Champagne Guiborat 'Tethys Blanc de Blancs' Grand Cru Extra Brut 2021

Téthys (base 2021) opens with pear, dried white flowers and pastry notes, then snaps into focus with vibrant acidity and a clean, mineral finish. Think Côte des Blancs energy: lifted florals, orchard fruit, and chalky drive with a fine, refreshing mousse.

Why we love it

Téthys is one of those bottles that over-delivers for “entry cuvée.” You get true Grand Cru Côte des Blancs character, made in a deliberately bright, low-dosage style, with just enough lees complexity to keep it feeling complete. It’s the kind of Champagne you can pour at the start of the night, then keep on the table through seafood, salty snacks, and dinner.

Winemaking

Guiborat is based in Cramant and farms top parcels in the Côte des Blancs, focusing their bottlings on a small “crown jewel” selection of sites.

For Téthys (base 2021), the wine is sourced from four Grand Cru parcels across Cramant, Chouilly, and Oiry. It undergoes 100% malolactic fermentation (a house choice that typically makes Téthys the most immediately charming wine in the lineup), then ages 7 months on lees in stainless steel before spending 24 months sur lattes, finishing with 1.5 g/L dosage.

Serving and pairing

• Serve: well-chilled, then let it open 5–10 minutes in the glass

• Pair with: oysters, crudo, sushi, shrimp cocktail, caviar, tempura, roast chicken, creamy cheeses (Brillat-Savarin, young Comté)
  The extra-brut finish and chalky drive make it especially good with salty, briny, and lightly fried foods.

Estate overview

Champagne Guiborat is a 5th-generation family estate (founded 1885) led today by Richard Fouquet and his wife Karine. While the family still sells a significant portion of fruit (including to major houses), they reserve their best sites for a small-production range that emphasizes purity, finesse, and terroir expression, typically in stainless steel with long lees aging in cool underground chalk cellars.
