I have what maybe a newbie question but I can't seem to find the answer on my own. What does stirring the lees(I would guess during primary)do for the fermentation? If I'm wrong tell me but doesn't the yeast only start making alcohol when the easily avalible oxygen is used up and it start converting suger for it's oxygen. Wouldn't opening the primary fermentor, putting in a lee stirrer, and stirring add oxygen back into the must? I could see picking up the primary and maybe sloshing the must inside to break up the yeast pack if it was still eairly in the primary, but then I have read that can lead to foaming. Like I said newbie question, but with my first one gallon in primary and the other in secondary I am newbie. It's still my time for stupid questions.
thanks for the help and for the great site
