Different varieties of Sercial are also grown in other wine-growing regions of Continental Portugal, more commonly known as Esgana Cão, due to its notable astringency and high level of acidity.
This variety is resistant to mildew and oidium, and characterised by small bunches of grapes in the shape of a pinecone, and compact and very acidic grapes of a greenish yellow colour. This variety can be differentiated from others by its high acidity and astringency. It is essentially cultivated in the North of the Island and in Câmara de Lobos at altitudes up to 600 metres along the southern coast and up to 200 metres in the North. This variety produces dry wines.
