The barrels from the mod Storage Overhaul don't work for the recipe used for the brewing barrels. Could you add them in as part of the recipe?

I took a quick peek just now since I was over here and it looks like it would be a major pain, since Storage Overhaul didn't add their barrels to the forge tag for barrels.

I would recommend changing the brewing barrel recipe here to use "tag": "#forge:barrels/wooden" instead of "item": "minecraft:barrel" but from there it'd be up to the Storage Overhaul devs.
