The grape has traditionally been one of the most popular grapes planted on the small island of Madeira since vines were first planted there in the 15th century. It was however badly affected by the Phylloxeraplague and the number of vines has decreased greatly in the century since then. Since 1993 any Madeira wine labeled as Verdelho must contain at least 85 percent of the grape, which wasn't previously the case. The variety of Madeira wine known as Verdelho lies between those of Sercial and Bualin style, being drier than Bual but not as dry as Sercial. The variety is known for its high acidity when aged, but if drunk young generally possesses more fruit flavor than the other Madeiras. Some producers are experimenting with making a table-style wine by allowing the grapes to ripen more prior to harvesting and blending with the grape Arnsburger to balance Verdelho's naturally high acidity.
Other regions
Verdelho is one of the three traditional varieties grown on Pico Island in the Azores, which exported it to mainland Europe before the variety was all but wiped out in the phylloxera plague. Returning to their roots, the islands of the Azores have been planting the grape again, which is made into fortified wines like Lajido. The grape is also grown in the Douro valley, where it is sometimes confused with the Gouveio grape. It is also a small component of some Vinho do Dão. Portuguese Verdelho is noted for its higher sugar content compared to what is typically achieved in the warmer climate of Madeira. Verdelho can also be found in Argentina, with at least one producer marketing a varietal called simply Verdelho. In Spain Verdelho is grown under the synonym Verdello.. The grape has been successful in the vineyards of Australia, particularly the South Burnettwine region in Queensland, Hunter Region, Langhorne Creek, Cowra and the Swan Valley. Australian versions of Verdelho are noted for their intense flavors with hints of lime and honeysuckle and the oily texture that the wines can get after some aging. As one of the few heat-loving white grapes, Verdelho is well adapted to the California Sierra foothills. By the 1870s the grape was extensively grown in what is now Amador County. Currently Verdelho is grown in Amador and Solano counties, near Lodi, as well as one vineyard in Napa Valley. Approximately 200 acres in California are devoted to the grape. California Verdelho wines are noted for floral and citrus aromas.
Viticulture
Verdelho is a moderately vigorous vine that produces small bunches of small oval berries with a high skin to juice ratio. The skins of the berry can be thick and taste "hard" when eaten. The grapes ripen early but can be prone to powdery mildew. The vines can also be susceptible to frost during the spring.
Confusion with other grapes
Verdelho is often confused with Verdelho Tinto, a red grape also grown in Madeira. The grapes are related but still different, similar to how Pinot noir and Pinot gris are related. Verdelho is also confused with the similarly named Verdelho Feijão and the Gouveio of Portugal, the Italian grapeVerduzzo and the Verdejo white grape grown in Spain.
