To be clear: the bucket from Midwest Supply DID have a small grommet in the lid where my airlock fit snugly. The lid itself did not have a large red rubber grommet encircling the entire outer edge of the lid. After reading these answers (thanks) I believe there is no way to seal this bucket lid...
Hi there,
I just started an IPA beer in the 6.5 gallon fermenting bucket from Midwest Supply (it does not have a rubber grommet in the lid). I placed an airlock, and firmly placed the lid all the way on with light taps from a hammer.
OG was 1.064. Constant temp in brewing area is 78 degrees...
