Cold Brew using a Cafetiere
What is cold brew coffee?
Cold brew is a coffee that is steeped over a long period of time in cold water. Here time replaces heat when it come to the extraction. So what's the benefit of brewing your coffee in cold water? Essentially the acids that can be released in hot coffee which can create more bitter tones are simply never released curing cold brewing, resulting in a smoother sip.
What coffee to use?
Basically use the coffees you normally like. As a guide - African coffees produce more fruity notes and Central American coffees have chocolate notes, but any of our fabulous coffees are worth experimenting with!
How much coffee should you use? The answer to this question will vary depending on whom you ask. The short answer is more than you would for regular brewed coffee. If you do not want to deal with maths or scales, just double the amount of the coffee you normally use when making hot Cafetiere coffee, job done!
1. Grind the coffee
You can use a medium to coarse grind when brewing cold brew coffee in a Cafetiere. I use a more coarse grind, but either will work. If you find the coarse ground cold brew is too weak, tighten up your grind. If the medium grind is too strong, you can either add more water or loosen up the grind, see our grind guide for more information.
3. Add the ground coffee and water to the Cafetiere
Just like you would for a regular Cafetiere, add the ground coffee to the bottom of the brewer. Only this time instead of hot water off the boil, you will add room temperature or cold water.
TOP TIP: Filtered water seems to have the best results.
You will want to make sure that all the coffee grounds are making contact with water. Stir the coffee slowly. Try and cover as much of the coffee with water as you can.
5. Cover and set aside for 12+ hours
You can now cover the Cafetiere (without the plunger in) however you like. A small plate or cling film are two ideas. You could use the plunger filter if nothing else is to hand, just make sure you only press down enough to hold it into place. You do not want to press the filter down until the brew is finished, which is still 12+ hours away.
There is a debate about whether you should cold brew the coffee on the kitchen counter or in the fridge. To be honest - either is fine, however I prefer the counter top as I think it brews faster, which means that if I need to cut the brew cycle short by an hour I can. However, if I was going to be away for much longer than 12 hours, I’d brew it in the fridge (just make sure it is well covered!).
6. End the brewing process and serve
SLOWLY push the plunger down to get a clean tasting French Press. Strive for a 30-second plunge (cue the lift music!). At this point, you can transfer the coffee to a Kilner style jar for storage or serve it up.
TOP TIP: The Cafetiere is not the greatest of filters and can produce coffee grounds in the drink - so you can filter the coffee again if you like. Place a paper coffee filter over a jar and slowly pour the coffee. This will catch any loose grounds.
