Diogene 2021 Valli Unite

Diogene Colli Tortonesi Dolcetto 2021

Overview

The Diogene Colli Tortonesi Dolcetto 2021 by Valli Unite is a lively and genuine red wine from Costa Vescovato, Piedmont. Made from 100% Dolcetto, it ferments spontaneously in stainless steel and matures in cement vats. The sulphur addition is minimal (below 40 mg/l), preserving its purity and vibrancy. A straightforward, juicy, and soulful expression of Dolcetto, crafted with respect for both nature and tradition.

Wine History

Diogene takes its name from the philosopher who sought truth in simplicity — a fitting symbol for Valli Unite’s vision of honest, authentic winemaking. Created as a natural counterpart to the cooperative’s Barbera (Gaitu), this wine offers a softer, fruit-driven profile while maintaining the same artisanal integrity. The 2021 vintage brought healthy, balanced grapes that shine through in a wine both rustic and elegant, brimming with freshness and authenticity.

Philosophy in the Vineyard

The Dolcetto grapes come from certified organic vineyards planted on clay-limestone soils between 250 and 300 meters above sea level. The vines are cultivated with green manure, organic compost, and zero chemical inputs, following a philosophy of biodiversity and self-sufficiency. This sustainable approach results in grapes full of life, capable of expressing the true essence of the Colli Tortonesi terroir.

Winemaking Approach

Fermentation is spontaneous with native yeasts in stainless steel, followed by several months of aging in cement vats. There is no fining, no filtration, and only minimal sulphur (under 40 mg/l) added before bottling. The outcome is a pure, vibrant Dolcetto, marked by clarity, freshness, and drinkability — a wine that perfectly captures the honest spirit of natural Piedmont reds.

Valli Unite

History and Origins of Valli Unite

Founded in 1981 in Costa Vescovato, a small village in the province of Alessandria, Valli Unite was born from the vision of three young farmers who decided to join forces and create an independent and cooperative farming community. Over time, that small group has grown into nearly forty members, all sharing a common ideal that goes beyond winemaking — a true cultural and human alliance. Surrounded by the rolling hills of the Tortona area, the cooperative has built its identity on agricultural independence, respect for nature, and collective work, establishing itself as a reference point for sustainable viticulture in Piedmont.

Philosophy in the Vineyard

On its 100 hectares of land, of which 22 are dedicated to vines, Valli Unite cultivates Barbera, Timorasso, Croatina and other local varieties following a strictly organic approach. The estate includes a farm with livestock, which provides natural fertilizer for the fields, ensuring the fertility and vitality of the soil. Green manures composed of leguminous herbs enrich the land and promote biodiversity. Each vineyard is tended by hand, with minimal intervention, allowing the vines to express their true character and the landscape to retain its natural balance.

Winemaking Approach

The cellar of Valli Unite is a place where wine is guided, not manipulated. Fermentations occur without selected yeasts, letting indigenous microorganisms reveal the identity of the grapes and the land. Sulphur dioxide is added only in very low quantities (less than 40 mg/l) to preserve the wine’s vitality and purity. The goal is to produce a living, evolving wine, one that changes over time and reflects the rhythm of nature. Every technical choice is guided by patience, intuition, and deep respect for the raw material.

A Community and Cultural Project

Today, Valli Unite is much more than an agricultural cooperative — it is a self-sufficient rural community that combines viticulture, animal farming, food production, and hospitality. The estate is home to vineyards, gardens, and animals, all managed by people who share the same values of sustainability, solidarity, and simplicity. Wine is just one expression of a broader way of life — a philosophy that connects land and culture, embodying the authenticity of Piedmont’s countryside.
