Coffee + Sparkling Water, Sparkling American Coffee Special Flavor

The combination of coffee and various drinks is nothing new, but this time the combination of coffee and sparkling water (soda water, tonic water) has become a hit on instagram. The photos have been posted by users all over the world. They look refreshing and feel particularly suitable for summer drinking. Let's talk about how to DIY this bubble American special at home in front of the street.

We all know that American coffee, the production method is also very simple, that is, espresso with water, then bubble American is to replace water with bubble water. To make sparkling American coffee, you can use espresso or hand-brewed black coffee. You can refer to the parameters of the front street: espresso 2shot (40g), bubble water 120ml, ice 100g. First prepare a cup with ice cubes, pour into the 120ml bubble water, and finally pour the extracted espresso liquid slowly on the surface. The bubbles are made in American style and stir well with a straw before drinking.

Although the production steps are simple, the bubble American style adds a sense of gas compared to the ordinary American style, and the taste of the coffee will be magnified. If the coffee liquid has a scorched, bitter, astringent negative taste, the bubble American style is likely to become "instant-boiled water", so it is crucial to choose the right coffee beans. Here Qianjie suggests that we use flavor coffee beans, aroma is more prominent, or tend to fruit-conditioned coffee beans, so that the extracted espresso liquid with sparkling water taste more refreshing.

The Italian coffee beans used in the Qianjie store are a "sunflower sunflower mix" baked in Qianjie, which is made up of 30% sun Yega Shirley red cherries and 70% Honduran Shirley. Freshly extracted espresso, the front street will first smell the aroma of coffee, this coffee with full aromas of whisky, vanilla, nuts, cream, made into sparkling American coffee with sweet and sour fruit and a little wine, refreshing and sweet taste.

If you already have those single beans at home for hand brewing, you can also try to extract espresso. As long as you adjust the ratio of coffee powder to water, you can also extract good rich coffee. Qianjie has tried to use Essel's Dorothy, washed Yega Sheffield, Sakuran and Panamanian Rose Summer, all of which are medium-and shallow-roasted and made into American coffee, all of which have a good flavor without acidity and astringency. ) there are some differences between the parameters and the usual extraction. You can also refer to the parameters of Qianjie:

Powder quantity: 20g Grinding degree: 20 sieve pass rate 80% Water temperature: 93 degrees extract Coffee liquid: 80ml the first stage is injected with 40ml water, steam for 2 minutes, then the second stage is injected with 80ml water, wait for the completion of filtration, get 80ml coffee liquid.

As the bubble water contains a large amount of carbon dioxide gas, the coffee oil expands rapidly when poured in, and finally gushes out, and then disintegrates quickly with the unstable state of the oil, thus forming this "pimple" shape. So when we pour espresso, pour it as slowly and gently as possible, so that the coffee retains the rich oil without affecting the visual effect.
