Ferment Brewing Company – The Sentinel

From the brewery:
The Sentinel mixed culture saison was first fermented with our own yeast strain isolated from the wild on Mt. Hood. It then spent the better part of a year in French oak wine barrels where Brettanomyces was allowed to develop. Finally, a charge of Doug Fir tips handpicked from the forest surrounding Hood River was added to create an ale mildly sour and wildly complex
