Schnapps by John Spottiswood.

In the United States, schnapps are flavored liqueurs based on neutral spirits. The flavorings vary widely, and include peppermint schnapps, root beer schnapps, peach schnapps, and cinnamon schnapps. These flavored schnapps can be sweet or dry, but most are sweeter and lighter than a typical liqueur. In Germany and Scandinavia, schnapps refers to any spirit that's dry and potent, like kirsch and aquavit.
