The 2015 Blanc de Blancs Heintz Vineyard takes time to open to aromas of crème fraîche, chalk, saline and honey-nut character over a core of ripe quince. It’s ultra minerally in the mouth with creamy, chalky, toasty flavors supported by a delicate, lacy mousse, and it finishes long, fresh and super detailed. This is an incredibly expressive, mineral-driven wine that will take time to show all its potential. (EB) 95+  (9/2020)

The 2015 Blanc de Blancs Charles Heintz Vineyard from Michael Cruse’s Ultramarine is a rich, powerful wine. Orange peel, almond, chamomile, butter and tropical overtones give the 2015 a good bit of raciness to play off its creamy, ample frame. The 2015 is overt and quite rich, with tons of the breadth that make Charles Heintz wines so distinctive. The radiance of the year really comes through nicely. Observant readers will note the 1% Pinot Noir listed in the blend; in 2015, the topping wine used was Pinot. Dosage is 2 grams per liter (AG)  (4/2020)
