Hario Cold Brew Jug

Making cold brew coffee

BREW TIME: about 16 hours

Hario’s elegant glass brewer is the perfect instrument for mastering the method of ​Mizudashi​, Japanese for “infusing with cold water.” Our recipe creates a cold brew concentrate and calls for nothing more than ground coffee, filtered water, and time. The fine metal filter requires a slow pour. Over the course of three minutes, you’ll stir the brew bed constantly to ensure full immersion.

What you’ll need

1x Hario cold brew jug1x digital gram scale145g coffee (ground like coarse salt, 20 setting on Virtuoso+)
1x timer
1x stirring utensil
1150g room-temperature filtered water


  • Place the cold brew jug, with the metal filter inserted but without the lid, onto the digital scale.
  • Add the ground coffee into the metal filter. Zero out the scale.
  • Pour the water very slowly into the carafe while stirring the coffee. This step may take upwards of 3 minutes.
  • Place the lid on the carafe. Leave the cold brew jug to brew at room temperature for 16 hours.
  • Remove the filter. Put the lid on the bottle and store in refrigeration. The cold brew concentrate will stay fresh for up to 7 days in a refrigerator.
  • Dilute your serving with equal parts filtered water and enjoy! *Pro tip: We prefer a 1:1 dilution with filtered water and ice, but the potential variations are unlimited. Feel free to dilute with milk or non-dairy alternatives if you take your coffee that way.
