Perfect Iced Coffee with the Sipologie Chemex

There’s nothing quite as refreshing as a perfectly brewed iced coffee, especially on warm days. Whether you’re looking for a chilled morning pick-me-up or an afternoon energy boost, the Sipologie Chemex offers a fantastic way to brew a smooth, flavorful, and well-balanced iced coffee. Unlike traditional cold brew, this method preserves the coffee’s bright acidity and complex notes, making each sip a delight.

Why Use the Chemex for Iced Coffee?

The Chemex is known for its ability to highlight the natural flavors of coffee while maintaining a clean and crisp profile. Here’s why it’s an excellent choice for making iced coffee:

  • Enhanced Flavor Clarity: The Chemex brewing method removes bitterness while preserving the coffee’s intricate flavor profile.

  • Adjustable Strength: You can control the coffee-to-water ratio, ensuring a strong brew that won’t taste watered down.

  • Aesthetic Appeal: The elegant design of the Chemex makes brewing feel like an art, turning your coffee ritual into a visual experience.

Now, let’s dive into the step-by-step process of making the perfect iced coffee.

How to Make Iced Coffee with Chemex :

Step 1: Ice the Chemex

Start by adding ice cubes to the Chemex before brewing. This helps cool the coffee immediately as it drips, locking in its full flavor without over-extraction.

How much ice should you use?

  • A good rule of thumb is to use one-third of the final coffee volume as ice. If you’re making 250ml (8 oz) of iced coffee, use around 80-100ml of ice.

  • Pro tip: Avoid overfilling with ice to prevent excessive dilution

Step 2: Heat Your Water

Water temperature is crucial when brewing coffee, as it impacts extraction. Heat your water to around 95°C (203°F)—just below boiling.

Why is this important?

  • If the water is too hot, it can extract bitter compounds.

  • If it’s too cool, the coffee may be under-extracted and taste weak.

  • Pro tip: If you don’t have a thermometer, let boiled water sit for 30 seconds before pouring to achieve the right temperature

Step 3: Prepare and Bloom the Coffee Grounds

  • Use 15g of freshly ground coffee for every 250ml of water.

  • If possible, grind the coffee to a medium-coarse consistency (similar to sea salt).

  • Place the coffee grounds in your Sipologie steel filter inside the Chemex.

  • Pro tip: You’ll notice bubbles forming on the surface—this is CO₂ escaping, helping the coffee extract evenly

Blooming the Coffee : 

Before fully brewing, pour about 30-50ml of hot water over the coffee grounds and wait for 30 seconds. This allows the coffee to “bloom,” which releases trapped gases and enhances the final flavor.

Step 4: Brew Your Coffee

After blooming, slowly pour the remaining hot water in circular motions over the coffee grounds. This ensures an even extraction and balanced flavor.

  • Pour in slow, controlled pulses rather than all at once.

  • Allow the coffee to drip through completely before adding more water.

  • Stop once you’ve reached your desired amount—keeping in mind the ice in the Chemex will further dilute the coffee.

  • Pro tip: If you prefer a stronger iced coffee, slightly reduce the amount of water used during brewing.

Step 5: Swirl and Serve

Once brewed, gently swirl the Chemex to mix the coffee and ice. This helps balance the flavors and cools the coffee to the perfect drinking temperature.

  • Pour your freshly brewed iced coffee into a glass.

  • Add more ice if desired.

  • Sweeten or flavor with simple syrup, vanilla extract, or a splash of milk.

Tips for the Best Iced Coffee:

  • Use Freshly Ground Beans: Opt for high-quality, medium-coarse ground coffee for the best extraction.

  • Control Ice Quantity: Avoid excessive ice to maintain a balanced flavor and avoid dilution.

  • Experiment with Brewing Ratios: Adjust the coffee-to-water ratio based on your taste preferences for a stronger or milder brew.

  • Try Flash Chilling : Pour the hot coffee directly over a pre-chilled glass of ice for instant cooling without excessive dilution.
