I was reading your article on wines in the Czech Republic and didn't see anything about Burcak, a young Moravian wine. I read about it in The God Complex, a new thriller novel set in Prague.
I visited Prague last fall and took the book and printed off a free self-guided tour from the book's website. I learned more interesting things about Prague from that book than the guided tour I paid for there. Things such as Burcak, where to find it, and that it's only served in the fall. Luckily, it was fall when I visited. I also found the pig's knee restaurant described in the book. The book had enough history/background of the sites listed in the tour to make it a good compliment/replacement for a local tour. Just as the tour says, it will turn your trip into an adventure. It's definitely worth packing for a weekend trip.
