Be aware that a lot Tartaric Acid available to home winemakers is artificially made, comes from China, and does not integrate into the wine as well. Some of this tartaric includes the designation of "food-grade". Because MoreWine! packages this product you can be assured you are getting the highest winery-grade quality. 3.8g per gallon adjusts acidity by +.1%. As a note: some tartaric acid will drop out of suspension as potassium bitartrate if you are doing any cold stabilization. You might want to re-test total acidity after cold stabilization.

Used primarily in sanitizing solutions to lower pH, therefore making the SO2 solution more effective. Use 1 tbsp per gallon along with 1 tbsp meta per gallon. Citric is not added directly to must prior to either primary or ml fermentation as its metabolism can lead to volatile acidity. A rough approximate of weight is 1 tsp = 4 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.  Domestically produced in the USA.

Due to high demand, the 55 lb is currently out of stock. Be the first to receive your items by placing a pre-order today. We will automatically ship this to you when we receive more inventory. 3.4g per gallon adjusts acidity by +.1%. It will lower pH less than will tartaric acid. Malic acid is the acid found in apples and is therefore the best choice for adjusting ciders.  Malic is less sour than tartaric acid and can also be used to make acid adjustments in Rieslings, Gewurztraminer, and Muscat varieties, though many winemakers still prefer to use tartaric acid in these situations. You would not want to add Malic acid to any wine that will undergo a malolactic fermentation. As a note: only half of the artificially added malic acid will convert to lactic acid during a malolactic fermentation. A rough approximate of weight is 1 tsp = 2.7 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.

Ascorbic acid is a quick-acting and powerful antioxidant that is used in white winemaking to protect against light and short aerations, such as racking and bottling. It works by rapidly converting dissolved oxygen into hydrogen peroxide before it has a chance to react with oxidative enzymes and cause browning. However, this hydrogen peroxide itself needs to be removed from the wine in order to avoid the very phenomenon that was trying to be avoided in the first place, namely oxidizing the wine. The answer lies in always making sure that the free SO2 levels are correct, both before the ascorbic addition is to be made and after. (Note that "Titrettes" are not accurate enough for this, and that a more precise means of determing free SO2 is needed, such as an Aeration-Oxidation set-up). Addition rate is around 50 mg/l (ppm) as long as the free SO2 is maintained at 30 mg/l (ppm). A rough approximate of weight is 1 tsp = 3.2 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.
