(94+ points) Based on the 2019 vintage with 30% of reserve wines in the blend, the Larmandier Bernier Longitude Blanc de Blancs Extra Brut Premier Cru NV was harvested quite ripe for the vintage and vinified in a combination of stainless steel, large barrels and barrique; sur lie during the winter. It was finished with a four grams per liter dosage. It opens with toasty and rich aromas of apple pie, butter croissant, white flowers, Manuka honey and a good whiff of mineral freshness. The light to medium-bodied palate has a beautiful, broadly knit mouthfeel enlivened by silky, stimulating acidity. It finishes long and concentrated. - Sarah Mayo

There's an extra dash of mineral energy and zesty length in this cuvée Longitude, which brings together fruit from Larmandier-Bernier's home village of Vertus with other fruit from the Côte des Blancs, over the true entry level Latitude that tends to make it worth trading up. Subtly creamy and peppery, yet fulsome in white peach, pear and lemon oil, it gains a savoury, umami depth from 40% addition of perpetual reserve. Always a model non-vintage blanc de blancs.

A base of 2015 vintage (it is normally one year older than Latitude). The striking, crushed-chalk and lemon aromas here are so pure. The palate has a very smooth, crisp and fresh array of attractively vibrant, dry, lemon flavors. Long, pure and dry. Drink now.

The NV (2021) Extra Brut Blanc de Blancs Longitude 1er Cru shows the lighter, airier side of the year. Crushed rocks, lemon peel, white pepper, slate and chalk all confer brightness. This sculpted, saline Blanc de Blancs is impeccable. The Longitude is a blend of parcels in Vertus, Cramant, Avize and Oger. Dosage is 2 grams per liter. Disgorged: April 2024; multiple disgorgements throughout the year. -- Antonio Galloni

A bright medium yellow hue, the NV Champagne Longitude Extra Brut has more focus and a compact, linear drive from more chalky soils, with notes of lemon candy, Anjou pear, and a very pretty floral perfume. Medium-bodied, it has a refreshing and fine mousse, with pleasing lift and a clean finish. A total charmer, I would drink this all day. It's pure and crisp yet has a pleasing, approachable feel. Drink 2025-2035. Dosage is 2 grams per liter.

A considerable increase in intensity and tension compared to Latitude, Larmandier's excellent NV Extra-Brut Blanc de Blancs Longitude is crafted from a 2021 vintage base (60%) and combined with a perpetual reserve component. Disgorged in April 2024 with two grams per liter dosage, it is medium-bodied, taut and incisive in personality. Sourced from the villages of Vertus, Oger, Avize, Cramant and Chouilly, it offers aromas of white flowers, citrus fruit and oyster shell. Tangy acidity, informed by the long and cool growing season, with mineral-laden undertones, leads to a chalky, long-lasting finish. Expect a tauter, less ample Champagne compared to the last year’s edition. - Kristaps Karklins
