I don't drink as much Zin these days as some here, but I do have some affection for the grape. When a recipe for "smoky pork chops with black bean relish" (I realize Cinco de Mayo is mostly a Corona thing, but Betsy wanted to go at least Southwest) suggested Zin as an accompaniment, I bit. There was also a "Mexican shrimp cocktail" but I went with water for that.
The 1998 Dashe Dry Creek Valley Zinfandel seemed thin and almost anemic at first sip. Maybe I should open a Riesling. But within 5 minutes it had put on weight. Some zinnish blackberry and brambles, but overall it ended up reminding me more of a (tasty) midweight claret. Sweet dark fruit, a little cedar and pencil shavings, just a hint of cocoa. good length. Got better and better over couple hours. A bit of smoke. Last glass is the best. I still think most Zins are best young, but this one aged well. B+/A-
Grade disclaimer: I'm a very easy grader, basically A is an excellent wine, B a good wine, C mediocre. Anything below C means I wouldn't drink at a party where it was only choice. Furthermore, I offer no promises of objectivity, accuracy, and certainly not of consistency.
