  • 2008 BJCP Style Guidelines: The official 2008 BJCP Style Guidelines can all be found here. This is where the numbers came from.
  • Balancing Your Beer with the Bitterness Ratio: This is from Brad Smith at BeerSmith. It explains how to get the BU:GU ratio in the first place.
  • BeerSmith: My favorite brewing software. Free trial, but you have to pay for the full version. It's worth it.
  • Brewtarget: The best free brewing software I'm aware of. Not as comprehensive as BeerSmith, but gets the job done for many.
