This vine training belongs to the group of trellis training systems. It was named in California in the early 1980s by the Australian viticulture expert Dr. Richard Smart (*1945) and the Californian vintner John Dyson, on whose vineyard it was first tested. It is a cordon training in which the short cones are directed upwards and downwards. The developing shoots are also formed upwards and downwards (as in Scott-Henry training). The system produces high yields and is suitable for mechanical use in pruning and harvesting. From the 1990s, it was widely used in Argentina, Australia, Chile, Portugal, Spain and the USA. A system based on Smart-Dyson is called Ballerina. See also lists under vine training (Systems) and Vineyard Care (Activities).
The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
