Malting (1) Malting (1)
The malting process begins as the barley is soaked in water for two-three The malting process begins as the barley is soaked in water for two-three days in steep tanks. The soaking increases the moisture content of the days in steep tanks. The soaking increases the moisture content of the grains which in turn triggers the germination process. The barley is then grains which in turn triggers the germination process. The barley is then moved to a malting facility (e.g. a malting floor or a drum malting) where moved to a malting facility (e.g. a malting floor or a drum malting) where the germination continues. The purpose of the malting is to convert the the germination continues. The purpose of the malting is to convert the
starch in the grains into fermentable sugars which will feed the yeast during starch in the grains into fermentable sugars which will feed the yeast during the fermentation stage. Heat is produced during the germination so it is
