Can help for stuck ferments
I have used this a couple of times on stuck ferments that get stuck due to high acidity levels (usually when doing fruit wines with acidic fruit). After adjusting temperature and stirring to re-suspend yeast, adding additional yeast and nutrient, I finally figured out that my must was too acidic. I added some potassium bicarb, and fermentation was rolling again soon. If your must has gotten too acidic, you may need to add fresh yeast after adjusting ph.

Hard Cider makers also need this
I use it to adjust my pH upward a little when my base is too acidic.

Protects the yeast from too much acidity
I use a pH meter to check on the acidity and make sure the yeast aren't under stress. This is most common with cider and fruit wine making with RO water that has no buffering ability.

Can it be used as treatment for powdery mildew ?
A shopper on Apr 16, 2017
BEST ANSWER: I have only used this for lowering the acid level in wine. I have always used Captan 50 for powdery mildew. In searching the web I see that it can be used for that purpose, I will try it.
Thank you
