As soon as summer comes, cold brew coffee has become the most direct communication topic among coffee lovers. Everyone is sharing their experience in making cold brew coffee. Why has cold brew coffee become so popular in the coffee world in recent years? What's the difference between cold brew coffee and regular iced coffee? In this article, let’s talk about this fascinating cold brew coffee.
What is cold brew/cold brew coffee?
Cold brew coffee is a pure black coffee liquid that is soaked in direct contact between normal temperature/ice water and coffee powder at room temperature/low temperature. Due to low-temperature extraction, the flavor release of coffee powder will be much slower than at high temperature, so the soaking time varies with room temperature/refrigerator temperature, and the total extraction time often takes 8-24 hours. Because it does not require any skills or complicated brewing equipment, you can make iced coffee with obvious aroma and high body. Soak it at night and drink it in the morning, which has become a favorite of many working people.
What is the difference between cold brew coffee steeped at room temperature and cold brewed at low temperature?
It is recommended to soak cold brew coffee at warm temperature for no more than 8 hours, while cold brew coffee at low temperature is recommended to be soaked for 12-24 hours.
For cold brew coffee at room temperature, the extraction time will also vary depending on the room temperature. Coffee soaked at room temperature can immediately express a mellow feeling after extraction. The disadvantage is that it is easy to soak out the woody flavor. The advantage of putting it in the refrigerator is that it can soak in a mellow feeling and the woody taste is not easy to appear. The disadvantage is that it takes a really long time...!
What coffee beans are suitable for cold brew coffee?
The liquid displayed by cold brew coffee is not as clear as ice-drip coffee, and a thin layer of oil will float on the surface, making the flavor slightly thicker and more balanced. Front Street recommends using coffee beans with obvious sweetness and sourness/rich aroma to make cold brew coffee. For example, Front Street Sherry coffee beans, Front Street Mozart coffee beans, Front Street Yirgacheffe sun-dried red cherry coffee beans, Front Street Kenyan coffee beans, etc. are all cost-effective single-origin coffee beans suitable for cold brewing.
If you like cold brew with sour and sweet flavors, we recommend the three specialty coffee beans of Front Street Fruit Ding Ding, Front Street Strawberry Candy, and Front Street Oiran. They are not only full of fruity aroma, but also present a delicate sweet and sour taste after low-temperature extraction. If you prefer a balanced taste, we recommend Front Street, Diamond Mountain, Front Street Kaffa Forest, and Front Street Geisha Village Chaka, which have good sour, sweet, bitter, and sweet flavors;
The correct way to make cold brew coffee
Front Street recommends making cold brew coffee at a low temperature in the refrigerator, especially in the south, where the room temperature is quite high in summer. If cold brew coffee is brewed at room temperature, it is difficult to control the soaking time properly.
Cold brew coffee production parameters: 1:10 powder to water ratio, grinding degree is Chinese standard No. 20 sieve (0.85mm hole) sieving rate of 75%, soaked in ice water. When making cold brew coffee, use 50 grams of coffee powder, 400 ml of filtered water and 100 grams of ice. After stirring evenly, seal the bottle and place it in the refrigerator. Extract at low temperature for 8 to 12 hours. It is not recommended to exceed 16 hours (it is easy to over-extract and produce a spoiled taste). After the soaking and extraction is completed, use a filter to filter out the coffee grounds.
The correct way to drink cold brew coffee
Front Street recommends placing the extracted cold-brew coffee in the refrigerator for 2 to 3 hours before drinking, because during the process of leaving it overnight, the coffee liquid will be fully alcoholized with the passage of time and the flavor will be better.
How long does cold brew coffee last?
Cold brew coffee can be sealed and stored in the refrigerator for 5 days after filtering. Although it is said that the flavor of cold brew coffee will be more mellow the longer it is stored, after all, the refrigerator environment is "complex" (especially household refrigerators), and it is difficult to completely avoid the invasion of bacteria. Moreover, every time we check in, it means that air has a chance to enter, so for the sake of everyone's health, Front Street does not recommend leaving it for a week or even a month before drinking it.
