Mashing & Fermentation
![]() |
After the malting process the barley is milled and added with hot Irish water to a mash tun where the starches in the mash are converted to sugars and the resultant liquid is called 'wort'. Yeast is added to the wort and fermentation begins. The living yeast feeds on sugars, producing ethanol and other alcohols. Large volumes of carbon dioxide gas are also produced and the wash froths violently.
