Wall Street Journal is getting behind Hop Extract Craft Beers!

An article posted on June 23, 2016 in the Wall Street Journal, (can be read here: www.wsj.com/articles/bitter-truths-1466715201) is siting some very good beers and very well known brewers that are using CO2 extracted hops including Lagunitas, Stone and Sierra Nevada.

Here at CF Tech, we have been supplying systems for small scale research of hops extractions, including fractionation of extracts to provide insight into the ideal operating conditions for the brewers best tastes, we have had the pleasure of extracting Cascade, Amarillo and Zeus, among other hops in-house over the years. The articles "technical" terms don't sound quite exact, but close enough : ) Our method of extraction uses Supercritical Carbon Dioxide (SCCO2) which is CO2 above it's critical state, where it is not quite a liquid nor a gas and has superb extraction qualities. CO2 is abundant, economic, nonhazardous and nonflammable in extraction processes.

Another interest of the major hops extract suppliers is the need to recirculate and recycle the CO2 to save on operating expenses. This is another aspect of design and fabrication that CF Tech has experience in. We provide storage tanks for recirculation on bench and pilot systems as well as the larger systems. This ensures continuous experiments keep going without the need to pause and switch cylinders and tanks, saves on gas costs, and to lessens responsibilities of the operating team from venting CO2 into the atmosphere.
