Hey has anyone come up with a good way to handle double or triple fermentations using the Brewers friend tool? Problem is once you have your brew day complete gravity there's no way of tallying the ABV or changes in SG/total volume with extra additions of wort. That I can see?? I'm currently making a Belgian Dubbel brown SG 1.065 at 18L and will then add another wort from 1kg of malt mix in a couple of days, up to 21L. Any thoughts?
