The average alcohol content by volume in sake is around 15%. This is slightly higher than wine, but since most sake has a clean, smooth flavor, you may unintentionally overdo it.

Oftentimes, a glass of water is consumed alongside sake in order to alleviate the effects of alcohol. Drinking some water with your sake refreshes the mouth and helps prevent inebriation.

The liver needs water to break down alcohol, so the notion of a “cup of sake, a cup of water” makes perfect sense.
