Grenache: In-Depth Grape Varietal Profile

A Grenache Definition

Have you ever wondered what is garnache? Well Grenache grapes, also known as Garnacha grapes in Spain or Garnache, are renowned for their pivotal role in the world of viticulture. Originating most likely in the northern province of Aragon, Spain, Grenache has become one of the most widely planted red grape varietals globally. Its significant presence in the Rhone Valley of southern France further underscores its importance. But, being such a widely cultivated variety, it is necessary to keep something in mind: if the crops are not managed with care, these European grapes can give yields that are too high. And that, as we know, is likely to result in an inexpensive wine.

Characterized by a relatively low pigment and malic acid content, Grenache grapes tend to oxidize readily. This feature, along with its thin skin and lack of colouring phenolic compounds, makes Grenache particularly suitable for producing pale rosé wines. Grenache grapes are also used to make sweet fortified wines, like the vin doux of Roussillon.

• Cultivation: In terms of land dedicated to a single grape variety, Grenache holds a significant position, surpassing even well-known grape varieties like Cabernet Sauvignon and Chardonnay. This is largely due to extensive vineyards in northern Spain, where Garnacha is a staple table wine.
• Blend Component: although most consumed as varietal wines, Grenache grapes are also a key component in some of the most luxurious and expensive wines, such as those from the Châteauneuf-du-Pape AOC or the Rhone blends, with grapes like Syrah, Mourvèdre, and Viognier. Its ability to enhance the performance of other wine grapes in blended wines is well recognized.

• Global Travels: While Grenache is a native grape of Spain, its journey has been quite extensive, finding a significant place in the Languedoc-Roussillon region of France before becoming prominent in the southern Rhône.
• High Alcohol Content: Due to its long growing season, Grenache typically produces wine with a higher alcohol content, often hovering around 15%.
• Unexpected Places: Grenache vines have been cultivated in some unique locations around the globe, including countries like Algeria, Tunisia, and China.
• Diversity in Wine: from a dry to a sweet wine style, there is most likely at least 1 Grenache wine that fits your palate. For this reason, Grenache can be served with a wide range of food pairings

Viticultural Conditions and Influence of Terroir in Grenache Grapes

Grenache thrives in specific viticultural conditions that contribute significantly to their growth and the wines' characteristics.

Ideal Viticultural Conditions for Grenache Grapes

• Soil Types: Grenache prefers hot, dry soils that are well-drained. It is relatively adaptable to various soil types, but it particularly thrives in schist, granite, stony soil with heat-retentive stones and crumbly schist soil in regions like Priorat.
• Temperature Range: Grenache requires a warm climate, ideally in regions where it can receive ample sunlight and heat. The grape is known for its ability to withstand hot and dry conditions.
• Rainfall: The Grenache grape's adaptability to varying water conditions is highlighted by its average rainfall requirements. In the Rhône Valley, a region renowned for its Grenache wines, the average annual rainfall is around 120 mm. In contrast, the Priorat region, another key area for Grenache cultivation, receives between 400-600 mm of rainfall annually. This range demonstrates the grape's ability to thrive in environments with varied water availability bolstered by its inherent drought resistance.
• Growing Degree Days (GDD): Grenache typically requires an average of 1693 GDD. This figure underscores the grape's need for a warm climate and a long growing season. Being one of the last grapes to be harvested, Grenache's high GDD requirement is reflective of its need for extended periods of warmth and sunlight to reach full ripeness, crucial for developing its characteristic flavours and high sugar content.
• Altitude Influence: Altitude can influence the temperature and sunlight exposure the vines receive, impacting the ripening process and flavour profile of the grapes. For this reason, this grape is planted at high altitudes in regions such as the Ebro Valley.

Influence on Grape Characteristics

The characteristics of Grenache grapes are significantly influenced by the conditions in which they are grown. The grape's resilience in hot and dry climates plays a crucial role in the development of its high sugar levels. This often results in wines with a substantial alcohol content, typically reaching or exceeding 15% ABV.

Additionally, Grenache's preference for certain soil types, particularly schist and granite, notably impacts its flavour profile. These soil conditions contribute to the complexity and depth of the flavours in the wines produced from these grapes.

Moreover, in areas like Priorat, where Grenache vines are not excessively irrigated, the grapes tend to develop a higher concentration of phenolic compounds. This leads to the production of darker, more tannic wines, showcasing how vineyard practices and terroir intricately shape the qualities of Grenache wines.
