Narrative 15-1
Pacific Western Brewing Company is a microbrewery in Prince George,B.C. It produces Ironhorse full-flavoured lager,a dark beer called Pacific Schwarzbock,and several other beers. Its owner Kazuko Komatsu believes the brewery's competitive advantage comes from having hired an experienced German brewmaster,Henrik Braun,to oversee the production of its beers. The brewmaster checks all of the ingredients before they are mixed together to make sure that each component is of the highest possible quality and rejects those that are not. After the beer has brewed,the brewmaster runs several tests on the beer to check for taste and clarity and throws out barrels that are cloudy and/or bitter.
