Winter vs. Spring What is the difference between winter and spring barley, and what the *%^&(+ is a facultative barley? The three growth habit classes of barley are winter, facultative and spring. A winter barley is planted in late fall and is harvested the following summer. A spring barley is planted in the spring and harvested the same summer. If you plant a winter barley in spring, it will not flower, or it will flower too late. If you plant a spring barley in the fall, it will (in many temperate environments) die from low temperature injury. A facultative barley can be planted in the spring or the fall, and it is cold-tolerant. There are three principal physiological traits involved: vernalization sensitivity, photoperiod sensitivity, and low temperature tolerance. Vernalization sensitivity means the plant needs exposure to low temperature before it can flower. Winter barleys are vernalization-sensitive whereas facultative and spring types are not. Photoperiod sensitivity means the plant will not flower until the day length reaches a critical threshold. Many winter barleys, most facultative barleys, and few spring barleys are sensitive to short days. Low temperature tolerance is an induced trait. Winter and facultative barleys are more cold tolerant than spring barleys. Since the traits are controlled by different genes our bets are on photoperiod-sensitive, cold-tolerant facultative varieties. http://barleyworld.org/FAQ_sheet.php

Malt vs. Feed • Why some varieties are better for making beer than others • Barley malt is the perfect combination of starch, enzymes, flavors, and aromas for brewing, distilling, baked goods, cereals and confections. There are many types of barley malt – from light to dark – but all are variations on two principal themes: germination and kilning. Different end-uses require different malt quality specifications. Some of the principal characteristics used to define malting quality are protein (low, moderate, or high), malt extract (high), enzyme activity (moderate to high), and beta glucan (low). • Feed barley is used as food for animals. Varieties also differ in their feeding properties but unfortunately feed barley is simply sold by the ton. Feed barley prices are often so low that farmers grow other crops - if they can do so. As a consequence, barley’s adaptability to extreme climates makes it an important feed grain only in areas where it is unprofitable to grow (or import) maize. • Hooded barley is a unique type of feed barley that has hoods, rather than awns. These types are usually cut green for hay or silage. The lack of awns allows for easy chewing by the animals. Malt Feed A rule of thumb is that good malt barley is good feed barley, but not the reverse. In general, malt barley commands a premium over feed barley, but yield less. Many genes determine malting and feed quality; two genes determine the hooded trait. http://barleyworld.org/FAQ_sheet.php Forage

Growth habit: winter, facultative, and spring Highest yields with winter or facultative barley Seeded mid-October and harvested in early July At least 6,000 lbs per acre and test weights > 50 lbs./bu Winter breeding nursery. CBARC. Pendleton, OR 2009
Late spring (March/April) plantings of barley will likely yield less than fall plantings and will require irrigation to achieve maximum yield Spring breeding nursery. Hyslop Farm, Lewisburg, OR 2010
Facultative varieties: plant any time Late winter/early spring (~ February) seeding of winter, facultative, or spring varieties is an option for some growers Spring breeding nursery (foreground) and winter breeding nursery (background). Hyslop Farm. Lewisburg, OR 2010
Principal end-uses are feed, food, forage, and malt Rogue ale hour. OR 2010
Malting varieties must meet specific quality criteria for malting and brewing The maltster and brewer will specify which variety (ies) will be contracted
The food barley market is developing The driver is Beta glucan = soluble dietary fiber Key differentiators are hulled vs. naked waxy vs. normal starch The hull is removed by genetics, de-hulling, pearling, or milling
Forage varieties are hooded – no awns Harvested for hay, green chop, silage Grazed Grain
