Oenology (enology; ee-NOL-o-jee) is the science and study of wine and winemaking; distinct from viticulture, the agricultural endeavours of vine-growing and of grape-harvesting. The English word oenology derives from the word oinos, "wine" (οἶνος) and the suffix –logia "study of" (-λογία) from the Ancient Greek language. An oenologist is an expert in the fields comprehended by the "Viticulture and Oenology" designation for oenology-training programmes and research centres that include schooling, training, and education in the outdoor and indoors aspects of wine and the making of wine.
Wine (from Latin vinum) is an alcoholic beverage made from grapes, generally Vitis vinifera, fermented without the addition of sugars, acids, enzymes, water, or other nutrients.
