One of the most interesting wine courses I attended was to taste all wines in black stemware. We were unable to discern if the wine was red, white, or rose. They even went further and served us white wines not chilled, and red wines chilled. Then to really mess with us, they matched the wines with various music. It provided a new perspective of wine without a visual or temperature reference, and the music really played with the mind. This is a simple thing to do at home with some friends.
