Hougu Classic Black Coffee is a cost-effective instant black coffee product under Hougu Coffee. The following is a detailed introduction:
Raw material quality
We use 100% Arabica coffee beans, all from the western Yunnan Plateau at 25 ° N. Here, the temperature difference between day and night is large, and the rainfall is abundant, giving the coffee beans a balanced sour and bitter taste and rich oil content.
Craftsmanship
Using freeze-drying technology and Danish freeze-drying equipment, coffee aroma substances are locked in at -40 ℃ to preserve the original flavor of coffee to the greatest extent possible. It can achieve instant dissolution in 3 seconds and is suitable for various drinking scenarios with cold and hot dual flushing.
Taste characteristics
The entrance is mellow, with moderate bitterness and a subtle caramel sweetness and slight fruit acid. The overall balance is excellent, and after brewing, you can observe the oil hanging in the cup, which is relatively rare in instant coffee.
nutrients
Without adding vegetable fat powder, sucrose, and trans fatty acids, a single cup contains only 6.38 calories, with a protein content of 22g, fat content of 1.8g, and energy of 1335KJ per 100g, making it healthy and low-fat.
