Quotation from: Manners, Custom and Dress During the Middle Ages and During the Renaissance Period

Written by: Paul Lacroix

After a great famine, Domitian ordered all the vines in Gaul to be
uprooted so as to make room for corn. This rigorous measure must have
caused beer to become even more general, and, although two centuries later
Probus allowed vines to be replanted, the use of beverages made from grain
became an established custom; but in time, whilst the people still only
drank _cervoise_, those who were able to afford it bought wine and drank
it alternately with beer.
