I added 2 oz. of dextrose to my 1100mL batch of Apfelwein that I started on Friday evening. My dextrose addition equals about 7 oz. per gallon of apple juice. the juice had an OG of 1.046 and the dextrose boosted it to 1.058. I pitched an entire packet of Lalvin EC-1118 into my tiny fermenting vessel and it took off in record time! If it ferments down to 1.000 I'll get 7.6% ABV, which I'm very happy with
1.000 is pretty dry though, so I'll undoubtedly back-sweeten it with some honey or apple juice once I stabilize it.
