Cloudiness: Lack of clarity to the eye. Fine for old wines with sediment, but it can be a warning signal of protein instability, yeast spoilage or re-fermentation in the bottle in younger wines. Cloudiness may also represent a deliberate choice by the winemaker not to filter a wine.

浑浊：视觉上的不清晰感。 对有沉淀的老酒而言是可以的，但是对年轻的葡萄酒而言，浑浊是葡萄酒蛋白质不稳定、酵母腐坏或者瓶子里重新发酵的一个警告信号。浑浊也可能是酿酒师深思熟虑后，不对酒进行过滤的一种抉择。
