It's hot in summer, so a cool iced coffee is the most enjoyable! But you know, now on the market, there is a kind of "nitrogen coffee" that injects nitrogen directly into the prepared coffee, squeezes it out of the bucket like draft beer, and "brews" the coffee with water dripping from ice cubes. It also attracts a lot of coffee-loving consumers.

The round barrel, with a device similar to squeezing draft beer, pulled down the handle, the caramel-colored liquid slowly flowed out, and a thick layer of bubbles accumulated on the surface, which looked like a glass of fresh beer, but the boss called it "nitrogen coffee".

Pour nitrogen into the coffee for at least 10 hours, not only to maintain the aroma, but also to protect the ice. If you take a closer look, you can see that small bubbles keep coming up. After sitting for a minute or two, you can see the coffee through the light. There are not only no impurities, but also a strong fruit aroma. The unique bubbles on the top give off the smell of milk.

Cold-extracted coffee like this has been very popular with the public over the past five years. From the very beginning, the ice drop coffee slowly extracted the original flavor by adding ice and water, and then let the coffee fully ferment through a spiral snake tube, which took at least eight hours to force out the unique aroma of the coffee.

Compared with one to two kinds of coffee, we all choose high-quality medium and shallow beans, which have long extraction time, strong caffeine and no impurities, so they are suitable for drinking ice, but nitrogen coffee tastes smooth and ice drip coffee has a strong flavor. The boss said that after drinking instant coffee, American coffee with milk and milk foam in the early days, Taiwanese now like to taste the original taste of coffee, but do not want to drink hot coffee. Iced coffee, cold coffee and nitrogen coffee have also become a new choice in hot summer.
