Wine Clarification -- Isinglass

IsinglassIsinglass is a super pure form of gelatin which is made from fish bladders. Isinglass is a very quick acting fining agent which is most effective on white wines. Is is very poor as to lees compactness as it creates a heavy deposit (see December 8, 2007 blog article regarding lees compactness).

The Isinglass sold by BlueStem Winery is in liquid form and is in a 45mL packet. At the recommended rate of 1mL/L this packet would be adequate to treat two 6-gallon carboys. Isinglass is also marketed in a powdered version.

After fermentation is done, mix liquid Isinglass with a small portion of wine and then stir this mixture into your carboy. Allow wine to clear for two or more weeks and then rack to a clean carboy.
