I would honestly say 2 is good, I wouldn’t pressure too much with 3. The only reason is really spending time in cellars, and having a leisurely lunch will eat up a good chunk of the day - one morning, one afternoon. Jeremy’s tastings at Dujac are quite fantastic - so hopefully he gets back to you! I really like the tasting/tour at Henri Gouges - and given its breadth of NSG, it is a delight to taste - a paid tasting yes, but given quality, a nice spot as well. It certainly wouldn’t be a bad thing to contact a few folks and see if you can visit. Pousse d’Or seems to be quite friendly and accomodating in Volnay (they coravin out of bottles, so I think they welcome folks quite often) and it’s a broad tasting. Genot Boulanger in Meursault is one I’m planning on next time, along with some old favorites. With the short 2024 and 2025, those who don’t do tasting may not be willing to invite a ton of folks in, but it’s worth asking!
I’ll be out in Bordeaux/Burgundy around the same time - it is a lovely time of year to visit.
