The supply of high health, grafted grapevines is our nursery's core business. Our success is highly dependent on an ongoing regime of activities both in the nursery and at the laboratory which include:

• Ampelography (true-to-type)

  Ampelographic techniques are applied to verfiy that all mother vines of rootstock and budwood are true-to-type. With this rigorous process a high level of confidence can be given to confirm that the provenance of the plants are known and accurate.

• Elisa and PCR Testing

  All our propagation source material is Elisa tested for GLRaV Type 3 each year. Corbans Viticulture has established high health rootstock blocks from selected mother vines. One of the selection criteria is a negative test for 12 viruses by PCR. The monitoring of all source blocks by Elisa and PCR testing is ongoing.

• Physical Specifications

  All our grafted grapevines must comply with a set of physical specifications that are reviewed every year.

• Barcoding

  Barcoding is an essential element in our traceability and quality management systems. It enables us to track and troubleshoot any future issues and provides information on:

  • Budwood, rootstock source, virus-testing and harvesting data
  • Production treatments before grafting
  • All relevant grafting information
  • Nursery and grading data
  • Despatch data
