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

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

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

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

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.
