synthetic corks. I personally use either the twin disc corks or the Altec corks for bottling our wine here at the winery.

So what is the importance of a good cork?

The whole purpose of the cork is to establish closure. Closure to me is defined as the ability to seal the bottle so that air does not transmit from outside the bottle to inside the bottle. Please do not believe anyone who tells you that a cork breathes! This would imply that air passes through the cork and this simply is not true! Air can pass by the cork if your cork is of a smaller diameter or if it is damaged in some way or if your corking process puts a crease down the side of the cork. If corks did breathe then I would not be in the business of making wine. I would be in the business of making a liquid that had a taste similar to vinegar!

If wine does aerate because of a poor quality cork or a leaking cork the wine will oxidize and in turn it will lose the protection of the free SO2 (sulphites) and then the tannins, pigment and polyphenolic protections of the wine will leave followed by the loss of flavor and discoloration of the wine.

My advice is to purchase the very best corker that you can and then purchase the very best corks to put in your wine bottles. Lots of cork shoved into a very small space makes for longer lasting wine.

Not to forget our beer brewing customers, BlueStem Winery carries a complete line of homebrewing supplies, homebrew ingredients, and home brew equipment in addition to our fine line of WinExpert and Cellar Craft kits and other home winemaking supplies. Our beer brewing supplies inventory has grown significantly and we look forward to serving either your home brew or wine making hobby!

Number 2 On The Shelf!

BlueStem Winery started marketing the second of our wines just a couple of days ago. It was a long time between Number 1 and Number 2. Our first wine (Once in a Blue Moon) was out for sale in May 2007. It took us all the way to March 2008 for our second wine (Red Crescent) to be put out for sale. However, things will be happening rapidly over the next few months as our third wine (Dark Side) will be on the shelves most likely by May 15 with four more wines scheduled to be available during the summer months.

Once in a Blue Moon is a Canadian Riesling dessert wine. Red Crescent is a Cabernet Franc dessert wine with the grapes coming from Washington state. Dark Side is a Montepulciano wine whose grapes were grown in the Andes in Chile. Our other wines (as yet unnamed) coming this summer will be a Gewurztraminer, a Riesling, a Gruner Veltliner and a Gewurztraminer dessert wine.

King George has done his best to screw up the American economy but whatever is happening seems to have helped BlueStem Winery. Our sales on the internet and our store sales were both up about 35% over last year. We have been running an inventory reduction sale on both our WinExpert and Cellar Craft wine ingredient kits and these have been moving out the door rapidly in anticipation of our restocking in late April. Out with the old and in with the new!

Home brew supplies sales have been brisk . . . probably our largest increase in traffic for the month. I think the downturn in the economy has people looking at saving a little money by making wine and purchasing beer brewing equipment to cut back on the cost of their indulgences.

Home winemaking using WinExpert wine kits or Cellar Craft ingredient kits almost always results in some very, very good wine if the wines are allowed to age just a little bit prior to enjoying them.

One of my favorite stories here at the winery involves a couple from Cedar Falls, Iowa who were in the store several years ago. They purchased a WinExpert Selection Original Gewurztraminer kit and I told them that when the kit was finished that they should put it in the basement and forget that they owned it. Two weeks after the wine was bottled Barb e-mailed me and told me that the wine was not very good. I reminded her that she should put the wine away and forget about it. I told her that she needed to wait at least six months. Well, in six months I got another e-mail from Barb saying the wine was good and getting better every bottle. They later came in and purchased a Liebfraumilch and even later a Riesling wine kit. Barb's husband was in the store one day at a point in time where the Gewurztraminer was now 15 months old. I asked him how the Gewurz was doing and he replied that they "had one big problem". It seems that they were down to only ten bottles remaining and it was the best they had ever had in their lives.

So, if you want great wine, get on the BlueStem Winery website and purchase a wine making equipment kit and maybe one of our WinExpert wine ingredient kits or one of our Cellar Craft wine kits or maybe round up some backyard fruit and some winemaking ingredients and get a batch started. A six gallon batch will yield 30 bottles of wine and with a little patience you will be rewarded with some great sipping pleasure.

No patience? Then how about some home brewing equipment and homebrew supplies (also available on the BlueStem Winery website). It only takes about five weeks from start to enjoyment when brewing your own beer.

Hops are a little expensive right now but you only use a couple of ounces per batch and the other brewing supplies you need are relatively inexpensive.

About $30 will purchase beer brewing supplies for a 5-gallon batch. Wine making ingredients are very inexpensive if using backyard fruit and the WinExpert kits and Cellar Craft kits are available in the $80 to $150 range and will net you 30 bottles of wine per kit. Both the winemaking equipment and homebrew equipment kits are approximately $100 (or more if you want all the bells and whistles).

So, if you need a way to forget that the economy is a shambles, that gas prices are rocketing toward $4 a gallon or that your grocery bill is going out of site, then we can help. Relax and have a home brew (or some home made wine!).

Wine Making for the Future

My son and I disagree on a lot of things! We get along, we just disagree. We agree to disagree. The only thing we really argue about is politics and I can live with that. I don't know where he went astray. My first clue should have been when he voted for Bush. My personal opinion is that King George II will go down in history as the worst president . . . period! Whenever I mention his name in a sentence the word moron is usually also in that sentence. Just what has this administration done right? Really!

Anyway, the other day my son begins talking with me about one of the few things we really like to visit about. Wine! The other thing we talk a lot about is our Ford Mustang drag cars (a whole nuther story!). Nick (my son) has been purchasing wines as investments. He reads about these wines in Wine Spectator. He purchases these wines with the intent of keeping them for a few years and then reselling them. One of his most recent purchases was a 2005 Robert Mondavi Cabernet Sauvignon Reserve. So, he comes to me with the idea of BlueStem Winery making a reserve wine. Since Cabernet Sauvignon is his wine of choice he also suggested that this Reserve wine by a Cabernet Sauvignon blend.

So, we are now looking for all things wine making for our Cabernet Sauvignon Reserve. We have found a source for the juice we need and we will have a little bit of winemaking equipment in addition to what we have. Then it will be just a matter of working our way through the process of fermenting, oak aging and bottle storage for about 3 years. We will probably limit production to about 20 cases per year with the first wines being ready for sale in 2011.

We are being pleasantly surprised this month. We the economy seemingly in turmoil (thank you, King George!) we have been expecting a downturn in sales for our wine making ingredients and home brew equipment store. Instead, we have had our best March ever and still have over a week to go in the month.

We had sold more of our Cellar Craft and WinExpert wine kits in the first nine days of the month than we had in any full month since we opened our store. Store traffic has been brisk and I have been extremely pleased with the volume of homebrewing ingredients being sold in the store. Our stock of both WinExpert kits and Cellar Craft wine kits is getting very low as we try to sell out our inventory prior to restocking in April (when the ice is gone and the ground has firmed up enough to get our forklift out to unload a truck). If any of our store or on-line customers are reading this tidbit, thanks for your business! We are looking forward to having another 9 months of great business serving you in 2008.

The Fascinating Business of Wine Making

A fellow blogger left a comment on one of my previous blog posts today about how she had always been intrigued with the winery business. I guess I was intrigued with this business at one time, too. 80 hour weeks making wine and running a retail store selling brewing supplies and winemaking supplies can sure make it unintriguing (apparently that is not a word, my blog's spell checker just hiccuped!).

In my prior life I was a combat flier in the Viet Nam, taught high school and was a commercial banker. The flying was exciting (and slightly dangerous), the teaching was interesting (maybe even more dangerous), the banking was tedious (and the hours were long) and the wine making is a fascinating way to make a living (but the hours are very, very, very long).

Mondays are spent packaging beer brewing supplies, winemaking supplies, and WinExpert and Cellar Craft wine kits which were sold on via the internet over the weekend. Any time left over is spent checking our in process wine, and restocking our retail store shelves with winemaking equipment and home brew supplies. Restocking can be a time consuming process as many of the wine making ingredients must be weighed, labeled and packaged. If we have sold some of our BlueStems Best home brewing ingredients kits then replacement kits must be packaged and put out for display. This can take a great deal of time as the grains must be milled, weighed and packaged and the hops must be weighed and packaged, too. The shelves for our Cellar Craft and WinExpert ingredient kits need to be restocked, too.

Tuesdays are spent doing more of the same with less packaging and more of the other things. If we are going to start fermenting a new batch of wine we will start this when my wife gets off from her high school teaching job. It usually takes about four hours to get a 150 gallon batch of wine in the fermenters. Evenings are also when we will typically rack wine from one tank to another tank to get it off its sediment.

From Wednesday through Saturday we are open from 11 to 5 so I spend my time in the store. I spend time between customers vacuuming (isn't that intriguing!), restocking shelves and heaven forbid, dusting! Early mornings are spent packaging the website sales of homebrewing equipment and home winemaking supplies plus any WinExpert wine kits or Cellar Craft kits sold overnight. Evenings are sometimes spent racking wine or filtering wine or adding needed additives to wine in the secondary fermenters.

Sundays we are open from Noon until 4 and we actually have a little shorter day at the store. Unless we are going to bottle wine! If we have wine to bottle we usually have one person watch the store while we get the crew (myself, my wife, my son and his wife, my daughter-in-law's parents and anyone else we can corner) together to bottle wine. It takes the crew about six hours to bottle and cork 1,600 bottles of wine.

The fascinating business of making wine! Between the homebrewing ingredients and homebrew equipment and the Cellar Craft wine ingredient kits and the other wine making supplies we find the time to put together tanks of wine, rack the wine from tank to tank, filter the wine, and bottle it. If my calculations are right, our average week is 70 hours or so. Banking? Hell no! Teaching? Maybe. Climbing back into an EC-47 and flying over northern South Viet Nam, Laos and Cambodia? Absolutely (especially if we can just go do the flying and leave out the shooting part!). Making wine? Intriguing, fascinating, and even though it is week after week of very long hours, it is the best job I have ever had. I especially like the not having a boss part of doing this job!

Acid Reduction in Wine through Malolactic Fermentation

Malolactic fermentation is an effective way to reduce both malic acid and citric acid levels in wine. This article will not discuss the procedure for conducting a malolactic fermentation (a subject for a leter blog article) but will only provide background information.

A malolactic fermentation reduces total acidity (TA) in wine and when conducted, its goal is to reduce the harsher malic acid concentrations into lactic acid which is a much softer acid.

It is virtually impossible for home wine making enthusiasts to determine the levels of malic acid present in their wine. The only method of determining the effect on the wine is to take a TA measurement prior to conducting the malolactic fermentation and then take another reading post fermentation. The difference between the initial reading and the final reading is the amount of TA reduction which has occurred. If acid levels have been reduced too far it can be increased by the addition of acids or by blending with higher acid wines. If the acid level has still not been reduced to the desired range, then other acid reduction methods including blending, the use of potassium bicarbonate, dilution with water or cold stabilization can be used to further reduce acid levels.

BlueStem Winery is a full service retail and web source for winemaking supplies, wine making equipment and ingredients for making wine. BlueStem Winery also carries a large inventory of WinExpert wine kits and Cellar Craft kits for the wine making hobbyist who enjoys making their favorite varietals from around the world.

Wine Number 2 Gets Label Approval

BlueStem Winery's second wine will be available for retail sale very, very soon. Our label application to the federal government for this wine named Red Crescent was approved today and we should be able to have the artwork on the way to our printer early next week.

Red Crescent is a dessert wine made from Cabernet Franc grapes raised in the Yakima Valley of Washington state. A very smooth after dinner sipping wine with a fairly solid punch to it! We are hoping that this wine will be on our shelves for sale by mid-March 2008 followed shortly thereafter by our third wine which is a dry red which will be named Dark Side.

BlueStem Winery is a licensed and bonded Iowa winery. Our business consists of the winery plus a retail and web outlet which features winemaking supplies, homebrewing supplies, wine making ingredients, brewing ingredients, home brew and wine making equipment and WinExpert and Cellar Craft wine kits.

Wine making is our livelihood but we also enjoy a good home brew on occasion. Our store and website feature our own line of beer brewing ingredients kits known as BlueStems Best where you can choose from approximtely 30 different beer styles with pre-measured ingredients provided in the kit.

If you are into home winemaking we will always recommend one of our Cellar Craft or WinExpert wine kits and you will not be disappointed. World class! For all of your home brewing supplies and supplies for making wine, look to BlueStem Winery.

Acid Reducing Solutions for Wine Making

Both potassium bicarbonate and calcium carbonate solutions can be used to reduce acid levels in finished wine. The preferred of these two is the potassium solution because the calcium carbonate solution results in an unpleasant taste to the wine.

When adding either of these solutions to wine, the wine maker should realize that the first acid that the solution will lower is the preferred acid, tartaric. The wine maker must take care that the tartaric acid present is not eliminated completely from the wine.

Reduction in acid levels in finished wine are accomplished at about a 1:2 ratio. Total acidity is reduced by 1g/L for every 2g/L of bicarbonate that is added to the wine. Dissolve the bicarbonate in a small quantity of wine and then add the solution to your wine. If your initial acidity reading indicates that you need to reduce the total acidity by 2g/L, do not make a solution totaling 4g/L (remember the 1:2 ratio) and add it to your wine all in one swoop. Instead, make small incremental additions of the solution and taste and take additional acidity measurements in between each further addition of solution.

BlueStem Winery operates a retail store in Parkersburg, Iowa selling winemaking equipment plus ingredients and supplies for home winemaking. BlueStem also carries a large inventory of both WinExpert and Cellar Craft wine kits to enhance your home wine making experience.

Acid Reduction by Blending

When you are attempting to increase (or decrease) the acidity of wine by blending two wines together, the first step is to determine the titratable acidity (TA) of both wines. The second step in this process is to determine the volume required of the blend wine which will be required to raise (or lower) the TA of the wine you are trying to alter.

The formula for determining the volume of blend wine required is:

Z = X * (DTA - W) / (Y - DTA) where

DTA = Desired Total Acidity
W = TA goal of wine to be modified
X = Volume of wine to be modified
Y = TA of blend wine
Z = Volume of blend wine

Example: If you had 6 gallons of wine (X) with an existing TA of 6.2 and you desired to raise the TA of this wine to 6.5 (DTA) by blending an unknown volume of wine (Z) which has a TA of 7 (Y) your formula would look like this:

Z = 6 * (6.5 - 6.2) / (7 - 6.5) or

Z = (6 * .3) / .5 or

Z = 1.8 / .5 or

Z = 3.6 gallons of blend wine with a TA of 7 will be required to increase the TA of our 6 gallon batch of wine with an existing TA of 6.2 to our desired TA of 6.5.

Increasing Total Titratable Acidity in Wine

One method of increasing total titratable acidity in wine is with the addition of acids in the form of either tartaric acid or with the addition of what is called an acid blend. The preferred additive is tartaric acid, especially if the vintner is planning for the wine to undergo a malolactic fermentation. Acid blend is a mixture of tartaric, malic and citric acids. Many acid blends sold through home wine making shops is a 10-40-50 blend of tartaric, malic and citric acids. The acid blend that BlueStem Winery sells (mixed here at our store) is a 50-40-10 blend. Instead of the heavy concentration of citric acid that is in most shops (citric is cheap), BlueStem's acid blend is heavy on tartaric acids. Heavy concentrations of citric acid tend to give your wine a sharp, citric acid bite (similar to tasting a grapefruit).

BlueStem Winery urges caution in the use of acid blends (especially those prepared with large concentrations of citric acid). Acid blend should never be used with wines planned to undergo a malolactic fermentation.

Making wine at home with one of the WinExpert or Cellar Craft wine kits from BlueStem Winery? Then you won't have to worry about total acidity. Both Cellar Craft and WinExpert kits are acid balanced and will be perfectly balanced when you make them.

Acid Reduction in Wine

Four different acids can be typically found in wines during fermentation. These include tartaric, citric, malic and lactic. Acids in too high quantity have an adverse affect on the taste (and quality) of wine. Whereas increasing the acid levels in wine is a relatively easy process, reducing acid levels in wine can be difficult.

Over the next few days a discussion will be held about procedures for reducing or increasing the various acid levels.

A summary of these articles is as follows:

Addition of tartaric acid will result in an increase of the tartaric acid levels (that one was pretty obvious!);

Addition of acid blend will increase the levels of tartaric, malic and citric acid;

The blending of other wines with the wine in question can either increase or decrease the levels of tartaric, malic, citric or lactic acids;

The addition of potassium (or calcium) bicarbonate will decrease the level of tartaric acids;

Causing the onset of a malolactic fermentation will decrease the tartaric and malic acid levels while increase the lactic acid level;

Cold stabilization will decrease the level of tartaric acids;

Use of products known as ACIDEX or SHADEX will reduce the levels of tartaric and malic acids; and

The addition of water will decrease the levels of tartaric, citric, malic and lactic acids.

BlueStem Winery is a purveyor of wine ingredient kits from both WinExpert and Cellar Craft. These kits allow you to make excellent wines with never a worry about tartaric, malic, citric or lactic acids as the kits are acid balanced to assure you a perfect wine every time. Making wine could not be easier and the results are world class. WinExpert wine kits have been part of BlueStem's inventory for almost four years and our customers have expressed nothing but satisfaction with these fine kits. We added Cellar Craft wine kits about eight months ago and the reports coming back from customers have been nothing but fantastic!

BlueStem also has a full array of winemaking equipment, wine making supplies, homebrewing ingredients, homebrew supplies and brewing equipment.

Today was a fun day at the store with two couples getting started with their new wine making hobby and another couple purchasing beer brewing supplies to start their new hobby. I always tell my new customers that home wine making is the greatest procrastinator's hobby that there is. Other than the first week when you have to stay pretty close to the schedule it is a hobby that you can attend to with quite a bit of variance in timing.

Need home brewing supplies? A good Cellar Craft wine ingredient kit? Our website features one low cost shipping fee per order. We would very much like to ship a new hobby to you and are more than willing to support you with answers to your questions after you get started.
