This exceptional RD has been resting ‘sur latte’ for ten years, and was disgorged in 2015, with no dosage. What a bargain! If this was champagne it would be 5 times the price. The nose is an incredible display of wild mushrooms, marshmallow, honey and quince. Despite the age it is extremely fresh but with 10 years of lees-y concentration. With fragrance, complexity and depth, this is eye-opening Loire sparkling.
