Though not a native Italian, the Belgian-born Cornelissen has lived around wine his entire life, growing up the son of an importer. Nearly 25 years ago, Frank invested in a vineyard high on the daunting slopes of Mount Etna in Sicily, starting with a mere 0.4 hectares of vines.
Now the proud owner of 19 hectares, the Cornelissen label has come to be known as a seal of not only quality, but impressively individual wines. While the early years brought wines of intense minrerality and acidity, Frank has grown along with his vineyards, learning through smart viticulture how to imbue more depth and richness into the wines that will always possess the clear minerality of such extreme sites.
Working with the indigenous grapes of Etna, such as Nerello Mascalese, can be daunting for many; many of the vineyards atop the mountain were planted with clones that would allow for impressive yields in place of high quality. Frank has used great clones, many un-grafted vines as well, to achieve the great quality he eternally pursues.
Stylistically, the wines are undoubtedly full of personality; he has separated his wines into "Grand Crus" and "Premier Crus," but will largely treat them the same, the difference being the vine material and quality of fruit. Grapes are de-stemmed and lightly crushed, and there will usually be some skin contact for all wines, whites included. Mascalese benefits from longer contact with the skins, usually around 50 days. The wines will ferment with native yeasts in large (1500-2500 L ) epoxy-lined tanks where they will age for 18 months. The wines will be bottled and again age in bottle for around 18 months before release. This does not account for the Perpetuum, which is a multi-vintage blend crafted as a perpetual reserve, or solera-style, dating back to the 2015 vintage.
Frank considers the Munjebel VA to be the most "Burgundian" in character - think of Nerello Mascalese as a bridge of sorts between Pinot and Nebbiolo - whereas the Munjebel CR is the most intense, structured version more in line with the grape's Nebbiolo character.
