Brewing. Workers inspecting a steel mash tun at a brewery. The mash tun is where the milled grain, typically malted barley, is mixed with hot water. This allows the enzymes in the malt to break down the starch in the grain to form sugars such as maltose. Photographed at the Ostmark Brewery, Kalinningrad, Russia.
