Sake Acidity – Sando ( 酸度 )

Article discusses sake acidity (sando).

The acidity of a sake or its sando is a measure of how much base liquid is needed to neutralize 10ml of sake. Acidity in sake balances its sweetness. The sweeter the sake the higher its acidity can be without being sour or annoying. In general the higher acidity the thinner the sake will seem. However, as with all the characteristic parameters of sake, we cannot say that a sake with a high acidity level will seem thin, only thinner than if it had lower acidity.

Acidity levels tend to range from 0.8 to 1.7. As we saw previously, the nihonshudo values (SMV) tend to be between -5 and +10. Using these two metrics together is more useful than individually. Recall that the more negative the nihonshudo value the sweeter it is and the more positive the dryer it is. So producing a sake with SMV -4 and acidity of 1.7 (two extremes) could create a heavy dry sake; that’s right, dry. This is because the acidity balances out all of the sweetness. We must keep in mind that these are only trends and not absolutes. In the same way, if we produce a sake with high SMV of +7 and a acidity of 0.8 may be sweet and thin or watery.
