Azienda Agricola Frank Cornelissen

Belgian-born winemaker farming 24 hectares of old alberello and row-trained vines on the northeastern slopes of Mount Etna, making red and white wine from indigenous Sicilian varieties under a strict non-intervention philosophy since 2001.

The producer

Frank Cornelissen arrived on the slopes of Mount Etna in 2000 with a career in wine behind him and no vines in front of him. He had spent years as a Belgian merchant selecting and trading exceptional bottles before concluding that the choosing was not enough. One year after arriving he registered the estate under his own name, unusual on Etna where most producers anchor their name to a place rather than a person.

The winery sits on the northeastern flank of the volcano with 24 hectares under vine: 13 hectares of old alberello parcels, the traditional free-standing bush-vine system, and 9 hectares of old vines retrained into modern rows. Elevations run from 600 to 1,000 metres, high enough to cool the growing season and push harvest to mid-October or later. Cornelissen rejects all treatments, chemical, organic, and biodynamic alike, ferments with native yeasts, and ages Susucaru Rosso through two months of skin maceration in fiberglass. His own account of the shift: the wines began as an assertion of winemaker intent and over time became less about him and more about Etna.

Notable facts

The story

From Trading to Farming

Frank Cornelissen had spent years selecting and trading exceptional wine before he drove to Sicily and climbed a volcano. He arrived on the slopes of Mount Etna in 2000, not yet with a winery or a vineyard, just with the idea that growing was more interesting than choosing. He spent a year on the mountain before committing to anything official. Then in 2001 he registered the estate under his own name, which was itself an unusual choice on Etna, where most producers name their domaines after a place rather than a person. The decision carried a specific weight: it meant the wine could not be explained by a hill or a village. It had to be explained by the person who chose to come here, and by the mountain that persuaded him to stay.

The Producer

Frank Cornelissen arrived on the slopes of Mount Etna in 2000 with no winery and no vines, just a conviction that the most interesting thing he could do with a career in wine was grow it rather than trade it. He had spent years as a Belgian merchant working with exceptional bottles before concluding that the volcano was where he wanted to be. One year after arriving he formally registered the estate.

That gap matters. Cornelissen farmed the mountain for a full year before he committed to the name, and the name he chose was his own, which is unusual on Etna where most producers anchor their name to a place. The winery sits on the northeastern flank of the volcano with 24 hectares under vine: 13 hectares of old alberello parcels, the traditional free-standing bush-vine system that has shaped Etna farming for centuries, and 9 hectares of old vines retrained into modern rows. He makes red and white wine from indigenous Sicilian varieties under a philosophy that rejects chemical, organic, and biodynamic treatments alike.

Place

Mount Etna is an active volcano on the northeastern coast of Sicily. The northeastern flank where Cornelissen farms sits at elevations between 600 and 1,000 metres, high enough to cool what would otherwise be a hot Mediterranean growing season significantly. That cooling stretches ripening across months and pushes harvest to mid-October or early November, late by Sicilian standards and late enough that Cornelissen can wait for phenolic ripeness without the grapes baking in summer heat.

The elevation shapes the wines directly. Nerello Mascalese grown at altitude on volcanic soils keeps acidity that the same grape loses on lower, warmer ground. The longer growing season builds flavour complexity without surrendering freshness. Wines from this part of Etna tend toward pale colour, firm acidity, and lifted aromatics, qualities that come from the altitude and the volcanic mineral character of the soils rather than from cellar intervention.

Soil And Site

The soils in the Susucaru parcels are volcanic basalt, lava, and sand. Basalt and lava are porous and drain freely, which stresses the vines and concentrates the grapes. Sandy volcanic soils also resist the phylloxera louse that devastated most European vineyards in the late nineteenth century, which means many of Etna's oldest plots still grow on their original roots. The alberello training system is a direct consequence of the terrain: on steep volcanic slopes with no irrigation and low fertility, the low bush form reduces the vine's surface area, limits yield naturally, and forces roots deep into the mountain.

At yield targets of 300 to 600 grams per vine for the top parcels, each vine produces roughly the weight of a single bunch. Harvest runs in multiple passes between mid-October and early November as different plots and vine ages reach ripeness at different times.

Story

Cornelissen came to Etna from a world of carefully selected, carefully traded exceptional wine. The transition from merchant to grower was a deliberate rejection of that position: he had spent years choosing what other people grew and decided the choosing was not enough.

The early wines were built around his intent. He had a winemaker's idea of what Etna could produce and applied it. Over the years the approach shifted. In his own words, slowly the fruit took over. The wines became less about him and more about the volcano. That shift is not a marketing position. It is documented in how the cellar works: no sulphur, no additives, no treatments of any kind, spontaneous fermentation initiated by native yeasts from the vineyard, and extended skin maceration in fiberglass tanks. The technology the estate uses is chosen practically rather than avoided on principle. Cornelissen has said he is logical, that using technology is not wrong, and that its use makes a difference. Fiberglass preserves temperature and is neutral; oak would add flavour he does not want.

The philosophical arc from winemaker-led to terroir-led is now the foundation of everything the estate does.

Vineyards And Cellar

The alberello parcels are farmed without machines. The low bush-vine form on steep volcanic slopes makes mechanical harvesting impossible, so every vine is handled individually. The harvest decision follows phenolic ripeness rather than a calendar date, which is why picking runs across several weeks in multiple passes. At 300 to 600 grams per vine, the top vineyard yields are a fraction of what conventional viticulture targets.

In the cellar, Susucaru Rosso is fermented with a pied de cuve, a small quantity of actively fermenting juice used to start spontaneous fermentation in the main tank. After that starter takes hold, fermentation and skin maceration continue together in fiberglass for approximately two months. The long skin contact extracts colour, tannin, and the aromatic compounds from the grape skins. No oak is used. No additives enter the wine at any stage. Susucaru Rosso has character from the grapes and the volcanic soils rather than from cellar flavour additions.

Wines

Cornelissen's range runs across three tiers. Susucaru is the entry level, blended across parcels, available in red and white. Munjebel is the mid-tier range, also covering both colours. Magma is the single-vineyard top tier.

Susucaru Rosso blends five varieties: Nerello Mascalese, Nerello Cappuccio, Minella Nera, Alicante Bouschet, and Minella Bianca. The five-variety blend is unusual. Nerello Mascalese provides the backbone, its pale colour, firm acidity, and red fruit character typical of Etna's best reds. Nerello Cappuccio deepens colour and softens tannin. The three remaining varieties, including the white Minella Bianca, add aromatic complexity and contribute to the wine's particular freshness. After two months of skin maceration the wine has texture and extract without heaviness.

Munjebel Bianco Classico is a 50/50 blend of Grecanico Dorato and Carricante. Both are indigenous white varieties; Carricante in particular is known for its high acidity and mineral character on Etna. The equal-parts blend at altitude produces a white wine with the kind of taut acid line that allows for ageing.

Magma sits at the top of the range as a single-vineyard wine, though the verified material does not confirm specific parcel details beyond the tier name.

In The Glass

Susucaru Rosso rises from the glass with red and dark fruit, cherry and wild raspberry, and a thread of smoky mineral character that comes directly from the volcanic basalt and lava soils. Alongside the fruit there are herb and spice notes: thyme, pepper, blood orange peel. The two months of skin maceration give the wine texture and grip, a firm but not heavy tannin feel that comes from the Nerello varieties rather than from oak. Acidity is bright and sustaining. On the finish the smoky mineral quality lingers alongside the red fruit, and the wine holds its freshness to the end.

Munjebel Bianco Classico shows what the altitude and the Carricante grape can do with acidity.

Across the range the volcanic origin is present in every bottle. The smoke, the mineral edge, and the freshness at altitude are not manufactured qualities. They come from where the vines grow.

A Bottle To Understand It

Start with Susucaru Rosso. It is the most widely available wine in the range and the one with the clearest view of the estate's approach: five indigenous varieties from volcanic soils, two months of skin maceration in fiberglass, no oak, no additives. In the glass it is pale for a red wine, with firm acidity, cherry and wild raspberry fruit, smoky mineral lift, and herb and spice notes from the blend. The tannins are real but not aggressive. The finish is long and mineral. Susucaru Rosso blends five varieties and spends two months on its skins in fiberglass.

Anecdote

Frank Cornelissen had spent years selecting and trading exceptional wine before he drove to Sicily and climbed a volcano. He arrived on the slopes of Mount Etna in 2000, not yet with a winery or a vineyard, just with the idea that growing was more interesting than choosing. He spent a year on the mountain before he committed to anything official. Then in 2001 he registered the estate under his own name, which was itself an unusual choice on Etna, where most producers name their domaines after a place rather than a person. The decision to use his own name carried a specific weight: it meant the wine could not be explained by a hill or a village. It had to be explained by the person who chose to come here, and by the mountain that persuaded him to stay.

Final Word

Cornelissen's winery began as one man's attempt to grow on one of Europe's most demanding volcanic terroirs. Over two decades it became something closer to a document of the mountain itself. The wines are not easy to categorise, which is the point. They come from a Belgian merchant who walked away from trading, climbed an active volcano, and planted his name on the label.
