1.25L starter. Pitch at 64F, keep cool for a couple of days then allow to ramp up on its own.
7 hour boil!
No water additions except lactic acid and Campden tablet - the minerals in the water will concentrate over the 7-hour boil, so I don't want to add anything extra.
Mash with 6 gallons, then boil for an hour before topping up with 1-2 gallons of separately boiled, filtered water to replace the boil-off. Keeping the overall boil volume lower should help to use less propane, and might increase the rate at which the wort changes.
Need to make sure that:
1) the volume never gets too low and allows the wort to scorch
2) the final volume is reasonably close to the target
3) the propane doesn't run out before the boil is done
