Reading the bitterness
The EU geographical-indication (PGI) specification defines Radicchio Rosso di Treviso as red chicory of Cichorium intybus L. var. silvestre, a variety of the chicory genus, with 2 types, precoce and tardivo. This is a legal product category for the geographical indication, not a current reconciliation of botanical taxonomic synonyms.
The same specification recognizes 2 types, precoce and tardivo, but does not state the bitterness intensity specific to precoce. The legal document goes only as far as distinguishing the 2 types; it does not support sensory differences between them with trained-panel numerical data.
According to an introduction on the regional-promotion organization's official Strada del Radicchio site, the first official exhibition was held on December 20, 1900, organized by the Lombard agronomist Giuseppe Benzi (「ジュゼッペ・ベンツィ」). This is based on a tourism and regional-promotion account; original records of the exhibition were not traced in this review.
