We needed something to ferment in that can maintain the mash temperature for fermenting. We needed to hold a temperature of 18°C to 24°C, so we set the controller at 21°C +/- 2.5°C.
We set the chiller to its maximum cooling temperature (-3°C) and the heaters to their maximum (32°C).
When the temperature reaches 23.5°C the chiller and the pump will turn on, until the temperature is 21°C, and when the temperature reaches 18.5°C, the heaters will turn on until the temperature is 21°C.
To fill our barrel we calculated that
175 Litres @ 15% ABV will distill to 26.25 Litres @100% Alcohol
175 Litres @ 20% ABV will distill to 35 Litres @100% Alcohol
So we picked a 220L plastic barrel for the mash.
