I've been using Paines Maris Otter Light Malt Extract (49.99 for 25kg) which I've found to be very good and pretty cheap. Looks like it's going to be unavailabe soon
Thanks DaaB- I'll look out for them, I'll not need any for a while got a 25kg of Paines MO delivered yesterday -but nothing like planning ahead.....might even go AG after the extract runs out........
