For sure... we use this at the winery where i work, unfortunately i think the stem is too tall to use it in a half barrel. I am leaning towards steaming for the reasons you mention.The equipment to do this is NOT cheap though to do it properly. Collectively we have over 25k wrapped up in barrel steamer, wash head, and pressure washing pump. There is not way around that. I’ve tried. You must invest if you have a good deal of money wrapped up in oak. If you are just a hobbiest your best bet is a hot water wash and sulfur sticks.
