'Grzane Piwo'That’s hot beer in local layman’s terms – essentially a frothing hot pint of lager (typically Tyskie or Żywiec) spiced with artificial ginger or raspberry syrup ('imbirowy' or 'malinowy,' respectively - the choice is yours), clove, cinnamon and other mulling spices. For some it's an acquired taste, for others an early Christmas present and others still an utter profanity, but grzane piwo is an invention everyone should try at least once.
There are a few things to consider with regards to hot beer. First is the type of syrup you want, as you will be asked: 'imbirowy' (ginger) or 'malinowy' (raspberry). This choice seems to be almost universally made along gender lines, with the fact that taking raspberry syrup results in a pint of pink beer almost certainly playing a factor.
Secondly, it takes a while (5-10 minutes) to properly heat the drink without exploding it, so prepare to wait and be patient.
Lastly, and this is important: there is a tendency to immediately stab a straw into the glass to mix the syrup at the bottom throughout the drink and start drinking. If the beverage is too hot, however, this will result in it erupting all over you. This common rookie mistake is an event many twisted bartenders wait for with relish; you can avoid it by simply letting your drink cool slightly and gingerly testing its reaction to the straw. Don't take this advice lightly; you really don't want beer foam all over your lap.
