Cassiodorus

“I have a wine to describe the singular mode of manufacturing this wine. The grape cluster, gathered in the autumn, is hung up under the roof of the house to dry till December. Thus exuding its insipid humours it becomes much sweeter. Then in December, when everything is bound by the frost of winter, the chilly blood of these grapes is allowed to flow forth. It seems to shed tears of joy, and delights the eye by its beauty as much as the palate by its flavour.”
Letter from Cassiodorus (c485-c585).
