Polenghi draws its inspiration from the culture of Sicilian lemons, particularly from the Spinagallo estate located in Syracuse. This historic estate cultivates a unique variety of organic lemons, the Femminello Siracusano, celebrated for its exceptional quality. Each lemon is carefully selected and pressed using traditional machinery, preserving a know-how passed down through four generations. The Spinagallo estate also emphasizes environmentally friendly practices, ensuring ethical and organic products since the 1990s.
