Hordeum distichon, commonly known as two-row barley, is a species of barley in the Poaceae family. It is one of the primary species used in the production of malt for beer and whisky.

Description[edit | edit source]

Hordeum distichon is characterized by its two-row spikelet structure, where each node on the rachis produces two fertile florets. This is in contrast to Hordeum vulgare, which has a six-row spikelet structure. The plant typically grows to a height of 60-120 cm and has a robust, fibrous root system.

Cultivation[edit | edit source]

Two-row barley is predominantly grown in temperate regions. It requires well-drained soil and a moderate climate. The cultivation practices for Hordeum distichon are similar to those of other barley species, involving plowing, harrowing, and sowing.

Uses[edit | edit source]

The primary use of Hordeum distichon is in the production of malt. The two-row structure is preferred for malting because it generally has a higher starch content and lower protein content compared to six-row barley, which is ideal for brewing high-quality beer and whisky. Additionally, it is used as animal feed and in the production of various food products.

History[edit | edit source]

The cultivation of Hordeum distichon dates back to ancient times. It has been a staple crop in various cultures and has played a significant role in the development of agriculture and brewing practices.
