Blind test vs semi-blind test
Blinding is a scientific method to avoid bias in research. In open taste tests comparing different product brands, consumers usually choose their regular brand. However, in blind taste tests, where the brand identities are concealed, consumers are more likely to choose a different brand.
There are two main methods for tasting beer. These are:
- semi-blind test
- blind test (strongly recommended!)
In a semi-blind test, the tasters know which brands are included in the tasting, but they don’t know the order in which the beers will be served. This method can cause certain expectations and distractions, making it difficult to obtain objective and unbiased results.
In a blind test, the tasters don’t know which brands of beer will be included in the tasting. This completely eliminates the influence of preconceived notions that could otherwise greatly influence the results, especially with a topic as subjective and emotional as beer choice.
For obvious reasons, a blind test is preferable where possible. For example, the beer reviews on tastebeer.com.au were conducted as blind tests (read here how we conducted our beer tastings). Scientific principles were applied to eliminate outside factors and bias as much as possible. We have condensed many of these principles for everyday use so that you can enjoy a two-person beer tasting any time, anywhere.
All our taste tests presented on this site can be conducted as double-blind tests, where both the helper who servers the beer and the taster do not know which beer is being sampled. Typically this requires a lot more preparation and is not required unless you plan to publish your results in a scientific journal!
