It seems like Master is the upper end beer from Pilsner Urquell.
This is another beer that looks like it should taste differently. This looks and pours and had a head just like a porter. It has a very rich taste, just nothing like what you would expect. You get a little of the roasted taste with a lot of different sweet flavors. The increased alcohol content in obvious in the taste and effect. Glad I am less than a block from my hotel, I would hate to get lost in a foreign country.
