Arctic char is a freshwater fish native to Alpine lakes and arctic and subarctic coastal waters. Salmerino del Trentino refers to fresh char fish farmed in the pure, cold waters of numerous Trentino lakes and reservoirs, namely within the provinces of Trento and Brescia. The qualitative characteristics of this fish are directly linked to the production area.
In particular, the waters in which Trentino char is farmed originate from perennial snowfields or glaciers; they are extremely abundant, present high levels of oxygen, favorable biochemical qualities and have a fairly low average temperature.
