Nitrogen coffee is really hot these days. It tastes silky and mellow, but have you ever wondered why nitrogen coffee tastes so good?

In order to understand the mysteries of nitrogen coffee, we have the honor to invite Ross Nickerson of Raz Function Coffee Labs to introduce some common sense about nitrogen coffee.

● "how on earth is nitrogen coffee made?"

First we need a can of high-pressure nitrogen, and then connect the canister with a tube to a bucket containing cold-extracted coffee. Nitrogen is very low in solubility, and nearly 98% of coffee is water, so we need to press nitrogen through an orifice-filled throttle to mix with coffee, which helps the gas enter the liquid better. Cold extract coffee is mostly used to make nitrogen coffee, but a few coffee shops use instant cooling coffee or hot coffee with rapid cooling.

● "how does this affect the taste of coffee?"

Nitrogen itself will not have much effect on coffee, but it will greatly change the taste of coffee, making it more mellow and silky. In addition, nitrogen helps to maintain the original flavor of coffee and prolong the shelf life of coffee. If there is no nitrogen, the oxidation of oxygen will accelerate the loss of coffee taste, making the coffee tasteless.

● "Why not use carbon dioxide?"

Carbon dioxide can make coffee taste bitter. For example, beer brewed with carbon dioxide will form carbonic acid, making the beer bitter. But beer with its own bitter taste, such as dark beer, must be brewed with nitrogen because carbon dioxide brings extra bitterness and makes the beer taste almost bitter.

● "when did people invent the method of making nitrogen coffee? Was it just invented, or was it invented a long time ago and then picked up again? "

There are many theories about the inventors of nitrogen coffee, but what is certain is that Stumptown Coffee first launched nitrogen coffee products in 2013. Although this method has been used in the beer brewing industry for many years, it is the first time in the coffee industry.

● "can we make nitrogen coffee at home?"

Of course. It's like brewing beer at home. The method is not complicated, but some professional equipment needs to be purchased. Compared with nitrogen coffee, cold-extracted coffee is easier to make and does not require too much effort and money.

● "this method has been used in the brewing industry for many years, right?"

Yes, Guinness invented nitrogen brewing as early as 1959.

● "what are the disadvantages of nitrogen brewing?"

The only drawback is that you need to invest a certain amount of time and money, and not everyone can accept the relatively new idea of nitrogen coffee at the moment.
