There were vineyards in a lot more places than today. Perhaps warmer?

But phylloxera a vine disease wiped out vineyards in a great many places in the 1800s. South Australia is the only place on Earth where phylloxera never arrived. As a result the Barossa has the oldest vineyards on Earth. Two or three claim to be oldest, 1850s.

Phylloxera resistant root stock is used in modern vineyards with quality varieties grafted to the root stocks. Most of my vines are own roots. Which produce better quality grapes and wines. Mine would die if phylloxera got past quarantine restrictions.
