America's first lager brewers arrived in the mid-19th century from Germany, where the golden, hoppy pilsner style of lager was just then catching on. But German brewers were making lagers long before that, in a wide range of styles. There's dry, refreshing schwarzbier, or black beer, and dunkel, or dark. There's sweet, copper marzen, enjoyed at Oktoberfest, while malty bocks, aged through winter, are drunk in spring. Subcategories of bock include floral Maibock, rich doppelbock, and eisbock, traditionally lagered in ice caves and skimmed of freezing water to concentrate its potency. The pale, bland American pilsners made today by the country's biggest breweries are a far cry from these flavorful beers, but stateside craft brewers are now making lagers of depth and complexity in both traditional and innovative styles.
