Appassimento is the traditional drying method for Italian top wines like Amarone. Learn how this technique concentrates and refines wines.
Appassimento (Italian for "withering" or "drying") is a traditional Italian winemaking method in which grapes are dried for several weeks to months after harvest before being pressed and fermented. This process concentrates sugar, aromas, acidity, and extract in the berries, resulting in exceptionally powerful, complex wines.
After hand harvesting, grapes are spread on straw mats (Italian: "arele" or "graticci") or in shallow wooden crates in well-ventilated rooms. Historically, these were attics ("fruttai") with shutters or windows that allowed controlled air circulation.
The grapes typically lie there for 3-4 months (from October to January), sometimes even longer. During this time:
Temperature is ideally maintained at 5-15°C, humidity at 60-80%. Too dry, and the grapes shrivel too quickly; too humid, and rot threatens.
Many estates today use climate-controlled drying rooms with computer-managed temperature, humidity, and air circulation. This allows:
Despite modern technology, many top producers maintain the traditional method, preferring the more natural, complex aromas it yields.
The dramatic water loss concentrates all components:
During drying, complex biochemical processes occur:
The tannins, despite their concentration, often become softer and silkier, as the ripening of the berries during drying alters the phenolic structure. The high glycerol concentration gives the wine a creamy, oily texture.
The most famous and prestigious appassimento wine. After 3-4 months of drying, the grapes (mainly Corvina, Rondinella, and Corvinone) are fully fermented, resulting in a dry, powerful red wine with 15-17% alcohol.
Typical aromas: Dried plum, cherry compote, chocolate, tobacco, sweet spices, leather Aging potential: 10-30+ years
The "sweet sibling" of Amarone, also from dried grapes, but fermentation is stopped early, leaving residual sugar (8-12%). Intensely sweet, velvety smooth, perfect with chocolate desserts.
Typical aromas: Chocolate, dried figs, raisins, cherry compote, spice cake Alcohol: 12-14%
A clever hybrid method: young Valpolicella is passed over the still-warm pomace (skins and seeds) of freshly pressed Amarone and refermented. This adds additional aromas, extract, and alcohol — a kind of "appassimento light."
Character: More powerful than standard Valpolicella, but more approachable than Amarone Alcohol: 13-14.5%
From Lombardy, north of the Veneto. Made from Nebbiolo grapes (locally called "Chiavennasca"), which are dried using a similar process.
Character: Powerful, tannic, mineral, with notes of dried rose petals and tar Alcohol: 14-16%
Many Italian producers outside traditional areas experiment with the technique for IGT wines (Indicazione Geografica Tipica). Often only part of the grapes are dried and then blended with fresh must, allowing a subtler concentration.
The roots of appassimento reach back to Roman times. The ancient Romans already knew methods of grape drying for making sweet wines ("passum"). In the Veneto, the technique developed further in the Middle Ages, initially mainly for sweet Recioto wines.
The name "Amarone" only emerged in the 20th century — "amaro" means "bitter" — when a Recioto accidentally fermented completely and became dry. What began as a mistake became legend: the first documented Amarone dates from the 1930s, but it was only in the 1950s-60s that it was deliberately produced and gained international recognition.
Traditionally, appassimento wines were celebration wines — elaborate to produce, precious, and served only on special occasions. This tradition lives on: Amarone remains one of Italy's most exclusive and expensive wines.
The appassimento method is elaborate and risky:
These factors explain the high price of good Amarone wines — the effort is immense, the risk great.
Appassimento is not unique to Italy, but nowhere else has it been perfected to the same degree:
The key difference: appassimento not only concentrates sugar but preserves acidity and develops secondary aromas through the slow ripening during drying.
Appassimento is one of the most fascinating and elaborate techniques in winemaking. It transforms fresh grapes into concentrated, complex masterpieces with unique character. The resulting Amarone is not just a wine but an experience — powerful, elegant, complex, and with enormous aging potential.
Anyone who has enjoyed a well-aged Amarone understands why appassimento has fascinated the winemakers of the Veneto for centuries and delights wine lovers worldwide.
