It's just the difference between acid and bitterness. The bigger the number, the more bitter it is. On the contrary, the acidity will decrease.

This means that 1 17 is more bitter than 1 14, and its acidity will be lower.

This difference is actually very small, and most people can't tell it apart. Just choose 1 17 if you like bitterness, and 1 14 if you don't like bitterness. And because coffee partners are usually used when drinking coffee, Chinese coffee is generally not bitter and sour, only sweet, so don't worry so much.

The difference in taste is that 1 14 and 1 17 are soft and 1 17 is bitter.

The taste of 1 14 is between bitter and sour, representing neutrality. So you can choose according to your personal requirements for acid and bitterness. I usually buy two bottles at the same time, so I want to drink sour 1 14, bitter 1 17, and half if I want to neutralize.

1 17 is black coffee with a very high aroma. Because it uses deep roasted coffee beans, this one will have a slight smoky feeling and tongue-pressing feeling. I like black coffee & friends who are losing weight, please plant grass for yourself! Compared with 1 17, the bitterness of 1 14 will be weaker.

Taste:

Taking carefully cultivated and fixed-point planted coffee beans as raw materials is the two major insistence of Japanese UCC coffee. The coffee bean produced by UCC coffee is one of its main symbols, such as UCC Blue Mountain 1 Coffee Bean, UCC European Royal Charcoal Coffee Bean, UCC Selected Coffee Bean, UCC Charcoal Coffee Bean and so on. And the coffee powder it sells is not inferior.

Because there are many varieties, coffee powder has its own digital code, such as 1 13: it tastes soft and easy to dissolve; 1 14: soft taste; 1 17: rich in flavor; 1 18: sweet and sour. The larger the number, the deeper the bitterness and the weaker the acidity. Therefore, the numerical code difference of UCC coffee is more precisely the difference of coffee taste.
