What is a Zwickel?

A zwickel is the the valve or sample port mounted at the outside of a cask or tank. This valve allows the brewer to take samples for assessing the brew's progress during fermentation.

What is Zwickelmania®?

Zwickelmania® is the annual celebration of Oregon craft beer when Oregon Brewers Guild member breweries open their brewery doors, inviting the public to come sneak a peak behind the scenes. Participating breweries offer special events such as meet-the-brewer, beer tastings, brewery tours, and food & beer pairings. We hold the event on two different weekends in February - the first in the Portland area, and the second statewide.
