As an expert sommelier and brewer, I can confidently say that Three Barrels is not whiskey, but rather a brandy. Whiskey and brandy are two distinct types of spirits with different production methods, ingredients, and flavor profiles.
Whiskey is made from fermented grain mash, which can include barley, corn, rye, and wheat. It is typically aged in wooden barrels, which imparts flavor and character to the spirit. The aging process can vary, but in general, whiskey is aged for a minimum of three years. The resulting spirit is known for its complex flavors, ranging from smoky and peaty to fruity and spicy.
On the other hand, brandy is made from fermented fruit juice or wine. The most common fruits used for brandy production are grapes, but other fruits such as apples, pears, and cherries can also be used. The fruit juice or wine is distilled to increase the alcohol content and then aged in oak barrels. The aging process for brandy can range from a few years to several decades, depending on the desired flavor profile. Brandy is known for its rich, fruity flavors and smoothness.
While I haven't personally tasted Three Barrels brandy, I can speak to the general characteristics of brandy based on my expertise. Brandy is often enjoyed neat or on the rocks, allowing the flavors to shine through without dilution. It can also be used as a base for cocktails or added to various culinary recipes for an extra depth of flavor.
