Garnacha is often used as a blending component, adding body and fruit sweetness to wine, although wines made from this strain can differ greatly in their flavours depending on their production region.
This grape can give the producer some problems due to the tendency to oxidise easily and lose colour, as well as its tedious harvesting as its strong stem makes harvesting with a combine difficult.
The high levels of sugars and scarce tannins make Garnacha well suited to the production of fortified wines, such as the vin deux naturelle of Roussillon and the port-style wines of Australia.
In the Rioja region, it is often blended with other varieties such as Tempranillo and Graciano. Garnacha wines in Rioja tend to be smooth, fruity and balanced, with a good capacity for ageing in oak barrels.
On the other hand, in Priorat, one of the most prestigious appellations in Catalonia, Grenache is grown on slate soils, which provide a unique minerality to the wine, and the vineyards, often old and low-yielding, produce grapes of great concentration, so they are usually powerful, with notes of ripe fruit, dried herbs and minerals, and have excellent aging capacity.
In France, especially in the Rhône, Grenache is one of the main blending grapes in Rhône Valley wines, such as Côtes du Rhône and Châteauneuf-du-Pape. In these wines, Grenache is combined with other indigenous Rhône varieties, such as Syrah and Mourvèdre, to create wines with remarkable aromatic complexity, ranging from red fruits and spices to notes of leather, earth and aromatic herbs.
However, in Australia and New World vineyards, they tend to be more intense and mature in their flavours, with notes of red and black fruits, as well as sweet spices and a slight hint of pepper.
