The education system belongs to the group of so-called floor education systems. The winemaker Scott Henry from the US state Oregon (Umbqua Valley) had in his vineyards in the early 1970s with the vigor of his vines big problems. This was expressed by foliage compaction, increased occurrence of fungal diseases, sinking yield and low color intensity in red wines. The winemaker increased the steak thickness from two to four long fruit rods. The evolving ones shoots distributed Henry (as with the Smart-Dyson education ) up and down. Thus, a vertical two-part foliage wall was reached.
The system brings high yields and is suitable for machine use. It represents a good alternative to espalier The main advantage over this is the 60% larger leaf surface and thus higher yields. It is used today in some variants worldwide in many wine regions at such locations where the shoot growth is very strong. In Geisenheim a special variant was developed with only half the tapping strength, ie two fruit tars. See a listing of all systems at training system,
