Bottled Nestle coffee tastes a little sour, and it's true that it hasn't expired. What happened?

coffee can be divided into Arabica and Robusta. Arabica is very demanding on the growing environment, so it is regarded as good coffee and expensive.

Arabica's characteristics: fragrant smell, soft coffee taste and sour aftertaste

Robusta's characteristics: dull color, astringent coffee taste and bitter aftertaste

At present, the bottled Nestle coffee (alcoholic products) adopts patented low-temperature extraction technology, and at the same time, a relatively large number of high-quality Arabica coffees are screened, so the taste is sour. However, if you try the pure blue mountain coffee, you will find it more sour.

the sour aftertaste is a sign of good coffee. But if you are not used to this taste, you can choose to add a partner or sugar to solve it. In addition, it is recommended that you make coffee with water of about 85-9 degrees, which can also alleviate the aftertaste of some acids.
