I’m on a MAC …I’ve tried them all. And since you can run many Windoze programs on a Mac using Crossover (without the need to install Windoze OS at all), I’ve test driven almost all of the brewing softwares including ProMash.
In my opinion, if you’re running on MacOS, Beer Alchemy is definitely the way to go. BeerSmith is not bad, but in my opinion Beer Alchemy overall seems to have a much better layout and is more intuitive to use.
I suspect most of these softwares are using the same basic algorithms under the hood for the calcs, but in the course of testing, it seemed that BeerAlchemy consistently delivered the most accurate results, so that’s the one I ultimately purchased.
Although I always turn off the pesky style guidelines feature, it is there (and seems to work quite well) for those who deem it important to brew to competition style parameters.
So to me, Beer Alchemy is the best of the lot. No contest.
I have no connection with the people who wrote it or the company that sells it.
In fact, I stubbornly resisted relying on brewing software (or even using it at all) for the most part until last year or two. I haven’t discarded my spiral bound notebook, but I check all of my numbers and targets with the software and am very pleased with the way it performs.
