There's several wineries in the Smoky Mountain area including a dense area called "Rocky Top Wine Trail" which consists of 3 wineries within 3 miles (Hillside, Apple Barn, & Mountain Valley Winery). In this article, I'll compare two of them vs. Mountain Valley winery.
Overall, I'd suggest including a winery as a portion of your Smoky Mountain schedule. When I've traveled through wine country in Sonoma, CA or eastern, MI, you could fill the whole day happily wandering through grapevines and visiting wineries. However, in the Smoky Mountains, I'd suggest you get outside and perhaps visit one or two wineries as a romantic ending to the day. Therefore, I'd suggest being choosy in which ones you visit.
I recommend Smoky Mountain Winery (Gatlinburg, TN) over Mountain Valley Winery or Hillside (both Pigeon Forge, TN). While all had nice regional sweet wines, the real difference for me was the level of service. At Smoky Mountain Winery, the lady gave me a warm welcome and gave me her full attention. With such service, I was able to overlook that the samples came in a shot glass instead of a wine glass and have a conversation about the wine. At Mountain Valley Winery and Hillside, no one even greeted me and it felt like they were really set up to crank through the tour buses and take orders. Smoky Mountain Winery tasting room is much smaller and I think you'll enjoy the quaint atmosphere and service.
After I made my assesment, I searched online to see other traveler's viewpoint:
Smoky Mountain Winery:

You don't need to fly over the ocean to try out these new adventures. Just drive to the Smoky Mountains. At Ober Gatlinburg, you can ride the alpine slide down the mountain on a wheeled cart. It's a blast! This was the most fun ride at the park. As you ascend the mountain on your chairlift, you can watch riders go down screaming and laughing with joy. Jump off the chairlift and get in your own cart. As an employee explained physics - weight and gravity help. If you are racing down the track with your competitive son, you finally have the advantage (-:
WHO: big kids & adults; 6 & under ride free with adult (due to chairlift with no seat belt, I wouldn't recommend this for little kids)
