Madeira is a wonderful wine that is often misunderstood, certainly it is little known here in Spain. Whenever I am in Portugal, I try and stock up as it is very difficult to get much here. Recently, I was fortunate enough to taste a series of Madeiras from Henriques & Henriques, one of the top Madeira producers. We tried 3 wines, all 10 yr old single varietal Madeira. The four noble varieties of Madeira are (from sweetest to driest): Malmsey, Bual, Verdelho, Sercial. Wine from the noble varieties must be aged at least 5 years and will indicate the age and grape variety on the label. As with all EU wines, 85% of the contents must be from the designated grape variety in order to put it on the label.
