Trebbiano is an Italian variety of white vine (Vitis vinifera). It provides good harvests, but the wine that is made with it is little distinguished. It can be fresh and fruity, but it is not preserved for a long time. Its high acidity makes it important in the production of cognac. It is also called ugni blanc and has many other names (saint émilion, white hermitage, white shiraz) reflecting a family of local subtypes, particularly in Italy and France.
