What a great find. I'd be interested to know what their infused wines tasted like. How much have our pallets evolved? Are we currently making similar types of wines? I recall reading about some honey that was discovered in an ancient tomb and is still edible. I doubt any of the casks still have anything in them and if they did the wine would certainly have turned, but it would be cool to say you've tried a wine made in 1700bc. -those were some great vintages.
It mentions the in Greece, there are some kinds of wines infused with tree resins that are still commercially made, though it doesn't comment on the quality. I'd be really interested to try some of those out too. The article also mentions that while no liquid remains, there is residue that gives clues about what the wines were flavored with. I hear that the Hellenistic Greeks in particular were fond of adding various herbs to their wines to produce different buzzes, so who knows if those wines (if reproduced) would even be legal.
I am surprised that this find is the oldest at 1,700 BC. Winemaking goes back a lot further. In my limited travels, we were in Umbria, Italy where there are Etruscan founded settlements like Orvieto with underground caves where all sorts of goods, including wine were stored. Those sites are known to be 2,500-3,000 years old so I would think there would be older sites elsewhere.
