The seminar's moderator, Italian wine expert Charles Scicolone, noted that people often dismiss Puglia wines as "too jammy, pruney, and lacking in acidity," but most of the wines we tasted today proved that perception wrong. I learned there are three main grapes grown in Puglia: negroamaro, primitivo and uva di troia, also known as nero di troia and often combined with malvasia nera, which is used mainly as a blending grape.
The cool thing about Calabria is that the region’s wine producers almost exclusively use regional varietals – primarily gaglioppo, plus arvino, greco nero, and magliocco canino in lesser quantities. (Other regional grapes I've never heard of include nerello calabrese and lacrima nera.) We learned that the Calabria region produces varieties that have disappeared or never existed in other regions.
