A wine critic is a professional who evaluates and reviews wines, providing insights on their quality, flavor, and overall characteristics. They often taste a wide variety of wines from different regions and vintages, using a systematic approach to assess aspects like aroma, taste, and finish. Their reviews can influence consumer choices and the wine market. Wine critics typically publish their findings in magazines, websites, or books, and may also participate in competitions or tastings. They often use a scoring system, such as the 100-point scale, to rate wines, helping consumers understand the relative quality of different bottles.
