BeerAlchemy is designed to help homebrewers create great beer. It takes the drudgery out of recipe formulation and looks after all your recipes too.
BeerAlchemy was designed and written on a Mac, for the Mac by a keen homebrewer.
BeerAlchemy makes recipe creation easy and offers support for extract and full mash brewing.
It offers an extensive built-in database of brewing ingredients and you can also edit and add your own.
I'm not a home brewer, but I found this app quite interesting. It was like a step behind a curtain. I've noticed that the recipes are well organized and comfortable to operate. The ability to edit the ingredients list must be handy.
