Sip by sip - each drop gives you that authentically slow-drip brewed coffee flavour. Get your Java ready in a mere sixty minutes and just relax, no need to fiddle with the speed. This drip-style cold brew device has no speed control - when you add H2O to the top bowl, it drains and slowly drips from the double slits in the dripper. All the water will have dripped in an hour's time without a fuss - you get easy access to good-tasting cold brew coffee! Assembled with strict Japanese quality control standards.
