Craig,
This is a domain name with several issues. Most people dont search for "quality wine". Google is reporting that roughly, 700 people type this exact phrase per month, system wide and my guess would be many of those people are looking for qwine.com (Quality Wine & Spirits) a wine wholesaler. There are also no advertisers for the keyword Quality Wine.
This type of keyword especially attached to .net is going to have no where to go in regards to resale. "Quality" is a funny word, one which in todays english has a subjective meaning. Quality has become so overused, that its almost like saying its slightly better then a regular version. Wine in specific is a luxury product (granted, there are Boxed wines, but those people dont buy them online). In terms of Wine - the proper keyword for a good wine, is "fine".
These reasons make this URL good for pretty much nothing more then a Wine Blogging site - and even then, I would say its not a very desirable one. I believe this particular domain name is valued at the registrations costs - less than $10.
