The four main ingredients used in beer production are malt, water, hops and yeast.


  • The main grains used to make beer are barley and wheat, Linnasedbut rye, rice, corn et al. may also be used.
  • The advantage of barley is the hull of the grain(around the kernel) that is low in protein, but rich in starch.
  • Mainly malted grains are used for beer production.
  • Barley is germinated, cleaned and dried in the course of malting.

  • parmLager or cold / bottom-fermenting yeast – works at temperatures from 7-12 °C.
  • Ale or warm / top-fermenting yeast – works at temperatures from 15-25 °C.
