$5 donation required for a Johnny Walker "education" session - with appies and tastings. Hopefully they'll provide the same useful data I garnered from the Guiness tastings (it's okay honey, one more beer won't pack on the pounds, Guiness is low cal and low carb)

Not sure if they're throughout the US, but I found events in San Francisco and LA when I entered CA for the state.
