Hi - I have a Williamswarn 10l kegging system. If I use a 23l kit and split it between 2 10l kegs for fermenting will I need to purchase another lot of yeast, also the kits takes 1kg of dextrose, do I just halve it and what do you think it will do to the taste? I also assume it will increase the alcohol. The kit I am looking at using is the Coopers Real Ale which I assume will be around 4%. Any assistance would be appreciated.
