More importantly, like infusing a wooden keg with brett or other bugs, the porosity may be exactly what you are after. I am working with a 55 gallon wooden cask right now, infusing it with bugs so that the porosity of the wood hold the wildness I want it to impart. Fun stuff.

I wonder if the clay they use is tested for heavy metals etc.. I'm thinking Rome and lead.
