Pitched 5-hour 50g/500ml starter from saved yeast
Racked on top of 1.4kg frozen cranberries, boiled
3:45 from unpacking gear to starting chilling
6 hours from unpacked to cleaned up
No activity after 24 hours. Pitched a second vial of washed yeast without a starter.
Bubbling started 12 hours later, strong bubbles for 3 days.
Bottled on 2018-10-24 (8 days):
TONS of yeast trub. 7L. over 1/4th of the bucket.
21L in the bottling bucket
Assumed 25L, so primed with 130g sugar. Too much, too much.
FG too high, too. Possibly raised a strain of bad yeast, since Thermal Fuse was too high also.
FG: 1.022 (hydro, unadjusted) / 1.020 (hydro, adjusted)
FG: 7.8 °P (refract)
