By that logic, a pencil & paper would be even better!I used Beersmith on my mac via Parallels, but I have to say the best thing out there is excel. Learn the formulas and plug them into a plain old spreadsheet. It will make you a much better brewer once you learn the basic math behind your brew. I don't even use Beersmith anymore, I just have an excel spreadsheet dialed in to my system.
That's not a bad idea. I had it running on Linux via Crossover/Wine for about a year. I think Beersmith is the overall winner of the brewing software out there. It's just so sane in its approach to everything.I ended up using Beersmith in VMWare because I couldn't find anything comparable.
