Using Aeropress Paper Filters for Cold Brew – A Step-by-Step Guide

Cold brew is a favorite for coffee lovers who crave a smooth, low-acid, and refreshing cup—especially during warmer months. While traditional cold brew methods involve steeping coarse grounds in water for 12–24 hours, the Aeropress offers a surprisingly quick and efficient alternative for producing small-batch cold brew concentrate. The key to a crystal-clear, sediment-free result lies in using fresh Aeropress paper filters.

In this guide, we’ll walk you through a simple Aeropress cold brew recipe that leverages the fine filtration of paper filters to yield a clean, flavorful concentrate. You’ll also discover which Friedhats coffees shine brightest when brewed cold, and how a few tweaks to your technique can transform your morning routine.

Why Use Aeropress Paper Filters for Cold Brew?

Standard cold brew methods often rely on coarse mesh filters or cheesecloth, which can let fine coffee particles slip through, resulting in a cloudy or gritty drink. Aeropress paper filters trap these fines, giving you a silky-smooth cold brew that rivals any café offering. The micro-filtration also prevents over-extraction by removing oils and sediment that can become bitter during long steeping.

Another advantage is speed. With an Aeropress, you can produce a concentrated cold brew in under 5 minutes of active work, then dilute it to taste. This makes it ideal for those who want fresh cold brew on demand without planning a day ahead. Plus, using fresh Aeropress paper filters ensures your brew stays free of stale flavors—important when you’re not heating the water.

• Aeropress paper filters remove nearly all sediment, leaving a brilliant clarity.
• Cold brew made with paper filters has a cleaner mouthfeel compared to metal-filtered methods.
• Easy cleanup: just rinse the plunger and discard the puck—no sticky carafes to scrub.

Step-by-Step Aeropress Cold Brew Recipe

This recipe uses the inverted Aeropress method to prevent dripping before brewing. Start by inserting the plunger about 1 cm into the chamber and flipping the Aeropress so the cap end is facing up. Place one fresh Aeropress paper filter into the cap and rinse it with cool water to remove paper taste.

Add 30 grams of coarsely ground coffee (think French press grind—like sea salt) to the chamber. Slowly pour 200 grams of room-temperature filtered water over the grounds, ensuring all coffee is saturated. Stir gently with a paddle for 10 seconds. Let steep for 4 minutes, then flip the Aeropress onto a mug and press firmly. You'll get about 150–180 ml of concentrate. Dilute with equal parts water or milk, or pour over ice for an instant cold brew.

• Use a 1:6 to 1:7 coffee-to-water ratio for concentrate.
• Room-temperature water (20–22°C) works best—avoid cold water directly from the fridge.
• For a stronger brew, increase steep time to 5 minutes.

Best Friedhats Coffees for Cold Brew

Not all coffees are suited to cold brewing. The low extraction temperature emphasizes sweetness and fruity notes while muting acidity. Light-roasted single origins with complex flavor profiles shine. One standout is the Rwanda Mahembe #5 Filter, which offers vibrant red berry and stone fruit notes that translate beautifully into a refreshing cold brew. Its clean, tea-like body benefits from paper filtration, highlighting its delicate characteristics.

For a bolder, more experimental cold brew, try the Costa Rica Aquiares Anaerobic. This coffee’s fermentation-driven flavors of tropical fruit and dark chocolate become even more pronounced when steeped cold. The paper filter tames any residual funky notes, leaving a velvety, well-rounded concentrate. Both coffees are available as whole beans, allowing you to grind fresh for each batch.

Tips for Perfecting Your Aeropress Cold Brew

Grind size is crucial: too fine and you’ll clog the filter and over-extract; too coarse and your brew will be weak. Aim for a consistent coarse grind, similar to what you’d use for a French press. If you’re using a blade grinder, pulse in short bursts to avoid creating fines.

Always use fresh, high-quality water. Since cold brew is less forgiving than hot extraction, any off-flavors in the water will be noticeable. For the cleanest result, try diluting your concentrate with sparkling water for a spritzy cold brew soda—add a slice of orange for a Mediterranean twist.

• Pre-wet the paper filter to reduce paper taste and help it sit flat
• Store concentrate in the fridge for up to a week in a sealed glass jar
• Experiment with different Friedhats offerings: the Uganda Nyabirongo Washed also makes an excellent clean, chocolatey cold brew
