I'm also after a good dark lager recipe. Been thinking Thomas Coopers heritage lager, tin of dark liquid malt extract and S189. Maybe half a kilo of brown sugar as well. Be keen to see some more ideas though
I would definitely use the Morgans Ironbark Dark kit as a base. I made a few of them early on as-is and found them to be very bland in the hops department - would be a good base to add some Euro hops and use a lager yeast.
