The history of grignolino: roots and legacy of a great Piedmontese grape Dive into the enigmatic world of grignolino with this compelling historical investigation by renowned researcher Pietro Stara. Using an "evidential paradigm"—a detective-like approach—Stara uncovers the mysteries and complex identities of a grape variety that has shaped Piedmontese viticulture, yet whose history has often been overlooked. A historical enigma unfolds The journey begins in the 13th century (1249), tracing the grape’s earliest footsteps back to the monks of Sant’Evasio in Casale Monferrato. At the time, it was known as "Berbesino" or "Barbesino". It wasn’t until a 1614 inventory of the Casale Castle that the name "grignolino" finally appeared in official records. Key highlights of the research: The identity quest: discover how 19th-century ampelographers like Demaria, Leardi, and the traveler Giorgio Gallesio solved the puzzle of its many synonyms, confirming that the "barbesino" of Alessandria and the "grignolino" of Asti were, in fact, the same soul. The etymological debate: the book tackles the fierce disputes linking grignolino to barbera, debunking myths through the rigorous historical analysis of scholars like Senator Desana and Dalmasso. A sparkling past: in a surprising revelation, the text explores grignolino’s role as a pioneer of Italian sparkling wine. Long before its current still-wine reputation, it was crafted using the Méthode Champenoise, winning prestigious awards and ranking as a top choice for spumante production as late as 1924. The white mystery: the investigation even touches upon the elusive "white grignolino," a rare variety mentioned in historical texts and immortalized in the famous 1858 wax fruit models by Francesco Garnier Valletti.

History, mathematics and abduction ¹, or hypothesis, is one of the main modes of inference used by the human mind, alongside deduction and induction. It is a logical process that allows one to draw a conclusion starting from two premises. In practice, abduction is the reasoning that allows us to infer a cause or explanation starting from an observed result and a general rule. Abduction The process develops in this way: a surprising phenomenon (C) is observed and it is hypothesized that, if a certain condition (A) were true, then that phenomenon (C) would be its natural consequence, meaning that the observed phenomenon can be explained as a normal result of that condition. An example provided by the famous mathematician Charles Peirce helps clarify this concept better. Suppose a person enters a room and finds several bags filled with beans of various types. On the table there is a handful of white beans. After careful observation, the person discovers that one of the bags contains only white beans. From this observation, they infer that the handful of white beans probably comes from that bag, since that bag contains only white beans. ¹ Cf. Umberto Eco and Thomas A.
