Excellent quality bag and it fits my 20 gallon SS Brew Tech kettle. The kettle itself is around 22 gallons in size and the bag fits perfectly. It's snug at the top and the seams are sewed in to the tabs which wrap around the bag. This bag would be perfect for pots from 18.5 to 22 gallons no problem. 4 tabs make it easy to hoist from the pot.
