I brewed this the second week of January. Kegged it... and tapped it Feb 21st... and now its gone. :P Amazing recipe. My only change was adding more lactose (3/4lb instead of 1/2lb). Brewing this again next week.
it looks like its decent for doing simple calculations, but it doesnt give much info on the specific grains. I just started using beersmith and i like it a lot. Im sure a lot of people will recommend beersmith
