The Origin, Brewing Methods, and Varieties of Cold Brew Coffee

●The Toddy cold brew pitcher is the most convenient cold brew coffee tool

The method of extraction by soaking in ice water is another way of making cold brew coffee in Java and other parts of Indonesia, known as traditional cold brew. It requires no technique or mechanism and is the most natural method of extracting coffee.

In 1962, Todd Simpson was on a business trip to Guatemala and ordered coffee at a restaurant. But all that was placed before him was a pot of black extracted liquid and freshly boiled hot water. The server poured the hot water into the black liquid and handed it to him. He could not forget the smooth yet rich coffee flavor he tasted that day, and after returning home, he delved into research. In fact, the coffee-making method he had experienced was commonly used by the Dutch who settled in Java in the 19th century. He named the tool he invented Toddy. At Seattle's Best Coffee and Jean Coffee Beans, the cold brew coffee extract used for iced coffee is also favored by Toddy enthusiasts.

The similarity between cold brew and cold immersion is that both extract coffee liquid by soaking coffee grounds in ice water. Each method has its own characteristics: the cold brew method features spectacular equipment and a pure, natural taste; the cold immersion method uses simple tools and produces a rich, smooth mouthfeel, making it especially suitable for homes and offices.

The principle of cold brew coffee is based on the compatible nature of coffee with water, using melting ice to extract drop by drop. The extracted coffee presents different flavors depending on factors such as the coffee's roast level, water amount, water temperature, drip speed, and coffee grind size.

The structure of a cold brew tower is simple in principle, consisting of an upper chamber, a middle chamber, and a lower chamber. The upper chamber holds ice that melts into water and drips into the middle chamber containing coffee grounds, while the lower chamber collects the extracted cold brew coffee. The production process is highly visually appealing and is one of the coffee extraction methods that best showcases the original flavor of coffee.

After dripping is complete, refrigerate it before drinking for a richer, more delicious taste. The coffee grounds for cold brew coffee are 100% saturated with moisture at low temperature, and the extracted coffee is not only aromatic and rich but also smooth and full-bodied, earning high praise. Its distinctive rich flavor, refreshing and delightful, makes it an excellent choice for a standalone coffee drink in summer.

Drinking: After dripping is complete, refrigerate it before drinking for a richer, more delicious taste.

Principle: Cold brew coffee is mainly extracted drop by drop through condensation and natural permeation water pressure. The flavor of the extracted coffee changes depending on factors such as the coffee's roast level, water amount, water temperature, drip speed, and coffee grind size, resulting in different flavors.

Characteristics: The coffee grounds are 100% saturated with moisture at low temperature, and the extracted coffee has a rich, smooth, and full-bodied taste. By adjusting the drip speed and using cold water for slow dripping at a low temperature of 5°C over a long period, the coffee has a rich flavor and lower caffeine content.
