The symbiotic Senatore Cappelli penne are made exclusively with durum wheat grown by Terre Alte Picene using the eco-sustainable symbiotic farming technique. Senatore Cappelli durum wheat A variety of ancient wheat developed by the geneticist and agronomist Nazareno Strampelli in the early 20th century. Characterized by an intense aroma and low gluten content, this wheat was a primary food source until the early 1970s, when it was replaced by more productive but less nutritious wheats due to its low yield. For the many beneficial properties and high digestibility of Senatore Cappelli, Terre Alte Picene has never ceased its cultivation.
