In November/December 2005 I conducted a "blind test" here in Germany during which a volunteer from a Newsgroup I was reading had to sample and rate 17 different malt whiskies without knowing what he was drinking. Later I compared his results to the age and price of the whiskies involved.
These pages describe the experiment in detail. I had initially only provided them in German, but now an English version is also available.
A similar experiment with 56 participants was conducted in late 2006.
