Wine tasting techniques involve several steps to fully appreciate the characteristics of a wine. First, observe the wine's color and clarity by holding the glass against a white background. Next, swirl the wine gently to release its aromas, then take a moment to inhale deeply, identifying different scents. After assessing the aroma, take a small sip and let the wine coat your palate. Pay attention to the flavors, acidity, sweetness, and tannins. Finally, consider the finish, or how long the flavors linger after swallowing. This process helps in understanding the complexities of different wines, such as those from regions like Bordeaux or Napa Valley.
