We have the Finger Lakes region wineries, the Chautauqua region wineries; we travel and there are often wineries where we go to. Makes for a good time killer. Prices range from free, to $10 (includes keeping the glass) for trying somewhere between 4 and 10 different types of wine. Last place we tried wine, we each tried 6 flavors, and took a tiny sip of each others' when we thought one was particularly good. We'll generally get between 2 and 12 bottles of wine at a winery following a wine tasting. One bottle (750ml) is perfect for 1/2 an hour in the hot tub on a cold fall/winter evening for 2 people. That's about 2 glasses each. I prefer to not have leftover wine, since the oxygen quickly degrades wine. Though, some wines are temporarily enhanced by the infusion of oxygen - in particular, a wine I tasted at New Hope winery (somewhere near the NJ/PA border) had some buttery hints that weren't present prior to having a bit of air added.
I don't understand why people like those wine clubs, unless they live in a region void of any wineries. A winery might have 30 different wines that they produce - and they manage to sell all of those types of wines. Thus, someone likes the styles that I don't like. Why would I want someone to pick out full bottles of wine for me that I might not enjoy? I've had sweet wines that I love, sweet wines that I hate. My wife seems to prefer semi-sweet to sweet, and ditto - plenty of them that she doesn't like. And, there are plenty of dry wines that she does like. Plus, I make my own wine at home; generally non-grape, fruit wines, though this fall I'll probably do 5 gallons each of concord & niagara. (25 bottles of each)
