p.s. if food is a hobby, the google map I created 'Torino food explorer' may be of interest.

It's now about 4 years since we've been, so a few may have closed, but others opened.
Are you planning to drop the car off in Torino (or picking it up there)? Despite it being a city of cars from the FIAT HQ, like many Italian cities, it's not a great place to drive and has a huge ZTL (effectively the whole of the central rectangle that defines the city centre).
The drive from Torino to the Langhe isn't a bad one at all, likely to be busy, but straightforward if driving out of Torino, then pretty steady on the Autostrada. The only 'funky' junction I recall is the one outside of Alba on the junction of the Bra road with the one heading down into the heart of the Langhe. Worth looking that one up on Google maps beforehand.
In terms of booking wineries, we tend to email direct to arrange. Many have English speakers, but writing in Italian probably gets a faster response. Alternatively the excellent tourist office did set up a booking service. They also have a good listing of contact details for wineries.
Visits used to average out at 90 mins each, so for instance it's ideal to have 2 in the morning (say 9 or 9:30am for the first). It's usually very easy to find two places of interest that are neighbours.
