The Quinta da Bica is a Portuguese estate, located near Seia, in the Beira region. It is the origin of the reputed Quinta da Bica wines, which were among the founding wines of the Dão wine region, as well as being among the first wines in Portugal to be estate bottled. The estate's manor, commonly known as Casa da Bica, is the seat of the Viscounts of Sardoal, a cadet branch of the Spanish-Portuguese Sacadura Botte family.
