What Are the Advantages and Disadvantages of Coffee Brewing Methods?

Ice drip, iced coffee and cold brew are three distinct cold coffee methods, and each works differently. Ice drip lets ice water fall through the coffee grounds one drop at a time, so the grounds become fully saturated and the cup turns out smooth, without sharp sourness or astringency. The trade-off is that the drip rate is hard to control; the ideal pace is around 7 drops per interval, which requires patience and attention.

For anyone weighing the advantages and disadvantages of coffee methods at home, ice drip sits at one end of the effort scale. A type of coffee bean such as Mozart, Kenya Small Tomato or PWN Golden Mandheling handles the slow drip well, showing dark berry, clean crisp and sweet aftertaste notes. Coffee-to-water ratio and grind size matter as much as the drip rate, so set both before starting the brew.

In the scorching heat of midsummer, a glass of ice-cold, refreshing coffee is undoubtedly a great way to beat the heat. But did you know that cold brew coffee actually comes in three types: ice drip, iced (iced Americano), and cold brew? Each has its own production logic and flavor profile. This article will help you understand the differences between the three, with a focus on ice drip coffee's drip rate, coffee-to-water ratio, and complete operating process, and will share three beans commonly used at Front Street Coffee stores that are suitable for ice drip—Mozart, Kenya Small Tomato, and PWN Golden Mandheling—each presenting dark berry, clean and crisp, and rich with a sweet aftertaste directions. Whether you want to recreate it at home or are looking for a new summer flavor, this article can provide practical reference.

Summer has arrived, with cicadas chirping outside the window. The scorching heat in Guangzhou is simply torture—if it's not muggy steaming, it's scorching grilling, and occasionally a downpour like boiling water poured over your head. At times like this, having an iced drink in hand instantly switches you from agony to comfort. Recently, at Front Street Coffee (FrontStreet Coffee) stores, quite a few customers ask: Do you have cold brew coffee?

However, cold brew coffee is actually divided into three categories: ice drip coffee, iced coffee, and cold brew coffee. What are the differences between the three? Next, Front Street Coffee (FrontStreet Coffee) will explain them one by one.

Ice Drip Coffee

What is ice drip coffee? Simply put, it's letting ice water drip through a layer of coffee grounds one drop at a time to extract coffee liquid. Legend has it that ice drip coffee originated in the Netherlands, but it also has centuries of tradition in Japan, so it is often called "Kyoto Coffee" or "Japanese-style slow-drip." In South Korea, almost every café has ice drip coffee, and many well-known ice drip equipment brands also come from Japan and South Korea.

The advantage of ice drip coffee is that cold water dripping allows the coffee grounds to be 100% saturated, and the final product is smooth on the palate, neither sharply sour nor astringent. The downside is that the drip rate is not easy to control, with the ideal state usually being 7 drops per 10 seconds.

Coffee dose: 60g Coffee-to-water ratio: 1:10 Grind size: 85% passing through China standard No. 20 sieve Time required: 6–8 hours

1. First, place a circular filter paper at the bottom of the coffee powder cup, wet it with water so it sticks tightly to the cup wall, then pour in 60g of ground coffee (Front Street Coffee (FrontStreet Coffee) uses China standard No. 20 sieve, with 58% passing rate, slightly coarser than pour-over is fine), then gently shake to level the coffee bed. You can also use a tamper with its own weight to lightly press it, making the surface flatter. 2. Cover the surface of the coffee grounds with another sheet of filter paper. The tension of the filter paper allows water to spread evenly over the coffee bed; otherwise, long-term dripping will create a crater in the center of the coffee bed. 3. Use ice water for "pre-infusion," evenly wetting the entire layer of coffee grounds. This step is equivalent to blooming in pour-over and helps improve extraction efficiency and consistency of the final product. 4. Fill the water container with a 1:1 mixture of ice and water, and adjust the valve to about 7 drops per 10 seconds. 5. After production is complete, pour the coffee liquid into a sealed glass bottle and place it in the refrigerator to oxidize overnight, allowing the flavors to meld together, making the mouthfeel smoother and easier to drink.

So, what coffee beans are better for making ice drip coffee? Front Street has several beans commonly used for ice drip, and we'd like to share them with you.

Dark Berry Type : Front Street Costa Rica Canet Estate Musician Series Mozart 60g

Front Street Mozart uses anaerobic honey processing and itself carries a very distinctive raisin aroma. When used to make ice drip coffee, it presents vivid blueberry, black grape, and wine-fermented notes, with a refreshing mouthfeel and a lingering fragrance after drinking.

Clean and Crisp Type : Front Street Kenya Small Tomato 60g

Front Street Kenya Asalia has very lively acidity, overall like a glass of juice. When made into ice drip coffee, it carries the fresh fragrance of cherry tomatoes and grapefruit, with a refreshing, light acidity on the palate, especially suitable for summer.

Rich with Sweet Aftertaste Type : Front Street Indonesia Front Street PWN Golden Mandheling 60g

Few shops use dark roast beans to make ice drip coffee. Those who haven't tried it might think dark roast beans will make ice drip very bitter, but that's not actually the case. Following Front Street's ice drip method, after placing it in the refrigerator for 24 hours and then adding ice cubes, Front Street PWN Golden Mandheling ice drip coffee presents as sweet, with a hint of chocolate bitterness, overall very clear and transparent, and the rich fermented aroma is comforting.

Iced Coffee

Iced coffee is what everyone commonly calls iced Americano. The method for iced Americano is very direct: espresso plus ice water. And the principle of making espresso is: using nearly 9–10 atmospheres of pressure to push near-boiling hot water through finely ground coffee.

Its advantage is that iced Americano is indeed convenient and quick. But there are also quite a few disadvantages: first, you need an espresso machine capable of extracting espresso; second, the taste easily becomes diluted as the ice cubes melt.

Front Street Coffee (FrontStreet Coffee) stores use their own blend, Front Street Sunflower Warm Sun espresso blend coffee beans, which includes 70% Front Street Honduras Sherry and 30% Front Street Yirgacheffe Natural Red Cherry.

20g coffee powder, 27 seconds, extract 40g coffee liquid.

After espresso extraction is complete, add ice cubes and water to the cup, and finally pour the espresso into the ice water, and it's done.

Cold Brew Coffee

Cold brew coffee, that is, Cold Brew Coffee, has a concept similar to cold-brewed tea: a large amount of coffee grounds are directly soaked in water and placed in the refrigerator for long, low-temperature preservation to extract, with the production time taking about 8–12 hours, hence it is also called "ice-brewed coffee."

This soaking method amplifies the coffee's flavor and aroma, reduces acidity, and makes the mouthfeel cleaner and purer. The characteristic of cold brew coffee is that the colder it is, the better it tastes, and adding ice cubes directly doesn't risk diluting the flavor.

The advantage of cold brew coffee is that low-temperature extraction does not easily bring out impurities and bitterness from the coffee beans. The disadvantage is also obvious: the production time is long.

Based on 50g of coffee powder. For grind size, because the water temperature contacting the coffee grounds is lower than ordinary pour-over, choose a setting slightly finer than pour-over, that is, 65% passing through China standard No. 20 sieve. Put the coffee grounds into a glass bottle, then add 400ml of room-temperature water and 100g of hard ice cubes (totaling 500g of ice-water mixture), with a coffee-to-water ratio of 1:10. Then use a stirring rod to mix the coffee grounds and water evenly, seal it, and place it in the refrigerator to chill.

After placing it in the refrigerator for 12–24 hours, filter out the coffee grounds with filter paper to obtain clean coffee liquid, then put it into a clean sealed bottle and refrigerate for about 4 hours before drinking.

Although low-temperature extraction does not easily bring out impurities and bitterness from coffee beans, after all, the extraction time is longer and it is an immersion method. To avoid the finished coffee liquid being too strong, it is recommended to adjust the grind size coarser.

So what coffee beans are suitable for making cold brew coffee? Of course there are. Front Street Coffee (FrontStreet Coffee) here recommends Front Street Strawberry Candy coffee beans. Its cold brew coffee has a rich floral and berry aroma, abundant creaminess, and pleasant fruity sweet-and-sour notes.
