I’m moving this back into the brewery to bring the temperature up a notch, seeing as I probably misinterpreted the instructions and stored her a little too cool. Ambient temperature in the office was 19.1 ℃ (vessel measured at 20.4 ℃ using infrared thermometer) when I moved her out at 21:45 tonight.

Next morning

Brewery ambient temperature is 21.9 ℃ and the vessel is starting to acclimatise, currently at 21.6 ℃ as per infrared thermometer. No change in rate of bubbling but I expect that to increase slightly for the last remaining couple of days as the temperature climbs in the brew.
