I love to have Rosenblum Zinfandel with barbecued meats such as tri-tip or steak.
Rosenblum has over 40 different Zinfandels, many of them vineyard specific. It would be hard to find one that is not fantastic. Some of the great ones are: Eagle Point Vineyard Zinfandel and Rockpile Road Vineyard Zinfandel. Even their Zinfandel Cuvee that sells for around $9 a bottle is nice, a perfect wine to pick up a case for everyday drinking.
Cheers!
