"The recipes found in the Wagstaff
Miscellany are not recipes for making wine but rather recipes for rectifying
wine that has somehow gone wrong, either in its color or in its flavor. The
response of the modern reader to the very idea of recipes such as these is
usually one of disgust. How could people do that to their wine? And how
could they bring themselves to drink the wine after they had adulterated it?
But it bears asking whether these remedies are really repulsive."
