Use in conjunction with the Grainfather Connect Control Box thermometer, for accurate control of your wort transfer temperature through the Grainfather Counter Flow Chiller.

Avoid long lag time and off flavours by using the Grainfather Wortometer. Adjust your wort and water flow rates from the Grainfather Counter Flow Chiller by dialling in the exact wort temperature your specific yeast requires.

The Grainfather counterflow chiller is used after boiling the wort to cool it down fermentation temperature. The counterflow does this by acting as a heat exchange between the wort and water from your tap as you transfer the wort from your boil kettle to your fermenter. Because this is a one-step process of transferring and cooling, it is more efficient and more sanitary than immersion chillers, and the curved design allows for similar performance to plate chillers without the crevasses that can make cleaning painful. 

The bag is made from robust and tough, nylon material that will keep the Grainfather free from dust, contaminants and exterior moisture and is perfect for transporting your Grainfather.

Simply place the bag on the floor, place the base of the Grainfather inside of the bag and roll the bag up over the Grainfather. The excess material rolls and then clips together for a tight seal, keeping the Grainfather clean and safe until your next brew.
