What is "tarrango"

Tarrango is a red grape variety used in Australian wine production. This slow-ripening grape was created in 1965 by the CSIRO Horticultural Research Station at Merbein in Victoria, Australia, as a hybrid of Touriga Nacional and Sultana in order to create wines of good acidity, but low in tannin. Its wines are often similar to Beaujolais in style. Requiring an unusually warm climate, it is principally grown in the wine-producing areas of northern Victoria.
