Hi Carson
Often ‘less is more’, so be a little wary of adding other distractions in… unless those other distractions are to bring some balance for a travelling companion, in which case let us know what they’re looking for as well.
If you have a full week in the Langhe, then you could do a lot of tasting, some superb walking through the vineyards (Yay! for shared ownership → open access), plus enjoying a day trip into Alba (and/or Asti) for a historic town. Plenty of other places of interest nearby, but for 6-7 days, the above should keep you busy. The Langhe, Roero (and now Monferrato) tourist office is excellent, and there site will give you some ideas of other things to do there (e.g. a balloon flight?), plus they had extensive listings for wineries, but not sure if that’s been spun off onto a sister site.
Others can advise on those French wine regions, however if you want to do both to a decent degree, I’d challenge on whether it’s sensible to add the Langhe in as well.
Best is a term that’s difficult to answer, as the only objective way typically ends up as ‘most expensive’, but that wouldn’t be what I look for. What I would recommend, is picking a village e.g. Serralunga d’Alba, and looking at the wineries there, and planning (say) 2 in the morning and 2 in the afternoon, with a good lunch inbetween. On a quieter day, perhaps do something else in the morning, but slot in a winery visit or two in the afternoon. In that way you might start to get a feel for the variations between villages & producers, but mostly you’re not spending time driving everywhere.
Where to stay?
Loads of choice, from a quiet village like Verduno, to the becoming rather touristy Barolo, with lots in between, and a couple on the fringes that are quieter still. We’ve also stayed a short distance away and that can work as well e.g. Corneliana d’Alba & Santa Vittoria d’Alba. Plenty of good accommodation, including a number linked to wineries (see somewhere like Agriturismo.it). Given the time you have, I’d suggest a single base, driving to other villages, but having a day in the middle devoted to your base village, so you can leave the car parked up and walk there and back. It’s quite sensible to let the accommodation that appeals to you drive where you stay.
A couple of wineries that impressed us (amongst many): Albino Rocca in Barbaresco (and walkable from the village), who have a wide range yet seem skilled across that range, including some very impressive whites. Schiavenza in Serralunga d’Alba are a young family, working very hard and with a questing attitude in both winery and restaurant. Boh are good and good value IMO, but I also expect them to be one that improves over time, based on their drive.
