It's rightly pronounced the way you think you'd say 'Jeréz,' the Spanish town that anchors a major portion of its production, and it's fortified with brandy, which adds flavor and dries it out. The brandy part makes Sherry a bit of a renegade-you can taste the liquor stuff right away, and the taste does require some getting used to.
You get that idea as you take in your glass of Osborne's Manzanilla Fila, as it definitely makes you sit up and take notice. There's a crackly, exceedingly dry quality here (a trait of the best Sherries), and amid this entry's ghostly pale appearance, you may mistake it for vodka. But all those things are designed to command your attention-this is what's called an aperitif, which means it's meant to be drunk by itself or with a very small item (like an olive or two) prior to a larger meal. It'll definitely give you something to think about before you sit down to chow.
Some Sherries are designed only for cooking; those vintners will throw a bunch of salt into their product to make it undrinkably dry. But Osborne is potable indeed, igniting a very real curiosity about its unusual taste and look. It's an instant conversation piece-and at $11 a bottle, a dirt-cheap one at that.
