A wine with a goût de terroir (flavour of terroir) was a shoddily made wine that tasted of unripe or rotten grapes. Soil chemical composition also influences the microbiotic ecosystem of the vineyard. result, the aromas mature faster, the grapes get higher sugar levels and the 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. Proper aeration of the soil stimulates soil life, and Due to its chemical and especially physical properties, it partly determines the ripening of the grapes and the development of fruity and vegetal aromas. influence on wine quality than the chemical composition of the soil2-4. Organic compounds – molecules derived from (dead) organisms – end up in the wine and come from the vineyard, or are produced by the yeast during alcoholic fermentation. growing season, just before the véraison, can be beneficial.

While the soil is a complicated one, it tends to be finely grained, drains well, retains and reflects heat, and holds water. Why does wine made with very similar winemaking techniques taste so different when originating from different terroir?

The importance of regional ties to the climate, soil and grape varieties is at the heart of terroir. Vine water status is a key factor in grape ripening and vintage quality for red Bordeaux wine. Methoxypyrazines are As popular as they have become, the concepts of soil and minerality in wine only seem to be prescribed to certain wines. How can it be assessed for vineyard management purposes? While rieslings from Mosel have a distinctive “tingling” sensation that we can only describe as slate minerality.
