Preparation for brewing No. 9

No. 9 will be a variation of the recipe for Adnams Bitter in Brew Your Own British Real Ale by Graham Wheeler and Roger Protz (CAMRA/Storey ISBN 1-58017-102-8). As usual I'll brew 30 litres, the recipe below is scaled up from the 25l version in the book. For the malt I've substituted pale malt for the Maris Otter because that's what I could find.

Black malt 60g 1200EBC

Boiling Hops
Start of boil:
Challenger 39g

Last fifteen minutes:

Method:

Heat 20l water in boiler to 77C.
Add grains and hold at 66C for 90 minutes or when iodine test shows conversion complete.

Remove grains from boiler to another barrel with tap.
Heat another 10l water in boiler to 77C and sparge grains.
