2 .Place the coffee into the filter basket and insert it into the Hario Mizudashi glass brewer.
3. Start adding a room temperature water to the grounds slowly making sure you don't overflow the filter basket. Add a total of 1000 mL water.
4. Refrigerate the pot for 16 - 24 hours depending on the desired strength. After the time has elapsed remove the filter basket with grounds.
