Oenology

Wine grape diagram

Oenology,œnology, or enology is the science and study of all aspects of wine and wine-making except vine-growing and grape-harvesting, which is a subfield called viticulture. “Viticulture and oenology” is a common designation for training programmes and research centres that include both the “outdoors” and “indoors” aspects of wine production. An expert in the field of oenology is known as an oenologist.
