Acidex Super-K is a brand new, simple-to-use tartaric acid reduction powder. It works by neutralizing, accelerating the formation, and precipitation of naturally occurring tartaric acid crystals, a.k.a. ''wine diamonds'' present in high acid wines. Acidex Super-K contains Potassium Bicarbonate and Potassium Bitartrate and is used after fermentation and does not alter the structure of the wine. It does however, slightly raise potassium levels and increases the pH of the wine to between 3.2-3.6. Available in two sizes, #6122A, 3 oz. and #6122B, 1 lb.. Both packages are labeled with complete directions, including usage amounts. Wine must be stabilized and fined before use. An acid test kit is always recommended. Please note that Acidex Super-K should not be confused with regular Acidex, a complicated to use Calcium Carbonate based reduction powder that is used to treat high tartaric and high malic acid wine before fermentation.
DIRECTIONS: Wine must be stabilized & fined first. Add 1.2g/L directly to high acid/low pH wine (wine should be >1.0 TA /<3.0 pH). Stir vigorously for 1 minute. Reduces TA by .1g/L. CAUTION: DO NOT add more than 3 oz (83g) total to 6 US gallons (23L) of wine. Cold stabilize for 2 weeks before racking off of the tartrate precipitate. To reduce TA greater than .3g/L, use Calcium Carbonate USP.
