I reduced the IBUs quite a lot.

I reversed the quantities of amber and brown malt from Ron Pattinson's original recipe.

Substituted mild ale malt for Sussex pale malt.

Used continuous re-circulation throughout entire mash.

Mash Gravity: 1040 at 30 min, 1047 at 60 min. Reduced mash temp to 148 at 60 min, and mashed for a further 30 min. Final mash gravity: 1049 using refractometer. Hydrometer 1040 at 107 F = 1048 temp corrected. Hit the post boil gravity right on the noise at 1068. Mash eff 85%. I miss read recipe supposed to have been 1065, oh well what can I do add water? Know way!

Primary fermentation slowed considerable after 4 days. OG using corrected refractometer reading was 1024. FG is estimated at 1020, so will leave one or too more days and move to corny keg for secondary fermentation for as long as it takes. I expect that this should be at 1016 in a year or so:)

Did not tast overly bitter could have perhaps kept to original recipe IBUs of around 160. Will add 1 oz of finishing hops to corny keg in bag. Corrected water profile so would not be too malty 0.9 ratio.
