Do you know where your whiskey comes from? If you want to be able to answer that question with something a little more specific than “from a bottle,” you might want to pick up a set of Whiskey Taxonomy Glasses as an early Christmas gift this year. The glasses come in a set of four and there is one for each major type of whiskey: Irish Whiskey, Single Malt Scotch, Scotch and Bourbon. On each glass, you’ll see the names of familiar whiskies divided into families by the brands that own them. It’s like a family tree for your favorite spirit. The glasses are larger than a double rocks glass, which provides plenty of space for all the text in a legible font, but not so large that you can’t use them for whiskey. Just think of it as having plenty of room for an extra large ice cube, even if they are bigger than some of the other glasses in your collection.
