品尝 (pǐn cháng) means 'to taste, to sample' and is used for deliberately tasting food or drink to evaluate its flavor, often in a formal or appreciative context. It is more refined than the everyday word 尝 (cháng), which simply means to try a small amount. 品味 (pǐn wèi) goes further, emphasizing savoring and appreciating aesthetic qualities, not just flavor.
