I-40 from Asheville to TN is a crap drive fwiw. Not much for bottleshops in Asheville since tasty closed. App Vintner is maybe 15 minutes from I-26, not sure how the selection is, haven’t been in years. The other ok option is a semi-sketchy gas station called Hot Spot on Leicester Hwy. They usually have a good selection of NC stuff. It’s 5-10 min from 240/26 interchange.
Zillicoah isn’t letting kids in, so that might hamper your pickup plans. If you’re going to stop at Zebulon, say hi. I’m usually there on Fridays.
