Increasing practice (also field, open field, green, site greening or stem grafting) of grafting the graft (top part) of another grape variety onto a vine rooted in the vineyard. This has a tradition especially in southern countries. In this way an entire vineyard can be "re-grafted" and, for example, a Riesling can be turned into a Pinot Noir. Although this is somewhat more expensive than planting new vines, the yields are satisfactory after only one year. In addition, the roots already reach deep into the soil due to their age. This is an alternative to classical grafting, where the vine can only be planted in the vineyard after grafting, growing together and care in a nursery.
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
