Henry's or Blitz

They are types of beers specific to Oregon (where the movie was shot and took place). Henry and Blitz are both owned and operated by Henry Weinhard’s of Oregon.

Although, even if you don’t know this, one should be able to figure this out, as Ernie (Burt Reynolds) asks Mike (Casey Siemaszko) the question of Henry or Blitz as he’s looking into the refrigerator, and upon Mike’s answer he pulls out two bottles of beer.
