Designation (also direct, self-carrier, French producteur direct) for "root-genuine" Rebsorten, with which no finishing
took place - they are, so to speak, "on their own foot". The term is only in connection with the introduced in the second half of the 19th century, the current practice of grafting of precious rice on American documents
(Rhizomes) emerged. This has been successful phylloxera
fought. Before the occurrence of the pest in Europe, this measure was not required and thus all the vines were direct carriers. Certain American vines
are often cultivated as direct carriers (especially in the USA), as some of them are more or less resistant to re-flowering and thus no grafting is necessary.
American vines are not as often claimed a priori direct carrier, because these are usually refined (and are thus no longer direct carriers). A well-known "direct carrier wine" from American grape varieties is the Austrian specialty Uhudler
, Contrary to some sources, there are no restrictions within the EU on direct carrier wines. An often asked question is how well the wines tasted "before phylloxera". But that is, in spite of not so few producers ungrafted
Rebstock, not so easy and unfortunately hard to understand. See under Pre-Phylloxera
