There are SO many great reviews for this, so let’s go with Dunnuck:
Bollinger's NV Special Cuvée knocks it out of the park. Made from 60% Pinot Noir, 25% Chardonnay and the rest Pinot Meunier, with 30% of the blend brought up in barrels, it boasts a rich, deep, medium to full-bodied style as well as terrific notes of lemon curd, crème brûlée, caramelized stone fruits, and hints of toasty nuttiness that develop with time in the glass. It's a big, rich Champagne that stays balanced and pure. Beautiful stuff.
Or the 96-point one from Decanter:
The complexity and richness of Special Cuvée is unparalleled among the entry non-vintage blends of every Champagne house, short of ascending to the mesosphere of Krug. Its grand recipe explains why, built on incredible depth of 50%-60% reserves. Triumphant complexity is a given at Bollinger, but it’s the dynamic freshness and vitality that really set it apart as one of the most affordable Champagne benchmarks.
