Supplying grapes and other ingredients
If you supply grapes, other plant material or honey for making wine, there are food safety requirements you need to meet.
Requirements for all commodity suppliers
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 also find MRLs of pesticides in MPI's MRL database. This covers limits for a variety of markets including New Zealand.
Requirements for suppliers of grapes
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.
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.
Requirements for suppliers of commodities other than grapes
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.
