Are you a fan of snappy, back-talking zins or do you prefer those of the gallant, well-mannered persuasion? These extremes and everything in-between will be poured at the 19th annual ZAP (Zinfandel Advocates & Producers) Tasting this Saturday at San Francisco’s Fort Mason.

In light of this colossal pool of zin to be poured Saturday, I did a blind preview tasting. With 300-plus wines sent in, I was determined to taste at least one zin from every winery.

Our Wine of the Week (WOW) winner is the 4-star rated Ridge, 2007 Geyserville California Zinfandel, $35, (14.4 percent alcohol.)  You may wonder how it earned WOW status since many zins out-scored it with a 4.5 star rating. Good question. Our WOW pick is always chosen after considering  several factors — availability, price point and star rating.
