This is my first year making wine from Lodi Juice. Malbec is doing great, currently sitting in carboy for 2nd fermention. Chardonnay was racked into carboy and I noticed these white sperm like organisms floating up to the top and then dissolving. They differ in size and seem to be alive. I dosed the 6 gallons with necessary amount of potassium sorbate and they're still there. Kind of worried because NO ONE has any clue what these swimmers could be.
