It's a word widely used, but not always understood. It’s very common to smell chalk in Chablis and Champagne wines. From: Managing Wine Quality: Viticulture and Wine Quality, 2010. Too often it's misused as a synonym for earthy notes. It also includes the location of the vineyard, the climate and even the (traditional) actions of the winegrower in the vineyard such as a certain type of pruning or soil maintenance. These factors are: soil, topography, climate, local flora and fauna, grape variety / clone and human practices (the human element of terroir is highly controversial!). Scientific evidence for a direct link between the minerals in the there actually a direct link between the soil on which the vine grows and the However, drawing similarities between scents and a shared vocabulary helps us to convey a wine’s profile. Back in the 1980’s, many of these ‘terroir-driven’ wines were actually affected by wine faults including cork taint and wild yeast growth ( brettanomyces ). Vine water status is a key factor in grape ripening and vintage quality for red Bordeaux wine. These grapes exhibit a chameleon-like feature. Journal of Wine Research. the ‘terroir’ of wine. aromas”, “the scent of shells” or “the scent of wet The physical Again, according to these studies, the correlation between soil and wine is indirect. Journal International des Sciences de la Vigne et du Vin. 151). water stress. Their availability to plants depends on the pH value of the soil (Fig. An international zoning group characterized terroir more broadly as “a complex of natural environmental factors,” while Wine Spectator critic Matt Kramer dubbed it a … Therefore, the choice According to these writers, such a practice encourages imprecision, implicitly supporting the myth that minerals are physically absorbed by vines and reflected in the wine. Yet the most zealous wine writers still advise against using the word “minerality” (or its more specific declinations) to refer to a wine’s profile. Often it really does seem like wine tastes of minerals (even though stones do not have any smell on their own). The soil is one of the aspects that determine We say a wine has goût de terroir, a French term for tastes we expect to find in a wine made from a specific place. ripening of the grapes. be copied at another location. The best soil is the one that provides the right amount of water in every circumstance. a study in Spain shows that clay soils produce grapes with more and more ripe My name is Antonio and this is my wine blog. Check your inbox or spam folder to confirm your subscription. soils with a good water status produce sparkling wines that contain more varietal aromas – floral and fruity aromas – than grapes that come from sandy soils. This lack of nitrogen occurs in particular with grapes an effect on wine quality. At first, this might seem a baffling thought. 2013. http://dx.doi.org/10.1080/09571264.2013.7931762. Van Leeuwen C, et al. The Champagne terroir is characterized by its climate, its soil and subsoil, as well as by its relief. Other factors of the “terroir” can also However, While rieslings from Mosel have a distinctive “tingling” sensation that we can only describe as slate minerality. Minerality can refer both to scent and taste. The importance of regional ties to the climate, soil and grape varieties is at the heart of terroir. Clay and organic matter in a richer soil determine the concentration of cations such as Ca2+, Mg2+, K+ and Na+ in the soil moisture1. “The soil has an effect on the aromas that are being developed”. In the two circumstances the soil is the same, but the mesoclimate is different. signal to the plant to stop the vegetative growth and to invest more energy in the other hand, is less suitable for viticulture. Today the term is very popular and is currently one of the wine world’s hottest buzzwords. References:1. grown on low-nitrogen (stony) soils1,6,7. However, a small water shortage during the Furthermore, in the Bordeaux, of the vine and the ripening of the grapes via its water status and the Such grape varieties include: pinot noir, chardonnay, nebbiolo and riesling. This set of factors influences the ripening and Aspect: If one talks about terroir, there are four important factors: soil type, slope (topography), climate and geology. Igneous soils can be either intrusive or extrusive, made from the cooling and solidification of magma or lava from within or without the Earth’s crust. Your email address will not be published. Here on Wine and Other Stories I will answer the question what is terroir? They are very sensitive to soil and climate variations. The underlying idea of minerality in wine is that you can perceive the characteristics of the soil in the wine. In acid soils, most trace elements have a high plant availability. moisture are determined by humus and clay. This is virtually impossible, and therefore only that the grapevine can absorb nutrients from the soil for the growth and At their best, it’s said that these grapes “express their terroir”. The soil change is quite sudden so vines only a few metres apart are growing in two different soils.” The fruit growing on the gravel never makes it into Eclipse, but is used for the rosé and the second label (Twelve Bells); whereas the fruit grown on the clays accounts for 30 to 50 per cent of the Eclipse. This definition seems to indicate that minerality is a taste akin to salitiness, and therefore perceived in the mouth. characteristics of the soil for example by keeping enough humus in the vineyard A poor stony soil is Weathering of these rocks can ensure the release of Do you always want to be kept informed of all WineScience articles? They have a very low perception threshold and can at higher concentrations be characterized as a wine fault. Conversely, in warmer regions, the sheer ripeness of the fruit can obliterate all the nuances bestowed by terroir. Apart from a difference in structure that one can feel with But minerality in wine can trigger some interesting discussions. Drought is a major hazard for viticulture. necessary for the absorption of nutrients from the soil and for the Organic and biodynamic practices can be beneficial to the overall taste of the wine for this exact reason. regions can use irrigation systems to prevent a water shortage and therefore González-Barreiro C, Rial-Otero R, Cancho-Grande B, Simal-Gándara J. However, the soil does influence the taste of the wine. A beginner's guide ~ Wine And Other Stories, Terroir and humans - a valuable symbiosis? Terroir is the basis of the French wine appellation d'origine contrôlée (AOC) system, which is a model for wine appellation and regulation in France and around the world. Sensory and chemical drivers of wine minerality aroma: an application to Chablis wines. taste sensation. Therefore we utilise analogies. Microorganisms break down the humus into these inorganic minerals, a process that is, not coincidentally, called mineralization. For all soil types – either the rich clay soils or the poor sandy soils – humus is the most important source of nitrogen and phosphate compounds. Dr. Goode goes on to say that when we use descriptors like “leather” or “cherry” to describe a wine’s aromas, we don’t assume that the actual liquid contains such substances. Although some wine writers, winegrowers and wine sellers would like to make you believe otherwise, there is no direct link known between the soil minerals and the earthy, “mineral”, aromas in the wine. Wine tasting notes (even by professionals) echo this assumption. Terroir provides stress, and that you can taste. If there was one aspect that stands out as the commonly known pen to paper definition of terroir, it would be soil. production of quality wine, but is often permitted outside of Europe. Terroir definition is - the combination of factors including soil, climate, and sunlight that gives wine grapes their distinctive character. Terroir in Wine — Somewhereness “No other major civilization in Europe or elsewhere has ever valued the soil more than the French or associated it more intimately with the good.” A wine with a goût de terroir (flavour of terroir) was a shoddily made wine that tasted of unripe or rotten grapes.
