50g @ day 6 DH]
First use of ‘fermentation chamber’ – stand-up freezer and a fermenter heat-band.
First use of Pill in the fermenter for gravity and temperature, and temp controller with probe tucked into string of heat-band sitting against the middle of the fermenter. Setting 18C +-1C, with max5C differential between pill and probe, 2min compressor cooldown. Increase to 20C for post fermentation rest.
pill calibration was factory, the portal would close as soon as I unplugged the charge cable (which should activate it for ten minutes) so i wasn’t able to calibrate it. however in water it read 0.995, so factory calibration was likely close enough to be usable. [EDIT: I didn’t fully charge the battery so the pill battery calibration was not set/complete. Once fully charged (and on the portal calibration screen) it stayed open for 10min]
OG with the pill showed 1.057.
Using the hydrometer I read 1.061.
Pressure kit needed a bit of a flush.
Dry hop – day 4 (19/09/2023) 100g Riwaka. Pill reading about 1.014.
Adjusted spunding valve after dry hop, then checked on pressure after a couple of hours – it had increased to 10PSI.
Purged down to 5PSI in bursts to prevent foam hitting the top, adjusted valve until it was bubbling away on 5PSI.
Held at 18C and 4 or 5 PSI until day 6. Pill read 1.010 for 24hours.
Target temp raised from 18C to 20C.
day 13 (pm) decrease target temp from 20C to 12C
moved to bench to settle for botttling day 14 am
