How to Make Aeropress Cold Brew
It’s hot and sunny outside. You have gotten sick of drinking watered down iced coffee. You need something smooth and refreshing to carry you through these long summer days.
That’s where cold brew comes in. It’s the perfect drink to get you through the summer, and can be made easily with almost anything available in your house.
But can you make it in your aeropress? The answer, of course, is yes.
Why make cold brew in an aeropress, you wonder? The reason is that it is a handy, versatile and affordable machine, and is quick to setup and clean. If you are a coffee nerd at all, you need to get one now!
If you are looking to skip all the work of traditional cold brewers, read on. We are going to show you how easy it is to make delicious aeropress cold brew.
This is by far the easiest cold brew I’ve ever made. It took me about 1 minute to set up and about 1 minute to finish and clean up.
The only downside is that an aeropress isn’t able to make a large batch of cold brew. You can only make 1-2 cups each time. But for 2 minutes of work, I’d say it’s worth it.
What you will need
This recipe is enough for one cup of cold brew. You can easily double it if you like. We are going to make a cold brew coffee concentrate and add water later to make a drinkable cup.
WHAT YOU NEED
This method is very similar to brewing normal coffee with an inverted aeropress.
The only differences are the ratio of coffee to water, the temperature of the water and the steep time.
How to Make AeroPress Cold Brew - Step by Step
You have everything you need and its time to make some cold brew with your Aeropress.
Here's how you do it
Step 1 - Measure out 30 grams of whole bean coffee.
Choose your coffee. Again, there are no rules as to what type of coffee you need for cold brew. It’s all about your personal preferences.
Weigh out 30 grams.
Try to measure your coffee by weight instead of volume. Different coffees will vary in weight. For example, one table spoon of coffee A might weigh 6 grams while a tablespoon of coffee will weigh 8 grams.
Step 2 - Grind coarse.
When planning to steep cold brew for 24 hours, it’s important to grind as coarse as you can, just as you might for a french press.
Grinding too fine will cause the coffee to over extract, pulling out unwanted acidity and bitterness. If you want a shorter steep time, such as 4, 8, or even 12 hours, you could play around with a finer grind size.
Grind the coffee just before brewing for maximum freshness and flavor.
Step 3 - Invert your aeropress and add coffee.
If you had your aeropress for any length of time, you’ve likely experimented with brewing inverted - that is, placing the plunger into the top of the brewer and then flipping it over.
Inverting the aeropress is important because you need the coffee and water to steep for 24 hours.
So go ahead and invert the aeropress. Set it on your scale and add the ground coffee.
Step 4 - Add room temperature water. Stir gently.
If you want to be exact - add 132 grams of room temp water.
Even though this is cold brew, it doesn’t need to actually be cold just yet. Using room temperature water and letting it steep at room temperature will produce solid results.
You don’t need to put it in the fridge to steep - this will just slow down the process further.
After adding the water, give it a gentle stir with a paddle or spoon, ensuring all the grounds are in contact with the water.
Cover the top of the aeropress with a filter or cup, to keep anything from falling into the coffee.
Step 5 - Let sit for 24 hours at room temperature.
The waiting has begun. Try to forget about the coffee. Go to work. Take a nap. Visit your grandmother. Anything to pass the time until your delicious cold brew is ready.
Avoid placing the coffee in direct sunlight. Place it in a spot where light or heat won’t affect your concoction.
Step 6 - Place a paper filter in the basket and rinse.
Congratulations, you made it through the day. After 24 hours, your coffee has been properly extracted.
Now it’s time to rinse your paper filter.
This may sound like a minor detail, but rinsing the filter before using will wash away any paper taste that might affect the coffee.
The aeropress filters are so thin that any taste coming through is unlikely, but it’s generally a good practice in coffee brewing.
Make sure to shake any excess water out of the filter.
Step 7 - Add filter to basket, screw onto aeropress. Flip onto a glass.
Once your filter has been rinsed, screw onto the opening of the inverted aeropress.
To avoid coffee dripping everywhere as you flip, place your cup, upside down, on top of the brewer. Hold the cup over the opening as you flip the aeropress over.
You can either plunge it down to finish it quickly or remove the plunger and let it drip on it’s own for a minute or two.
Before adding coffee concentrate to your glass, set your glass on the scale and tare it. Then, when the coffee concentrate has been added, put it back on the scale to know exactly how many grams of concentrate you have.
Step 8 - Clean your aeropress.
Once your coffee has been extracted, empty the grounds into the trash or compost and rinse off your aeropress.
You’ve got to love how easy it is to clean these things.
Step 9 - Finish your cold brew by adding water or milk.
Again, our current result is a coffee concentrate. It’s very strong. This is where we add water (or milk) to make a tasty, drinkable cup. I recommend starting with equal parts water to coffee, and adjusting it further if needed.
So, if you have 100 grams of coffee concentrate, I would add 100 grams of water (the same type of water you used earlier).
Top it off with a couple of ice cubes and enjoy!
Depending on your personal preference, you might want to add more or less water.
Experiment with different amounts of water. Split your concentrate equally into 4 different cups. If there is 20 grams of coffee concentrate in each cup, add 10 grams water to one, 15 grams water to another, 20 grams water to the third and 25 grams water to the last.
Each one will taste a little bit different. If you find out what ratio you prefer, you will be able to repeat your results a lot easier the next time around.
What do you think?
Was that easy or what? It looks like a lot of steps, but it really takes just a couple of minutes to make awesome aeropress cold brew. Plus, you can store it in the fridge for about 2 weeks (but why would you wait that long to drink coffee this good?)
What’s the result of such an easy process? A refreshing, smooth cup with lots of sweet cocoa notes and a full body.
The best thing about making cold brew with an aeropress is that you only use a little bit of coffee (30-60 grams). You don’t have to use an entire bag, like traditional cold brewers might require.
