Grape Powder

Is the grape powder on also where the wine yeast comes from? - Alana in Oceanside, CA
The grape powder is called bloom grape or bloom for short. You’ve probably noticed this before on soft fruits like blueberries and plums and such. It’s a waxy covering that protects fruit from moisture loss and certain types of diseases. The grape powder is flavorless and doesn’t have any effect on juice or wine.
Keep in mind also that some of it is dust as well. Until recently, many believed the white stuff was in part what caused yeast in wine which is responsible for the wine fermentation process. Make sure you wash them first before eating but then again, I’m sure that there are a few of you out there that like having adventures with tasting things au naturale. Cheers!!
