FrontStreet Coffee - Cold Brew Coffee Making Guide

Coffee contains thousands of aromatic compounds, and each extracts at a different efficiency during brewing. Our cold brew blend is specially designed around the characteristics of cold water and low-temperature extraction.

Because cold brew coffee uses cold water for long, low-temperature extraction, the bitter and muddled flavors that come out easily at high temperatures are never drawn out. The result is low acidity, high sweetness, and almost no bitterness — a cup that tastes sweet and refreshing, an excellent summer beverage to beat the heat.

How to Make Cold Brew Coffee

Here is the method:

1. Package the coffee grounds in tea bags.
2. Prepare a glass bottle or other sealable container.
3. Water-to-grounds ratio (this is a variable — adjust freely to your taste. Don't get bogged down in exact numbers; a reference range of 1:4 to 1:10 works well).
4. Water: purified or mineral water is recommended.
5. Place the bags in the bottle, add water, seal well, and refrigerate for about 12 hours. For a stronger flavor you can extend the time by a few hours, but do not exceed 48 hours (the maximum for flavor extraction).
6. Remove the coffee bags and enjoy immediately. Add milk or sugar to your preference.

Beyond daily drinking, it also makes an effortless pitcher for family gatherings. You can even freeze finished cold brew into coffee ice cubes so your iced coffee never waters down as you drink. Coffee should be a relaxing experience — don't get tangled in theories and methods. As long as it's safe and hygienic, make it and drink it however you like. Everything we do is to obtain pleasure.

Knowledge Point

For cold brew bean selection, single-origin beans are recommended — choose based on the flavor profile you enjoy.

FrontStreet Coffee Recommendation

Since cold brew amplifies floral and fruity tones while softening woody and roasted notes, light-to-medium roasts shine brightest. For a floral iced cup, FrontStreet Coffee's natural Ethiopia Huakui is the pick: sun-dried in the fruit, the beans absorb abundant sweet compounds and yield magnolia, cream strawberry, dried mango, guava, and black tea in cold brew. The Strawberry Candy Geisha Blend goes further — Panama Geisha provides delicate rose and orange, while the Costa Rica honey component adds grape, dried blueberry, and strawberry-gummy sweetness; if you let it ferment briefly, it even takes on a fruit-wine character.

Craving full juice texture? The Kenya Cherry Tomato (SL28 and SL34 from Thika, K72 double-washed) shows cherry tomato, pear, black plum, and dark plum at their vivid best over ice, with low bitterness and a long fragrant finish. Cold brew also uses more grounds than pour-over, so value matters: blend 1 part Colombia Sidra with 2 parts Costa Rica Tarrazu to keep the passionfruit-grape-apricot florals and crisp citrus acidity while stretching your budget, or reach for the dependable washed Yirgacheffe Guodingding — sweet berry, layered, and honeyed, and gentle on the wallet.
