Next to Elliott Bay Brewing’s massive brewpub on Lake City Way sprawls another, nearly as massive beer hall, replete with enormous murals and Edison-bulbed chandeliers. As the name suggests, this spinoff project is dedicated to barrel-aged beer. Some brews are Elliott Bay standards given new dimension in decommissioned whiskey, gin, or wine barrels(a straightforward Luna wheat beer saison across the hall becomes an approachable sour after a 28-month sojourn in the downstairs aging room). Others are spontaneously fermented, but everything is big, bold, or funky, and uniformly impressive. The kitchen dispatches meat, cheese, fish, and veggie boards, plus snacks and entrees with the same elegantly hearty vibe as their environs.
