Notes

BIAB.
Marris Otter, flaked oats and flaked barley mashed for 60 mins.
Chocolate malt and roasted barley added 15 mins before end of mash.

Strike water - 7 gallons.
Grain bag sparged with 1 gallon, and then added back to the boil.

Brew day was straight-forward. Efficiency lower than expected, a little disappointed with 1.044. next time, mash for longer

More notes as this progresses.
