Cold brew coffee! How to make your own at home

I can’t imagine a life without coffee, but during hot days i prefer a cold cup over a hot one. Yumm, iced coffee! But i’m a lover of a simple cup of black coffee as well. So i improvised and tried to make cold brew coffee myself, and i must say.. it turned out pretty good! The best part is that i had everything that is needed at home already, and i’m sure you have as well.? So lets go:

Here’s what i used:

  • a spoon
  • a large jar, one that can be closed (i used a mason jar)
  • a coffee filter
  • a chemex
  • cold water
  • ground coffee (coarsly grounded coffee will work best, similar to the consistency of breadcrumbs. With any finer grounded coffee your cold brew will turn out cloudy and dusty)

Don’t worry! If you don’t have a chemex, you can still make the cold brew 🙂 You can swap the coffee filter and the chemex with a sieve and paper towels or a thin cotton cloth (a muslin, or something similar).

– Make your own cold brew coffee –


1. Fill 1/7th part of the jar with coffee grounds.

?I worked with a 1:6 coffee-to-water ratio, this is the perfect balance between the amount of cafe?ne and the flavour. I tried several coffee-to-water ratio’s and trust me, it’s quite easy to end up shaking all day. Woops!


Step 2: Add cold water and stir.

Cover the coffee with cold water, while keeping the 1:6 coffee-to-water ratio in mind.


Step 3: close the jar and leave it in the fridge overnight or for 24 hours.

You’re almost done! Now you just have to let time do it’s job. Wait about 18-24 hours before filtering to get the best flavour.


Step 4: Filter.

If you use a chemex (or a similar filter) just like me, you just have to filter the coffee once.

If you use a sieve, cover the sieve with a cloth/ paper towels. Filter the coffee about three times, renewing the paper towels/ rinsing the cloth after each time. This way your coffee will be filtered perfectly as well.

If your coffee stays dusty after filtering a few times, your grind was too fine. Don’t throw it away, you can still drink it, or maybe use it in an iced coffee recipe.

But practice makes perfect! So the next time you try cold brew coffee, grind your coffee more coarsely.



Step 5: enjoy!

Tadaa, that’s all! Enjoy your cup of cold brew straight out of a glass or with an eco-friendly straw. 😉


Step 6: Cover what is left and store in the fridge.

I always make small amounts so that i don’t have to worry about whether the taste stays okay.. because i honestly don’t know for how long you can store this product before it goes bad. I usually make one mason jar at the time, that should be enough for three – four glasses. 🙂 Enjoy it!
