What is late harvest wine?

Late harvest wine sounds straightforward — just pick the grapes late, right? But the reality involves calculated risk, nervousness about weather, and an intimate understanding of how each extra day on the vine changes the wine.

In Alsace, where late harvest (Vendange Tardive) has been a legally defined category since 1984, the regulations are precise. Riesling must reach a minimum of 243 g/L natural sugar; Gewurztraminer needs 270 g/L. No sugar can be added (chaptalisation is forbidden), and picking must be done by hand. Winemakers sometimes wait until late October or even November, gambling that rain or frost won't destroy the crop.

The concentration happens through two natural processes. First, simple dehydration on the vine: warm autumn days evaporate water from the berries. Second, if conditions are right, botrytis may start to develop, adding another layer of concentration and complexity. But unlike Sauternes, botrytis isn't required for VT — it's a bonus, not a prerequisite.

What surprises many people is that late harvest wines aren't always sweet. If the yeast ferments all that sugar, you get a dry but incredibly intense, high-alcohol wine. Some producers aim for this style. Others stop fermentation early to retain sweetness. The label usually doesn't tell you — which is part of Alsace's (in)famous unpredictability for consumers.

Germany's equivalent ladder — Spätlese, Auslese, Beerenauslese, Trockenbeerenauslese — provides more guidance, with each level indicating increasing grape ripeness and typically increasing sweetness. A Spätlese Riesling from the Mosel can be one of the most electrifying wine experiences on the planet.
