Why go
Taste across the dry-to-sweet range instead of treating Madeira as one dessert wine. Sercial and Verdelho sit toward the drier end; Boal and Malvasia are sweeter. The contrast makes the wine's ageing method easier to understand than a single glass does.
The full story
Madeira wine grew alongside Atlantic shipping. Vessels stopping at the island carried wine on long voyages, and producers noticed that heat and movement changed its character. Wine that made a round trip became known as vinho da roda. Sending casks to sea was costly, so producers developed ways to create a similar effect on land. Heating and controlled exposure to oxygen became part of the wine's identity, helping give Madeira its characteristic depth and durability. Fortification means adding spirit to the wine; it is part of the process, but it does not make every Madeira equally sweet. Sercial is generally dry, Verdelho sits further toward medium dry, Boal is sweeter, and Malvasia, also called Malmsey, is the richest of the familiar styles. At a tasting, moving from a drier glass to a sweeter one makes those differences clearer. The range also explains why a dry Madeira can be served before a meal while a sweet one can accompany dessert.
