Sercial is the name of a white grape grown in Portugal, especially on the island of Madeira.

It has given its name to the driest of the four classic varieties of Madeira fortified wine.

[1] The grape is grown in diminishing quantities at the southern end of the island.

[3] The anglicised name Sercial came to be associated with the Madeira style rather than the grape variety, being the lightest, most acidic and delicate expression of Madeira that takes the longest to mature.

For obscure reasons, Sercial was the name given to the Gascony grape Ondenc when it was planted in Australia.
