I'm going to do a couple of single tin kits, EDME Irish Stout and Coopers Bitter. I have stacks of brewing sugar and a Thomas Coopers tin (1.5kg) of dark malt extract (which can be used for the stout?), and another coopers tin of light malt extract (which could be used for the Bitter?). Both kits reccommend 1kg of Sugar with each, what qauntity of Sugar/Malt extract would be recommended? Also can this Malt extract be used?
