Which type of barley has smaller kernels?

The answer identifies six-row barley as having smaller kernels. This distinction is rooted in the structural differences between the two types of barley. Six-row barley is characterized by its genetic makeup, which typically results in smaller and somewhat denser kernels compared to two-row barley. In contrast, two-row barley, which has a different arrangement of kernels, usually produces larger and plumper grains.

Small kernels in six-row barley may be advantageous for brewers who prioritize certain aspects of malt flavor and fermentation profiles. Furthermore, the size and shape of the grains can influence the efficiency of the malting and brewing processes. Generally, two-row barley is favored for brewing high-quality lagers and ales due to its larger kernel size and higher extract potential, while six-row barley finds its use primarily in certain beer styles and animal feed.

This understanding is crucial for brewers and cicerones who may wish to select specific barley types based on the kind of beer they want to create, affecting both the flavor and brewing efficiency.
