Been on the coopers web site forum and a guy from coopers recommends this recipe:-
Wondering if any has ever tried this?Best Extra Stout
1.7kg Coopers Original Series Stout
1.7kg Coopers Original Series Dark Ale
1kg Dextrose
Made to 23 litres
Both sachets of yeast (re-activated Coopers yeast culture)
