Cold brew coffee is becoming increasingly popular compared to the traditional method of brewing coffee with hot water. The hot water method requires a coffee filter and careful pressing of the coffee grounds into the filter when pouring water. Watching the hot coffee drip down and the aroma that rises from it is quite fascinating.
However, these days the cold brew method is gaining popularity. In particular, cold brew coffee creates a different flavor and function compared to hot brewed coffee.
When using hot water, the coffee produces a strong aroma but often has a slightly acidic taste. Also, since the coffee has been brewed using hot water, it doesn’t stay fresh for long and needs to be consumed immediately. If stored, it quickly becomes sour. On the other hand, cold brew coffee extracts gradually from the coffee grounds, resulting in a smoother and milder aroma. The water does not become acidic, making it easier to drink compared to hot brewed coffee. Additionally, you can adjust the flavor of cold brew coffee to your preference based on the brewing time. While hot brewed coffee offers only one flavor, cold brew coffee allows you to experience various layers of aroma with different intensities in each batch. Instead of watching the coffee drip into the filter, you can check the brewing container in the refrigerator and smell, taste it to determine the desired brewing time for next time.
Cold brew coffee also reduces bitterness and provides a more refreshing flavor. Give it a try, and you will notice the difference between hot brewed coffee and cold brew coffee.
When cold brewing, bitterness is reduced.
Cold Brew Coffee Preparation
First, put the coffee grounds in a coffee filter bag. Place the coffee filter bag in a container of boiling water to allow it to cool down, and then place it in the refrigerator for brewing. The amount of coffee to be brewed depends on the intensity of flavor you desire and the type of coffee you purchased. The coffee will slowly infuse into the water, gradually darkening in color and increasing in aroma. You can check it after a few hours to taste and smell it to determine your preferred flavor. Many people prefer brewing for about 16 hours for a stronger flavor. However, some enjoy brewing for 10 hours or even 5 hours… The aroma and color of the coffee change over time. If it’s your first time brewing, observe the aroma you prefer after refrigerating for a certain number of hours, and use the same brewing time for subsequent batches.
It is important to seal the container tightly with the coffee filter bag inside to avoid absorbing odors from other foods in the refrigerator. When you open the container, you will notice the gradual change in aroma over the brewing time.
After brewing, you can store the iced coffee in the refrigerator for a week. Each time you want to drink it, simply pour it over ice and add sugar or milk as desired.
The most notable feature of cold brew coffee is its ability to maintain a refreshing aroma compared to hot brewed coffee. The longer the brewing time, the stronger the coffee flavor becomes. If the brewing time is too short, the coffee will be weak, and not all of the coffee’s components will be fully extracted.
Cold brew coffee is suitable for those who enjoy drinking iced coffee. If you prefer hot coffee, this method may not be as suitable. However, you can still heat up the cold brew coffee, but it is recommended to heat it in a microwave and avoid adding boiling water.
