High Quality Content by WIKIPEDIA articles! A malt house, or maltings, is a building where cereal grain is converted into malt by soaking it in water, allowing it to sprout and then drying it to stop further growth. The malt is used in brewing beer, whisky and in certain foods. The traditional malt house was largely phased out during the twentieth century in favour of more mechanised production. Many malt houses have been converted to other uses, such as Snape Maltings which is now a concert hall.
