Tasting notes

Skeveldra is one of the most singular expressions of Sauvignon Blanc in the Loire: the combination of 50-year-old vines on pure silex soils, late-harvest botrytis, and 24-plus months on lees in old barrels produces a wine with the tension of Sancerre and the textural depth of something far older and stranger. The flint-driven minerality, ginger spice, and saline finish are unmistakable and age-worthy.

Skeveldra is a single-vineyard Sancerre from a roughly 1-hectare parcel in the commune of Saint-Satur, planted on soils with a high concentration of silex (flint). The name comes from the Lithuanian word for stone fragment, a reference to the abundant flint shards in this specific plot. Vines average 50 years old. Yields run around 20 hl/ha — roughly one-third of the Sancerre appellation average.

The grapes are harvested by hand at full ripeness, often with a significant portion affected by botrytis. Fermentation is spontaneous in old barrels (10 to 15 years old) using indigenous yeasts, and the wine undergoes complete malolactic fermentation. It is then aged on its fine lees in the same old barrels for an extended period — typically 24 to 36 months — before being bottled by gravity, unfined, unfiltered, and with zero added sulfur.

The result bears little resemblance to conventional Sancerre. The deep golden color reflects both the extended barrel aging and the late-harvest botrytis. On the nose: flint, white peach, pear, ginger, and a saline undercurrent. The palate is intense with bracing acidity, a supple texture from lees contact, and a long mineral finish. Decanting is recommended — the wine takes time to open.

The estate, Domaine Etienne et Sébastien Riffault, is certified organic (Bureau Veritas) and farmed biodynamically (Demeter). Riffault is a member of the Association des Vins Naturels and the Renaissance des Appellations.

The saline, mineral quality of Skeveldra is a natural match for oysters, raw clams, and other shellfish. Its acidity and body also hold up well alongside aged goat cheese — the local Crottin de Chavignol is the classic pairing. Roasted river fish or a simple preparation of sole or turbot also work very well.

Important Compliance Requirements

FedEx and other carriers we might occasionally use can only deliver wine to customers who are 21 years or older. Someone must be at the address to receive the package, carriers don't just drop a package and leave. They must ensure the person receiving the wine is 21 or older.


Re-shipping a Package

If a package is returned to us after three failed delivery attempts, we can only re-ship the wine upon payment of a re-shipping fee, to be determined based on the shipping address and number of bottles. Shipping wine is extremely expensive. We are sorry about this, but we have no other choice. Please make sure there's always someone at the address you enter as your shipping address.

If you'd like to receive a refund for a package that was returned to us after FedEx made three delivery attempts, we can do that but we must keep a $20 refund fee; FedEx charges us a lot of money for returns, unfortunately, I can't stress this enough.

If you'd like to reroute a package after it's been shipped, we can do so for a $20 re-routing fee. We cannot re-route a package across state borders. For any change of address, please contact us as soon as possible, ideally within 1-2 days from placing the order or we cannot guarantee we'll be able to reroute or change your order's shipping address.


Canceling an Order

If you'd like to cancel an order after it's been shipped, we can do so upon payment of a small cancellation fee – the amount depends on the size of the order. Carriers charge us a lot of money to recall a package en-route.

We are not responsible for heat- or frost-related issues. We offer ice-packs upon request. Please let us know if you think that there could be heat-related issues. If we don't hear anything from you regarding weather issues before an order is shipped, or if you don't request a hold due to the weather, we are not responsible for heat/frost damage.

Producer profile

Sébastien Riffault

Sébastien Riffault, son of Etienne Riffault, launched his own label in 2002 at age 21, starting with a small parcel at a time when organic or biodynamic viticulture was essentially nonexistent in Sancerre. The domaine, known as Domaine Etienne et Sébastien Riffault, is based in the village of Sury-en-Vaux and works approximately 12 hectares of vines. The estate has been certified organic since 2007 and converted to biodynamic practices starting in 2004, with Demeter certification. Riffault is a member of both the Association des Vins Naturels and the Renaissance des Appellations.

Farming is entirely chemical-free. Riffault works a portion of his vineyards by horse — specifically the parcels with vines aged between 35 and 70 years old — to avoid compaction and preserve soil biology. Cover crops of grasses, flowers, and plants are maintained between vine rows to support biodiversity and beneficial insects. Yields across the estate run well below the appellation average, a result of old vines, poor soils, and the refusal to use fertilizers.

In the cellar, Riffault harvests late by Sancerre standards, targeting full ripeness and accepting significant botrytis in some cuvées. Skeveldra typically sees around 50% botrytis. Fermentation is spontaneous in old oak barrels using indigenous yeasts, and all wines undergo full malolactic fermentation. The wines are aged on their fine lees for extended periods — 24 to 36 months depending on the cuvée. No fining, no filtration, and no added sulfur (with the sole exception of a minimal dose in Les Quarterons at bottling). Wines are bottled by gravity.

Wine region

Loire Valley, France

Sancerre is an AOC in the eastern Loire Valley, located on the west bank of the Loire River approximately 200 km south of Paris. The region spans 14 communes, including Saint-Satur, Sury-en-Vaux, Bué, and Chavignol. Vineyards sit on hillsides between 200 and 400 meters elevation with a semi-continental climate: warm summers, cold winters, and spring frost risk moderated in part by the Loire River. Only two grape varieties are permitted: Sauvignon Blanc for whites and Pinot Noir for reds and rosé.

Sancerre's soils divide into three main types. Terres blanches are Kimmeridgian clay-limestone marls found in the west, producing structured, ageworthy whites. Caillottes are Oxfordian limestone gravels near the town itself, yielding more aromatic and early-drinking wines. Silex — clay soils with high concentrations of flint — occur in the eastern zones bordering the Loire, including Saint-Satur and Thauvenay. Silex sites accumulate daytime heat and release it at night, accelerating grape maturity; the wines produced on these soils are known for intense minerality, a smoky or gunflint character, and strong aging potential.
