Referencing Merriam-Webster online, once again, the definition of OENOPHILE is:
: a lover or connoisseur of wine
This is very easy to use in a sentence:
I am an oenophile.
In fact, right this minute I am sipping a 2006 Acacia Carneros Chardonnay. (The link for the wine is the lowest priced ($13.95) place to buy this wine that I found on the internet, or even in the stores–which range from $15.99 to $21.99.)
