Traditional Cold Brew Method

Traditional Cold Brew Method

The traditional cold brew method is widely regarded as one of the most popular techniques for achieving a superior flavor in cold brew coffee. Brewing temperature and coffee grind size are two key factors that contribute to the success of this method.

Regarding brewing temperature, it is important to note that cold brew coffee is brewed using cold or room temperature water rather than hot water. This lower temperature allows for a slower extraction process, resulting in a smoother and less acidic flavor profile.

The ideal brewing temperature for cold brew coffee is between 36 to 40 degrees Fahrenheit (2 to 4 degrees Celsius), as this range promotes optimal flavor extraction without any unwanted bitterness.

In addition to brewing temperature, the coffee grind size plays a crucial role in achieving a superior flavor in traditional cold brew. For cold brew, a coarser grind size is recommended. This is because a coarser grind allows for a slower extraction process, resulting in a smoother and less bitter cup of coffee.

A medium-coarse grind size, similar to that of coarse sea salt, is typically preferred for traditional cold brew.
