The red grape variety is a new cross between Teroldego x Merzling. The cross was made in 1994 at the Istituto Agrario di San Michele all'Adige(Trentino). The medium to late-maturing vine is highly resistant to both types of mildew, which is why it is considered a PIWI variety. No stocks were reported in 2016 (Kym Anderson).

If I were to rate websites, you would deserve the highest rating. It is rare to come across websites that provide such a large amount of data and are still so intuitive to use. Respect for the lovingly researched and informatively prepared encyclopedia. Keep it up!
