Just Because You Asked, Here's How I Cold Brew Coffee

A few months ago in my "How we work" article, I mentioned the fact that I cold-brew my coffee. Since then, I've been asked a few times the method I use to transform my grounds into smooth, drinkable concentrate, so today I'm going to share my (very simple) process.

First, there are a few things you'll need:

  • Ground coffee. If you have the equipment, you can buy the beans and grind them yourself, but one of the great benefits of cold-brew is that it makes even cheap supermarket coffee taste good. So a reasonable compromise is to find a decent brand and just buy a bag of pre-ground coffee.
  • Upphetta IKEA coffee plunger. A great purchase at $14.99, the Upphetta is the perfect size for brewing a generous quantity of coffee concentrate. A lot of online guides recommend using a filter and letting the coffee drip itself clean, but using this press is much faster for similar results.
  • A second container to hold the concentrate.

Now, for the making part. First, measure out about a cup's worth of coffee and dump it into the Upphetta. I just use a regular drinking glass from the cupboard. The idea is to use one-part coffee to four-parts water.

Then, turn on the tap, making sure the water is coming out at low pressure, and place the Upphetta underneath. Fill it slowly, being sure to move the container around a little to help mix the coffee.

Let the water fill until it's directly below the bottom of the steel band of the Upphetta — the one that attaches the handle to the side. Take a spoon and stir the coffee/water mix for 10-20 seconds. Leave it uncovered (if possible) for ten minutes and then stir it again for another 10-20 seconds.

Finally, cover the Upphetta with glad wrap and a rubber band (as in the picture above), or another method that seals it. Then, leave it overnight — 24 for hours if you can. Uncover and plunger the coffee slowly — apply only the minimum force required to move the mesh downwards. Once you reach the bottom, pour the concentrate into the second container.

That's it. You can either use the concentrate immediately — one-part to two-parts milk or water — or store it in the fridge, covered. It should last a week and should provide four-five glasses, depending on how strong you like your coffee.

    24 hours for some coffee? Better taste effing amazing...

    Or:
    Instant coffee, sugar, enough boiling water to cover, stir, fill mug with milk, slam it.

    Tastes.. alright...

    Walk to coffee machine, place cup, press button.

    Wait 30 seconds, enjoy coffee.

    I used to brew my coffee because I hated the taste of instant. A friend recently put me onto coffee bags, which is pretty much just ground coffee in teabag format. Same taste but quicker and more convenient - although it costs more.

    Coffee bags contain ground coffee but the flavour actually comes from the instant coffee powder they also contain, they are just more expensive instant coffee.

    It is like drip coffee, but without the fancy glass funnels and tubes etc. nice!

    It sounds truly disgusting.

      I started cold brewing my coffee and now every time I try conventional drip coffee, it's so bitter I can't stand it. I'll never go back. Cold brew is so smooth it's hard to have that last cup of the morning. It's a little bit of work making it but soooo worth it!!

    Nice! Not many of us cold-brew people out there. My method...

    1. Use ground coffee in a percolator, using espresso-strength grounds, fill it to the top.
    2. Pour half of the 10-cup jug into another vessel, for me its my large Tupperware mug.
    3. Stir in approx 4 tablespoons of sugar while hot for maximum absorbency.
    4. Leave in the fridge for 12 hours.
    5. Do not taint with milk. ;)

    10 cup percolator is suitable for 2 coffees.

    i like making cold brew coffee but I do find I go through coffee at a much higher rate.
    What i usually do when I'm on a cold brew bender is similar to above with the slight variation that I just put it all in a jug and then use my aeropress to filter out the coffee grounds. i found that using a french press usually requires a lot of pushing because of the large amount of grounds in there.

    Also theoretically (though honestly I don't think I really notice all that much of a difference) it's advisable to use filtered water
