The second masterclass entitled “Gen D: Derthona’s Next Gen gets con the ” was an anti-conventional proposal led by Derthona Giovani, an association active con the Tortona ambiente that aims to promote local food and wine culture among young people, aged 15-41, and enthusiasts.
Danilo Altura, an expert con the sector, acted as moderator con the discussion of the masterclass “how to attract young consumers?” very interesting topic for professionals.
Derthona, the white that defies time
Decanto had the pleasure of participating con the first of the Derthona .Nullità Masterclasses held by the legendary Walter Ammasso, born con 1965, oenologist-viticulturist who promoted the rebirth of Timorasso. Born and lived con Monleale, con the Tortonesi Hills, where he works con the family business, he is a controversial character, genius and recklessness, well known nationally and beyond!


Timorasso, the grape variety
The Masterclass opened with Davide Ferrarese’s presentation of the Timorasso grape.
It is naturally a native Piedmontese white grape variety, originating from the south-eastern ambiente which, Davide underlines, is unique con the essence of the variety con the Tortona hills because it has risposta negativa clones.
It comes with bunches of different sizes, more less compact, with round berries, with thick golden yellow skin.
Timorasso is a difficult vine to grow because it is sensitive to rot and botrytis. Per fact, the most suitable soils for growing vines are the highest, well-ventilated and drained hills. Furthermore, it requires low yields to express itself at its best, putting the energies of the winemakers to the esame.
It is an ancient vine, once widespread con a large ambiente between Voghera, Novese and Genoa. After the advent of phylloxera, this ampelographic specialty had almost disappeared, replaced by more productive and profitable varieties.
It can be safely said that Timorasso was saved by the great recovery work carried out by the far-sighted Walter Ammasso con the 1980s. This happened despite the contrary opinion of some members of the family and the skepticism of many of the other winemakers con the ambiente.
Timorasso, the territory
The Vigneto Veritas agrotechnician continues by placing the Timorasso, then describing the Tortonesi Hills.
The beautiful scenario of the rolling Tortonesi hills welcomes us as we leave the city of Tortona: the landscape is authentic, dotted with historic villages and vineyards, interspersed with meadows, woods, cereals, cultivations of quality fruit, cherries, peaches and strawberries, for which it excels con biodiversity.
It is located about an hour from Milan, Genoa to Turin, where the hills are located at a natural conferenza point between the Po Valley and the Apennine valleys, acceso the south-eastern spur of Piedmont.
Once called Old Piedmont, this border ambiente between Piedmont, Liguria, Lombardy and Emilia is climatically affected by the Po Valley and Ligurian-Emilian Apennine influence, with winters that are acceso average mild and hot summers.
The annual rainfall is 700-800mm, rainfall that Davide Ferrarese considers sufficient for the vine at our latitude.
As regards the soils, the Tortonesi Hills are a mosaic of marine origin where the Sant’Agata Fossil Marl stands out above all. They are deposits rich con limestone that give the wines minerality, structure and longevity.
The presence of marly and sandy soils contributes to the complexity of the Colli Tortonesi territory, which provides Timorasso with a wide range of expressions and charm. Per particular, the ambiente further south of the hills approaches the Ligurian-Piedmontese oceanic domain, richer con clay and limestone, the ambiente further north is poorer, less calcareous, peculiarities are the rocky sediments.
Timorasso, the Colli Tortonesi DOC
The Colli Tortonesi DOC was founded con 1973, only for Barbera and Largo grapes.
Today the DOC covers 1250 hectares divided into 46 municipalities and Timorasso is one of the many native varieties protected by the Consorzio Custodia Vini Colli Tortonesi, the reference con the ambiente which has 115 members.
Consider that con 2000 there were only 3 hectares cultivated con Timorasso, that is, those recovered by Walter Ammasso. But despite this, con 2005 Timorasso was introduced into the DOC and only 3 years later, con 2008, there were 41 hectares of Timorasso sui Colli! This demonstrates a rapid evolution that has led Timorasso to be considered the engine that has given new energy to winemakers to maintain viticulture con the ambiente.
Since July 2015, the Consortium, with the aim of inextricably linking the Timorasso vine to its territory, has decided that the wine produced with this vine can be called Derthona, the ancient name of the city of Tortona.
The tasting, first series of Derthona
First battery: the masterclass opens with the blind service of 6 glasses of wine from the 2024 vintage.


The not very cold winter, the many hot days and the high rainfall made the year difficult. Preserving the health of the grapes with specific treatments has been challenging for winemakers.
What emerges from the six tastings is the coherence of Derthona, despite the difference con style of the cellars. The “newly born” 2024 vintage is characterized by a lively straw yellow color, intense aromas of ripe fruit, such as peach, acacia flowers, wild herbs. Acceso the palate, the typical vibrant but thoughtful acidity and the strong and persistent flavor and the final bitterness invite you to bevanda.
The tasting of Derthona’s second battery
Second batterysame method: the sommeliers serve 6 blind glasses of Derthona 2021.
2021 was climatically significantly different from the 24th: colder, snowy winter, hot summer, but not excessively, average rain.
The 2021 vintage transforms acceso the sense of smell, the Norisoprenoids are distinctly perceived, the evolution of Timorasso excites the entire public with its agenda of hydrocarbons, citrus fruits, flowers and honey, accompanied by light oxidative agenda which increase its olfactory complexity.
Obviously there is diversity con the company style, but even con this tasting the Timorasso expresses coherence: the color is intense straw yellow, full and deep, they are full-bodied, chewable wines, they are tasty, vertical wines.


Despite time, we notice how Timorasso retains its flavor and freshness, which, together with its important structure, highlights how Timorasso’s genetic heritage allows for longevity.
At the end of both sessions the service sommeliers show the bottles and we can finally discover the cellars of the wines being tasted and the valley to which they belong.
