Immersion and time, create an earthy, mellow and low acidity brew



Cold brewing first began in Kyoto, way back in the 1600s. The simple process of immersing coffee in cold water and letting it steep overnight, resulted in a concentrate that is smooth, mellow with very little acidity or bitterness.

There are many different techniques to make Cold brew: Toddy Cold Brew, or The Cold brew tower. We will use the Cold Brew bottle, a simple flask that’s designed to be used at home.

The Cold Brewer uses the Immersion technique of brewing.
