🍷 Acidity
The fresh tartness of wine that makes your mouth water.
Acidity is the fresh tartness of wine that makes the mouth water. Every wine needs it: without it, a wine feels flat and heavy. The main acid in wine is tartaric acid; there are also malic, lactic, citric and acetic acids.
Acidity depends on climate and grape variety. In cool places berries ripen more slowly and keep more acid. In hot places there is less. High-altitude vineyards also keep acidity thanks to cold nights. It is measured by acid content and by pH.
If there is too much acid, the wine is deacidified, and if too little, it is acidified. Acidity is one part of the balance of a wine, next to sweetness, alcohol and tannin. Good acidity helps wine keep and pair with food: it refreshes against fatty dishes. That is why acidity is an important word in describing wine. Acidity should not be confused with the sourness of spoiled wine or with bitterness: it is a pleasant refreshing note.
