Equipment
- 1 half gallon mason jar
- cheese cloth
- 1 large spoon
- 1 funnel
Ingredients
- 3 cups coffee beans coarse ground
- 7 cups water
Instructions
Brew
- Add 3 cups coffee beans coffee to a half-gallon mason jar.
- Add 7 cups water to the jar.
- With a large spoon, stir to wet and incorporate the coffee grounds into the water.
- Cover the mason jar with 2 part lid. Steep on the counter at room temperature or in the refrigerator.
- Allow the to coffee steep for 12-24 hours. I recommend trying at the 12-hour mark. I personally think 16-18 hours is best. The longer you steep, the deeper the flavor will be.
Strain
- The next day, remove the mason jar from the refrigerator. Use a large spoon and scoop out as many of the coffee grounds at the top and discard.
- Place a funnel on top of a clean mason jar. Add a cheesecloth-lined mesh stainer over the funnel. Pour the cold brew over the cheesecloth to separate the grounds from the cold brew. Another option is to use a French press to separate the grounds from the brew. There will be roughly a quart of cold brew concentrate.
Serve
- To serve, use 1 part concentrate and 3 parts water. Add ¼ cup of concentrate, ¾ cups of water to a glass, and top with ice.These are the ratios that I use; feel free to use more or less water for your personal preferences.
- Add cream, milk, or your favorite coffee creamer and enjoy!
Store
- Pour the cold brew concentrate into a container with an airtight lid. Use a container that will leave as little headspace as possible to reduce the amount of air exposure.Cold brew will have the best flavor if used within the first week but can be stored for up to two weeks.

Tips
- I suggest grinding the beans to a coarse grind right before brewing to have the freshest flavor and best brew. Whole roasted coffee beans contain carbon dioxide, which prevents oxidation and the flavor from becoming stale. Once ground, more of the surface area is exposed to oxygen, causing loss of flavor.
- Freeze cold brew concentrate into ice cubes so your iced coffee drink isn't watered down as the ice melts.
- Don't throw the grounds away! Add to your compost pile or use for acidic-loving plants.
