Grignolino del Monferrato Casalese DOC

Grignolino has been cultivated in the Monferrato hills for centuries, with the first documented written mention dating to 1249, found in a deed of rent executed by monks from the Chapter of Sant'Evasio in Casale Monferrato. By the early 20th century, the variety commanded prices comparable to Barolo, prized for its pale color and elegant character; a professor of viticulture at the Regia High School of Agriculture in Milan described it as 'a choice wine, light, clear garnet colour.' The wine fell from fashion after the 1970s as sweeter styles and fuller-bodied reds gained global market share. The formal DOC designation established in 1974 aimed to protect the grape's identity, and today Grignolino is experiencing a revival among sommeliers and enthusiasts seeking fresh, indigenous expressions, helped by initiatives such as the Monferace association.

• First written mention of Grignolino dates to 1249 in a deed of rent from the Chapter of Sant'Evasio in Casale Monferrato; a 1337 Abbey inventory lists wines under the name 'Grignolerii'
• In the early 1900s, Grignolino commanded prices comparable to Barolo and Barbaresco; it was considered one of Piedmont's principal grapes
• Popularity declined from the 1970s onward as sweeter wines and richer international styles displaced elegant, lighter reds in global markets
• Contemporary revival driven by indigenous variety enthusiasts, sommeliers, and producers under the Monferace project, launched with the 2015 vintage

The Grignolino del Monferrato Casalese DOC occupies the rolling Monferrato Casalese hills, also known as Basso Monferrato, a system of hillsides ranging from approximately 120 to 350 meters above sea level centered on the commune of Vignale Monferrato. The Alps lie roughly 130 kilometers to the north and the Ligurian coast approximately 90 kilometers to the south, creating a continental climate moderated by both alpine and maritime influences. Soils are predominantly calcareous, argillaceous, and marly, often with sandy and silty fractions, sitting on an ancient seabed; these limestone-clay combinations give Grignolino its mineral backbone while the hilly exposure ensures adequate drainage for the thin-skinned berries. The zone is geographically defined between the Po and Tanaro rivers, a territory recognized as a UNESCO World Heritage Site as part of the Piedmont Vineyard Landscape of Langhe, Roero and Monferrato in 2014.

• Hillside vineyards range from approximately 120 to 350 meters elevation; the Alps and Ligurian coast both exert climatic influence, creating warm summers and cool autumns
• Soils are predominantly limestone, clay, and marl in various combinations, often with natural sandy sediments; vineyards must be exclusively hilly per DOC regulations
• Zone defined between the Po and Tanaro rivers within the Aleramic Monferrato; the wider vineyard landscape was declared a UNESCO World Heritage Site in 2014
• Minimum vine density of 4,000 plants per hectare required; traditional Guyot pruning and low spurred cordon are the mandated training systems

Grignolino is the defining grape of this DOC, a native Piedmontese variety producing characteristically pale, translucent red wines that can appear almost rose-like in the glass. Its most distinctive ampelographic feature is an exceptionally high seed count of four to seven pips per berry, compared to the typical two found in most wine grapes; these abundant seeds contribute significant tannins and bitterness despite the grape's thin skin and light pigmentation. Modern producers use short maceration periods and gentle pressing to manage seed tannins and preserve the wine's pale hue and vibrant acidity. The variety is also prone to millerandage, with uneven ripening within clusters that can affect yield and quality from vintage to vintage. The resulting wines occupy a stylistic space that has been compared to a lighter Nebbiolo: pale ruby tending to orange with age, high acidity, firm tannins, and a characteristic pleasantly bitter finish.

• Grignolino carries 4 to 7 seeds per berry (versus the typical 2 in most varieties), producing firm tannins and notable bitterness despite thin skin and light color
• Minimum 95% Grignolino required since 2021; Freisa and/or Barbera permitted up to a combined maximum of 5%
• The variety is highly prone to millerandage and clonal mutation, creating significant variation in yield and aromatic expression across sites and vintages
• Aromatic profile: red cherry, cranberry, wild strawberry, rose petal, white pepper, and alpine herbal notes; palate shows high acidity, firm tannins, and a bitter almond finish typical of the variety

Accornero, founded by Bartolomeo Accornero in 1897 and now in its sixth generation with Francesca Accornero, farms 25 hectares of calcareous-marl hillside vineyards in Vignale Monferrato. Their 'Bricco del Bosco' bottling comes from a vineyard planted in 1961, farmed organically; a Riserva 'Vigne Vecchie' version from the same site undergoes extended oak aging. Castello di Gabiano, located in Gabiano, is a historic estate of 260 hectares with 20 hectares under vine, whose cellars beneath the castle date to the 12th century and whose archives document winemaking traditions going back to the 13th century; their Grignolino is released under the 'Gavius' label. Tenuta Tenaglia in Serralunga di Crea farms vineyards at the upper end of the DOC's elevation range and is a member of the Monferace association for its oak-aged expression. The Consorzio di tutela vini Colline del Monferrato Casalese oversees the DOC alongside related appellations Barbera del Monferrato Superiore DOCG, Rubino di Cantavenna DOC, and Gabiano DOC.

The Grignolino del Monferrato Casalese DOC was established by DPR on June 26, 1974, and is overseen by the Consorzio di tutela vini Colline del Monferrato Casalese. A 2021 revision raised the minimum Grignolino content from 90% to 95%, restricted permitted co-varieties to Freisa and/or Barbera at a combined maximum of 5%, set a minimum natural alcohol of 11.5% for standard wines, and introduced the 'vigna' single-vineyard mention. The Riserva designation requires a minimum of 12% ABV and 30 months total aging from November 1 of the harvest year, with at least 18 months in wooden barrels; cork closure is mandatory for Riserva. A Spumante Rosato Metodo Classico typology was approved in August 2024 and became claimable from the 2024 harvest, requiring a minimum of 18 months on lees. Regulations prohibit the use of qualifications such as 'superiore,' 'fine,' 'scelto,' or 'selezionato' on any label.

Casale Monferrato, the historic center of this DOC, sits on the Po River and offers enotecas, wine bars, and direct producer visits across the surrounding hillside landscape. The broader Monferrato area is recognized as part of the UNESCO Piedmont Vineyard Landscape of Langhe, Roero and Monferrato, inscribed in 2014; a distinctive feature of the area is the infernot, underground rooms carved by hand from tuff rock, traditionally used for wine storage. Harvest runs from late September through early October for Grignolino, making the autumn months ideal for visits. Local cuisine is deeply intertwined with the wine: vitello tonnato, agnolotti del plin, fritto misto Piemontese, bagna cauda, and salumi from the Monferrato tradition all complement the wine's bright acidity and characteristic bitterish finish.
