The difference between American Coffee and Fine Coffee the benefits of matching Robusta beans properly

Common American coffee, espresso, lattes and so on use robusta coffee beans (Robusta), also known as commercial beans. The high-quality coffee uses Arabica coffee beans (Arabica). The two are different in variety, gene and composition, so they are different in taste, aroma and flavor in essence.

In fact, the bitterness of robusta coffee beans (Robusta) is fascinating.

Some of our common coffee, such as coffee from beverage stores, convenience stores or coffee beans sold in supermarkets, are actually robusta coffee beans (mostly commercial beans) mixed with Arabica coffee beans (used for both boutique coffee and commercial beans). And brew it with an automatic coffee machine.

The two kinds of coffee beans are fundamentally different because the varieties are different and the number of genes is also different. So the ingredients in the beans are also different, and the coffee baked and brewed is naturally different.

Robusta coffee beans have a unique bitter and astringent taste, and it is really difficult to taste if they are too strong. But if you mix well with Arabica beans and control the proportion of bitterness, sour taste and aroma, robusta coffee beans also have many benefits:

1. Lots of caffeine! The average caffeine of Robusta coffee beans is twice that of Arabica, which is very refreshing!

2. The taste is stable. Because coffee is an agricultural product, it actually varies with different seasons, and Robusta is a relatively stable, disease-resistant and well-growing coffee bean, which is very important for the commercial market.

3. Robusta's bitterness is the same as beer. Proper blending can increase the rich feeling of coffee, which is a very charming trait. Especially with high concentration of caffeine, it is the energy water that wakes up Jason's waiter every morning.

4. Cheaper! The low price of robusta coffee beans is an important thing for the promotion of coffee. But the side effect is that many people think that this is the taste of coffee, but it is not easy to accept boutique coffee full of different flavors.

5, the flavor can be maintained for a long time, because the taste of Robusta coffee beans is more monotonous, for a long time, it will not be too bad. It is very suitable for making take-out drinks, and it won't affect too much after the change of environment, time and temperature. On the contrary, the boutique coffee is too delicate, not only the aroma and taste change with time and temperature, but also not suitable for too long.

6. American coffee mixed with Robusta is easy to make iced coffee, and it is very enjoyable to drink it in summer, because the mellow feeling made by chlorogenic acid is just right with ice cubes. On the contrary, pure Arabica coffee beans are not good.

Why are the flavors of these two kinds of coffee beans so different?

Let's take a look at the comparison of the ingredients of two kinds of coffee beans.

Polysaccharides and sucrose (oligosaccharides) can react with proteins to produce Mena reaction at high temperature, which is the source of many sweet and good tastes. Protein and sucrose can reflect the flavor of caramel, chocolate, nuts and so on.

Arabica has more polysaccharides and sucrose, slightly less protein amino acids, and produces a variety of aromatic and flavor substances after baking. Lipids can turn into floral and fruity substances after baking.

Chlorogenic acid is the most poor, chlorogenic acid will become bitter and astringent. But if it is hydrolyzed with water during the baking process, the problem can be improved. But robusta coffee beans have less moisture than Arabica. So some manufacturers treat Robusta coffee beans with high-temperature steam first.

Conclusion

We usually talk a lot about the floral aroma, acidity, fruity and wine taste of Arabica coffee beans, so let's not say much about this article.

Because of the different ingredients of the two kinds of coffee, they have very different aroma and taste. If you match Robusta's unique bitterness, it is actually a good way to promote coffee. I have to say that convenience stores and beverage stores are good drivers for people to drink coffee together.
