I've tried several times to find a Clone Recipe of Greene King Abbot Ale, but none of the editions of Graham Wheeler's "Brew Your Own British Real Ale" have a version and the one listed in Dave Line's "Brewing Beers Like Those You Buy" contains ingredients that don't correspond with those on Greene King's own website.
On the labels on Abbot bottles, Greene King admit to using Pale Malt, Amber Malt and Crystal Malt and on their website they say that First Gold, Challenger and Fuggles as their hops.
With this in mind, and making use of Graham Wheeler's "Beer Engine", I combined the ingredients to try and obtain a beer which had a starting gravity of 1049°, an EBC of 14 (decided on by holding a bottle up to the light and comparing it (from memory) to my colour charts) and an EBU bitterness of around 28 (decided on because I don't really like over bitter beers).
My recipe came out as:
|Maris Otter Pale Malt||5||4750g|
|Whole First Gold||8.3%||15g||90 mins|
|Whole Challenger||7.6%||15g||90 mins|
|Whole Fuggles||3.9%||10g||15 mins|
On subsequent brews, I added 7g each of First Gold and Challenger hops as late boil additions for the last 15 minutes and they really enhanced the flavour without really changing the bitterness.
