We've all seen the Tiktoks, Instagram posts, and Pinterest pins—coffee in a mason jar, with a perfect little label. It looks so rustic and refreshing, and we all want to jump on the bandwagon.

Sometimes trends like these that look so perfect on social media are just done for aesthetic purposes, but are impractical—taking too much time and effort.

But fortunately, this isn't one of those! In fact, making cold brew coffee in a mason jar couldn't be easier, and it's a fun way to make delicious cold brew all summer long.

What You Need to Make Cold Brew in a Mason Jar

All you need is some coarsely ground coffee, a mason jar, a large bowl, and a way to filter the coffee once it's brewed.

For the filter, you can use a standard paper coffee filter, cheesecloth, or a reusable metal mesh filter. You can even use a standard kitchen strainer—just make sure it's big enough to fit over the bowl, and that the mesh is fine enough to catch all the coffee grounds.

To help you prep, we've selected some items on Amazon.

As for the coffee, you can use any type of beans you like. Just make sure to grind them coarsely, since finer grounds will make for a stronger, more bitter brew.

How to Brew Coffee in a Mason Jar

  1. Start by adding 1/2 cup of coarsely ground coffee to your mason jar.
  2. Pour in 2 cups of cold water, and stir gently to combine.
  3. Cover the jar with a lid or piece of cheesecloth, and let it sit in the refrigerator for 12-24 hours.
  4. After the brew time is up, remove the lid or cheesecloth and filter the coffee through your filter of choice into the large bowl.
  5. Rinse out the mason jar to remove any grounds that are still in the jar, and pour the brewed coffee from the bowl back into the jar.
  6. Cover the jar and store it in the fridge for up a whole week
  7. To serve, mix the cold brew concentrate with water, milk, or ice cubes to taste.


  • You can use multiple mason jars to make a larger batch of cold brew concentrate, or even brew different kinds of coffee together to create your own unique blends.
  • The quart size jars are the perfect size for making cold brew concentrate, but you can also use pint-sized jars if you want to make smaller batches (and if you're really good at not spilling things.)
  • If you're using a kitchen strainer to filter your coffee, line it with a coffee filter or cheesecloth to prevent pesky grounds from getting through.

Enjoy making delicious cold brew in a mason jar all summer long! Just don't forget to share your pictures of it on social media.

(Don't worry—if your friends get too jealous, just send them this article.)
