I now know that an oenophile is one who enjoys or loves wines. It can be any person with a fondness or appreciation for wines. One would probably say they are a connoisseur of wine.
www.dictionary.com defines connoisseur as:
a person who is especially competent to pass critical judgments in an art, particularly one of the fine arts, or in matters of taste.
The word first appeared around 1925 to 1930. It’s origins are from the Greek word oinos which means wine.
