Some Facts about Cold Coffee Brewers

When hot summer days hit the globe, a perfectly brewed cold coffee can be the simplest way to cool down and get energized.

Here are some additional facts about cold brew and why it has become so popular in recent years.

A Complex but Perfect Blend

As I said earlier, the perfect taste, smell, and flavor of the coffee mainly rely on how you blend your coffee with other ingredients.

Cold brew is a method of steeping coffee grounds with water at room temperature for at least 12 hours or more. Therefore, filtered coffee results in a yummy flavor. Finally, add sugar, chocolate, milk to the brewed coffee for a perfect blend of taste.

Taste Sweeter than Hot Brew

A cold brew coffee takes much more time than to prepare a hot brew coffee. Cold brew coffee contains 67% less acidity than hot-brewed coffee.

Hot-brewed coffee is easily dissolved in hot water and extracts the caffeine out of the grounds fast. So, you experience a bitter taste. Cold-brew is extracted for a longer time resulting in brighter and sweeter coffee.

Allows Different Flavor

Author Note: You can enjoy different cold coffee varieties with various flavors of fruits, vanilla, and chocolate. Taste light roast and dark roast coffees depending on their brew time as well as caffeine and antioxidants extraction.

Used as Ice cubes

There are different usages of cold brew concentrate. To taste better on an exhausting day, use leftover cold brew to make coffee ice-cream, coffee ice cubes with milk, or a yogurt blend.

How do you keep coffee fresh after opening?

Author Note: Before roasting, the coffee beans have the same carbon dioxide structure as their outer surroundings. But oxidization begins once the beans are exposed to air.
