A system developed in the early 1960s by US viticulture expert Dr Nelson Shaulis (1913-2000) at Cornell University (Geneva, New York) vine training (double-curtain training). It belongs to the group of cordon training systems and is a variant of the reverse training system. The fruit shoots are trained from top to bottom instead of from bottom to top. The system was originally created specifically for the historic Concord grape variety to enable mechanical harvesting. The vines are trained on a high T-shaped (also V-shaped) trellis. The distance between the rows of vines is about three metres. The young shoots are divided to the left and right and the foliage is guided onto two wire frames that can be folded down.

In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".
