As to the vineyards, the vintage should begin when the grapes are ripe; and you must choose the variety of grapes and the part of the vineyard with which to begin. For the early grapes, and the hybrids the so-called black, ripen much earlier and so must be gathered sooner; and the part of the plantation and the vineyard which is sunnier should have its vines stripped first. At the vintage the careful farmer not only gathers but selects his grapes; he gathers for drinking and selects for eating.. So those gathered are carried to the wine-yard, thence to go into the empty jar; those selected are carried to a separate bucket, to be placed thence in small pots and thrust into jars filled with wine dregs, while others are plunged into the pond in a jar sealed with pitch, and still others go up to their place in the larder. When the grapes have been trodden, the stalks and skins should be placed under the press, so that whatever must remains in them may be pressed out into the same vat. When the flow ceases under the press, some people trim around the edges of the mass and press again; this second pressing is called circumsicium, and the juice is kept separate because it tastes of the knife. The pressed grape-skins are turned into jars and water is added; this liquid is called lora, from the fact that the skins are washed (lota), and it is issued to the laborers in the winter instead of wine.
Written by Roman Marcus Terentius Varro in his 80th (approximately 37 B. C.) year for his wife, Fundania, who had just purchased a farm. It is intended as a practical manual of husbandry. His work is usally coupled with de Agri Cultura written by Cato the Elder. At present the whole of the Napa Valley smells of wine as the harvest is on.
