The most controversial cup test, Kopi Luwak and Rosa Coffee
Follow the caf é (Wechat official account vdailycom) and found that Beautiful Cafe opened a small shop of its own.
The coffee roaster / retailer The Temple Coffee team from Sacramento in the central United States specially organized a cup test event-Kopi luwak (civet coffee) VS. Rosa Coffee tests people's perceptions of the two coffees, both of which are the most famous on the market.
The following is the activity process described by Temple Coffee trainer Cole Cuchna

One of our coffee dealers went to Bali recently and brought us a bag of kopi luwak,a.k.a civet coffeee, commonly known as Kopi Luwak.
The attractiveness of this extremely expensive coffee has nothing to do with the altitude of the climate in which it grows, and has nothing to do with the genes of its coffee tree species, but from its special treatment. The civet eats coffee fruit, which is fermented in the cat's digestive system and then excreted in its feces.
In the coffee industry, civet coffee is a kind of market hype which is the basic consensus. It has no cup test quality characteristics, has nothing to do with the growing environment of coffee, can not talk about treatment technology and tradition, and does not need the requirements of coffee tree species. But it has a mysterious color that attracts a lot of people. Because civet coffee is not only a kind of coffee, it is a story, whether good or bad, right or wrong, it is a topic that people talk about.

Ironically, many coffee connoisseurs think highly of this marketing method: good coffee must be expensive, and good coffee must be the coffee that people often talk about. Of course, we can also use this concept to discuss rose summer coffee, rose summer coffee as a rare coffee variety has the quality recognized by experts, it also has a sense of mystery and legendary.
At the same time, there are few opportunities to compare and test the two coffees, and the best way is to let the participants evaluate it. Is Rose Summer really that good? Is Kopi Luwak really that bad? How do the two compare with typical boutique coffee? To answer these questions, we arranged a set of tests for coffee including: Kenya Gichuka, Kopi Luwak (Kopi Luwak), Costa Rican Honey processing, Guatemala Rose Summer, Panama Emerald Manor Rose Summer.
More than 20 people participated in the activity, and the test was, of course, a blind test. The process is simple: try each kind of coffee, take notes, choose your favorite coffee, and we even complain that everyone has a Kopi Luwak, whether you like it or not.
During the event, I knew the exact location of Kopi Luwak, and I kept an eye on the faces of people when they tried it.
After the test, vote by a show of hands to find out everyone's favorite coffee.
When we pointed to Kopi Luwak to ask members to vote, no one raised their hands, zero.
When we pointed to Rose Summer, half of them raised their hands.
It seems that the showdown between Kopi Luwak and Rosa Coffee is one-sided.
I ask you to describe Kopi Luwak.
It smells stale and musty.
"weird".
"like BBQ sauce".
"Dinosaur droppings in the bathtub" (Washington Post food writer Tim Carman's comment).
Obviously, cat shit coffee alone is not worth its high price in terms of quality and taste.

The taste of emerald rosy summer is active in taste, vitality, flower, fruit and so on. My humble opinion: drinking good coffee like Rosa is worth every penny. Our conclusion is that the quality of coffee represents everything, and it can create a myth or break a myth.
