How Amarone Is Made: The Appassimento Process

There is a smell I have been carrying around since October, since the afternoon I stood in a drying loft above the valley of Fumane with the windows open to the Lessini wind and a hundred racks of Corvina spread out before me in the half-dark: sweet and slightly ferrous, something between a ripe plum and a memory of leather, the smell of fruit in the middle of its second life. I am writing this in February in Lyon, where the light is grey and flat and the street below my window is slicked with cold rain, and I keep returning to that smell the way you return to a photograph you cannot stop looking at. It is the smell of appassimento. It is, in the most literal sense possible, the smell of Amarone being born.

Most wine begins in a vineyard and ends in a barrel. Amarone begins in a vineyard, passes through a building, and only then arrives at a barrel, and it is that middle passage, those ninety to a hundred and ten days on the racks, that makes it unlike anything else in Italy. The appassimento is not a winemaking technique applied after the fact, a finishing touch or a cellar trick. It is the wine's essential biography. Without it, there is no Amarone, only Valpolicella, which is a fine wine and an entirely different one.

The Architecture of Waiting

The building where this transformation happens is called a fruttaio, and the good ones have been standing in the hills of the Valpolicella Classico zone for long enough that no one is entirely sure who designed the original. What they share is a logic: high ceilings, opposing windows, stone walls thick enough to hold the temperature steady, and an orientation that catches the cold drafts descending from the mountains to the north when October arrives and the autumn heat begins to withdraw. Paolo Cottini's fruttai sit in the Classico heartland, in the villages and hillsides of Fumane and Negrar and Marano, and in autumn they smell like that photograph I cannot stop looking at.

The racks inside, called arele, were traditionally woven from bamboo or river reed, spaced just wide enough for air to move between the clusters laid across them. The clusters themselves are selected by hand at harvest in late September, the best of what the vine gave, loose-structured and thick-skinned, placed in single layers so that nothing touches, so that air is everywhere and nowhere is sealed against the drying. Every morning through October and November and into December, someone walks the rows, checking for the grey fuzz of Botrytis cinerea, removing any compromised berry before it infects its neighbor. It is slow, repetitive, essential work, the kind that does not produce anything visible on any given day but whose accumulated effect is the difference between a great Amarone and a lost one.

Three Grapes and the Thousand Years That Made Them

Not every grape survives a hundred days of controlled dehydration. The varieties that Valpolicella has grown for centuries were, in effect, selected over that time for exactly this quality: the ability to lose half their weight without losing their structure. Corvina is the backbone, fifty-five percent of the Cottini blend and the backbone of every serious Amarone in the Classico zone, and it carries the qualities that make appassimento possible: thick skins that resist rot, a naturally loose cluster that lets air circulate between berries, high natural acidity that does not evaporate away in the drying loft the way a more delicate variety's might. It is the grape that gives Amarone its particular bitter-cherry signature, the nervy tension that keeps the wine from becoming merely heavy, the persistence that is still on your palate twenty minutes after the glass is empty.

Corvinone occupies thirty-five percent of the blend, and while it was historically considered a clone of Corvina, modern ampelography has confirmed it as a distinct variety, larger-berried and even more resistant to the stresses of appassimento, contributing deep color and the broad, plush, glycerine-rich middle palate that keeps the wine from feeling austere. Rondinella is the remaining ten percent, the workhorse of the blend, more productive and lighter in character, there to add volume without redefining what the other two have already established.

The Valpolicella Classico zone, the original heartland of the appellation stretching across the valleys of Negrar, Fumane, Marano, and Sant'Ambrogio, produces the most concentrated fruit for appassimento precisely because its hillside parcels go into harvest already lean and structured, lower in water content than valley-floor grapes, their skins toughened by altitude and the calcareous and dolomitic soils that hold the warmth of the day and release it slowly through the night. Paolo Cottini farms six parcels across these valleys, from the 180-meter calcareous terraces at Camparsi in Fumane up to the 580-meter high ground at Ca' del Gallo in Negrar and Magine in Marano, and the altitude range is not incidental. It is what gives the wine its lift, its tension, the impression that something at the center of all that concentration is still alive and searching upward.

The training system throughout is Pergola Veronese, the traditional overhead pergola of the region, which shades clusters from direct summer sun, reduces heat stress on the skins, and keeps the fruit loose and well-ventilated on the vine. A grape grown tight and hot does not dry gracefully. A grape grown cool and loose, with air moving through the canopy, arrives at the fruttaio already knowing how to breathe.

What a Grape Becomes When Water Leaves It

I try to describe this to people who have not stood in a fruttaio in November and I never quite succeed, but here is the closest I have come: imagine that a grape is a message written in disappearing ink, and the drying is the process of making the ink visible. Everything that was dissolved or suspended in the berry's water, the sugars, the acids, the tannins, the aromatic compounds, the glycerine, the polyphenols in the skins, remains after the water has gone. By December, the cluster that weighed a kilogram in September weighs five hundred grams, sometimes less. The grape is dark and leathery, shrunken around its seeds, giving off that sweet-ferrous smell I associate with everything good about Veneto in autumn. Forty to fifty percent of the original weight has left through the walls of the berry, taken as vapor by the mountain wind, and what remains is more dense and more itself than anything you could coax from a fresh grape in a fermentation tank.

The chemistry is compounding and slow. As the malic acid metabolizes during drying, the wine's eventual harshness softens before fermentation even begins. The tartaric acid, the skeletal backbone of the wine, survives intact, and this is the paradox that makes Amarone possible: you end up with massive concentration and high alcohol sitting alongside a structural acidity that refuses to let the wine collapse under its own weight. The glycerine that accumulates gives the texture its characteristic silk-over-stone quality, neither fat nor sharp, and the aromatic transformation during those months of cellular respiration inside the drying berry shifts the fruit from fresh red cherry toward dried cherry, baked plum, dark spice, the faint camphor note that in my experience is one of Amarone's most reliable fingerprints, the thing I smell in the glass before I even know what I am about to taste.

December First

The DOCG regulations for Amarone della Valpolicella include a rule that strikes outsiders as peculiar until they understand what it is actually doing: no producer may begin fermentation before December 1st. This is not arbitrary bureaucracy. It is the legal guarantee that the appassimento has had time to work. A producer who cut the drying short by four or six weeks to gain an earlier harvest cycle or meet a tight bottling schedule would be producing a different wine under the same name, and the December rule prevents that, codifying the minimum duration into the appellation's identity. The most serious producers in the Classico zone extend well past the legal minimum, running the drying for ninety or a hundred or a hundred and ten days, because the extra weeks continue the concentration without diminishing the structural acids that will define the wine's behavior in the cellar over the following decade or two.

When December arrives, the clusters are destemmed and gently crushed, transferred to fermentation vessels, and left to work at sixteen to eighteen degrees Celsius for thirty-five days, a long and cool maceration that extracts color, tannin, and flavor from the concentrated skins without cooking off the aromatic precision that distinguishes the Classico zone from the broader appellation. After that, the wine moves to wood: twelve months in large three-thousand-liter Slavonian oak casks, then twelve months in French oak barriques, then twelve months in bottle. Approximately three years from harvest to table, and even then the wine is barely at its beginning.

The Same Process, Two Different Truths

Because appassimento is fundamentally an act of concentration, it amplifies what the growing season gave the grape rather than smoothing it out. A warm, generous year arrives at the fruttaio already rich in extract and sugar; the drying intensifies what is already there, and the resulting wine is structured and powerful and built for patience. A year with more acidity and lighter tannin produces a more elegant raw material, and the hundred days of drying concentrate that elegance alongside everything else, giving a wine that is leaner and brighter and more immediately approachable. This is why the 2017 and 2018 Paolo Cottini bottlings, made from the same vineyards by the same hands using the same process, are genuinely different wines and require different thinking at the table.

The 2017 was shaped by exceptional heat and severe spring frost that reduced yields early, producing small, concentrated berries with deep color and substantial tannin before a single cluster entered the drying room. By December, what the fruttaio had been given had become something monumental: black cherry, baked plum, dried blackberry, the warm sweet spice of fully ripe, fully dehydrated Corvina, a wine that sits at sixteen percent alcohol and carries the structure of something that will be a different wine in five years and a different wine again in ten. Open it with three hours of air, serve it alongside something braised and rich, and then set a bottle aside for 2035 and see what it has learned.

The 2018 followed irregular growing conditions that produced lighter tannin and lower anthocyanin content than the preceding vintage, and the fruttaio reflected that difference precisely. The same ninety-to-hundred-ten days of drying concentrated a more delicate raw material: red cherry and pomegranate rather than black fruit, herbal notes, a pronounced acidity that makes the wine more food-friendly and more approachable sooner. Where the 2017 asks for patience, the 2018 rewards the wine director who needs an Amarone that performs at the table tonight, alongside game birds or aged hard cheese, a wine that does not demand years of waiting before it says what it came to say.

Paolo Cottini and the Case for Smallness

There is no industrial Amarone from the Classico zone, not truly, but there is large-production Amarone, and it tastes different from what comes out of a small family operation whose six parcels span the full altitude range from Fumane to Negrar. The producer who manages his own fruttai, who walks the racks every morning himself, who knows by the smell of a given room whether the humidity is creeping up or the wind has dropped and the windows need opening, that producer is making decisions in October and November that no cellar technology can replicate. Cottini's six parcels range from the calcareous-dolomitic volcanic soils at Banchette to the high calcareous ground at Ca' del Gallo at five hundred and eighty meters, and they enter the blend not as homogenized bulk but as distinct voices, each contributing something the others cannot.

The family has grown grapes in Valpolicella for three or four generations. Paolo learned the craft from his father Silvano. The formal winery, Az. Agricola Paolo Cottini, was established in 2010 in Castelrotto, the medieval hilltop village in the heart of the Classico zone, and the scale has remained small enough that every decision in the fruttaio is a decision made by someone who knows the parcels by name and by the feel of the soil underfoot and by the way the Lessini wind moves through the valley in late October. That knowledge is in the glass. I can taste it in the 2017 and again in the 2018, two wines that share a process and a place and still manage to be entirely themselves.

Why the Name Means What It Means

Amarone means the great bitter one, a name that emerged to distinguish the fully fermented, dry wine from its sweet counterpart, Recioto della Valpolicella. Recioto is Amarone's ancestor, a wine made from the same appassimento process but with fermentation stopped early, before all the sugar converts to alcohol, so that the wine retains a lush sweetness that was historically what Valpolicella's hillside producers were known for. The story, which may be legend and may be true, holds that a barrel of Recioto was left unattended long enough to ferment past the point of sweetness, and the cellar worker who discovered it, expecting to find it spoiled, found instead something that tasted entirely different: dry, structured, tannic, profound. The name that attached to it was not a compliment, at first. The Italian palate of the time found the absence of sweetness unexpectedly bitter, a shock after Recioto's familiar warmth. The name survived as a description that became an identity. Modern Amarone is not bitter in any negative sense; it is rich and concentrated and complex and, when it comes from the right hillside and the right family and the right hundred days in a well-ventilated stone building above a valley in the Veneto, one of the most extraordinary things that a grape can become.

I think about that smell again as I write this, the sweet-ferrous air of the fruttaio in October, the Lessini wind moving through the windows, the racks in their rows in the half-dark. February in Lyon is a long way from that afternoon, but the bottle on my desk, the 2017, still carries it. Open it carefully, give it air, and wait. It will arrive.
