Grenache Rosé Wine
Grenache (in Spanish, Garnacha, in Catalan, Garnatxa) is one of the most widely planted red wine grape varieties in the world.
It ripens late, so needs hot, dry conditions such as those found in Spain the south of France and California's San Joaquin... Valley.
It is generally spicy, berry-flavored and soft on the palate with a relatively high alcohol content, but it needs careful control of yields for best results. It tends to lack acid, tannin and color, and is usually blended with other varieties such as Syrah, Carignan and Cinsaut.
Grenache is the dominant variety in most Southern Rhône wines, especially in Châteauneuf-du-Pape where it is typically over 80% of the blend.
In Australia it is typically blended in "GSM" blends with Syrah and Mourvèdre.
Grenache is also used to make rosé wines in France and Spain, notably those of the Tavel district in the Côtes du Rhône. And the high sugar levels of Grenache have led to extensive use in fortified wines, including the red vins doux naturels of Roussillon such as Banyuls, and as the basis of most Australian "port".
Grenache is often used as a blending component, adding body and sweet fruitiness to a wine. The grape can be troublesome for the winemaker due to tendency to oxidize easily and lose color. To compensate for the grape's naturally low tannins and phenolic compounds, some producers will use excessively harsh pressing and hot fermentation with stems to extract the maximal amount of color and phenols from the skins. This can backfire to produce green, herbaceous flavors and coarse, astringent wine lacking the grape's characteristic vibrant, fruitiness. To maintains those character traits, Grenache responds best to a long, slow fermentation at cooler temperatures followed by an maceration period. To curb against oxidation, the wine should be racked as little as possible. The use of new oak barrels can help with retaining color and preventing oxidation but too much oak influence can cover up the fruitiness of Grenache.
The high levels of sugars and lack of harsh tannins, makes Grenache well adapted to the production of fortified wines, such as the vin doux naturels (VDN) of the Roussillon region and the "port-style" wines of Australia. In these wines, the must ferments for 3 days before grape spirit is added to the must to halt the fermentation and the conversion of sugar into alcohol. The high alcoholic proof grape spirit brings the finish wine up to 15-16% alcohol. These wines can be made in a rancio style by leaving it outside in glass demi-johns (or car boys) or wooden barrels where the wine bakes in the sun for several years until it develops a maderized character and flavors of sour raisins, nuts and cheese. These fortified VDNs and port-style wines have longevity and can be drinkable well into their third decade.
Alcohol abuse can be dangerous.
