Larmandier-Bernier Longitude Champagne 1er Cru Blanc de Blancs Magnum white

Larmandier-Bernier Longitude 1er Cru Blanc de Blancs in magnum format is a quintessential grower Champagne: precise, mineral-driven and deeply expressive of the Côte des Blancs. Crafted entirely from Chardonnay, this non-vintage cuvée draws its name from the near-straight line of top crus that lie along the 4th meridian east, forming a pure chalk spine through Champagne. In magnum, Longitude gains even greater finesse and aging potential, making it an excellent choice for collectors and for the table alike.

Tasting Notes
In the glass, Longitude shows a pale, luminous straw color with fine, persistent bubbles and a delicate, silvery rim. The mousse is creamy yet energetic, hinting at both concentration and tension. The nose is refined and chalk-inflected, opening with notes of lemon zest, green apple, and white flowers, followed by subtle tones of almond, fresh brioche, and wet stone. With air, more complexity emerges: hints of pear, grapefruit pith, crushed oyster shell and a faint saline breeze that is very Côte des Blancs. On the palate, this Extra Brut is taut, linear and extremely precise—dry but not austere. Citrus fruit, green pear and crisp apple are framed by a pronounced chalky minerality and a touch of hazelnut and pastry from extended lees contact. The finish is long, saline and mouthwatering, with a beautiful sense of lift and purity. In magnum, the wine evolves more slowly and harmoniously; while already compelling on release, well-stored bottles can comfortably develop additional complexity and creaminess over 8–12 years, gaining more brioche, honeyed and nutty nuances while retaining their underlying freshness.

Production
Longitude is sourced from biodynamically farmed Chardonnay vineyards in the Grand Cru villages of Cramant, Avize and Oger, as well as the Premier Cru village of Vertus—sites that trace a near-linear path along the Côte des Blancs on the 4th longitude. Here, deep chalk subsoils and cool exposures give the wines their hallmark tension, salinity and finesse. All grapes are harvested by hand at optimal ripeness to preserve natural acidity and aromatic precision, then gently pressed. The cuvée is composed each year from around 60% wines of the current vintage and 40% from a perpetual reserve started in 2004, bringing both energy and layers of maturity. Fermentation typically takes place with indigenous yeasts, often in a mix of stainless steel and neutral oak, followed by extended aging on the lees to build texture and complexity. Bottled with a very low dosage as an Extra Brut, Longitude clearly reflects its terroir and the house’s minimalist, terroir-first approach.

Food & Serving
This finely etched Blanc de Blancs is a superb match for oysters, fresh shellfish, and crudo, where its saline edge and citrus brightness shine. It pairs equally well with delicate fish dishes, sushi and sashimi, scallops, lightly smoked salmon, or simple dishes featuring fine ingredients like grilled turbot, sole meunière or a tart of young goat’s cheese and herbs. For cheese, opt for fresh chèvre, young Comté or mild bloomy rinds rather than strong, washed-rind styles. Serve well chilled but not icy, ideally around 8–10°C (46–50°F), allowing the wine to warm slightly in the glass. In magnum, a brief, gentle aeration in the glass is usually sufficient; decanting is not essential, but pouring the first glass and giving the bottle a little time on the table will help the wine open and reveal its full aromatic range.

Producer
