Like the Crozes blanc, Delas's 2019 Saint Joseph les Challeys Blanc is a blend of 80% Marsanne and 20% Roussanne made and matured in stainless steel. Scents of crushed stone, lime and poached pear emerge on the nose, while the medium-bodied palate is smooth and silky in feel with ample length and intensity on the finish. I suspect this drink well for several more years.
