Sake is predominately composed of water — which is why the water source is the most critical component for premium brands. Origami Sake sources our water exclusively from the Ouachita Mountains in Hot Springs, Arkansas – a town famous worldwide for its water. The Ouachita Mountain aquifer in Hot Springs provides pure, naturally filtered water that is low in sodium and iron, possesses a perfect pH, and is naturally infused with minerals that are perfect for premium sake production. Origami uses better water. You get better sake.
