Technical Guide: AeroPress Iced Coffee - Bean Selection Tips and Making Tutorial

Iced coffee is an essential summer beverage, and many friends ask FrontStreet Coffee how to make it well. Here, FrontStreet Coffee will share some thoughts on this topic. First, making iced coffee involves many factors: fresh beans, appropriate grind size, precise extraction time, and more. FrontStreet Coffee has chosen a FrontStreet Coffee washed Yirgacheffe to demonstrate using an AeroPress. The reason for choosing FrontStreet Coffee's washed Yirgacheffe is its delicate floral aroma, clean taste, and bright acidity. When made into iced coffee with AeroPress, the acidity of FrontStreet Coffee's Yirgacheffe becomes more refined while preserving its original floral and fruit notes, adding a richer juiciness—making it perfectly suitable.

What is an AeroPress?

The AeroPress construction can be simply broken down into three main parts: the chamber, the filter cap, and the plunger. It combines the immersion extraction method of a French press, the paper filtration of pour-over coffee, and the pressurized extraction of an espresso machine. Its working principle involves mixing coffee grounds with hot water, stirring, then using the plunger to force air through the filter cap to extract coffee with clean flavors.

Bean Selection:
Balance of sweet and sour: Honey processed, such as FrontStreet Coffee's Costa Rica Musician Series
High sweetness: Natural processed, such as FrontStreet Coffee's Natural Flower Queen / High body: FrontStreet Coffee's Lin Dong Mandheling, FrontStreet Coffee's Gold Mandheling / Bright acidity: Washed, such as FrontStreet Coffee's Kenya Small Tomato

Brewing Guide

Brewing Approach: Use AeroPress to extract high-concentration, high-extraction coffee concentrate, then add hard ice cubes to cool and dilute it to your preferred taste. Therefore, choose a finer grind size, higher water temperature, and a different coffee-to-water ratio.

For coffee beans, we selected FrontStreet Coffee's Yirgacheffe Washed Kochere from the FrontStreet Coffee bean menu. Detailed information is as follows:

Region: Yirgacheffe Kochere
Altitude: 1800-2200m
Variety: Local heirloom varieties
Processing: Washed
Flavor Notes: Lemon, Black Tea, Orange Blossom

Brewing Parameters

Coffee Dose: 20g
Coffee-to-Water Ratio: 1:9
Grind: Espresso grind (flour-like)
Water Temperature: 92°C
Time: 1 minute 30 seconds

Brewing Process

1. Take out the filter cap, attach a dedicated AeroPress paper filter, and wet it with hot water to make the filter adhere tightly to the filter cap.

2. Place the AeroPress upside down, pour 20g of ground coffee into the chamber, then pour 180g of 92°C hot water and start timing.

3. After pouring the water, stir gently with the stirring stick for 50 seconds. Cover with the filter cap and press upward to remove excess air.

4. Flip the AeroPress so the filter paper and cap face down, coffee grounds face up, and press downward to extract. The extraction should take about 30 seconds. At this point, we have approximately 150ml of high-concentration coffee concentrate. Total extraction time is 1 minute 30 seconds.

5. Pour the coffee concentrate over 120g of hard ice cubes to cool and dilute the coffee. You can adjust the amount of ice according to your taste preference.

6. Shake gently to ensure consistent concentration and temperature throughout. Then it's ready to enjoy! After dilution with ice, you can experience the freshness of ice lemon, citrus acidity, a clean taste, and a sweet black tea sensation in the middle section—very refreshing and comfortable.
