Not living at home, so today it was mad dash home to start a beer off for the new year. Single can kit so it was just pour sugar and can into fermenter top up to 40 pints bang it into freezer with an 8 watt bulb to heat if required. In the main the brews end up at around 18 deg C but little low or little high no problem the STC-1000 will either switch on bulb or run freezer and temperature is soon corrected. However as I carried the brew to garage I swirled it about and the temperature probe was recording 10.5 deg C, no time to play with different heaters I had to just shut the freezer door and leave. I reckon on 30 hours to warm up, before the yeast starts to work, so not a clue if the yeast will work before any wild yeasts take over, it was after all just tap water.
