Winepedia - Italian appellations explained. Episode 02: Südtirol/Alto Adige
Südtirol/Alto Adige is for many reasons one of the most fascinating regions in Southern Europe: it's where the German cultural sphere meets the Italian, where the mountains crack into fertile valleys, where the Mediterranean influences soothe Continental Climate.
Imagine a landscape of steep sun-kissed terraced slops, swept by brisk Alpine air, standing against snow-covered mountains, which not only serve as postcard-perfect backdrop, but also protect the vineyards from cold, damaging winds. The region is blessed with more than 300 days of sunshine, a wide day-night temperature range and an average growing season temperature of over 18° C, and sufficient precipitations, ideal conditions for growing high quality grapes.
QUALITY WINEMAKING ROOTED IN HISTORY
Archaeological excavations indicate the existence of viticulture could date back as far back as the Iron Age, proving this is one of the oldest wine producing regions in Europe. In 15 BC when the Romans first ventured into the region, they discovered locals storing wine in wooden vessels, while they themselves still used leather bags or amphorae. It continued throughout the Middle Ages and advanced thanks to the devoted care and industry of monasteries. Under the Hapsburg Empire, winegrowing in Alto Adige expanded, with the introduction of international varieties like Riesling and Burgundian grapes.
Today, there are around 5,000 winegrowers tending 5,300 ha of vineyards. Thirteen cooperative wineries produce almost 72% of the regionās wine. A typical cooperative will have several hundred members, each of whom individually cultivates a plot that, on average, is less than 2.5 acres..
The remaining 30% is produced by wine estates and independent winegrowers.
Even though it is one of Italyās smallest viticultural areas and represents less than 1% of total production, Alto Adige leads the country in quality with 98.8% of vineyards under DOC designation, quite a unique scenario, as the proportion is typically between 5% (Apuglia) and 40% (Piedmont).
The Alto Adige DOC, which covers the majority of wines made here, was granted in 1975 and is sub-divided to district and commune level, creating more than 30 possible provenance statements, each with Italian and German versions.
Discerning wine drinkers have recently rediscovered Südtirol/Alto Adige as a source of elegant and aromatic white wines, the type of wine which only the mixture of southern sun and crisp Alpine air can produce. The red wines, also much sought after because of their succulent fruit and velvety tannins are characterized by fruit rather than austerity.
Unique terroir, high quality wines, authentic varietal character.
The geological composition of Alto Adigeās winegrowing area is a broad spectrum of soils often varying from one vineyard to another. On the many slopes and terraces, moraine deposits predominate, and soil content ranges from volcanic porphyry (in Merano, Bolzano, and Kaltern) to weathered primitive rock soils composed of quartz and mica (the Isarco Valley) to limestone and dolomite (the Bassa Atesina) to sandy marl (south of Kurtatsch), offering just the right underlayer to each grape variety.
The different vineyard altitudes also provides a mosaic of microclimates. The Alps protect the region from inclement weather from the north, leaving the central valleys open towards the south and the Mediterranean. The Adige Valley has an extremely warm climate considering its latitude. However, the āOra,ā a dry, cooling wind from Lake Garda, tempers the hot summer days.
Hence, producers grow an extensive range of grapes, more than 20 in total: in addition to the indigenous varieties of Lagrein and Vernatsch, the key wine grapes used in Alto Adige are a combination of Germanic varieties, which reflect its history as part of the Austro-Hungarian Empire, and 'international' varieties, mostly of French origin. The warmer Adige Valley provides ideal growing conditions for heat-loving vines such as Lagrein and Cabernet Sauvignon, while white grapes and Pinot Nero produce best results at higher altitudes on the mid-mountainsides.
White grape varieties - known for being fresh, minerally and well-structured - account for 60% of the vineyard area in Alto Adige. Pinot Grigio, Gewürztraminer, Chardonnay, and Pinot Bianco dominate, while Sauvignon Blanc enjoys increasing success. The aromatic, spicy Gewürztraminer variety ā that got its name from the village of Tramin ā is indigenous to the region and has a special place in Alto Adige winemaking. Sylvaner, Müller-Thurgau, Kerner, Veltliner and Riesling grow primarily in the cooler sites, and along with Moscato Giallo, are seeing increasing popularity.
Among red varieties in Alto Adige, the native Schiava grape variety dominates, accounting for around 25% of total vineyard area. The velvety Lagrein, another native variety, is also widely planted. For over a century the noble Bordeaux and Burgundy black varieties, Cabernet Sauvignon, Merlot and Pinot Noir have been planted in Alto Adige. Malvasier and Moscato Rosa, while rare, complete the red varietal assortment.
