This is my first time using a 100 liter ss variable capacity lid. I have 24 gallons of gewurztraminer in the tank. It is stored in my basement and the temperature on the dial is 63 degrees. I have noticed there has been liquid on the floor underneath. I can confirm the liquid is not wine, from tasting it. I. Can also confirm none of the seals are leaking as they are all dry. Is it just condensation? Is this normal? Any remedies other than putting a towel underneath? Thanks in advance.
