Boal, often Anglicized to Bual, is the madeira name for the malvasia Fina grape. Most of the Boal growing to a limited extent on Madeira today—though not nearly as limited as the island’s other three ‘noble’ varieties—is Boal Cachudo. Portugal’s Instituto da Vinha e do Vinho (IVV) lists four other subvarieties of Boal: Boal Barreiro, Boal Branco, Boal Espinho, and Boal Ratinho.
