It’s one of the county’s smallest beer-making operations, Poway’s lone brewery, and it’s been going strong for nearly 20 years. An institution devoted to German lagers long before they became uber popular, Lightning Brewery has been guided by owner and brewmaster Jim Crute, a retired scientist who decided to put his smarts to work following his passion for brewing. In this segment, Marty and Paul taste a pair of beers that will be on tap at Lightning’s October 18 Oktoberfest celebration: the Biergarten Helles and the Export-style Pilsner.
