Terroir

• The zone is entirely mountainous according to ISTAT, with flat surfaces limited to the valley floor and vineyard sites extending up to 800 metres above sea level.
• The soils of the foothill slopes consist predominantly of high-stoniness calcareous debris, which ensures good drainage and aeration conditions.
• On the lower parts of the slopes and in the basins, soils with lower stoniness are found, while in some flat areas colluvial accumulation soils are present, overlying moraine deposits or fluvial gravels.
• Soils also occur on geological matrices other than limestone, such as the porphyritic matrix of the Valle di Cembra, the basaltic belt of Isera, Mori and Brentonico in the central Vallagarina, and the schistose-micaceous matrix of the Valsugana.
• A valley breeze called the 'Òra', coming from Lake Garda, blows every day of the year from midday to sunset, moderating the climate of part of the Trentino territory.
• The climate in the growing zones features relatively cold, snowy winters and warm summers, often sultry during the day, while in the Alto Garda and lower Valle del Sarca area the climate is milder and sub-Mediterranean in character, owing to the moderating influence of Lake Garda, Italy's largest lake basin at 370 km².

• The Trento appellation was recognised on 9 July 1993 as the first Italian appellation reserved exclusively for sparkling wine produced by the method of bottle refermentation.
• The grape base comprises Chardonnay, Pinot bianco, Pinot nero and Meunier, varieties identified locally as the most suitable for sparkling-wine production by the method of bottle refermentation.
• The traditional training systems of the zone are the single pergola, the double pergola, and vertical trellis forms such as Guyot and cordon spur.
• The sparkling-wine production process requires a minimum period of lees ageing of 15 months, raised to 36 months for the Riserva wine type.
• Grape seeds found at the pile-dwelling settlement of Ledro testify that viticulture in this area dates back to the Early Bronze Age, between 1800 and 1600 BC.

• The sparkling wines display balanced chemical and physical parameters, particularly with regard to the acidity/alcohol ratio, with organoleptic characteristics traceable to the grape varieties of origin.

• The pronounced diurnal temperature range during the final stage of grape ripening imparts to the wines the aromatic finesse that characterises them.
