The certification criteria for wines bearing the AMW brand under the licence agreement must be made from grapes 100% grown in Marlborough and bottled in New Zealand. The grapes must 100% be from vineyards that are part of a recognised sustainable viticultural programme. The grapes must be grown at an appropriate cropping level with the prime objective of enhancing quality and the Marlborough name. If the grapes used to produce the certified wine do not comply with the cropping level, then it can be tasted by a panel for acceptance.
