WSET D3 - North East Italy Flashcards
Summarise Trentino-Alto Adige.
Influenced by Austrian heritage, became part of Italy in 1919. Trentino predominantly Italian-speaking region, while Alto-Adige (AKA Südtirol) majority first language is German. Entire region in foothills of Alps, viticulture predominantly practiced on lower slopes of hills. Both international and local varieties. Most single-variety wines.
Summarise Trentino.
Mainly whites (unoaked, fresh PG, Chardonnay and Müller-Thurgau) reds from Teroldego, Merlot and Marzemino. Good to very good, inexpensive to mid-priced. Few very good to outstanding, premium to super-premium. Over 80% by co-operatives.
What is the growing environment and Grape growing like in Trentino?
In sight of Alps, moderate, continental but cooling influences. Daytime summer temperature high due to mountains providing protection from cold north winds, moderating presence of Lake Garda to south and heat building up on valley floor during growing season.
Large day/night temperature differences due to cold air descending from mountains at night - retain acidity, prolong growing season, flavours to intensify. Vineyards on higher and steeper slopes require working by hand (harvesting).
Summarise the grape varieties used here?
75% white grapes and 25% black. Maximum yields high. Large number varieties. Overarching Trentino DOC allows 10 white varieties to be bottled as single variety and 9 black varieties as reds. International varieties widely grown: Pinot Grigio, Chardonnay, Müller- Thurgau, Pinot Bianco, Riesling, Sauvignon Blanc and Gewurztraminer in whites and Merlot, CS, CF and PN in red. Larger volumes Pinot Grigio and Chardonnay.
Also home to range of local varieties. Black varieties Teroldego (black cherry), Marzemino (red cherry) and Lagrein (red cherry and black plum), all closely related. All vigorous, mid to late-ripening - deeply coloured, M tannin wines. Good to very good, inexpensive to mid-priced.
What are the top varieties planted?
Pinot Grigio
Chardonnay
Müller Thurgau
Teroldego
Merlot
Marzemino
Describe Teroldego.
Historically on pergolas for high yields. Quality minded growers using Guyot. Can suffer from drying out of stems but less susceptible to mildews. Best quality from Teroldego Rotaliano DOC on sandy and gravelly soils in far north Trentino. Outside Teroldego Rotaliano DOC, Teroldego cannot be bottled as Trentino DOC but as Vini delle Dolomiti IGT (includes wines from both Trentino and Alto-Adige).
Describe Marzemino.
Prone to botrytis and powdery mildew. Older vines trained on pergolas; newer lower-yielding clones trained as spurred cordons. Best, ripest wines from Ziresi subzone of Trentino DOC due to full sun exposure and rich calcareous/clay and basalt soils.
Describe Lagrein.
Needs warm site with plenty sunshine to ripen fully. Can subject to poor fruit set thus low yields. Bitterness and some harshness on finish addressed by shorter maceration and oak ageing. Because its deep colour, also used for rosés. labelled Italian or German as ‘red’ and ‘rosé’: Lagrein rubino/dunkel and Lagrein rosato/kretzer.
Describe Moscato Rosa.
Made into rose-scented sweet wines. Poor fruit set and susceptibility to botrytis make it difficult to grow. Appassimento method or late harvest. Premium priced.
Describe Nosiola.
Grown in Valley of Lakes, warmest area with sub-continental climate. Produces small volume distinctive whites with light hazelnut flavour. Also made in semi-dried fruit version, called Vino Santo. Hazelnut flavour from fruit, not oak. Vulnerable to spring frosts, powdery mildew and sour rot. Dry wine mid-priced, Vino Santo premium priced.
What’s winemaking like in Trentino?
Majority whites by soft pressing, stainless steel at low temperatures (12–16°C) to retain primary fruit. May briefly aged on lees released promptly for fruitiness. Some top whites may aged in small oak, small proportion new, added layer of vanilla and spice.
Reds: 2 styles, Most fresh and fruity.
M tannins and M body. By maceration on skins during alcoholic fermentation (5–7 days) moderate temperatures (17– 20°C). Briefly aged in stainless steel or old, neutral wooden. By contrast, minority premium reds go through period maceration after fermentation (additional 7–14 days) and warm temperatures (26–32°C). Typically aged in small oak with small proportion new oak. M (+) to intense fruit and additional layer of vanilla and sweet spice oak.
Wine law and Regulations.
Trentino DOC allows many varieties, international and local:
* Bianco (min. 80% Chardonnay and/or Pinot Bianco)
* Rosso (single variety or blends of CS, CF, Carmenère and Merlot)
* single variety, min. 85% named variety
* two variety blends. eg, for whites, 50–75% one of Chardonnay, Pinot Bianco, Pinot Grigio or SB + remainder one of these.
* Rosé / Rosato or Kretzer.
There are DOCs for sweet wines. Certain important sub-zones can appear on labels with DOC Trentino, e.g. Val di Cembra.
For Pinot Grigio delle Venezie DOC available to growers in Trentino but not Alto Adige.
Wine business.
Many small growers. Co-operatives and merchants very significant. Co-operatives 80% total production with largest, Cavit, 60% all wine. Smaller estates 10% total production. Trentino DOC allows most common varieties, with alternative option of Vigneti delle Dolomiti IGT. Very high proportion bottled as DOC, questionable if Trentino DOC as such has promoted uniformly high quality as its yield allowances are high. Encouraged some high- quality growers not use Trentino DOC.
Very good penetration in restaurant sector, especially Trentodoc, Müller Thurgau and Teroldego Rotaliano.
Summarise Alto-Adige.
Viticulture practiced in valleys and lower slopes of Dolomites. Today produces pale red Schiava then mostly international varieties PG, Gewürztraminer (here regarded as a local variety; village of Tramin is in province), Chardonnay, PB, PN and SB. Mostly good to very good, inexpensive to mid-priced. Some top wines very good to outstanding, mid to premium priced, especially PN. 60% white, 40% red.
What’s the growing environment and grape growing like in Alto-Adige?
Mild Alpine continental climate. Protected from cold winds by mountains to north.
300 –700 m. Warm air currents in valleys, 300 days sunshine and large day/night differentials - very good conditions for ripening grapes and retaining acidity. Sufficient rainfall, throughout year with low amount in winter. Rainfall sometimes a concern at harvest time. Large variety soils: volcanic porphyry, quartz and mica rock and Dolomitic limestone, suitable for range varieties. Either traditional pergola or Guyot. Leaf picking encourage exposed bunches to ripen but now, with rising temperatures, has to be done carefully avoid fruit burning or drying out. Vineyards on higher, steeper slopes require working by hand. Number of growing zones (not sub-zones within DOC) according to topography, climate and soils. 2 largest are:
* Bassa Atesina in south with warmer climate: all main varieties are grown except Schiava. Müller Thurgau is grown at high altitude.
* Oltradige, including Lake Caldaro area for Schiava, with Merlot and CS in valleys, PN and white varieties at higher altitudes.
What are the top varieties?
Schiava
Pinot Grigio
Gewurztraminer
Pinot Blanc
Chardonnay
Lagrein
Pinot Noir
Sauvignon Blanc
Describe Schiava.
4 separate varieties identified, normally grown, vinified together. Typically on pergola to cope natural vigour, high yields. Typically pale ruby with perfumed violet and strawberry with M to light body and low tannins. In Santa Magdalena DOC Schiava can be blended with up to 15% Lagrein producing deeper coloured, fuller bodied wine.
What is winemaking like in Alto-Adige?
Most white aim to preserve fresh fruit. Fermented at low to moderate temperatures (12–15°C) with selected yeasts and aged in stainless steel. Mid-priced may kept on fine lees 4–6 months to fill out body, premium wines for nearly a year. Some top whites and reds (Lagrein, Pinot Noir) aged in barriques.
Wine Law and Regulations.
98% are DOC. Alto Adige DOC used for typical range varieties. wines can be:
* Bianco (min 75% Chardonnay, Pinot Bianco or Pinot Grigio – 2 of these must present but no single variety can exceed 70%). No Rosso category.
* single variety, min 85% named variety.
* two variety blends, eg, Chardonnay-Pinot Bianco or Cabernet-Lagrein. both varieties must be more than 15% blend each.
Also possible to label wine in this DOC with 1 of 6 subzones. Largest is Alto Adige Valle Isarco (mostly whites). Separate Lago di Caldaro DOC is devoted to Schiava.
Allowed yields slightly lower than Trentino, eg. 90 hL/ha for whites.
