AIChE Beer Brewing Competition


With the support of AIChE and the Young Professionals Committee, come showcase your chemical engineering skills by participating in the AIChE Beer Brewing Competition (ABBC). ABBC will allow AIChE entities (local sections, divisions, forums, etc.) to create teams of two to five U.S.-based professional members over the age of 21 (undergraduate students not eligible to participate), with at least one member under the age of 35, to brew their own beer in any BJCP style category. Professional beer tasting judges will then score beers according to a standard beer tasting rubric. Teams will also flex their chemical engineering muscles through a poster competition describing their processes and creative design that has gone into their brew. The prizes are big, the processes are batch, and the competition is exciting.

2023 AIChE Beer Brewing Competition (ABBC)

The 2023 competition will be held on Sunday, November 5, 2023 at the 2023 AIChE Annual Meeting.
