I attended a class in January, 2015, called "Wine, Cheese and the Pursuit of Happiness". The teacher, Jonathan Alsop, is really informative and wickedly funny.
The class began with his "Seven S" System of Wine Tasting:
See, Sniff, Swirl, Smell, Sip, Swish, Spit
Beginning with "See", he asks, "What does the wine look like? Clear as water, black as ink, or in between?" He explained that you should hold the glass up to the light. "This magnifies the unbearable pomposity of the wine lover". -- The class laughed and followed him right down the path of the rest of the Seven S's.
The next S is "Sniff". Here, he advised that it's meant to be a quick check. Make sure the wine is not smelling wrong - like jet fuel or an undergraduate era shower curtain.
After bringing the students to the level where we all deployed the same 7S techniques, we then turned to actually tasting the 7 wines, 6 cheeses and 1 dinner that rounded out the Boston Wine School curriculum for that evening. The first wine was NV Bellussi Extra Dry Prosecco, for which Jonathan led with the description: Light Carbonation, Very Soft, Welcoming to People, "Shut up and drink me".
A class at the Boston Wine School teaches to all levels (well, maybe not to winemakers) and is a really nice social experience limited to 14 people per class.
