Maris Otter is a 2-row, "winter"[1] variety of barley commonly used in the production of malt for the brewing industry. The variety was bred by Dr G D H Bell and his team of plant breeders at Cambridge.
Typically this variety of barley is used to create a pale malt which is the basis of most British ales. It is very popular both in homebrewing circles and among professional breweries in the Anglosphere, many of whom note their exclusive use of Maris Otter in their promotional literature. It is more expensive than other varieties.
Maris Otter is closely related to the Scottish-grown Golden Promise barley.
Okay, ikke en veldig vitenskapelig kilde, men pytt pytt
Golden Promise har jeg aldri prøvd.
