Tasting acidity in wine gives you the sense of tasting something tangy, something sour. It causes you to salivate and you can feel it at the back of your tongue, your throat and traveling down your esophagus as you swallow. Acidity also helps wine to age. If a wine is high in acid it has the potential to age longer than usual, particularly with white wine. See our take on acidity in this episode of The Sommelier’s Notebook, exclusively on SOMM TV.
