Oenology,[p] œnology (BrE), or enology (AmE) is the science and study of all aspects
of wine and winemaking except vine-growing and grape-harvesting, which is a subfield called viticulture. “Viticulture & 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.
The word oenology is derived from the Greek οἶνος - oinos, “wine,” and the suffix -λογία, -logia, "study of."
