Added Yeast to Crushed White Grapes BEFORE pressing

[pietro]

Hoping someone can give me advice; I mistakenly added yeast to my crushed white grapes BEFORE I pressed (late yesterday evening). This evening, I'll be pressing the grapes. Should I do anything at this point? Add the same quantity of yeast again after pressing?

Thanks!

It all depends..

Did you treat your grapes with any K-meta before you added your yeast?

If you did, then you stand a good chance that your cultured yeast may not take hold. If this is the case, I would simply add more yeast after pressing (the same amount)

If you did not add any k-meta, then just go ahead and press your wine. No need to add more if the yeast goes active.
