●, what is nitrogen coffee?
Nitrogen Coffee-Nitro Coffee, as the name suggests, is the addition of liquid nitrogen to the coffee.
In recent years, with the progress of science and technology, liquid nitrogen is easy to be made and preserved, and many beers have begun to switch to nitrogen. The bubbles produced by nitrogen are more detailed than those produced by carbon dioxide and are more likely to have a rich taste.
Since nitrogen can be combined with beer, it can also be combined with coffee. Under high pressure, nitrogen dissolves in water, and when nitrogen is poured out of the pressure cylinder, the pressure decreases, and nitrogen expands from the dissolved state into tiny bubbles. These small bubbles are called Sweet foam in molecular cuisine. The process of breaking on the tongue will make the brain feel "sweet".
●, who invented nitrogen coffee?
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.
In 2015, due to the soaring market demand, Stumptown decided to launch canned nitrogen brewing coffee products. Also last year, Caribou Coffee launched a barrel of nitrogen brewed coffee in stores; by Feb. 25 this year, the product was launched in more than 600 Caribou Coffee stores.
In July, Starbucks will become the third and most influential multinational coffee chain to launch nitrogen brewing coffee products.
How does ● make nitrogen coffee?
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.
Will ● nitrogen 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.
How does ● make nitrogen coffee?
Cold extraction is the main way of nitrogen coffee. Coffee powder is extracted at low temperature for a long time to dissolve the oil and aromatic substances with flavor, which avoids the bad flavor produced by high temperature reaction. Ice droplets are a good choice.
Put the cold extracted coffee into the 4-degree coffee machine, adjust the machine, inject nitrogen, and fully mix the coffee with nitrogen to produce.
Of course, you just need to know about homemade nitrogen coffee, and you don't have to really work hard to do it. Because making your own cup of nitrogen coffee requires a lot of time and money, for example, to buy some expensive professional equipment, the cost of curiosity is a bit high. Or go to the coffee shop and order a cup of nitrogen coffee, which is more cost-effective.
