It Helps Review by Michael
The Grainfather Graincoat helped maintain temps during the brew day. However, I was still not able to reach 212* F. I do believe the Graincoat helped maintain the temp at 209* as the temp did not fluctuate below that temp. I would recommend this item for the Grainfather, especially if you are brewing in cooler regions. (Posted on 3/24/2018)
