Does anyone know of a good place to get all the various formulas used to compute final gravity, color, bitterness, etc. in your beer?
Open-source brewing software:
- brew-journal: http://github.com/jsled/brew-journal (disclosure: my project :) docstring comments in the computational classes in app/models.py have links to references).
- qbrew: http://www.usermode.org/code.html
- brewtarget: http://brewtarget.sourceforge.net/
Non-open-source brewing software:
- Brewer's Friend has a number of excellent online calculators distinguished by having documented details on their approach and the references/formula used.
Hopville has a nice online recipe calculator: http://beercalculus.hopville.com/recipe. You can store your recipes on the site too which makes it very easy share your awesome creations with others :)
Jamil has a great pitching rate calculator on his site, which you might be interested in.
The Beer Recipator is another good one.
I am a fan of BeerSmith. Performs tons of calculations, maintains recipes, and all around is a handy tool to have. There is a trial version to get a feel for it, and for me it was well worth the cost to get the full version.
Have a look at captainbrew.com. You can create recipes, adjust gravity or bitterness, scale a recipe, create brew sessions and many more. There are also other calculators included like Yeast Pitching Rate, Priming Sugar, Keg Carbonation, ABV , Sparge Water, Washed Yeast.
