How do I stop air getting sucked back into the airlock when I crash cool the Conical Fermenter?
Before crash cooling, the Pressure Transfer Kit can apply 0.5psi of CO2 that can be added to the top of the fermenter by adjusting the needle valve.
This adds a blanket of CO2 to the top of the fermenter and stops air getting into the fermenter as the beer contracts as it rapidly cools.
Cooling slowly 3°C (37.4°F) per day will allow equilibrium between the pressure in the fermenter and the outside pressure. This slow cooling will stop air getting back into the fermenter as the temperature drops.
