Yonny from Copper Kettle Home Brewing shows how beer can be brewed from natural ingredients; just using water, malt, hops and yeast. He gives some useful tips, explains the processes and equipment he made himself, and a little bit of the chemistry to help new brewers get it right. He opens up a world of different recipes, tastes and flavours. The recipe he uses can be found at http://www.copperkettlehomebrewing.co.uk
