Tap at the Prague Beer Fest 2023 thanks to an unknown benefactor hahahah. This was actually the most bizarre tick of the day - there I was, minding my own business / working hard when a gentleman in his 50s sidled up to the stand and offered me a sip of his beer, Lončák he says, kyseláč. Tried to communicate with him in broken Czech, but he was slightly struggling to communicate himself, but not due to foreigner who should learn better Czech reasons. Still, I took the offered sip, as the soft red berry / raspberry aroma was pretty clean and fine, and my sip or two revealed a clean, well-made, lightly tart raspberry-driven taste. The gentleman, on the other hand, used the moment to grab something like 10 of our coasters in return. I put the beer back, he took it and on his merry way he went, having traded I guess, some of his beer for coasters he could've just taken without anyone making a fuss (at our stall at least). Still, I was glad to have tried a very much well made fruit sour from a brewery I hadn't had that many fantastic experiences with a year or two ago! Props to Lončák for improving too!
