Hario Mizudashi Brew guide
Step 1
Grind coffee to a medium - coarse level (finer for a light roast, coarser for a dark roast)
For lighter roasts, it should be finer than the coarseness used for a French press, but more coarse than what is used for drip coffee.
Step 2
Place a filter in the basket, and pour in the grounds.
Step 3
Completely saturate the grounds with 1,150 to 1,200 ml of filtered water. Use circular motions to ensure all grounds are saturated.
Step 4
Cover your brewer and place in the refrigerator. This will result in a crisp brew.
Step 5
After 18-20 hours, open the brewer, remove the filter, and store in the refrigerator.
