Jamet is a giant of a name in Cote Rotie. It’s one of a tiny handful of domaines that have been bottling wines consistently since the 1970s, sticking for the most part to a traditionalist regime.But in 2013, a big change occurred. The two Jamet brothers who ran the domaine split up. Jean-Luc Jamet, who managed the vineyards, left with half of the family holdings to start making wine under his own name.
