Controlled Testing, Reliable Results
Central Location Testing (CLT) brings consumers to a controlled facility where products are prepared, presented, and evaluated under standardised conditions. This eliminates the variability of home environments and enables precise side-by-side product comparisons.
When CLT Is the Right Method
- Taste and sensory testing where preparation and temperature matter
- Side-by-side product comparisons requiring immediate evaluation
- Prototype testing where products cannot be shipped home
- Shelf or packaging research requiring a simulated retail environment
- High-volume rapid screening where speed is critical
CLT Design Options
We design CLTs as monadic, sequential monadic, or paired comparison tests. For sensory research, we apply triangle tests, duo-trio tests, and hedonic scaling. Sample sizes typically range from 100-300 per cell depending on the design.
Our CLT Facilities
We operate and partner with CLT facilities across South Africa, including Johannesburg, Cape Town, and Durban. Each facility offers preparation kitchens, individual tasting booths, and group interview rooms.
