The Glencairn is the official scotch whisky nosing and tasting glass. This is our 6th edition glass in limited numbers (no two editions are the same). One side of our glass proudly displays the Dummies Stamp of Approval. Notice a small line below the logo which is roughly a one ounce pour. Never guess again about how big of pour you had. Purchase of the each glass helps us maintain the website and offset the cost of producing videos. Thanks for your support.
