Guiborat’s Prismis all about chalk. A rich, racy and layered Chardonnay with breadth and length, and a myriad of complex aromas and flavors for the true Cote des Blancs lover.

The NV Extra Brut Blanc de Blancs Prisme Grand Cru (2019 base) is terrific. I admire its dynamic energy and verve, both of which are on full display. White pepper, chalk and mint cut through a sizzling core of Cte des Blancs fruit. The blend of sites in Chouilly and Cramant works so well here. This release is based on 2019, with 17% reserve wine blended in from the previous year’s release. Dosage is 2.5 grams per liter. Disgorged: November 2023.– ByAntonio GallonionMarch 2024

Sourced from 3 parcels in Grand Cru villages in the Cote de Blancs. From Cramant Les Bergeries (planted in 1984) and from Chouilly- Le Mont Aigu (planted in 1970 and 1979) and Les Caurs (planted in 1946 and 1998). Deep chalk soil. The older vines of Chardonnay (all are 15-50 years old), from parcels which give the best expression of the chalk make up the cuvee Prisme. For Prisme only the first juice of the press is used. The grapes from each parcel are kept separate and vinified individually in stainless steel (94%) and neutral 400 liter barrels (6%) to keep the identity of each terroir. After fermentation the base wines have a lengthy elevage on their lees (at least 7 months) until assemblage and bottling the following Spring. In Richards quest for an absolute minimum of intervention and transparency, malo is blocked on the base wines. The goal of Prisme is an emphasis on the chalk of Cramant and Chouilly. Currently 2013 vintage. Aged for a minimum of 40-44 on the lees months in the chalk cellars beneath the winery before disgorgement. Dosage of 2.5 g/l. Aged an additional 6 months after disgorgement before release.
