Grenache, also known as Garnacha, is a classic Mediterranean grape variety, with a long history of cultivation. It is one of the most widely grown red grape varieties in the world, and is a major component in many of the most famous wines of Spain and France.

Grenache is a medium-sized, dark-skinned grape variety with a relativelly thin skin. Grenache wines have a relatively light ruby-red colour, with a full, spicy and fruity character. Aromas of red fruits, dark berries and pepper are common, and on the palate, Grenache wines tend to have a soft, velvety texture and a subtle sweetness.

Grenache is most commonly planted in the Mediterranean, particularly in Spain, France and Italy. In Spain, it is one of the most widely planted red varieties, and is commonly found in Rioja wines together with Tempranillo. In France, it is a major component of the classic Rhône blends, and is also found in Provence and Languedoc-Roussillon. In Italy, Grenache is grown particularly in Sardinia where it is called "Cannonau". Grenache is a vigorous variety, and needs plenty of sunshine and warm temperatures to ripen well. It is drought-resistant, and can tolerate high yields, but too-high yields can lead to diluted and thin wines. Grenache is often blended with other varieties to add structure and body. Grenache is a highly versatile variety, and is used to make a wide range of styles. In Spain, it is used to make full-bodied Riojas but also fruity rosé wines. In the Rhône, Grenache is a major component of the classic Châteauneuf-du-Pape blends. In Provence, Grenache is used to make the famous rosé wines. Grenache-based wines are often full-bodied and fruity, so they are best served with rich, hearty dishes such as roast meats, game and stews. They also pair well with mild cheeses and tomato-based sauces.

Grenache is one of the oldest grape varieties in the world, with a history of cultivation going back to the 1st century BC.

It was likely brought to Spain by the Phoenicians.
