Cold brew coffee was originally invented to make coffee last longer. Extracting with cold water does not draw out large amounts of coffee oils the way hot water does, so if stored properly in the refrigerator, it can keep for a month without any problem. After three days of aging, the flavor becomes even mellower. However, cold water extraction takes a very long time—common methods can even require dripping for more than 24 hours—and the caffeine concentration is relatively high. In fact, when making it at home, using room-temperature water instead of ice water works just as well and can shorten the time. This article will explain in detail the complete cold brew process, including sterilizing equipment, choosing grind size, the coffee-to-water ratio, controlling drip speed, and how to prevent refrigerator odors from affecting the coffee's flavor, helping you make a rich and aromatic cup of cold brew coffee.

Dirty has always been a popular product in coffee shops thanks to its high aesthetic appeal and the unique experience of hot and cold colliding. When making a Dirty, using a chilled glass can extend the layering effect between the espresso and the milk, but should you use a refrigerated glass or a frozen glass?

The rise in popularity of -86°C Dirty has brought frozen glasses into the spotlight once again. This article explains in detail the differences between refrigerated and frozen chilled glasses, the points to note when making a Dirty with a frozen glass, and why purified milk is the best partner for a frozen glass, helping you fully understand the intricacies behind this dirty coffee.
