I mostly made it a point to make it out here when I was in the area last weekend for reasons entirely unrelated to wine tasting, because I wasn't even sure if they still existed, the most recent previous review having been from 2013, and with not much info on their website... but I asked Calera and they assured me that Guerra was indeed still open, they're just more well known for their events than for their wine (the pourer at Guerra agreed with that assessment), so they don't necessarily attract yelpers. So I made the trek (and it is indeed a trek: it's about a mile of gravely dirt roads from the entrance, so be prepared for that - a couple times I felt like I was going the wrong way and was about to drive into their actual fields, but nope, their tasting room is just really out of the way.)
Finally made it to the tasting room - a converted little barn with no electricity or anything, and one pourer (but that's all they needed, since it was so out of the way). Surprisingly, a couple other groups actually did show up while I was there - they sounded local. Anyway, a very friendly and knowledgeable pourer poured me a total of 5 tastings (everything they had) for $10: one off-dry white, and 4 reds.The off-dry white was a viognier - I've never had a viognier that was anything but either bone dry, or late harvest, but this one was gorgeous, delightfully refreshing for summer, and perfectly chilled. I say that because, by contrast, with no electricity and being the summer, the reds were quite warm, and that detracted quite a lot. So I really can't even say how good the reds were, though my educated guess would be "decent", because they definitely weren't that great at like 85 degrees. So my recommendation would be: check this place out sometime other than the middle of the summer (though the tasting room itself had a great breeze running through it, at least).
They do waive the tasting fee with a bottle purchase, so obviously I bought a bottle of that viognier, and I don't regret it at all. But they really need to figure out a better solution to keeping their reds the right temperature when it's hot out. read more
