This is a great, interesting example. From the Wikipedia page on Phylloxera:

> In France alone, total wine production fell from 84.5 million hectolitres in 1875 to only 23.4 million hectolitres in 1889. Some estimates hold that between two-thirds and nine-tenths of all European vineyards were destroyed.

Little known fact: we lost the grape used to produce mustard before Phylloxera.

[hn_throwaway_99]

Can you explain? I don't understand, as mustard is made from the mustard plant, not grapes.

[sam_lowry_]

Mustard grains are soaked in wine vinegar nowadays.

Before phylloxera, a grape that gives a wine with high acidity was used.

It went extinct.

correction: mustard flour, not grains.
