blind tastings
I have been hosting blind tastings and posting the results for over 20 years. Usually based on a theme, such as a specific appellation or category of wine, these are normally done behind paper bags to ensure a lack of price or label bias. Each taster brings a bottle of his or her choice to the gathering, based on the given criteria.
All bottles are bagged and labeled with a number, then poured randomly. Each wine is poured into a separate glass of the same shape and size. Tasters are asked to vote for their top four bottles, and scores for all tasters are added up for our results.
