When it comes to the grape variety Nebbiolo, its closest relatives were discovered through research conducted at the University of California-Davis and Istituto Agrario di San Michele all'Adige in 2004. The study revealed that Nebbiolo is related to the Piedmont region through two aromatic grape varieties – the Freisa grape of Piedmont and the Viognier grape from the Rhone region in France.
The connection between Nebbiolo and the Freisa grape of Piedmont is intriguing. Both grapes share similar characteristics and flavors, which suggests a close genetic relationship. As a sommelier, I have had the opportunity to taste wines made from both Nebbiolo and Freisa, and I can attest to the similarities in their profiles. Both grapes produce wines with intense aromas, high acidity, and firm tannins. These characteristics contribute to the age-worthiness and complexity of wines made from these grapes.
On the other hand, the discovery of a link between Nebbiolo and Viognier was unexpected. Viognier is a white grape variety known for its aromatic and floral characteristics. It is widely grown in the Rhone region of France and produces full-bodied and aromatic white wines. The connection between Nebbiolo and Viognier suggests that there might have been some historical cross-pollination between the two regions or the exchange of genetic material.
As a brewer, I find it fascinating to explore the genetic relationships between different grape varieties. Just like in the brewing world, where different strains of yeast can produce vastly different flavors and aromas, grape varieties also have their unique characteristics. Understanding the genetic connections between grape varieties helps us appreciate the diversity and complexity of wines.
It is worth noting that while Nebbiolo shares genetic similarities with Freisa and Viognier, it still maintains its distinct identity. Nebbiolo is known for its ability to produce some of Italy's most celebrated wines, such as Barolo and Barbaresco. These wines showcase the grape's characteristic flavors of red fruits, roses, and tar, along with its high acidity and firm tannins.
The research conducted in 2004 revealed that Nebbiolo is closely related to the Freisa grape of Piedmont and the Viognier grape from the Rhone region in France. These genetic connections help us understand the shared characteristics and flavors between these grape varieties. However, it is essential to appreciate Nebbiolo for its unique qualities and its ability to produce exceptional wines that are distinctively Piedmontese.
