CLT

Central Location Test

A study conducted in a dedicated location where participants test products under controlled conditions.

Why it matters

It allows for comparing products under the same conditions for every participant.

What's missing without it

Without it, everything influences the result: time of day, beverage temperature, what someone ate earlier.

When it is used

For taste tests, packaging, advertising, and prototypes.

How we use it

Recruitment, sample rotation, survey immediately after the test.

Fun fact

The facility must be neutral: no odors, no ads on walls, glass of the same color. The color of the cup can change the perceived taste of a beverage.
