This Saturday and Sunday, October 17-18, Trade Route Brewing celebrates the grand opening of its new brewery and tasting room just south of Auburn. Seems like a crazy move to go south, but Black Raven in Redmond knows the value of being one of the only fish in the pond. The festivities begin at 11 a.m. each day. (Trade Route Brewing, 1091 Valentine Ave. S.E., Pacific, Wash.)Pike Brewing will hold its 20th anniversary party this Saturday, October 17, beginning at 5:00 p.m. in the museum room. Stop in, if only to try two-limited edition beers brewed especially for the occasion: the Pike Entire Wood-Aged Stout (XXXXX Stout and Imperial Stout aged together in bourbon barrels) and the Pike Triple Kriek (Monks Uncle Tripel, brewed with brett yeast and local Bing cherries, then aged in wine barrels). There will be music and pale ale birthday cake at 7:00 p.m. (Pike Brewing, 1415 First Ave.)We will announce the Seattle Weekly Homebrew Contest winners this Saturday, October 17, at 2:00 p.m. at Brouwer’s Cafe in Fremont. We received more than five dozen entries in our first of this sure-to-be yearly competition, and we will share the six category winners, along with a best in show. It all culminates in the tapping of the winning brew, made by Big Al Brewing. (Brouwer’s Cafe, 400 N. 35th St.)
