According to statistics from global market research firm Mintel, US iced coffee sales have risen by 75% over the past 10 years. As industry leaders like Blue Bottle and Stumptown Coffee adopt cold brew methods, and with Starbucks' large-scale promotion, cold brew coffee has become an especially attractive category. Among these, cold drip coffee sales increased by 338.9% from 2010-2015.

Although extraction is slower at low temperatures, flavor-wise, high temperatures more easily cause the tannic acid in coffee to break down into pyrogallic acid, creating acidity and bitterness. Low-temperature extracted coffee is comparatively smoother and more popular in flavor. Common cold brew coffee, iced Americano, and cold drip coffee, while all cold beverages, have very different production processes and flavors.

Cold Drip Coffee (ICE DRIP)

Cold drip uses an ice-water mixture below 5°C, letting ice cubes melt naturally and controlling the speed at which ice water drips onto the coffee grounds through a valve. The ice water slowly dissolves the coffee's flavor as it drips through the grounds, extracting drop by drop, with a complete extraction time of about 2-8 hours. To obtain better flavor, it then requires 12-48 hours of refrigerated fermentation. Each extraction yields very little (typically 30-60 milliliters), and when not diluted with ice, the concentration is extremely high. If the coffee liquid is too concentrated, ice can be added to dilute it to taste. Because of the slow process, cold drip coffee is relatively expensive, but its taste is exceptional.

American barista champion Laila mentioned in an exclusive interview that compared with cold brew coffee, cold drip coffee has more aroma and a more delicate, subtle taste.

Iced Americano (ICE AMERICANO)

Iced Americano is extracted at high temperature from an espresso machine, with the finished coffee liquid poured over ice and then ice water added to taste. It has flavors similar to regular high-temperature extracted coffee; the ice and ice water serve only to cool and dilute.

Japanese-style Cold Coffee

Japanese-style cold coffee is not cold drip coffee, but some say its taste is even better than cold drip, because they believe certain special aromatic molecules need heat to be extracted. The method places a cup with ice under a pour-over filter to cool the extracted pour-over coffee directly. If you want to save time, this is also an option.

The taste of low-temperature extracted coffee varies with the coffee's roast level, water amount, water temperature, drip speed, and grind coarseness. The perfect ratio requires adjustment through time and experience. Low-temperature extracted coffee has a smooth taste, lower acidity, a mellow bitterness, and added complexity after fermentation, but it is also more likely to lose the special flavors that are released only at high temperatures. The choice of bean variety and roast level therefore deserves special consideration too.

How to Make Iced Americano?

There are two methods:

The old method is to immediately pour a shot of espresso over ice, then add ice water. This uses the concept of flavor preservation to maintain the coffee's original taste.

The new method reverses this: first place the espresso in hot water, then add a large amount of ice to cool it rapidly.

Although it looks like only a difference in when the ice is added, the taste is distinctly different.

The subtle impurities in the old method often disappear after sitting for a while, while a hot Americano has almost no impurities.

FrontStreet Coffee's Iced Americano Preparation Recommendations:

Place ice and water in a 1:1 ratio in the cup, then add a double shot of espresso.

FrontStreet Coffee Recommendation

For cold coffee, the beans you choose matter as much as the method. FrontStreet's Strawberry Candy combines a Panama Geisha with a Costa Rican honey-processed coffee, giving rose and orange on one side and grape, raisin, and strawberry-marshmallow sweetness on the other; cold-brewed, it is bright and lively, and left to settle it takes on a fruit-wine character.

If you want florals up front, FrontStreet's naturally processed Huakui absorbs plenty of sweetness from the fruit during drying, and because cold brew amplifies floral and fruit notes while muting woody and roast tones, it pours out magnolia, cream strawberry, dried mango, guava, and black tea.

And for a full, juicy cold brew, FrontStreet's Kenya Little Tomato brings cherry tomato, snow pear, black plum, and dark plum, low in bitterness and generous in acidity, especially refreshing over ice. Cold brew uses more grounds than pour-over, so many drinkers blend it 1:2 with FrontStreet's Costa Rica Tarrazu for a lighter, value-minded cup with clear citrus acidity.
