These wines are for acid lovers-to me in a good way, as I love tangy, high acid wines. The highlight was probably the Alexander Valley Merlot, which had warm plum fruit but a very savory, yes tangy character. The Zinfandel was a mouthful of zingy berry fruit with a lovely tangy cranberry finish. They also have a kitchen sink blend in a liter jug. Classic food wine, to be honest. It made my mouth water!
Anyway, take my tasting notes with a grain of salt. These were tasted after hours of climbing and drinking sports beverages, so your mileage may vary.
