Each sachet treats up to 23 liters or 5 gallons
MA33 is especially valued as an acid reducing yeast strain. It has the ability to metabolize approximately 30 to 35 percent of malic acid, which can help:
Reduce sharp or aggressive acidity
Create a smoother, more balanced palate
Improve drinkability in fruit wines, blush wines and lighter white styles
This makes it a strong choice for recipes where fresh fruit character is important, but acidity needs to be softened for a more rounded finish.
The yeast is well suited for:
Fruity white wines
Blush wines
Country wines made from a variety of fruits
Recipes where acid balance is a key part of the final profile
Each sachet also contains all thirteen essential trace vitamins and minerals, helping support healthy fermentation and consistent yeast performance. This built in nutrient support can be especially helpful for home winemakers working with musts that may vary in natural nutrient content.
