Brew Day: Yarmouth Special Dark Bitter

After a visit to The Blue Anchor in Delray Beach, FL, and a few pints of London Pride, I decided I must have an English pale ale/bitter style beer at home.  This recipe is essentially the Pride formula with the addition of a touch of Thomas Fawcett pale chocolate malt (200L), and a simpler hop bill (excluded Challenger, bumped up EKG's). After much success with Wyeast 1469 - West Yorkshire Ale yeast it is always at the top of my list. The result is a browner, stronger (unintentionally, the wind boosted the evaporation rate),beer that hopefully captures the same spirit as a pint of Pride.

6 gallons 

70% efficiency (planned)

SG: Pre-boil 1.048 - 7 gallons (1.044 planned)

IBU: 33 Rager Formula

SRM: 11

Grist

12 lbs Marris Otter Pale Malt

0.5 lbs Simpson's Dark Crystal 70L

  3 oz  Fawcett Pale Chocolate  200L

Mashed with 4.5 gallons of 165F strike water @ 155F. Stepped up to 162F with 1.5 gallons of boiling water.

1.5 tsp of Gypsum to mash

1.5 tsp of CaCl to mash

0.5 tsp of Gypsum to boil

Sparged with 3 gallons of water at 175F.

Hops 

75 mins - 1.0 oz East Kent Goldings - 5.1 % alpha acid 

15 mins - 0.5 oz East Kent Goldings - 5.1 % alpha acid

15 mins - 1.0 oz UK Northdown - 6% alpha acid

Added 0.5 oz of East Kent Goldings  to the whirlpool after wort chilled below 100F to simulate using a hop back. 

Yeast

Wyeast 1469 West Yorkshire Ale - 1 smack pack at 50% viability ~50B cells. Pitched at 64

Fermentis US-05 American Ale Yeast - 10 g - or ~150B cells. Pitched at 64 2 hours after liquid yeast.

(rehydrated according to Zainascheff and White's procedures)

Oxygenation - filled headspace with O2 and shook for 1 minute. Two doses.

Notes: Must have ended up with around 5.5 or less gallons post boil. The wind was ripping and increased to evaporation rate. Slightly increased efficiency. Collected 7 gallons of wort at 1.048 pre-boil.
