• It makes cold coffee faster: it takes about 10 minutes including the time to boil water.
  • The flavors are more robust than a cold brew.


  • It makes just one to two servings at a time.
  • A little more labor-intensive than a cold brew and more work to make a big batch the night before.

Equipment You Will Need for Japanese Iced Coffee

If you are already making hot coffee with a dripper, you will not need to buy special gear.

Coffee Beans that We Love

In conclusion, if you are a coffee lover and especially iced coffee, please give Japanese iced coffee a try. We recommend using delicate beans that are full of flavors. If you live in the bay area try the beans from Sightglass, Ritual, Four Barrel, or Blue Bottle.

Another bay area coffee roaster we highly recommend and offer truly extraordinary coffee beans is Helio Roast. It’s run by a former university professor named Kern Trembath. There are a few unique characteristics about Helio Roast:

  1. They use electric roaster powered by solar energy.
  2. They only roast the beans after you order them. You decide on the type of beans you want and roast level, and your coffee bean is handcrafted just for you.

There is nothing like freshly roasted coffee beans, the resulting coffee is simply excellent. Kern has generously offered all JOC readers 10% discount if you use the code “JUSTONECOOKBOOK” during checkout (we do not make any money from your order, we like to support small local businesses).

We’ve tried Sumatra Toba Batak, No Fear, and Sumatra Lintong Pak beans roasted at Full City+ level and they were amazing.

Lastly, if you travel to Salt Lake City, stop by and purchase some beans from John at the Salt Lake Roasting Co. John has an amazing selection of coffee beans from all over the world and we always stop by for some coffee and pastries when we go skiing in Utah. He also ships his delicious beans so you can purchase them online.

Recipe Notes

Coffee beans: Any coffee works well.  Our preference is a light to medium roast with bright flavors.  1 Tbsp is roughly 5 grams but each coffee grinds weigh differently but close.


Hot water: It should be between 195 F (91 C) and 205 F (96 C).  The closer to 205 F (96 C) the better. Boiling water (212 F / 100 C) should never be used as it will burn the coffee.
