96 Points - Wine Enthusiast:  Aged for eight years on the lees before disgorgement, the Champagne is deliciously toasty with acidity and fine dryness.

95 Points - Jeb Dunnuck:  Disgorged in January of 2023, the 2013 Champagne Millésime Brut was the last vintage from the cellar master for Heidsieck prior to Cyril Brun. The 2013 Champagne Millésime Brut is a bright straw yellow color and is based on the crus of Les Mesnil, Avize, Averney, and Aÿ. It’s fresh with aromas of wet stones, fresh quince, and fresh jasmine flowers. It has a chalky and focused texture, with ripeness to balance it out, and a long, graceful finish. At this stage, it feels more forward with 57% Pinot Noir and the rest Chardonnay. A more mineral-tinged expression, it has a lot of charm and the promise of longevity over the coming two decades. Drink 2024-2044. It will be interesting to see how the Pinot shows itself over time. 8 grams per liter dosage.
