Bought this on the bus to Valladolid, when a peddler got on during one of the (many) mid-trip stops. It tasted alright, but it really looked suss. By the time I'd drunk about two-thirds of it, I noticed a few mosquitoes floating around at the bottom, and I decided that I'd pushed my luck far enough. Total miracle that this stuff didn't hospitalise me.
Really dodgy drink.
