Dear Dr. Vinny,
We recently put some cream Sherry on our list at the restaurant where I work. What makes it a "cream" sherry?

Dear Lesley,
Cream Sherry doesn't have any dairy in it, but it is sweet and dark, in the oloroso style. How did it get its name? The story goes that a woman attending a Sherry tasting in the late 1800s sampled a variety of traditional Sherry, which was nicknamed "Bristol's Milk" (named after the British port of Bristol, where Sherry was routinely shipped). After tasting the new, sweeter, more unctuous (and as-yet-unnamed) Sherry, she declared, "If that is milk, then this is cream," and the nickname stuck. Because of its style, cream Sherry is recommended as an after-dinner drink, served over ice or perhaps on the side with a cup of coffee.
