Quass, or Kvas, a word signifying sour, an ancient Scythian beverage, is the ordinary household beer of Russia. A variety of it called Kisslyschtschy is variably described as exceedingly pleasant, and as an abominable small beer, something like sweet wort or treacle beer, almost as vile as the Vodki or Russian gin. These matters of course depend on individual taste. The Russian pivo, also in common use, is said to resemble German beer, but German beers are many and diverse.
