Tuesday’s ad is for Pilsner Urquel, because today is “Pilsner Day.” That’s because it was today in 1842 that the Citizen Brewery in Plzen, Bohemia — in what today is the Czech Republic — first brewed Pilsner Urquell, the world’s first pilsner. The ad is fairly recent, but plays on the beer’s heritage as a noble beer, Pilsner I, or Pilsner the First. And it’s just beautiful.
