Minimal Pruned Cordon Trained

This educational system (also MPCT, Minimal Pruning, Non-pruning-system) was developed at the CSIRO research institute in Australia in the 1990s. It is an extensive system with the aim of reducing the amount of work as much as possible. It is also used in trellis training. All maintenance measures in the vineyard are carried out almost exclusively by machine. Manual work is only necessary in exceptional cases. After the vine has been built up and the cones have been cut back to short shoots by machine in the years of harvest only in the direction of the cordon.

The system creates a completely different leaf canopy structure and grape zone; the shoots are located on the outer part of the large leaf wall. Although the high eye-numbers result in a significantly lower shoot rate, the number of shoots is still greater. The growth of the shoots decreases significantly, the grapes are looser and smaller, the berries have a smaller diameter. There is not yet much experience available. Advantages are, apart from the greatly reduced effort in terms of foliage care, lower susceptibility to botrytis and downy mildew as well as rapid leaf surface development. Disadvantages are a greater tendency to water stress and trickle as well as very many small grapes.

After the conversion in the first year with high yields, a balance between shoot development and root mass is established in the following years. The vine regulates itself, so to speak, which corresponds to the natural development of the vine. The grape harvest can only take place with a grape harvester. The system is not suitable for all grape varieties. Very good for Bacchus, Dornfelder, Müller-Thurgau, Kerner, Riesling and Scheurebe. Only conditionally for BlaufränkischThe varieties are: Blauer Portugieser, Grüner Veltliner, Merlot, Pinot Noir, Pinot Meunier, Traminer and Zweigelt. See the complete list under Educational system (Systems) and Vineyard care (Activities).
