The base spirit of a gin refers to the distillate to which botanicals were added. It’s helpful to think about the base spirit as a vodka-like spirit that the distiller used as a starting point— a blank canvas upon which the gin was designed.But choice of base alone doesn’t mean that you’ll be able to taste it. Depending on choices the distiller makes, such as how many times the base is distilled, or to what strength it is distilled to— there might be no character at all coming from the base spirit.

Many cideries or distilleries from regions where apples are prevalent have been experimenting with an apple base.Apple base can vary based on the type of apples used and the place where it’s used. I know some spirits writers describe a certain distinctive earthy note of Upstate New York apple base spirits as affectionately having a “New York funk.” Given their wide variation and distinctive character, many distillers choose to build around the apple base spirit and use its unique character as an asset.
