Cloudburst Brewing’s Boom. Roasted! Coffee Porter

Steve Luke says about this coffee porter that was brewed at Cloudburst Brewing earlier this year: “I think lighter roasts can be less astringent and acrid compared to darker roasts, so they meld a bit better with darker and roasted malts in the beer.”

BREWER’S NOTES

Our A30 Corporate yeast strain is banked at Imperial Yeast in Portland, Oregon. It’s a publicly available strain, by request. The original strain is Siebel BRY96. If you can’t get your hands on A30 Corporate or Siebel BRY96, Safale US 05 is another alternative.
