Notes

efficiency down - did 3 liters too much - pre-boil gravity was 1.081 - target was meant to be 1.90. This is due to no sparge method and initial calculation of efficiency not low enough, will lower 10% next time to 55%

boiled for 130 minutes

at end of boil added 500 grams light DME.

ended with 1.105 gravity
