Exploring Terroir: A Deep Dive into Tedeschi’s Scientific Study at a Leading Veneto Wine Producer

By | 19 March 2025

The Tedeschi family winery, a prominent producer in the Veneto region, has seen a significant evolution in its winemaking style, particularly under the guidance of Lorenzo Tedeschi since the 1960s. Lorenzo focused on enhancing quality production by recognizing the unique potential of grapes from the Monte Olmi vineyard, leading to the introduction of single-vineyard Amarones—a pioneering move in the area.

Now managing 46 hectares of mostly elevated vineyards, the family continues to maintain the traditional and historical essence of their wine production. In 2005, they expanded their holdings by acquiring the Maternigo estate, chosen for its exceptional soil characteristics. This estate, located between Tregnago and Mezzane di Sotto, comprises 34 hectares of vineyard planted in 2008, with calcareous soil intermingled with loam and clay.

To foster a deeper understanding of their terroir, the Tedeschis initiated a comprehensive research project collaborating with the University of Verona. This research involves studying the various soil types within their vineyards, aiming to discover how these affect the characteristics of both the grapes and the wine. Led by Professor Maurizio Ugliano, the team has focused on five vineyards over three vintages, hoping to identify any consistent aroma profiles attributed to specific locations, despite the variable nature of vintages. The findings have illuminated not just the influence of grape-derived compounds, but also the significant role of yeasts, which produce distinct aroma signatures linked to nitrogen levels in the must.

Their typical approach to Amarone distinguishes their style further; they prefer drier wines over the more common soft, residual sweetness currently trending. The drying process of grapes is meticulously controlled to maintain quality, avoiding botrytis while ensuring optimal humidity levels. After this drying phase, grapes undergo a cold maceration, followed by fermentation, and are then transferred into large barrels for aging, which helps to retain the true character of their terroir.

During a visit to the Tedeschi vineyards, two notable sites—La Fabriseria and Maternigo—were explored, showcasing revered limestone soils. The family also maintains a robust archive of vintages, which now totals around 20,000 bottles, allowing for historical perspective and insights into their evolving winemaking practices.

Their recent wines reflect this dedication, with distinct profiles across various vintages—each showcasing the complexities of their vineyards and the artisan touch of the Tedeschi family. Their commitment to quality and tradition continues to stand out in the landscape of Italian winemaking.
