Retain the blind/open distinction, but do not teach the book's triangle exercise as a validated discrimination protocol. A standard triangle test presents two samples of one product and one of another, with the assessor identifying the odd sample. Blinding reduces selected expectation cues; it does not eliminate all bias.
The final chapter contrasts enjoyment with focused evaluation and explains how labels, price, packaging, and context bias perception.
Bryson distinguishes blind tasting that reduces label expectations from open tasting that supplies context, and recommends deliberate nosing, notes and water trials. His page 327 exercise called a triangle test allows three identical or three different samples; this is not the standard triangle-test design.
