Amphora and qvevri wine
Clay instead of oak or steel, and eight thousand years of it.
Clay was the first winemaking vessel and it never fully went away. In Georgia the buried qvevri has an unbroken eight thousand year run, in Spain the tinaja survived in La Mancha, and in Italy the amphora came back through Friuli in the nineteen nineties.
Clay is porous, so the wine breathes slowly the way it does in oak, but the vessel adds no flavour of its own. No vanilla, no toast, no coconut. What you taste is fruit, ferment and texture, which is exactly why low intervention producers reach for it.
Buried qvevri also holds its own temperature through fermentation without any intervention at all, which is the point.
Questions
What does amphora ageing do to wine?
Clay is porous, so it allows a slow oxygen exchange similar to a barrel, which softens tannin and builds texture. Unlike oak it contributes no flavour compounds of its own, so there is no vanilla, toast or spice. The result tends to taste more directly of the fruit and the ferment.
What is a qvevri?
A qvevri is a large egg shaped clay vessel buried to the neck in the ground, used in Georgia for around eight thousand years and recognised by UNESCO. The earth around it holds a steady temperature through fermentation without any equipment at all.
