I forgot you had the English bitter kit,didn't go back & re-read the whole thing. But as I said,the German hops will taste good,that smooth spicy thing they have always seems to work well. Perle & Saaz are another good combo.
I got an OG of 1.038 on my EB,with 1 box of Cooper's plain light DME,.5kg I think. You'll like it if you like browns & such. I love this one with pit bbq,even as a base for moppin sauce. You gotta try that! Good session beer for beef/ribs sort of pit bbq. I'm gunna make more for warm weather just for that purpose. I was told that 2 boxes of the Cooper's plain light DME & an ounce of EKG makes a nice Fuller's clone. And I have the Cooper's micro brew FV kit. It's the one sold before the DIY version you have. Both great FV's I think. The new one has the loose lid & krausen collar to do the same job. The co2 escapes from the lid. They also come with clamps for the lid,I guess for clamping the lid down after initial fermentation is done,& not much co2 will be escaping.
