ok this is my first time making wine and I have started with 2 different recipes, both started off almost the same, here is what I did,
added enough water water to cover the fruit
added sodium Metabisulfate
andded acid Blend
the difference is to one batch I also added 3 cans of white grape conncentrate
here is my question, I have been stiring it everday for the past 4 days, and something odd happened to the batch with the conncentrate. yestereday when I stired it it foamed up like head on a beer, however the one without didnt. does anyone have any idea of what is going on? did I mess something up?
