Terroir is above all a concept established by the INAO (Institut National des Appellations d'Origine). It defines terroir as the combination of soils and climates corresponding to a delimited vineyard, giving a specific character to the wine produced. Forged by two millennia of viticultural history, this typically French concept — which has no linguistic equivalent in other languages — occupies a primordial place in the specifications of the various appellations. Linked to a soil and a climate within a defined geographical zone, accompanied by human action, terroir guarantees both the quality, the inimitable character and the origin of the wine.
It is precisely this notion of terroir that underpins the legitimacy of the great French appellations — from Burgundy to Bordeaux, from Champagne to the Rhône Valley — and that justifies their worldwide recognition as absolute references of excellence in viticulture.
Highly subjective, the term "terroir wine" is often at the centre of certain disagreements in the wine world. Extremely difficult to define from a purely gustatory standpoint, it is generally recognised by its typicity. Indeed, it possesses its own personality — a particularity that implies a genuine element of risk, in opposition to so-called "standardised" wines. As an expression of its terroir, the wine is associated with a region, its place of production, the climate, the parcels from which the berries originate, the farming practices and the expertise of the winemaker.
The great terroir wines stand out for their ability to faithfully reflect a precise place, a particular vintage and a production philosophy. It is this uniqueness that gives great wine estates their value in the eyes of importers, wine merchants and enthusiasts worldwide.
If wine is considered a reflection of its terroir, the winemaker's work impacts on the finesse of this expression. When speaking of terroir, one thinks of natural factors such as the soil, subsoil, vine, grape varieties, climate, exposure, slope or geographical location, and finally the presence of a waterway (estuary, river, stream). But there is also a primordial human factor that influences the typicity of a wine and its organoleptic qualities.
Thus, from generation to generation, this human touch has been refined. Winegrowers have catalogued what they considered to be good terroirs over the years and distinguished them through official classifications, lieu-dit names or village of origin. This choice of the best land, farming practices and adapted grape varieties — which seems obvious today — required centuries of observation and research.
The biodynamic approach, which considers the vineyard as a living organism in permanent interaction with its environment, today represents the most complete expression of this terroir philosophy. Estates such as Domaine Leroy or Zind-Humbrecht embody this vision of a living terroir, shaped as much by nature as by the hand of man.
The notion of terroir was, in the early works of French geographers, presented as exclusively descriptive and restricted. Broader today, it is often confusing for foreigners. The primary role of terroir remains to understand how an environment functions in order to adapt to this behaviour and create a wine that is its own. This study takes into account a natural, agronomic (plant and grape variety growth) and oenological approach (through the implementation of parcel-by-parcel vinification). A plurality of elements that create the particularity, uniqueness and typicity of a wine.
It is this quest for unique terroir expression that explains why two wines from neighbouring parcels can be radically different, and why the world's great sommeliers devote their careers to deciphering its subtleties. Terroir is not a constraint — it is a signature.
While terroir is a profoundly French concept, it has progressively conquered the entire wine world. Italy with its Tuscan appellations, Spain with Rioja and Priorat, Germany with its great Riesling grands crus, and the new worlds — Napa Valley, Marlborough, Barossa Valley — have all adopted a terroir approach to valorise their productions and justify their move upmarket.
International buyers are increasingly sensitive to this notion: an identifiable, traceable and authentic terroir wine is today a first-rate commercial argument on all premium markets worldwide.
