Which grape variety is characterized by a thick skin and high tannins, making it suitable for aging?

Mourvèdre is known for its thick skin and high tannin content, which are key characteristics that contribute to its suitability for aging. The thick skin of Mourvèdre allows it to withstand various environmental stresses, including pests and diseases, leading to grapes that can achieve a higher concentration of flavor and color. This thicker skin also results in wines with a robust structure and tannic backbone, essential for longevity in the bottle.

As wines made from Mourvèdre age, they develop complex flavors and aromas, often transitioning from fruity and youthful characteristics to more intricate notes of earthiness, spice, and savory elements. This evolution during the aging process makes it a preferred choice for winemakers aiming to produce wines that can mature beautifully over time.

In comparison, Pinot Noir, while elegant and aromatic, has a thinner skin that generally results in lighter tannins and is typically enjoyed younger. Grenache, while also rich and fruit-forward, offers lower tannin levels and is often blended to enhance its aging potential rather than being aged on its own. Carmenere has its own distinctive profile and can have a moderate structure, but it doesn't possess the same level of tannic strength and aging capability as Mourvèdre.
