Wine Grapes

Our Wine Grape Knowledge

We work closely with NZ Winegrowers and their subsidiary bodies ‘Sustainable Winegrowing New Zealand’ (SWNZ) and ‘Bragato Research Institute’ (BRI) to drive initiatives that enable our clients to achieve sustainable wine grape production and wine making.

We also recently celebrated receiving the Brand Reputation through Compliance of Global Standards (BRCGS), formerly known as the British Retail Consortium, for our Blenheim store and have worked with suppliers and industry to drive recycling efforts.

Wine Grape Tech-Know Tips For June


  • Pruning sets up vines to perform at their optimum level for next year’s crop and is also the first step in managing the size of next season’s crop. Factors to consider when pruning include (1) how stressed the vines were post-harvest and whether nutrition and water were available, (2) the timing of pruning which could be affected by labour shortages (late pruning delays bud-burst and growth), (3) if timesaving, mechanical options are available, and (4) your winery requirement for next season.

Consider applying:

  • With winter pruning underway, protect wounds adequately to reduce the risk of wood-infecting fungal diseases, such as Eutypa lata and Botryspheria stevensii. Where possible, apply a pruning wound protectant like PruneTec® or Greenseal Ultra promptly or at least before possible rain or heavy dew. A spray-on wound treatment such as Gelseal Ultra is a good time-saving option. If applied correctly, a spray-on option has been shown to be more effective as a wound protectant than a poorly applied pruning protectant. Try to avoid pruning in wet weather which stimulates spore release.
  • Enhance the breakdown of prunings over winter by applying BioStart Digester to the inter-row area. This encourages saprophytic fungi to break down the woody material, thereby recycling valuable nutrients back into the soil.
