Hi guys, just joined and am saying hello. Just started my first brew, a wilkos kit of lager 4.3%. I have just put the first lot into bottles for the second part of fermentation (I think) used cider two litre bottles (are these ok ?) I am going to the local home brew shop tomorrow to get the next bash on the go but want something a bit stonger, about 6% or more. If I go the pub I like to drink stella or kroenenberg or the like. Can anyone give me some advice on making the lager kit stronger ? Many thanks.
