hi there you jolly brewers, I recently started some ruhbarb wine and at the stage of fermenting, Iam following an old recipe from CJJ Berry book 1982 should go ok but a couple of questions please. Iam keeping the temp steady by a brewing belt its bubbbling away ok but no signs of any brown scum on top as you see when fermenting other beer wines etc is this right??? Also added camden tab with the fermention is this wrong??? dont no why did this?? :hmm: :cry:
