Short barrel single barrel rye barrel proof is a type of whiskey that is made from rye grain and aged in a single barrel for a short period of time. This type of whiskey is usually bottled at a higher proof than other whiskeys, usually between 120 and 140 proof. The higher proof allows for more flavor to be extracted from the barrel, resulting in a bolder, spicier flavor profile. This type of whiskey is often enjoyed neat or with a few drops of water to open up the flavors.
