Grenache

photo of Grenache by Tim Ramey.Grenache noir is the world's most widely planted grape used to make red wine, sometimes bottled as a single unblended red variety, frequently as a rosé, but most often as the backbone of red blends.

Used as a component in some Northern Rhône reds, nearly exclusively for Rhône rosés and as the primary component in nearly all Southern Rhône red blends, Grenache is probably most notable as the base variety for Chateauneuf du Pape, Cotes du Rhône and Gigondas. In spite of its fame coming from these French AOCs, Spain is most likely this grape's origin1.

Grenache is known by local names (alicante, carignane rousse) in the Mediterranean regions of France. Particularly important in the areas of the Languedoc and Rousillon, there are also variants with different colored berries: white grenache blanc, and pink grenache rose or grenache gris. Nearly three times as much grenache is planted in Spain as in France. The spanish know this grape and wine as garnacha or garnacha tinta, where it is the dominant red wine variety in Catalonia and prominent in Rioja.2 Grenache leaf photo. The grape is known in Italy as cannonau.

In the New World, Australia has extensive plantings of Grenache and has been very successful making full-bodied Grenache-dominated red blends. Until surpassed by plantings of merlot in the past decade, Grenache was the third most planted red variety in California after Zinfandel and Cabernet Sauvignon. Most of this acreage is in the Central Valley and used to produce bulk rather than premium wine.

An abundant producer of fruit, grenache habitually will "alternate" a crop of 8 to 10 tons per acre one year and 14 to 16 tons the next. The vine is very sturdy and woody, lends itself well to head or spur pruning, and survives arid and drought conditions better than less vigorous vines. Rootstocks with low vigor can markedly increase fruit quality. A long, warm growing season is necessary, as Grenache tends to ripen late. Cool and damp conditions can cause "deadarm" disease in grenache, however, and its compact and well-filled clusters are quite prone to rot. Grenache is also susceptible to shatter or coulure.

Grenache cluster.The grenache grape is relatively low in both pigment and malic acid, and oxidizes readily. Although some 100% varietal wines are produced from grenache, particularly in Spain's Rioja and from some "old vines" plantings in California, it is mostly used to "fill out" red blends and soften harsher partners, such as syrah and carignan. Prior to the establishment of France's AOC, Burgundy's "dirty little secret" was that Grenache, grown in the Rhône Valley, often contributed flavorful appeal to save the sometimes thin and weak Pinot Noir.

On its own, grenache can make fleshy, heady wines with lots of fruit appeal in their youth. They tend to age rapidly, however, showing tawny colors and prone to oxidation or maderization after only a relatively short time in bottle. The general character and mouthfeel of Grenache wines are more distinctive and identifyable than any particular aromas or flavors.

*Typical Grenache Smell and/or Flavor Descriptors
*Typicity depends upon individual tasting ability and experience and is also affected by terroir and seasonal conditions, as well as viticultural and enological techniques. This list therefore is merely suggestive and neither comprehensive nor exclusive.

Varietal Aromas/Flavors:

Processing Bouquets/Flavors:

Mouthfeel: fleshy, full

Terroir: (varies)

Fruit: blackberry, black currant

Light Oak: vanilla, sweet wood

Spice: allspice, cinnamon

Heavy Oak: toast, oak, smoke

Floral: orange blossom

Bottle Age: (atypical)

Partly due to its commonplace abundance and partly due to its hardiness in warmer climates that are generally considered to grow lesser-quality wines, Grenache has never achieved as much of a premium reputation as other red varieties. The group of California wineries marketing themselves as the Rhône Rangers are committed to raising both the quality and profile of this and other lesser-known grape varieties.

 NOTES
1. The Italian island of Sardinia, grows the same grape variety as cannonau, and would argue that Spain garnished garnacha during the isle's four centuries of Spanish occupation.

2. Prior to 1970, Grenache made up about 2/3 of vineyards, dominating the Rioja; since, the dramatic spread of Tempranillo now accounts for 85% of all Rioja red production. RETURN
