Blended bourbon is the product of blending different types of whiskeys and sometimes also neutral grain spirits, coloring, and flavorings. It is generally the product of mixing one or more higher-quality straight or single malts with less expensive spirits and other ingredients
Single barrel bourbons come from a particular barrel, which is usually hand-picked by the master distiller based on the degree of fullness and richness in terms of body. A single barrel is the bourbon from only one barrel, “watered down” to a desired proof.
Small batch refers to American whiskeys which have been distilled in limited quantity. The most commonplace meaning of the term is for a bourbon or rye whiskey which is distilled in quantities of around 1,000 gallons or less.
Typically, a bourbon mash bill includes three ingredients: corn, rye and barley. In order to create a wheated bourbon, distilleries replace the rye portion of the mash bill with wheat to create a “wheated” or “wheater” bourbon. wheated bourbon is softer and often sweeter.
A bourbon in which the second major ingredient is rye is known as a high-rye bourbon. Rye is a spicier, richer grain than either corn or wheat, and high-rye bourbons are usually spicier and richer as a result.
