In the case of sake, the acidity (also known as total acidity) is a measurement of the acid content in the sake. Why is the acidity important? Well, acidity (along with alcohol level and sugar content) is one of the key measurements we look at to evaluate balance in sake. Acidity can express itself as a counterpoint to the residual sugars in sake and can sometimes express itself as dryness or tartness on the palate. It is important to note that in general, sake has a substantially lower total acid content than wine does. This gives sake an overall softer impression with less of the acidic ‘bite’ you might find in some wines.
The total acidity is expressed on a scale with most sakes falling between 1.0 and 2.0,
