Most spirits can be enjoyed without the addition of any other mixers. Drinking a spirit “neat,” or without anything else added, allows you to enjoy the flavor of the alcohol as well as any tastes left over from the original plant matter. There are those who claim, especially with whiskies, that a drop of spring water helps the flavor come through.
And, as is clear at this point, the variety of mixed drinks that rely on spirits as a base is virtually inexhaustible. Find a spirit, figure out where to buy alcohol online, google some cocktails, and get ready for a tasty, if somewhat hazy, adventure!
