A brief introduction to the production area of hand-made Colombian coffee by describing the taste characteristics and flavor
Columbia Pavilion official Mercio Prada told Xinhua that the venue held a two-week coffee exhibition for visitors to taste Colombian coffee and introduce and promote Colombian coffee and coffee culture to tourists from China and around the world.
Jamie Valencia, a history professor who participated in the construction of the Columbia Pavilion, said that as tourism between Colombia and China heats up, cultural exchanges between the two countries will become more frequent. He said: "although Chinese people like to drink tea, it is not impossible to gradually change some of their food culture. Now there have been some changes."
Students who have done classic experiments in organic chemistry know that caffeine sublimation must first remove water, because water will affect caffeine sublimation. As for coffee beans, can deep baking remove all the water? Obviously not, this in the limited time of baking, will further affect caffeine sublimation.
Caffeine sublimation in the roaster is somewhat similar to the solvent-free direct sublimation method in the laboratory, but with the addition of a catalyst in the laboratory, can the rate of two hours be 50%? If you don't add a catalyst, how much can an extra few minutes of deep baking do? It is much easier to sublimate the broken tea used in the laboratory.
Choosing coffee beans that suit your taste is an important criterion to determine whether your cup of hand-brewed coffee tastes good or not. Many people say that it is too light, astringent and miscellaneous, and the first thing we consider is coffee beans. If the roasting degree of coffee beans is too shallow, it is easy to appear astringent taste, because there will be raw. So I suggest beginners to choose medium-deep baked beans, wait for their own skills, or really want to drink light-baked beans, and then try to buy shallow-baked beans. Therefore, stop worrying about whether it is your own way of making mistakes, but to buy beans from the beginning should be suitable for you, coffee is very knowledgeable, but also a very magical plant, do not overnight, challenge low-controllable beans.
