Raise mash water to strike temperature.
Add the crushed grain.
Mash at...
62°C for 18 minutes
64°C for 8 minutes
72°C for 30 minutes
77°C for 10 minutes
Then boil for 30 minutes
The gravity of the wort should be ~1.039
Leave pot to cool.
Transfer to fermentation vessel and top up to 10 litres if needed.
Cool fermentation vessel to 10 C.
Sprinkle yeast directly into fermenter.
Bring pressure to 12 PSI.
Allow 1 day for yeast to begin.
Increase temperature to 20 C.
Once fermentation is within 2 to 5 points of its terminal gravity (1.019) leave for diacetyl rest for 3 days.
Cold crash to 0.5 C for 3 days applying pressure to hold at 12 PSI.
