Chapter 26: Introduction to Italy, The Vine

Why Italy Is So Complex

Italy’s wine complexity comes from three intersecting factors:

1. Extreme Geographic Diversity

Italy stretches over 1,000 km from the Alpine border with Austria in the north to the Mediterranean island of Pantelleria, which is closer to Africa than to Rome. This span creates an enormous range of climates:

Alpine north (Trentino-Alto Adige, Valle d’Aosta): Cool, high altitude, influenced by mountain air. Produces crisp, aromatic whites and elegant light reds.
Continental north (Piedmont, Veneto, Friuli): Cold winters, warm summers, significant fog. Home to Nebbiolo, Corvina, and Pinot Grigio.
Central Italy (Tuscany, Umbria, Marche): Mediterranean with continental influence. Rolling hills, warm summers. Sangiovese country.
Southern Italy and islands (Campania, Puglia, Sicily, Sardinia): Hot Mediterranean to semi-arid. Indigenous heat-loving varieties: Aglianico, Primitivo, Nero d’Avola.

2. Hundreds of Indigenous Grape Varieties

Italy has more indigenous (autochthonous) grape varieties in commercial use than any other country, estimates range from 350 to over 500. While France built its reputation on a handful of grapes that spread globally (Cabernet Sauvignon, Chardonnay, Pinot Noir), Italy’s grape heritage stayed local. Nebbiolo is found only in Piedmont and Lombardy. Sangiovese dominates Tuscany but barely exists elsewhere. Aglianico thrives in Campania and Basilicata but is rare outside southern Italy.

This means Italian wines are usually identified by region (or appellation) rather than by grape variety. When you see “Barolo” on a label, you’re expected to know it’s 100% Nebbiolo. When you see “Chianti Classico,” you’re expected to know it’s predominantly Sangiovese.

3. A Deep Winemaking Culture with Regional Identity

Italian wine culture is intensely local. Each region has its own traditions, grape varieties, food pairings, and production rules. A winemaker in Barolo has almost nothing in common with a winemaker in Sicily, even though both are “Italian.” This regionalism is a strength (incredible diversity) but also a challenge (steep learning curve).

The exam approach to Italy: WSET breaks Italy into three chapters: Introduction (this chapter, covering wine law and the big picture), Northern Italy (Chapter 27), and Central & Southern Italy (Chapter 28). The key to studying Italy is to learn the classification system first, then tackle each region knowing which grapes and appellations to focus on.

Italian Wine Law: The Classification System

Italian wine classification is one of the most tested topics for WSET L3 Italy questions. Understanding the pyramid is essential before diving into specific regions.

Italian Wine Classification (Base → Top)

Vino

Basic table wine. No geographic indication, no vintage required, no specific grape varieties mandated. The most basic category, roughly equivalent to France’s Vin de France.

IGT (Indicazione Geografica Tipica)

Regional wine with a geographic indication. More flexible than DOC/DOCG, allows a wider range of grapes and winemaking techniques. Many of Italy’s most famous “rebel” wines (like the original Super Tuscans) were classified as IGT because they didn’t fit within existing DOC rules. IGT does not mean low quality: some of Italy’s most expensive wines carry IGT labels.

DOC (Denominazione di Origine Controllata)

Controlled designation of origin. Wines must come from a defined area using specified grapes and production methods. Stricter than IGT: specific grape varieties, maximum yields, minimum ageing periods. Most established Italian wine regions have DOC status.

DOCG (Denominazione di Origine Controllata e Garantita)

The top tier. In addition to all DOC requirements, DOCG wines must pass a government tasting panel and carry a numbered seal on the bottle. Stricter production rules and lower maximum yields than DOC. Reserved for Italy’s most prestigious appellations: Barolo, Barbaresco, Brunello di Montalcino, Chianti Classico, Amarone, and others.

Exam Trap: IGT Can Be Premium

Don’t assume the pyramid means IGT is always below DOC/DOCG in quality. The most famous example is the Super Tuscans: wines like Sassicaia and Tignanello that used non-traditional grapes (Cabernet Sauvignon, Merlot) and couldn’t qualify for DOC status. They were labelled as humble Vino da Tavola (now IGT), despite being some of Italy’s greatest and most expensive wines. The classification tells you about regulatory compliance, not necessarily quality.

Understanding Italian Labels

Italian wine labels can be confusing because they follow different conventions depending on the region. Some key patterns:

Geographic Naming vs Varietal Naming

Most traditional Italian wines are named by place (geographic naming), not by grape:

Barolo = Nebbiolo (100%)
Chianti = Sangiovese (dominant)
Soave = Garganega (dominant)
Valpolicella = Corvina (dominant blend)
Amarone della Valpolicella = Corvina blend, dried grape method

However, some regions and styles use varietal naming:

Pinot Grigio delle Venezie DOC = Pinot Grigio from the Veneto area
Barbera d’Asti = Barbera grape from Asti
Moscato d’Asti = Moscato grape from Asti

Key Label Terms

Common Italian Label Terms

Classico

The original, historic heartland of an appellation. Wines from the Classico zone are typically considered the best sites. Example: Chianti Classico is a specific zone within the broader Chianti region, it was the original Chianti area, and its wines are generally higher quality.

Riserva

Longer ageing than the standard version, both in barrel and in total before release. Riserva wines should be more complex and concentrated. The specific ageing requirements vary by DOC/DOCG.

Superiore

Higher minimum alcohol and/or stricter production rules than the standard version. Usually indicates a step up in quality. Example: Valpolicella Superiore has higher alcohol and longer ageing than basic Valpolicella.

Vigna / Vigneto

Single vineyard. Indicates the wine comes from one named vineyard plot, suggesting site-specific quality.

Classico is not a quality designation, it’s geographic. A “Classico” wine comes from the original, historically defined core of the appellation. Over time, many appellations expanded their boundaries to include surrounding areas. The Classico zone marks the original, often hillside heartland where quality is generally highest. But a badly made Classico can still be worse than a well-made non-Classico.

Italy’s Indigenous (Autochthonous) Grapes

Italy’s greatest asset is its extraordinary collection of native grape varieties. The term autochthonous means “originating from the place where it is found”, these are grapes that evolved in Italy over millennia, adapted to local conditions, and were never widely exported.

Why So Many Native Grapes?

Geographic isolation: Italy’s mountainous terrain historically separated regions, allowing each area to develop its own grape varieties independently
Ancient viticulture: Grape growing has been practised in Italy for over 3,000 years, giving varieties time to adapt to local micro-climates
Cultural pride: Italian winemakers have historically valued local traditions over international fashion, preserving native varieties rather than replacing them with Cabernet Sauvignon or Chardonnay

The Most Important Native Grapes (Overview)

Key Italian Native Grapes by Region

Nebbiolo

Piedmont. Barolo, Barbaresco. High acid, high tannin, pale colour, tar and roses.

Barbera

Piedmont. High acid, low tannin, deep colour, cherry and plum.

Sangiovese

Tuscany. Chianti, Brunello di Montalcino. High acid, medium tannin, sour cherry, dried herbs.

Corvina

Veneto. Valpolicella, Amarone. Sour cherry, almond, can be dried for concentration.

Glera

Veneto. Prosecco. Light, fruity, pear/apple, tank-method sparkling.

Garganega

Veneto. Soave. Citrus, almond, light to medium body.

Aglianico

Campania/Basilicata. Taurasi, Aglianico del Vulture. High tannin, dark fruit, volcanic.

Nero d’Avola

Sicily. Plum, spice, chocolate. Full-bodied. Sicily’s signature red.

Verdicchio

Marche. Citrus, almond, mineral. Increasingly respected white.

Climate: From Alpine to Mediterranean

Italy’s north-to-south span creates a climate gradient that is key to understanding its wine diversity:

Zone	Climate	Key Regions	Wine Style
Far North	Alpine/Continental, cool, significant altitude	Trentino-Alto Adige, Valle d’Aosta	Crisp whites, aromatic varieties, light elegant reds
North-West	Continental, cold winters, warm summers, fog	Piedmont, Lombardy	Structured, tannic reds (Nebbiolo); sparkling (Moscato, Franciacorta)
North-East	Continental with Alpine influence	Veneto, Friuli	Dry whites (Pinot Grigio, Soave), Amarone, Prosecco
Central	Mediterranean with continental pockets	Tuscany, Umbria, Marche, Abruzzo	Medium to full reds (Sangiovese), rosso everyday wines
South & Islands	Hot Mediterranean to semi-arid	Campania, Puglia, Sicily, Sardinia	Full-bodied reds, heat-tolerant native varieties

Vine Training and Grape Growing

Italy uses a wide range of vine training systems, which is sometimes tested:

Pergola (tendone): Traditional in northern Italy (Trentino-Alto Adige, parts of Veneto). The vine canopy is trained high, with fruit hanging below a horizontal framework. This was historically used for high-yielding, heat-avoiding viticulture. Still used for Pinot Grigio and sparkling wine grapes, but increasingly replaced by VSP (Vertical Shoot Positioning) for quality wines.
Alberello (bush vine / gobelet): Traditional in southern Italy and the islands. Low, free-standing vines without a trellis. The bushes shade the grapes from intense sun and work well in hot, dry conditions with poor soils. Used for varieties like Nerello Mascalese on Etna, Primitivo in Puglia.
Guyot / VSP: Increasingly common for quality production across Italy. Better canopy management, improved airflow, more even ripening.

Overview of Italy’s Major Wine Regions

This is a high-level overview. Chapters 27 and 28 cover each region in depth.

Northern Italy (Chapter 27)

Piedmont: Barolo, Barbaresco (Nebbiolo), Barbera d’Asti, Moscato d’Asti. Italy’s greatest red wines.

Veneto: Valpolicella, Amarone (Corvina), Soave (Garganega), Prosecco (Glera). Italy’s largest volume region.

Trentino-Alto Adige: Cool-climate whites (Pinot Grigio, Gewürztraminer). Alpine influence.

Friuli-Venezia Giulia: Premium dry whites (Pinot Grigio, Sauvignon Blanc, Friulano). Italy’s best white wine region.

Central Italy (Chapter 28)

Tuscany: Chianti, Chianti Classico, Brunello di Montalcino, Vino Nobile di Montepulciano (all Sangiovese), Super Tuscans (Cabernet/Merlot blends).

Short Answer Strategy

When answering an Italian wine question, start by placing the wine in its classification (DOC/DOCG/IGT), then identify the region and climate, then the grape variety and style. This structure works for any Italian wine: “Barolo DOCG is made in the Piedmont region of north-west Italy, from 100% Nebbiolo grown in a continental climate with significant fog. The wines are full-bodied with high acid, high tannin…” and so on.
