I LOVE THIS!! Super ambitious! I have an idea for the vessel body that i think would give it structural integrity, would help contain potential contamination, and i think would increase the life-span of your vessel.. if you can find a way to wrap and seal the bottles, perhaps by placing all of the bottles within a light, rigid frame wrapping it tightly with a durable tarp, i suppose you could use adhesive to keep it together, or in a perfect world i imagine vacuum sealing the whole frame of the vessel into one solid piece!!
