Codename : Westfort Oatmeal Stouthorpe

Doing basic oatmeal stout, but used a bit of a helter-skelter of speciality malts to use up old stock. Trying something out of the ordinary, instead of doing a usual 60 minute boil, brought it down to 30 minutes. I think I nailed it.

Ingredients

  • 1 lbs 10 oz Maris Otter malt (3.8L)
  • 3 oz Oatmeal
  • 2 oz Roasted barley (488L)
  • 1 oz Amber malt (38L)
  • 1 oz Black malt (450L)
  • 1 oz Caramel malt (120L)
  • 1 oz Torrified wheat (2.5L)
  • 0.20 oz Cascade hops at 30 minutes
  • 0.20 oz East Kent Golding hops at 15 minutes
  • ¼ tsp Irish Moss (optional) at 15 minutes
  • 0.20 oz East Kent Golding hops at 10 minutes
  • 0.20 oz East Kent Golding hops at 5 minutes
  • 0.20 oz Fuggle hops at 0 minutes
  • 3 ml Nottingham dry ale yeast

Brew Day

  •  Prepare 6.5L strike water, 159F. 
  • Add the milled grains to the bag. 
  • Place the bag in the hot water, set the timer for 75 minutes, and maintain the temperature at 152 F.
  • Stir occasionally.
  • Calibrate the sonic screwdriver.
  • Lift the bag out of the water, and allow it to drip into the pot. Every bit of sugar that can be extracted will benefit the end ABV.
  • Bring up to a boil, 212F, set the timer for 30 minutes. Add hops and Irish Moss as prescribed above.
  • Sanitise everything required for fermentation.
  • Cool to room temp, an ice-bath or a snowbank work effectively.
  • Prepare yeast mixture.
  • Pitch yeast to the carboy
  • Transfer wort to the carboy.
  • Store in a cool place for primary fermentation for 7-14 days.

Bottling Day

Brew Notes

  • Pre-boil gravity was 1.045, post boil gravity 1.061, much higher than expected.
  • Added 400 ml (100 ml at a time, with measurements in between) to bring it to 1.053. This still gives an anticipated 5.1% ABV.
  • The fact two batches in a row 400 ml has been added give me a clue to increase my start water.
