re: On average, how much do you spend on a bottle of wine?

Depends on the host and event

My wife’s weeknight girl stuff, a 18 dollar of rose or two we buy by the case

Normal casual dinner gathering, some 35 dollar crowd pleaser type

I’m going to a wine dinner with some more semi-serious wine people this weekend, so 50-75.

I rarely buy wine specifically for an event, though, it’s all from whatever we have on hand
