Manisa, a city in Turkey famous for its viticulture, has found a new source of income by exporting vine leaves, a key ingredient in Turkish cuisine. About 500 tons of vine leaves are exported annually to Mediterranean and Middle Eastern countries, generating around $1 million in revenue. The exported vine leaves, preserved in brine, are priced higher than the local market rate. The Manisa Viticulture Research Institute is also working on registering geographical indications for vines and sultani seedless grapes.
