Blind Cupping Randomizer

Paste your sample names, randomize their order, then serve them under neutral labels. Keep the generated key from tasters until the session ends.

Samples

What it does

This uses a browser-side shuffle to generate a label-to-sample key. It supports informal blinding, but it does not replace a formal sensory protocol, sample preparation standard or statistical design.

Good practice

Use neutral labels and preserve the key separately. Randomizing order does not remove every possible bias, so report the session context when sharing a result.

How to use it

  1. Enter one private sample name on each line.
  2. Select Randomize labels to create a fresh label-to-sample key.
  3. Prepare and serve samples under the neutral labels only.
  4. Keep the key away from tasters until notes are complete, then reveal it when the group is ready.

When this helps

This is useful for an informal comparison of beans, recipes or grinders when you want tasters to focus on what is in the cup rather than the sample name. It does not control water, serving temperature, participant expectations or other sources of bias by itself.

Frequently asked questions

The randomizer runs in the current browser. The page does not ask you to create an account or send the sample names to Brew Bench.
No. Formal sensory work may require a defined protocol, standardized preparation and an analysis plan. This page only creates an informal blind-label key.
Use a number your group can prepare and taste consistently. Fewer samples can make it easier to keep temperature, water and service timing comparable.
Yes. A new shuffle makes a new key, so copy or record the final key before serving samples.
