Making wine from grape juice for first time. Had six gallons of Barolo for six weeks (went through primary in pail for roughly one week and placed into Carboy for the last five weeks. Removed Airlock the other day and placed natural cork stopper to begin the aging. Yesterday noticed a small kind of white cotton like swirl on top of the wine and two or three tiny little (what I'm assuming are fruit flies) though they are white in color. Is this likely mold? What can be done from here?
