Peat

Translation: торф
Reason: To know what's written on the bottle you drink from:)

Also: Peated malt* - "distillers malt that has been smoked over burning peat in order to add a dark aroma and flavor characteristic of Islay whisky and some Irish whiskey. Some recent brewers have also included peated malt in interpretations of Scotch ales <...>. When used in large amounts, the resulting beer tends to have a very strong earthy and smoky flavour which most mainstream beer drinkers would find repulsive" (from here).

*malt - солод
