I have six buckets of red wine and one bucket of white in their 6th day of fermentation. When I open the lid to take a reading or give it a stir, I noticed a fruit fly floating on top. I remove the insect and find another the next time I open the cover. Easy to see in white wine not so much in red. Question is are they harmful to the wine.
