M&S Czech Lager is an alcohol-free lager from the Czech Republic, produced by the Litovel Brewery exclusively for M&S. It uses Zatec hops, a variety grown in the Czech town of the same name. The beer is dark amber in the glass, with a substantial frothy head. The aroma is mild malt sweetness and bready. The hops come through as very slight and herbal. The taste is rather dry.
