What is Yunnan boutique coffee? The difference between Yunnan Fine Coffee and other Coffee beans

We often meet boastful people in coffee-growing areas in Yunnan: "our Yunnan coffee is delicious, our Yunnan coffee has won awards in the world, and our Yunnan coffee is very famous in the world." I asked them if they had had a drink. Where is it good? I can't answer. Many curry farmers mix 15% to 20% green fruit in red fruit. Can this kind of coffee taste good? This kind of coffee is only bitter when roasted. Coffee is a fruit crop. Can it be delicious without ripe green apples and bananas?

There is a saying that Yunnan coffee is called Yunnan small-grain coffee. We all know that there are three varieties of coffee, the Liberika variety is the large-grain species, the Robbda variety is the medium-grained species, and the Arabica variety is the small-grained species. There are more than 100 branches of Arabica varieties. For example, the famous bourbon and tin card species, rose summer seed, S288, SL34, while most coffee producing countries in the world use branches of Arabica varieties suitable for their respective regions to grow. If it is called Yunnan small seed coffee as Yunnan coffee does, then Brazilian coffee should be called Brazilian small seed coffee and Colombian coffee should be called Colombian small seed coffee. Guatemalan coffee is called Guatemalan small seed coffee, is this a little strange, is it a little unscientific?

Won a prize in the world: it was in the 1950s, and the winners were the old varieties bourbon and tin card, which have nothing to do with the Katim species grown on a large scale in Yunnan as raw materials for the instant coffee industry. there are also many unscrupulous businessmen who say everywhere that Yunnan coffee in China is mainly an old variety of bourbon and tin card. Where can I find a mass-produced old variety in Yunnan, China? When promoting our own Yunnan coffee in China, please do not deceive or deceive our poor Chinese consumers, because the price of their consumption of 20 or 30 yuan a cup of coffee is in line with international standards and is often higher than that of developed countries, while the income of our poor consumers in China is several times lower than that of developed countries. So please tell them the truth and don't fool them into saying that Yunnan coffee is an old variety of bourbon and tin card.
