Barley grown for brewers malt is called malting barley, as opposed to feed barley, and is divided into two general types; 2-row and 6-row. The most obvious difference between a head of 2-row barley and a head of 6-row barley is the arrangement of the kernels when the head is viewed down its axis. Brewers dont make a big deal about 2-row versus 6-row barley based on the appearance of the barley head, however. The significant differences are found upon closer examination. In general, 6-row malted barley has more protein and enzyme content than 2-row malted barley, is thinner than two-row malt and contains less carbohydrate. There are also flavor differences between 2-row and 6-row and it seems that most brewers feel 2-row malt produces a fuller, maltier flavor and 6-row malt produces a grainier flavor in the finished beer.
