It is not new to have a main brewery in Hood River and a taproom in Portland. Full Sail trod that path first. And now a second brewery will be bi-river. (Columbia and Willamette)
Ferment comes from former head brewer at the excellent pFriem Family Brewers, Dan Peterson. The plan is to eventually brew in Hood River and operate their taproom at the new building called The Yard on 3rd and Burnside.
The brewery is aiming for a fall 2016 opening. You can read more about them and why they are so anticipated HERE.
