How to Make Cold Brew - Detailed Guide

The first time I heard about cold brew coffee, I was quite skeptical. How could you make good coffee without hot water?

After all, heat seems an intrinsic part of the process of making good coffee. In addition, the process of cold-extracted coffee seemed suspiciously simple to me, it is enough to mix cold water and ground coffee, so that, after a few hours ... we get good coffee?! I believed that it wouldn’t work, and that the result would inevitably be a tasteless and watery coffee.

But it works, and what a good end product! The result is a less acidic coffee with a greater natural sweetness; Due to the fact that the extraction is carried out at a low temperature, certain elements responsible for the bitterness of the coffee are left out. What you get is a different flavor profile; deeper, smoother and sweeter, than that obtained from the extraction in hot. Let’s get started with the instructions!

Cold Brew Instructions 

What you’ll need:

  1. 100g of Ronita Coffee
  2. 700ml cooled water (preferably filtered)
  3. Cold Brew Pot 
  4. Optional: 40ml (per serve) of sweetened milk (2 parts full cream milk, 1 part sweetened condensed milk)


  1. Add the ground coffee to the empty pot
  2. Add 700ml of cool water 
  3. Place the pot in the fridge and brew it at least for 12 hours
  4. After 12+ hours, filter the contents of the pot using a filter, for which you can use a coffee filter, or a cheesecloth.

Ready to serve:

  •  In a glass, add ice cubes, one part cold brewed coffee and one part cold water.
  • Flavour your beverage as you prefer (sweetened milk,sugar, maple syrup, etc.).
  • For a less intense flavour, simply dilute the COLD BREW concentrate more by adding more cold water to your beverage. Enjoy!

Key tips for making cold brew

The procedure is really simple, and the key element to obtain a good extraction is time - it takes at least 12 hours for a complete extraction at room temperature, but it is best to do extractions of 18 or 24 hours. We would advise not to rush this process.

Another point to take into account is the size to which the coffee has been ground, to make cold brew coffee the ideal is to grind the coffee rather coarsely, which will make the subsequent filtering process easier, and the resulting coffee be more crystalline.
