Provence area wine tasting

Provence is quite large. Where will you be based? There's no need to travel far for a wine tasting/tour in the area.

Thinking of staying in Saint Rémy right now

OK. I am more familiar with options in central-eastern Provence than in western-northern Provence, so I don't really have specific suggestions for you. I'm sure others will chip in.

South of St Remy I can recommend Mas de la Dame winery. They have tours and tastings and a nice little shop. https://masdeladame.com/en/tasting-tours/ I liked both their wine and olive oil enough I ordered a case after I got home! And it is a pretty drive just a few miles from SR.

Rick's Provence guidebook recommends several guided one day and half day tours that look interesting. I will be in Provence in October and will research them further. Last November as part of a Viking cruise we toured two Chateauneuf-du-Pape and a Beaujoulais winery.

We toured Chateau Romanin near Saint-Rémy-de-Provence,
