This is the fermentation tank at U Medvidku. Note that it's wooden and open.

On the path up to the castle, there was a small cafe selling roast pork, as usual, but because it was September they also had Burcak. This is partially fermented wine, still in the process of being fermented. It's sold in the cheapest plastic bottles that I've ever seen, and in plastic cups, perhaps to discourage people from storing it. In reality, although Burcak is sometimes rated for a three day shelf life while refrigerated, my experience is that it's closer to 24 hours. Once it's out of the winery, it goes bad very, very fast, which makes it all the more of a treat given that it's only available a few days out of the year.

This is one of the fermentation vats at the Novomestsky Pivovar, a brewpub on Vodickova in Prague. Most of the brewpub is located underground in medieval cellars thought to have long been connected to brewing, although the current business only dates to 1993. These vats are unusual for places like this in that they're fully modern, as in stainless steel, while most brewpubs pride themselves on using very old fashioned methods in order to improve quality. To be fair, though, these vats are open, which is old fashioned, although they're protected behind glass.
