Without sugar there would be no alcohol! Sugar is fermented by the yeast to produce alcohol and carbon dioxide. Many beer, cider and wine kits/recipes will call for sugar to be added at both the primary and secondary fermentation stages and you will find many types below. The standard choice is our Brewing Sugar (Dextrose Monohydrate) which we sell in 1kg bags. At just £1.80 per kg this is as cheap as you will find anywhere.
