Cortese is a white grape variety originating from the Piedmont region in Italy and is most widely known as the main variety used in producing the dry white wines of Gavi. It is also grown in other regions of Piedmont and in the Lombardy region.

Cortese has a light greenish yellow hue. Its aroma is characterised by floral and fruity notes of white flowers, peach and citrus. The taste profile is dry and crisp with a medium body and a good acidity.

Cortese is mainly grown in the Piedmont region of Italy, where it is used to produce the famous Gavi appellation. It is also grown in the Lombardy region and other parts of Piedmont. Cortese is a relatively low-yielding and early ripening variety that is relatively resistant to disease. It prefers warm, sunny and dry climates and performs best on soils that are well-drained and composed of clay and limestone. The winemaking process involves long and slow fermentations at low temperatures. Gavi is the most famous wine made from Cortese and is a dry, crisp and light-bodied white wine. It has aromas of white flowers, peach and citrus, and a good acidity. Other Piedmont wines made from Cortese include Colli Tortonesi and Monferrato. Cortese wines are best paired with light dishes such as seafood, salads and white meats.

Cortese is also known as "Star of Gavi" in south-eastern Piemonte, north-west Italy.
