Pinot Blanc

Identity

Pinot Blanc is the most understated of Alsace's grapes: none of Gewurztraminer's aromatics, none of Pinot Gris's richness, none of Riesling's minerality. That is precisely what makes it the ideal base for Crémant d'Alsace — a grape that doesn't try to dominate a blend, but gives it its backbone.

Medium bunches, regular production more generous than the other Pinots, moderate vigour: Pinot Blanc makes pleasant, lightly full-bodied wines with medium acidity — never aiming for the complexity asked of its Alsatian cousins.

History and origin

Pinot Blanc belongs to the Pinot family. The Vitis International Variety Catalogue (VIVC, no. 9272) states its parentage as a Pinot Noir mutation, but explicitly notes that this parentage is not confirmed by genetic markers — unlike this corpus's Pinot Gris and Pinot Meunier, both confirmed by the same method. An uncertainty that sets Pinot Blanc apart even within its own family.

One naming trap deserves to be stated firmly: "Auxerrois" appears among the historical synonyms the VIVC records for Pinot Blanc. Yet Auxerrois is, in Alsace as in this corpus, an ampelographically distinct variety, with its own passport entry — a confusion of names that goes back a long way in ampelographic history, but never an identity between the two grapes.

In the vineyard

According to the Pl@ntGrape datasheet (no. 216, consulted in session), Pinot Blanc buds one day after Chasselas, the reference variety, and ripens as early as the first period, a week and a half after it: an early grape at every stage, more so than an earlier estimate had suggested. Its vigour stays moderate, but its production is regular and more generous than Pinot Gris's or Pinot Noir's — a practical advantage that partly explains its popularity among Alsatian growers.

The variety stays fairly delicate, relatively susceptible to the vine's major diseases — powdery mildew and grey rot chief among them. It suits deep, fairly warm soils, whether stony or not, and suffers mildly from chlorosis.

In the glass

On the nose, a simple, clean register: pear, green apple, a touch of lemon, rounded out with a floral note of acacia. Ageing adds almond and a mineral chalky note.

On the palate acidity stays moderate (2 to 3), body and alcohol discreet (2 to 3): Pinot Blanc never seeks power. With age, in the best cuvées from controlled yields, hazelnut and a hint of honey appear — never dominant, but enough to tell an evolved Pinot Blanc apart from a still-young wine.

Great terroirs

Alsace is its benchmark terroir, one of the appellation's seven historic varieties. There it often shares the usage designation "Pinot Blanc" or "Klevner" with Auxerrois — the two grapes frequently vinified and labelled together, a practice that deliberately blurs, for the consumer, the ampelographic distinction this corpus nonetheless insists on. It is also the most common base for Crémant d'Alsace, where its aromatic neutrality and measured acidity suit the second fermentation well.

The AOC Champagne rules also list it among the appellation's "principal varieties," though its actual planting there stays very limited, shared with Arbane, Chardonnay Rose, Petit Meslier and Pinot Gris.

Commonly confused with

Auxerrois, already flagged as a VIVC naming trap, is the most frequent confusion on the ground: the two grapes are often vinified and labelled together in Alsace, under the same usage designation. Auxerrois is generally richer and less acidic than Pinot Blanc, which keeps a tauter profile.

Pinot Gris, a direct cousin in the same Pinot family, is told apart by a far deeper yellow colour and an aromatic richness — ripe pear, quince, smoke with age — that Pinot Blanc never reaches, staying in a more discreet register.
