I just made some Edwort's Apfelwein for the first time. I used Mott 100% Apple Juice. I had a 5lb bag of corn sugar and no scale to weight the sugar, so I made a guess at 2lb. When I was done, I think I ended up using half the bag. Making it 2.5 lb, will this be OK? Next time I will buy 1lb bags or buy a scale.
