Yeast Nutrition

For yeast to start the fermentation process and for it to continue the process through to a full fermentation it needs an environment rich in nutrients. If your must lacks proper nutrition you may have wine that does not begin fermentation or that becomes stuck (stops fermenting) or which develops a rotten egg smell (hydrogen sulfide develops which is caused by a shortage of nitrogen).

Nutrients which wine must requires include nitrogen (nitrogen produces protein which is required for the development of new yeast cells), oxygen (without getting too scientific, oxygen helps the initial yeast cells procreate rapidly) and trace vitamins and minerals (these include phosphorus, urea, citric acid, and amino acids among others).

BlueStem Winery markets it own line of beer brewing kits (known as BlueStems Best), home brew equipment, wine kits from both WinExpert and Cellar Craft for wine making at home, and home brew supplies from Muntons, Briess, Brewmart and others. Cellar Craft wines from their Showcase Collection produce world class wines as do wines from our selection of WinExpert wine kits. If you are looking at getting started in either the home winemaking or home brewing hobby, BlueStem Winery has the home brew supplies, homebrew equipment and winemaking ingredients you need for these great hobbies.
