White wine. Sancerre, Loire Valley, France. Sustainable. 100% Sauvignon Blanc. Around 40 year old vineyard, mainly from chalky soils called “caillottes” with some deeper soils owning more clay called “terres blanches”. Bottled without filtration. There is a chalky sense of mineral impingement to the vibrantly zesty, invigorating, yet persistently succulent finish of this buoyant wine.

White wine. Sancerre, Loire Valley, France. Sustainable. 100% Sauvignon Blanc. 65 year old vines, hand-harvested and fermented and aged on the lees in large oak tronconique. Bottled unfiltered. On the palate, this old vines Sancerre from chalky silt soils is lovely, pure, tight and salty; it has an austerely firm and seriously mineral character, with grip, tension and a persistent terroir expression.

Red wine. Sancerre, Loire Valley, France. Sustainable. 100% Pinot Noir. This Sancerre rouge is silky textured, fresh and with fine yet firm tannins, and a remarkable finesse and delicacy. It is well structured with moderate alcohol and is lovely to drink today. The grapes have been perfectly selected on the sorting table, before they were de-stemmed. The wine was then aged in wooden vats and 500-liter barrels.

Red wine. Sancerre, Loire Valley, France. Sustainable. 100% Pinot Noir. Jumps from the glass with floral aromas of cherry and red currant. Shows a light-handed toast with plenty of earth and minerality. On the palate the wine is full-bodied, focused and nicely sappy at the core, with excellent transparency, impeccable balance, tangy acids and a long complex finish.

White wine. Sancerre, Loire Valley, France. Sustainable. 100% Sauvignon Blanc. Typical Sancerre citrus and herbs on the nose—only from this cuvée, these notes explode from the glass. Beautifully textured throughout the mid-palate, this has the most mineral-laden finish of the trio of outstanding whites. There is a wonderful sense of untamed energy throughout, that no doubt could uncoil itself for the better part of a decade.

Red wine. Sancerre, Loire Valley, France. Sustainable. 100% Pinot Noir. A great example of Pinot Noir from these chalky soils, offering a nose of cherries, coffee, and herb tones. On the palate, it's deep and classy, focused and well-structured, with a bit of tannin to resolve on the long, balanced finish. Already delicious, this should age quite well.

White wine. Sancerre, Loire Valley, France. Sustainable. 100% Sauvignon Blanc. The 2017 Chêne Marchand is from the eponymous lieu-dit in Bué and opens with a deep bouquet of citrus fruit, elderflower, jasmine and a hint of black currant. Full-bodied, very mineral and complex on the palate, this is a pure and lovely, yet densely woven and concentrated Sancerre; it has nutty flavors, a lot of salt and crushed (lime-) stones, as well as a very tight and persistent, refreshing finish.
