There is an excellent profile of Domaine Roger Sabon in Vinous Media by César Rivière. If you have a subscription you can read it here and see a video of vigneron Didier Negron discussing destemming, maceration and when he decides to pick.
Having visited and tasted with Didier and the extended Sabon family last December, it was a remarkable to taste a full range of 2013s, that despite the difficulties of the vintage, were as compelling as anything made at this address in previous years. While past vintages showed poise, recent years have seen some changes in the cellar where Didier has been moving away from barrels in favor of foudres and replacing barriques with demi-muids. Similar to Marcoux, Domaine Roger Sabon has a significant proportion of their holdings on sandier terroirs in the north of the appellation as well as a fairly large proportion of mainly old-vine Syrah which is harvested early to prevent overripeness while retaining the varietal’s natural acidity. These remain insider wines that are reasonably priced, charming in their youth, complex and quite friendly at the table.
