Which heirloom barley variety is known for its use in British ales?

Maris Otter is widely recognized as a premier heirloom barley variety extensively used in British ales. This two-row variety was developed in the 1960s and has become a favorite among many English brewers due to its reliability and excellent malting characteristics. Maris Otter is particularly valued for its rich, nutty flavor and ability to contribute a smooth, malty sweetness to beer, making it especially popular in traditional British ale styles, including pale ales and bitters.

The use of Maris Otter tends to yield a well-rounded malt profile, ideal for creating the complex flavor profiles characteristic of British ales. Its growing popularity among craft brewers has contributed to its status as a staple in the brewing industry, emphasizing the connection between heritage grains and their influence on brewing traditions.

Other varieties, like Harrington and Klages, don't have the same level of recognition in British brewing traditions, and while Hana may be utilized in certain contexts, it is not specifically associated with British ales in the same way Maris Otter is. This distinctiveness and contribution to the brewing process help position Maris Otter as the correct choice.
