> Gradual permeation of gas through the clay barrier allows oxygen to enter the container, keeping the grapes alive, while the elevated concentration of carbon dioxide inside the package inhibits the grapes' metabolism and prevents the growth of fungus. The grapes are prevented from drying out, and the mud absorbs liquid which would otherwise lead to bacterial and fungal growth.
Pretty incredible that this works. I wonder how much trial and error went into perfecting the process nearly a millennium ago.
Can we please use titles? e.g:
>Kangina: desert method for grape storage
As an amateur chemist/nerd, this definitely is an interesting article (fits HN theme, just needs a better descriptor).
It's crazy that this is such a delicate process, and yet someone discovered that it works. Amazing.
Well, I'm not sure what I was expecting, but it wasn't that.
> The containers are, however, heavy, unwieldy, and prone to absorbing moisture.
Sounds like they'd only really make sense for surviving in dry environments. But still quite neat!

Has anyone found them in Europe? I'd like to try how they taste
An awful lot like grapes, I'd imagine.
I think you'd find the clay a bit dry for a refined palate.
