Just brewed my first ale at the weekend, Nelsons Revenge, which i did exactly as per the instructions on the box (as well as Daabs guide on here

Once this is kegged (all being well) I have a John Bull Executive Bitter kit to do. I was just wondering if there are any tweaks or additions you would recommend which would improve the final product. It is a 3KG kit which does not require the addition of any sugar, so Im not sure whether Im limited in this respect.
Cheers
