Understanding Diacetyl

IBU calculators most often used by brewers were developed prior to the popularity of adding massive hop additions after the boil. As brewing techniques evolve, the way we measure IBUs should too. A new model, dubbed SMPH, accounts for factors that have previously been overlooked, including separating isomerized alpha acids from auxiliary bittering compounds.

Substituting hop pellets with CO2 hop extract increases yields and can produce cleaner, brighter beer while maintaining hop varietal character. Learn more about how hop extract is made and how to use it in your brews.
