The must-try summer coffee

 

Summer is around the corner. A cup of hot coffee is less tempting for most people. However, as coffee lovers, we still need our caffeine fix as usual.

A friend from Chongqing (Hotpot city) asked me about cold brew coffee because she would like to introduce a new beverage in her recently opened hotpot restaurant.

My first reaction was: This is cool! It’s a bold and chic combination, and yet its flavor is mysterious. 

My friend has inspired me to understand what cold brew is and how it is made.




What is cold brew?

     

Many people know about cold brew from Starbucks.

We usually order a pour-over or siphon single-origin coffee as hot brewed, i.e., using hot water to extract coffee and also then drinking it hot.

Cold brew is different from ordinary iced coffee, which was brewed with hot water and then added into ice cubes.

Cold brew is to extract coffee using room temperature water or even ice water.

Due to low temperature, substances with larger molecules, such as tannic acid, are not easily extracted. Therefore, cold brew coffee is smooth, less bitterness, and has zero astringency.

Cold beverages are instantly refreshing durning the hot summer. Cold brew not only energizes our brain but is also convenient. It can keep the original flavors of the hot coffee we love, depending on coffee varieties and roasting level, but now with the new trend of home-made cold brew. 



 Market Trend

   

In fact, cold brew has been popular in the U.S. for quite a while and is still increasingly trendy.

Data show that as new products continue to surprise us, sales of cold brew in the United States in 2017 are 28% higher than those of regular iced coffee, and by 2018 it is 40% higher. Meanwhile, cold brew is more popular in Canada than in the United States. To put it into perspective, in 2018, Canada sold 85% more cold brew than regular coffee!

The cold brew trend is continuing to get hotter and hotter.


Nitrogen cold brew coffee is amazingly delicious!

By adding nitrogen into the cold brew coffee, a unique silky and dense texture will be created. While drinking, countless small bubbles make the mouth feel thicker and smooth.

In addition, nitrogen helps keep coffee liquids fresh.

According to Matthew Hartings, a professor of food chemistry at a university in the U.S., coffee is highly oxidizable.  Similar to rusting of iron, the longer it’s exposed to oxygen, the more acid and bitterness it produces. Therefore, adding nitrogen can slow down the degradation rate of coffee flavor substances.

Through adding nitrogen, the oxygen in the coffee liquid is forced out, which makes the flavor essences in coffee more stable.

In the hot summer of almost 40 degrees, who can refuse a glass of smooth, delicious and flavorful nitrogen cold brew?



Making and storing is easy

   

Most of cold brew can be produced in bulk. Since it's extracted in a lower temperature, cold brew beverages can be stored for a longer period of time, which is convenient for (chain) coffee shops of higher volume.
