Tinta Negra Mole is a dark-skinned grape variety that is best known as the dominant grape of Madeira. The grape accounts for roughly 70% of vine plants on the island. The grape rose to prominence in the wake of the phylloxera epidemic of the 1860s, as it was disease resistant and had high yields. It is used in Madeira wines and is required by law to contain at least 85% of the grape variety stated on the bottle. Tinta Negra Mole is often confused with Negramoll, but recent DNA profiling has proved that they are separate varieties.
