The triangle test, on paper.

Two bottles you already own, three matching glasses, and somebody willing to pour. One page. The method is about 150 years old and needs nothing from us.

Three identical nosing glasses of whiskey in a row — a blind triangle test
Two the same, one different. The sheet below runs the whole test on paper.

How to run it

  1. Pick two whiskeys. Similar ones make a better test than opposites. Call one A and the other B.
  2. Print the sheet and fold along the dashed line. The bottom half is the key — the pourer keeps it, and you never see it.
  3. Each round is three glasses, poured in the order the key gives. Number them 1, 2, 3 left to right.
  4. Taste all three and mark which glass is different — not which you preferred. Water and a plain cracker between rounds.
  5. Spread eighteen rounds over several nights. Your nose fatigues fast, and a tired nose turns this into a test of endurance.
  6. Count the ones you got right, then see what the two numbers mean.

Why eighteen? You would get one in three right by pure luck, so a handful of correct calls means nothing at all. Eighteen is where the arithmetic can start to tell skill from chance. Fewer is not a failure — it is simply not yet an answer.

Running it for a table? Eight guests doing three rounds each is 24 calls, already past the line. Add everyone's totals together.

Fold here — pourer keeps the bottom

Pourer’s key. Pour left to right in the order shown. The bold number is the odd glass — the taster must not see this half.

When you have your two numbers, the calculator is here — and it will tell you honestly when the count doesn’t mean anything yet.
