Trentino–Alto Adige / Südtirol
Trentino–Alto Adige is Italy’s northernmost wine region and one of Europe’s most important areas for high-altitude viticulture. It produces precise aromatic whites, elegant Alpine reds, and outstanding traditional-method sparkling wines. Though grouped administratively, Trentino (Italian-speaking) and Alto Adige/Südtirol (majority German-speaking) are culturally and viticulturally distinct.
1. Regional Identity
Alto Adige / Südtirol
- Mountainous, steep vineyards (250–900+ m).
- Germanic heritage; strong cooperative culture (Terlano, Tramin, Girlan).
- Leading varieties: Pinot Noir (Blauburgunder), Sauvignon Blanc, Gewürztraminer, Kerner, Riesling, Schiava, Lagrein.
- Emphasis on purity, precision, and site definition.
Trentino
- Broader valley floors; larger-scale production.
- Key strengths: Teroldego, Nosiola, and Trento DOC sparkling.
- Mix of large cooperatives (Cavit, Mezzacorona) and high-quality independents (Foradori, Pojer e Sandri).
2. Climate & Terroir
Climate
- Alpine continental: hot, dry summers; cold winters; wide diurnal swings.
- Föhn winds reduce disease pressure and accelerate ripening.
- Altitude preserves acidity and aromatics.
- Harvest windows range from late August (early whites) to early October (Teroldego).
Soils
- Porphyry (Valle Isarco, Cembra) → mineral whites, crisp Riesling/Kerner.
- Dolomitic limestone → finesse in Pinot Noir, Sauvignon Blanc.
- Morainic deposits → ideal for Trento DOC Chardonnay.
- Alluvial gravels → Teroldego, Lagrein on warmer sites.

| Cembra Valley | MT, Riesling | Porphyry terraces | Pojer e Sandri, Zanotelli | 9–11 t/ha | Sept | High-altitude aromatics |
5. Winemaking Techniques
Whites
- Fermentation: stainless steel for purity; neutral oak for Chardonnay/Pinot Bianco; 12–16°C for aromatics.
- Lees work: essential for Trento DOC; common in structured Alto Adige whites.
- Skin contact: short, selective use (Gewürztraminer, Nosiola).
- Oxidation control: tight SO₂ and inerting to preserve Alpine freshness.
Reds
- Pinot Noir: partial whole cluster, gentle extraction, 12–15 day maceration, medium-toast tonneaux or large oak.
- Schiava: typically whole-berry, minimal extraction, designed for delicacy.
- Lagrein: short to medium maceration, some barrique for structure.
- Teroldego: stainless + large oak, occasional amphora; medium maceration for structure without bitterness.
Sparkling (Trento DOC)
- Base wine from early-picked Chardonnay/Pinot Noir.
- Whole-bunch pressing; fermentation in steel or large oak.
- Secondary fermentation in bottle; long lees ageing (30–90+ months).
- Character: linear, mineral, fine mousse, Alpine acidity.
6. Viticultural Challenges
- Steep terraces restrict mechanisation.
- Sunburn risk for Gewürztraminer and Pinot Noir in hot vintages.
- Hydric stress on low-retention porphyry slopes.
- Ripeness balance: too early = harsh acidity; too late = loss of mountain precision.
- Mildew spikes after summer storms despite overall lower disease pressure.
7. Key Producers

Terlano, Cantina Tramin, Hofstätter, Girlan, Tiefenbrunner, Nals Margreid, Köfererhof, Kuenhof, Gumphof.
