How to Make AeroPress Cold Brew: A Step-by-Step Guide

I've always been a fan of cold brew coffee for its smooth, rich flavour. But, let's face it, waiting hours for it to steep can be a bit of a drag. That's where the AeroPress comes in handy. It's not just for hot coffee; it can whip up a delicious cold brew in a fraction of the time.

So, if you're like me and prefer making your coffee at home rather than queuing up at a coffee shop, you're in the right place. I'll show you how to make an AeroPress cold brew that'll rival any café creation. Fast, simple, and utterly delicious – let's dive in.

Choosing the right coffee

When diving into the world of AeroPress cold brew, the coffee selection is paramount. It's not just about grabbing any beans off the shelf; it's about finding the perfect match to enhance your cold brew experience. Let's discuss the nuances of choosing the right coffee for your AeroPress cold brew.

Understanding Coffee Roasts

The roast level of your coffee beans significantly affects the taste of your cold brew. Here's a quick breakdown:

Coffee Grind Size Matters

The grind size of your coffee beans is crucial when using the AeroPress for cold brew. You're looking for a medium to coarse grind: too fine, and you risk over-extracting your coffee, leading to a bitter taste; too coarse, and your brew may end up under-extracted, lacking in flavour. Aim for a consistency similar to sea salt for the best results.

When I'm picking coffee for my AeroPress cold brew, I tend to lean towards a medium roast single-origin for its distinctive taste that really shines at cooler temperatures. However, experimenting with different coffees can be a rewarding journey, leading you to discover what best suits your palate.

Remember, the best coffee for your AeroPress cold brew is the one that aligns with your taste preferences. Don't be afraid to experiment with different roasts, grind sizes, and origins to find your perfect match.

Grinding your beans

When it comes to making AeroPress cold brew, grinding your beans correctly is just as crucial as selecting the right type of beans. I've found that the grind size can significantly affect the extraction process, and ultimately, the taste of your cold brew. So, let's dive into the essentials of grinding your beans for that perfect cup of AeroPress cold brew.

First off, you'll want to aim for a medium to coarse grind. This is because a finer grind might lead to over-extraction, making your cold brew taste bitter, whereas too coarse a grind could result in a weak, under-extracted brew. Through trial and error, I've discovered a sweet spot that works wonders.

Here's a simple and easy-to-follow guide for grinding your beans:

  1. Measure about 17g (for a single cup) of your favourite coffee beans. Adjustments may be needed based on your personal taste preference.
  2. Set your grinder to a medium-coarse setting. If your grinder uses numbers, start around a 7 on a scale of 1 to 10, with 10 being the coarsest.
  3. Pour the beans into your grinder, and grind away. Shake the grinder gently if it helps to achieve a more consistent grind size.
  4. Check the grind. The texture should resemble coarse sea salt, neither too fine nor too chunky.

Remember, consistency is key. An inconsistent grind can lead to an uneven extraction, which might not give you the smooth, balanced flavour you're seeking in a cold brew.

I always recommend experimenting with different grind sizes to find what best suits your palate. It’s part of the fun in crafting the perfect AeroPress cold brew at home. Just make sure not to grind the beans too far in advance. Freshly ground beans will always yield the best flavour, ensuring those vibrant, nuanced notes come through vividly in your brew.

Brewing with the AeroPress

After you've nailed the grind size for your beans, it's time to move on to the brewing process itself, which is surprisingly straightforward with the AeroPress. The AeroPress's versatility not only allows for quick and hot coffees but also shines when it comes to cold brew. Here's how I do it:

  1. Prepare the AeroPress: I start with my AeroPress in the inverted position. This means the plunger is at the bottom, and I'm working with the brewing chamber up top. Make sure it's stable to avoid any spills.
  2. Add Coffee: For a robust cold brew, I use about 30g of my medium to coarse ground coffee. It might seem like a lot, but trust me, it's worth it for the rich, full flavour.
  3. Add Water: Next up, I pour in 120ml of cold water. Unlike hot brews, you don't need to worry about temperature here, just use water straight from the fridge or at room temperature.
  4. Stir: Give the mixture a good stir to ensure that all the grounds are wet. This helps with even extraction, which is key for a delicious brew.
  5. Let It Brew: The magic happens during the wait. I let my AeroPress sit for about 12 hours. This slow brewing process is what creates the smooth, rich taste characteristic of cold brew.
  6. Press: After the wait, it's time to press. Place your AeroPress over a sturdy cup or jug and gently press down. Take your time with this step to avoid agitating the coffee too much.
  7. Dilute (Optional): The resulting coffee is a concentrate, so you may want to dilute it with some water or milk according to your taste.

Using the AeroPress for cold brew not only makes a delicious cup of coffee but also offers an opportunity to experiment with different brewing times and coffee-to-water ratios. Each variable you adjust can lead to a unique taste, allowing you to tailor your brew to your exact preferences.

Making the cold brew

I've covered why the AeroPress is a must-have for coffee aficionados, especially for those who relish the smooth taste of cold brew. But how exactly do you make cold brew with an AeroPress? It's simpler than you might think. Let's dive into the steps I follow to ensure a perfect cup every time. Remember, the beauty of AeroPress is its flexibility, so feel free to tweak the process to suit your taste.

What You Need

First, let's talk about what you'll need:

The Brewing Process

Follow these steps to brew your perfect cup:

  1. Prepare the AeroPress in the inverted position. This means flipping the AeroPress so that the plunger is at the bottom and the entire assembly stands on it.
  2. Add the coffee. I use about 17g of coffee, which is roughly one AeroPress scoop. The grind should be coarse, akin to sea salt. This consistency is crucial for a smooth extraction.
  3. Add cold water. Pour in about 200ml of cold water. The general rule is a 1:12 coffee-to-water ratio, but feel free to adjust based on your preference.
  4. Stir for an even extraction. I give it a good stir for about 10 seconds to make sure all the coffee grounds are fully saturated.
  5. Let it brew. Place a sealed container or pitcher on top of the AeroPress (still in the inverted position) and securely put it in the fridge. Let it steep for about 12 hours. This slow brewing at a cold temperature extracts the flavors gently, reducing acidity and bitterness.
  6. Press the coffee. After your brew time is up, take the AeroPress out of the fridge, flip it onto your cup or pitcher (carefully, to avoid spills), and press down slowly. This step should take about 30 seconds.

And voilà, you've got yourself a delicious AeroPress cold brew concentrate. If you find it too strong, dilute it with a bit of cold water or milk to taste.

Enjoying your AeroPress cold brew

Once you've patiently waited for your AeroPress cold brew to reach its peak flavour after those long 12 hours, it's finally time to enjoy it. I've found that the best part about making your own cold brew at home, especially using an AeroPress, is the absolute control you have over the strength and flavour of your coffee. Here’s how I typically enjoy my AeroPress cold brew, with a few suggestions to personalise your coffee experience.

First thing's first, the serving. Cold brew coffee from an AeroPress is quite concentrated, so you might want to dilute it with water. I usually go for a 1:1 ratio of coffee to water, but feel free to adjust according to your taste.

  1. Fill a tall glass with ice cubes.
  2. Pour the cold brew over the ice, filling half of the glass.
  3. Add cold water or milk to fill the rest of the glass.

The beauty of AeroPress cold brew is its versatility. Whether you’re after a sharp, energising drink to kickstart your day, or a sweeter, creamier beverage for a leisurely afternoon, the AeroPress has got you covered. And remember, the key to a great cold brew is experimentation. Don't be afraid to adjust ratios and ingredients until you find your perfect cup.
