Supplying the wine industry
Wine ingredient (commodity) safety requirements
Commodity suppliers supply commodities such as grapes, fruit, vegetables, other plant material or honey which are used for making wine.
Commodity suppliers do not require a Wine Standards Management Plan (WSMP). However, because winemakers trace all the ingredients in their wine, if you supply commodities to a winemaker, you need to keep and provide information about the commodities. Your commodities also must:
- be free from food safety hazards
- not exceed maximum residue levels (MRLs) for pesticides.
You can find maximum residue levels (MRLs) for pesticides in MPI's MRL database. This covers limits for a variety of markets including New Zealand.
Grapes for making wine: safety requirements
If you supply grapes for wine, you must ensure those grapes, when they become wine, are free from hazards that could cause injury to human health.
You must also maintain information about your grapes and provide it to the winemaker, including:
- the source of grapes, such as the grower details and the location of your vineyard
- a description of grapes including quantity, variety, vintage, and area where the grapes were grown – this is particularly important if the information must be on the wine label
- risk factors, such as spray diary records or declarations about pre-harvest intervals for sprays or any sulphur dioxide field additions.
Export wine grape spray schedule
If you grow grapes that are intended to be made into export wine, the 'Export wine grape spray schedule' helps you comply with the pesticide residue standards of overseas markets. The schedule is published annually by New Zealand Winegrowers for their members. You can contact them to find out how to obtain the schedule.
Wine ingredients (commodities) other than grapes: safety requirements
If you supply fruit, vegetables or other plant material, or honey used in the production of wine, you must ensure that they are free from hazards that could cause injury to human health.
If your commodities can be sold on the retail market, meaning they are suitable for human consumption, they are generally suitable for making into wine.
Winemakers may ask you to provide the following information about the commodities you supply to them:
- date of delivery
- grower details
- quantity and type of commodity received – actual or estimated
- if there was any contamination, and if so, the nature of the contamination and the steps taken to eliminate, minimise or manage it.
