Does anyone know of a good place to get all the various formulas used to compute final gravity, color, bitterness, etc. in your beer?

(Wow, I can't submit a constructive link post because I'm a newbie. bear with me, and upvote me so I can be similarly constructive in the future! :)

Open-source brewing software:

  • brew-journal: github.com/jsled/brew-journal (disclosure: my project :) docstring comments in the computational classes in app/models.py have links to references).
  • qbrew: www.usermode.org/code.html
  • brewtarget: brewtarget.sourceforge.net/


  • "Technical Library at the Brewery": www.brewery.org/Library.html
  • Home Brew Digest archives: hbd.org/archives.shtml ftp, but often quite a high s/n ratio.

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 :)

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.
