All eyes and tongues of coffee connoisseurs in Indonesia are currently on the cold brew coffee trend. Indeed, sipping a glass of cold coffee on a hot afternoon is much more refreshing than a cup of hot coffee. But is this new trend really any healthier than ordinary coffee, as they say?
Simply put, cold brew is the technique of “brewing” black coffee grounds or best coffee beans for cold brew in cold water (or room temperature water) for approximately 12-24 hours for optimal flavor. You can “brew” the coffee powder of your choice by soaking it in a glass and then letting it sit and filtering it, or using a special coffee brewing tool, such as a french press or cold drip. This cold brewing technique will produce a thick coffee concentrate. This coffee concentrate can be drunk directly as black coffee without further ado, or you can add milk, creamer, sugar, or other sweeteners to mix other coffee creations. For example, cappuccino.
Even though the name contains the word “cold”, cold brew coffee is different from ordinary iced coffee. Making a cup of iced coffee takes less time than “brewing” cold brew coffee. Iced coffee is mixed with coffee powder dissolved in hot water and added with ice cubes afterward to make it cold. Cold brew coffee concentrate is obtained from soaking black coffee grounds in cold or room temperature water. Different techniques produce different flavors. Hot espresso which is used as the basis for iced coffee must be processed more strongly so that the taste and aroma will not fade easily after diluting it with ice. This method of steeping hot water gives black coffee (both hot and iced) a strong, bitter taste and aroma typical of coffee in general. Meanwhile, cold brew takes up to 18-24 hours to produce a concentrate. This process, which is similar to infused water, results in a smoother taste and aroma. This is what causes cold brew coffee to taste sweeter. You can also serve this concentrate cold with ice cubes without having to be afraid of the taste that is too bland because of the runniness. For this reason, cold brew coffee is generally considered the best method for cold brewing.
