Rice wine is an alcoholic drink made from the fermentation of rice starch. Rice brew typically has a higher alcohol content than wine made from fruits such as grapes.
Although wine was commonly used in the Vedic period, Buddhist principles forbid its consumption:
"Let the house-holder, who approves of this Dharma, not give himself to intoxicating drinks, let him not cause others to drink, nor approve of those that drink, knowing it to end in madness." (Dhammika Sutra).
There are five commandments binding on Buddhists, laymen and Bhikkus alike and one of them is:
"Let not one drink intoxicating drinks."

"I take the vow to abstain from intoxicating drink, which hinders progress." (Mohavagga 1-12).
