Terroir explained: Why does the same wine taste different depending on the region? The interplay of soil, climate, and the human hand.
Terroir (French, pronounced: "Ter-roar") is the interplay of all natural factors that give a wine its unique character. It is what distinguishes a Riesling from the Rheingau from one from Alsace.
The subsoil fundamentally influences the wine:
| Soil Type | Effect | Regions |
|---|---|---|
| Slate | Mineral, elegant | Mosel, Rheingau |
| Limestone | Taut, acidity-driven | Burgundy, Champagne |
| Gravel | Well-drained, concentrated | Bordeaux (Médoc) |
| Clay | Powerful, full-bodied | Pomerol, Tuscany |
| Volcanic | Smoky, mineral | Etna, Santorini |
The macroclimate of a region determines:
The local conditions of an individual parcel:
"Two vineyards, only 100 metres apart, can produce entirely different wines."
Choosing the right grape variety for the terroir is decisive:
Even if purists are reluctant to admit it — the winemaker is part of the terroir:
How does one recognise terroir in the glass?
Typical terroir characteristics:
Examples:
Wines with strong terroir expression show:
There are two camps:
Traditionalists: "Terroir is everything — the winemaker should simply express it."
Modernists: "The technique and skill of the winemaker are at least equally important."
The truth probably lies somewhere in between: great terroir needs a skilled winemaker, and a skilled winemaker needs good terroir.
The concept originates from France, but applies universally:
Terroir (French) is the interplay of all the natural factors that give a wine its unique character. It is what distinguishes a Riesling from the Rheingau from one from Alsace.
Terroir includes soil (e.g. slate, limestone, gravel), the climate of the region, the local microclimate of an individual parcel, the matching grape variety and also the human element – the grower's cultivation methods, picking date and cellar techniques.
Typical terroir characteristics are minerality (slate, chalk, flint), salty notes near the sea, the herbaceousness of Mediterranean garrigue and smokiness on volcanic soils. Examples are the chalky minerality of Chablis or the slatey petrol notes of a Mosel Riesling.
The subsoil shapes the wine fundamentally: slate makes it mineral and elegant (Mosel, Rheingau), limestone taut and acid-driven (Burgundy, Champagne), gravel well-drained and concentrated (Bordeaux Médoc), clay powerful and full-bodied, volcanic soils smoky and mineral.
Yes – even if purists are reluctant to admit it, the winemaker is part of the terroir. Cultivation methods, picking date, cellar techniques as well as tradition and experience all belong to it. Great terroir needs a capable winemaker, and a capable winemaker needs good terroir.
