Is anyone else using the Gigawort for BIAB small batches? I have made six batches so far. I use a wire 9 inch cooling rack in the bottom to keep the bag from touching the bottom. The temperature control has a 6 degree deadband, but I have found that the mash temperature holds within about one degree. I brew a 3 gallon boil after pulling the grain bag. I am curious if anyone else has used this. This has cut about an hour off my brew times since switching from propane.
