Last Saturday (prior to the gastroenteritis debacle) we toured some wineries with some of Scott's labmates. Sonoma? No. Napa? Nope. Livermore.
Yes, we went south to the wineries in Livermore, CA. The last time I was at a winery was just before we found out we were pregnant with baby girl. So, it's been awhile (17 months) since I've had anything alcoholic, but I have to say, I didn't taste a wine that I wanted to try again. Scott found one he liked, which we purchased and is sitting in our kitchen, but try as I might, I didn't like any of them. It is hard to describe (clearly I'm not a wine gal), but the best I can say is that they were very strong-flavored, and a little bitey. I prefer much milder tasting wines, generally a little on the sweet side (Wine sushies at Otto's are my favorite!!).
One big difference about wineries in California versus Pennsylvania is that nearly all of the grapes used are local to the area (which I like). But, that means less variety in any given area, and so if you don't like the wines at one location, you probably will not like the wines at the surrounding wineries. Still, the town of Livermore itself is beautiful. It is very clean with lots of quaint little shops and eateries. I would be very happy to go back and spend a lovely day strolling around there.
