Cold Brew, Iced Drip, Iced Americano, Iced Japanese Coffee: Do You Really Understand the Difference?

The four most common types of iced coffee we encounter are iced Americano, iced pour-over, cold brew, and iced drip coffee. Some friends may not be familiar with all four, so FrontStreet Coffee will explain their characteristics and differences from several angles.

Extraction Methods

In terms of extraction methods, both iced Americano and iced pour-over are made by brewing hot coffee first and then rapidly cooling it with ice; cold brew and iced drip coffee are extracted with cold water throughout the entire process.

Iced Americano is made by extracting espresso with an espresso machine, then adding appropriate amounts of ice water to cool and dilute it. Iced Americano preparation method: grind 20g of FrontStreet Coffee's Sunflower Warm Sunshine coffee beans, extract 40g of coffee liquid using a 1:2 coffee-to-liquid ratio over 25-33 seconds, prepare a 300ml glass cup with 90g of ice cubes and 180g of drinking water, pour in the extracted espresso, and stir before drinking.

The iced Americano made from FrontStreet Coffee's Warm Sunshine beans immediately reveals rich layers upon tasting, with subtle vanilla and berry flavors accompanied by creamy smoothness, making it refreshingly mellow and thoroughly satisfying for summer consumption.

Iced Pour-over Coffee

Iced pour-over is made by first brewing hot coffee using the pour-over method (slightly stronger than a normal serving), then adding ice cubes to cool and dilute it. The detailed method is as follows. Here FrontStreet Coffee uses the medium-light roasted FrontStreet Coffee's Fruit Ding Ding as an example, adopting high-concentration, high-extraction iced brewing parameters:

Coffee dose: 15 grams
10 times hot water: 150 grams
5 times ice amount: 75 grams
Water temperature: 92°C
Grind size: 83% pass-through rate on #20 sieve (EK43s setting 9, C40 setting 22)
Dripper: Hario V60
Technique: Three-stage pouring

First, place 75g of ice cubes in the server, then pour 15g of ground coffee into the filter cup and gently level it. For the first stage, pour 30g of hot water from the center outward in small circles at a 3ml/s flow rate and let it bloom for 30 seconds; after 30 seconds, pour the second stage of 60g water using the same technique, being careful not to raise the liquid level too high to avoid under-extraction; when the coffee liquid is about to run dry, pour the remaining 60g of hot water at a 3ml/s flow rate, ensuring the extraction time falls within 1 minute 50 seconds to 2 minutes.

Cold Brew Coffee

Cold brew coffee is made by steeping coffee grounds in cold water for a relatively long time, then filtering out the grounds before drinking. The preparation method is as follows.

Using FrontStreet Coffee's Strawberry Sugar as an example, when making cold brew we use a 1L cold brew pot, prepare 60g of Strawberry Sugar coffee beans, and grind them to the size of fine sugar (80% pass-through rate on the China #20 standard sieve), with the specific coarseness as shown. Next, pour the ground coffee into the pot, add 600g of drinking water at a 1:10 coffee-to-water ratio, stir thoroughly with a long spoon, seal it, and refrigerate for 8-12 hours. Once steeping is complete, take out the cold brew pot, stir thoroughly again with a spoon, then pour it through filter paper to separate the grounds until all the coffee liquid is filtered cleanly, and the cold brew is ready.

Iced Drip Coffee

Iced drip coffee uses ice water in the form of drops, dripping one by one into the coffee grounds layer to extract the coffee liquid. Production time is generally quite long, and the dripped coffee liquid needs to be refrigerated before drinking. The specific method is as follows:

Similar to the flow rate of pour-over, but iced drip's flow rate is calculated in drops per second. The slower the flow rate, the longer the total time required, and the easier it is to encounter over-extraction. FrontStreet Coffee typically uses 7 drops every 10 seconds for extraction, and individuals can adjust the flow rate according to their preferences. The coffee-to-liquid ratio is 1:10. Since FrontStreet Coffee serves iced drip coffee diluted with ice cubes, we use a higher concentration. If making it at home, you can use 1:12-1:14 for extraction. FrontStreet Coffee uses 60g of coffee beans ground into powder, places a circular filter paper at the bottom of the coffee chamber, pours in the coffee grounds, and finally places another filter paper on top, then moistens the grounds with water, which saves dripping time while avoiding uneven extraction. Fill the upper chamber with an ice-water mixture, meaning ice and water at a 1:1 ratio, extracting a total of 600g of coffee liquid.

Production Time

In terms of production time, iced Americano and iced pour-over are relatively fast, taking only a few minutes to complete; cold brew and iced drip coffee have longer production times, generally with cold brew taking about 12 hours and iced drip taking 6-8 hours.

Ease of Preparation

For home preparation, both iced pour-over and cold brew are relatively simple to make. Cold brew has low equipment requirements; a sealed bottle will suffice. The equipment for iced pour-over is also quite affordable, and generally if you already brew coffee at home you will have pour-over equipment.

Iced Americano requires an espresso machine, and the equipment needed for iced drip coffee is somewhat more expensive.

Flavor and Mouthfeel Differences

FrontStreet Coffee would like to point out first: whether coffee is acidic or bitter, whether it shows floral and fruity flavors or nutty chocolate flavors, mainly depends on which flavor of coffee beans are used. The influence of the extraction method is not as significant. Different preparation methods produce iced coffees with different stylistic expressions, and these expressions are comparative differences. Regardless of the method, the resulting flavor cannot escape the basic flavor profile of the coffee beans.

The flavor characteristics of iced Americano are generally light, refreshing in mouthfeel, and typically express the most basic flavors of the coffee beans. The liquid appears relatively cloudy.

The characteristics of iced pour-over are a clean and refreshing mouthfeel, easily highlighting the main flavors of the coffee beans, with a clear and bright liquid appearance.

The characteristics of cold brew are less bitterness, balanced flavors, and high sweetness. The mouthfeel is heavier than iced pour-over, and the liquid clarity is slightly lower than iced pour-over.

The characteristics of iced drip coffee are rich fermented flavors, such as wine-like notes. With the same beans, iced drip has higher bitterness than the other three types of iced coffee, and also a superior mouthfeel.

FrontStreet Coffee Recommendation

Because cold extraction amplifies floral and fruity notes while muting roast and woody tones, FrontStreet Coffee suggests starting with light to medium-light beans. FrontStreet Huakui is a naturally processed Ethiopian bean: the long contact with fruit pulp builds up sweet aromatic compounds, and in cold brew it shows magnolia, creamy strawberry, dried mango, guava and black tea. FrontStreet Strawberry Sugar, a Geisha blend built on Panama Geisha and Costa Rican honey-processed coffee, gives rose and orange from one side and grape, dried blueberry and strawberry fudge from the other, and it turns almost wine-like if you let it rest and ferment a little. For a full juice-bomb cold brew, FrontStreet Kenya Cherry Tomato brings cherry tomato, snow pear, black plum and smoked plum, with low bitterness and a bright, saturated acidity that stays refreshing over ice. FrontStreet Yirgacheffe Gedingding is the easy everyday option, showing sweet berries, layered honey and a clean finish.

For cold brew, FrontStreet Coffee recommends grinding to fine-sugar size at about 80% pass rate on a China #20 sieve, then steeping at a 1:10 coffee-to-water ratio in the refrigerator for 8-12 hours before filtering. If you want to stretch a pricier bean, blend FrontStreet Colombia Sidra with FrontStreet Costa Rica Tarrazu at 1:2 to keep the passion fruit, grape and apricot sweetness of the Sidra while adding the crisp citrus acidity of the Tarrazu at a friendlier cost.
