It was a decorative barrel near their tasting room and stood on end.
I was thinking of drilling a good-sized hole in the top and putting a super on it and then a big roof on the super. to keep rain out of the barrel. I have lots of supers, but have run out of deeps after collecting swarms this spring.
What if all that room were to slowly disappear? You could fill it up with water slowly to drive them out, or something like sand. Maybe fill it to the bottom of the comb through a new hole, and then add a few pounds a week until the queen moved up into the new box you laid out for her.
Another option would be to carefully disassemble the barrel and then do a cut out. The end should stay intact when the side bars are removed. You may even be able to remove a few at a time until it is half gone if you leave one or two for support.
I'd sell the honey for a premium. Like drunken goat cheese it has been aged on wine.
