The Grand Cru Terroirs Blanc de Blancs is Agrapart's main cuvee, blending fruit from four Grand Cru villages; Avize, Cramant, Oger, and Oiry.
Roughly half of the blend is made up of reserve wine, and it spends four years on lees before disgorgement, making for a blisteringly-good Champagne of quiet complexity and power.
This is not a rich, yeasty style though; it is a Champagne of pure Chardonnay freshness and zest, with a stunning, chalky intensity.
If you're in the market for an elite Blanc de Blancs, you'll find no better value than this offering from Pascal - it beats prestige large house wines into a grapey pulp!
