ONAS was established in 1999 when the association was registered in the Chamber of Commerce, Industry, Agriculture and Artisanship of Cuneo (Piemonte region), receiving legal recognition in 2009.

It is a non-profit association that provides its members with specific skills in sensory analysis. Using his/her human senses, a trained ONAS taster is able to objectively evaluate a cured meat product, thus promoting its knowledge, culture and territory to which it belongs.

ONAS is structured in territorial delegations that organise periodical tasting sessions reserved for its members.
