Monitoring and testing of wine
Find out about laboratory testing requirements for wine for export, and water used in winemaking.
Meeting Wine Act requirements
If you make wine using your own water supply or if you export wine, you need to meet certain requirements under the Wine Act 2003. Laboratory testing is used to check that these requirements have been met.
Testing for clean water
If you make wine using your own water supply, you must get your water tested to make sure it is 'clean':
- every year
- when you use a new source of water
- within a month of an environmental event that could affect your water (like a major weather or seismic event).
Samples must be taken from the point of use and tested by an approved laboratory.
Tests for E. coli must be performed at one of the following laboratories:
- any laboratory accredited to ISO 17025
- a laboratory recognised by the Ministry of Health for testing drinking water
- a laboratory approved under the animal products Recognised Laboratory Programme (RLP)
- recognised dairy agencies [PDF, 430 KB]
You must also test your water annually for turbidity – this does not have to be done by an approved laboratory.
Testing wine for export
If you export wine, some countries require a laboratory report confirming that the wine composition meets their requirements. If this analysis is needed to support an official assurance (export certificate) for that country, testing must be performed by a recognised laboratory.
