Browning: Describes a wine's color, and is a sign that a wine is mature and may be faded. A bad sign in young red (or white) wines, but less significant in older wines. Wines 20 to 30 years old may have a brownish edge yet still be enjoyable.

褐变： 形容葡萄酒的颜色，是葡萄酒成熟或者是衰退的标志。对年轻的红（或白）葡萄酒而言，这是一个不好的迹象，但对老酒而言就没那么重要了。20年到30年的老酒可能出现褐色的边缘，但却依然令人愉悦。
