This exceptional glass pot cold coffee brewer has a nylon screen filter inside and makes an ideal full-immersion cold brewer. The result is coffee that is heavy and highly caffeinated but low in acidity or harsh roast notes. Unlike many other cold brewers on the market, which produce a coffee concetrate, the Mizudashi produces a highly caffeinated, deliciously cold brewed coffee that you can drink without diluting. It’s an exceptional cold brewer. If you’re looking for a simple, affordable, cold brewer you’ll enjoy the Hario Mizudashi!
