Yield: The quantity of grapes or wine produced measured in tons per acre or hectoliters per hectare. Although it is true that overcropped vines with high yields produce less-concentrated grapes, it is not true that lower yields always mean higher quality. Different soils, vineyards and varieties are able to successfully carry different levels of crop.

产量：指单位葡萄园内葡萄或生产的葡萄酒的数量，通常用吨/英亩或百公升/公顷表示。尽管过度种植高产葡萄藤会降低葡萄的浓度是事实，但低产量并不意味着有高品质的葡萄。不同的土壤、不同的葡萄园和不同的葡萄品种在相应不同程度的种植水平下都能取得成功。
