I like wine. I like to drink it; I don’t need to understand why I like to drink it, but I’ve learned in the past few years that a lot of livelihoods depend on me wanting to know why. So when I travel to California’s wine country, which has become an annual event to visit friends, I include a winery tour, not so much for the sake of those livelihoods,  but for the same reason people who travel to New York and Paris visit MOMA and the Louvre: to advance their knowledge of art and culture sufficient to become annoying at parties.
