What is the typical range of pH in a wine?

• A. 2-3
• B. 3-4
• C. 4-5
• D. 5-6

Answer: (B)

pH is a measure of hydrogen ion activity, a logarithmic scale that tells how acidic a solution is. In wine, acidity comes mainly from tartaric and other acids, and the balance between this acidity, flavor, and stability is what we’re aiming for. That balance typically lands in the mid-range of the scale, around 3 to 4. If pH were much lower, the wine would taste very tart and can be hard to balance; if much higher, the wine can taste flatter and be less stable color- and microbiologically. So, the typical range you’ll see in wine is around 3 to 4.
