Principles and Characteristics of Cold Drip Coffee and Usage Methods

The Art of Cold Drip Coffee

When coffee grounds are 100% saturated and moistened at low temperature, the extracted coffee delivers a rich, smooth, full-bodied flavor that is truly remarkable. By adjusting the drip speed and using cold water for a slow, extended extraction at 5°C, the coffee's original flavor is naturally brought out.

Advantages of Cold Drip Coffee

Cold drip coffee's advantages include its lack of acidity and its gentle effect on the stomach. That's because this method typically uses dark-roasted beans such as FrontStreet Coffee's Mandheling. Since "light roast is fragrant but acidic, dark roast is bitter but rich," cold drip coffee doesn't come out acidic. Another reason to choose dark-roasted beans is that iced coffee is diluted with ice cubes after brewing, so dark-roasted beans are needed for dripping to ensure enough richness.

Cold drip coffee has a smooth mouthfeel without bitterness precisely because it uses cold water. Other brewing methods mostly use hot water, and water that's too hot can break down certain chemical compounds in coffee and release bitter flavors. Cold drip coffee, by contrast, is made entirely with cold water dripping, ensuring 100% saturation and moistening of the grounds for a smooth, non-acidic, non-bitter extraction.

Usage Instructions

Cold Drip Coffee Pot

1. First, close the water-drip adjustment valve.
2. Pour an appropriate amount of cold drinking water into the water container according to the number of servings. You can also add ice cubes to make iced coffee. The standard water amount for one person is approximately 120cc.
3. Moisten the cloth filter with water, then place it in the coffee grounds cup.
4. Place an appropriate amount of coffee grounds into the grounds cup. The standard amount for one person is approximately 10-12g of extra-fine ground coffee.
5. Finally, place the spherical filter paper in the center of the coffee grounds surface (use size 6 spherical filter paper made specifically for cold drip coffee makers). The spherical filter paper should sit at the point where water from the container drops.
6. Slowly open the water-drip adjustment valve so water drops flow from the container and land on the spherical filter paper. The standard drip speed should be 40-60 drops per minute, adjusted once every 2 hours.
7. The water drops penetrate the spherical filter paper and the coffee grounds, become coffee, pass through the cloth filter, and finally collect in the coffee liquid container. At that point, a delicious, cool, 100%-original-flavor cold drip coffee is complete.

Precautions

1. Be sure to rinse all glassware and the cloth filter with clean water before and after use.
2. Discard the spherical filter paper immediately after use and do not reuse it.
3. The filter cloth on the cloth filter can be reused after cleaning. If you find the filter cloth damaged or giving off an unusual odor before use, stop using it immediately and replace it with new cloth.

Coffee Pot Details

This pot was invented in the Netherlands and is also known as the Dutch-style iced coffee dripper. Its 3-4 layers of glass containers are mounted on a wooden base and displayed in a glass storefront window, creating a spectacular, slightly mysterious atmosphere.

The upper layer of the Dutch-style iced coffee dripper is the water container, with models ranging from 500cc to 3000cc depending on capacity.

Production Process

Materials

Cold drip dripper; dark-roasted coffee grounds, mineral water, ice cubes.

Production Steps

1. Grind the specialty cold drip coffee beans using a grinder setting of 2-3.

Cold drip coffee during extraction

2. Place the filter screen at the bottom of the extraction bottle.
3. Pour the coffee grounds into the extraction bottle and level them evenly.
4. Place the extraction bottle above the collection bottle, then place the drip tray above the extraction bottle.
5. Prepare ice cubes and filtered purified water and pour them into the water reservoir at a 1:1 ratio.
6. Open the control switch to evenly moisten the surface of the coffee grounds.
7. Adjust the flow valve to approximately 40-60 drops per minute for the best results.
8. Production is complete — enjoy.

FrontStreet Coffee Recommendation

Because cold drip works best with dark-roasted, full-bodied beans, FrontStreet's Mandheling lineup is ideal — and Mandheling is FrontStreet Coffee's most popular single origin. FrontStreet's Lintong Mandheling daily beans are medium-dark roasted, intensely aromatic, and full-bodied, with clove and woody notes, low acidity, a spice-and-mint character, and a strong, lingering sweetness that holds up beautifully over ice.

For the highest grade, FrontStreet's PWN Golden Mandheling is the top choice: PWN buys high-quality Mandheling green beans and screens them mechanically and by hand to select plump, defect-free lots (screen 18 or larger with fewer than 3 defective beans per 300g sample, top-grade G1), yielding uniform, large, translucent beans with a low defect rate and, after medium-dark roasting, rich roasted aromas. Its clean yet full-bodied black coffee shows nuts, spices, herbs, licorice, chocolate, and caramel — perfect for cold drip and anyone who dislikes acidity. Drip 10-12g of extra-fine grounds per 120cc of water at roughly 40-60 drops per minute for a smooth, non-acidic, non-bitter cup.
