Ultimatum #2

12/19: Mash temp lower than aiming for as well as sparge temp, crush not as good, all of which may have brought down efficiency from estimated 68%. Or, because of higher grain bill had to mash at 1.25 qts/lbs instead of 1.5.
Cold-steeped chocolate and black malts overnight.
Initially collected 4.75 gallons of runnings (5.75 gallons in mash/sparge), so grain absorption not as much as estimated but after an hour another 3 cups drained out (all lead me to think that crush was inadequate).
Boil off with two pots was .5 gallons/hour, as estimated.
O2 for 60 seconds, pitched starter of 2124 at 61 and brought downstairs to ferment (low 50s). Noticeable activity within 6-7 hours.
1/2: Fermented for 5 days at 50 to 52, brought up to lower 60s, then finished at mid 60s.
Racked to secondary with about 1oz of medium & medium plus oak cubes soaked in rum for 14 days. Left to lager on porch, temperature varying between low to upper 30s
6/27: bottled to estimated 2.2 vol/CO2
