The straightforward one: a well-priced group tour through several of the Verde Valley's vineyards and wineries with a local host, transport handled, and none of the luxury markup. If your goal is maximum wineries per dollar — and a driver, obviously — this is the efficient choice.
The Verde Valley's scene is compact enough to cover properly in a day: estate vineyards along Oak Creek, tasting rooms in Cottonwood's old town, and pours that routinely surprise people who didn't know Arizona made wine at all.
