How to make espresso crema more?
One refutation for not using Robusta in condensed combinations is that "Robusta can bring better crema to concentration." This is true, because Robusta contains less oil than Arabica. On average, Robusta contains only half as much flavor and aromatic oil as Arabica, which means less oil can be extracted, and they are less destructive to bubbles. Adding Luodou will correspondingly reduce the total amount of oil that can be extracted, and the result is obvious, and you will get more crema.
Food technologists will tell you that a low oil content will make the concentrated body feel thicker at first, but the low oil content means that the concentrated taste containing Luoda is not as durable as that of pure Arabica and less full. So if this argument is to work, you need to control the use of Luodou at 5% to 10%, so that you can increase the amount of crema without losing too much quality. Some articles focus on the effects of Robusta's special sugars on crema, and it is hoped that the research results in this area will be disclosed and updated.
All of this does not solve all the questions about crema. When making coffee, you will encounter some unusual concentrations, which produce a very unique crema because of its special chemical composition. With regard to this situation, it is obvious that the coffee grown ecologically in the southern state of Minas, Brazil, and the Camocim estate uses Dry pulp (that is, the coffee fruit retains more pulp to dry) to deal with this yellow bourbon. When tested in a cup, this bean has a very strange sweet taste, and when used to make espresso-even if it has been grown for nine days, it still produces extremely rich and thick crema.
After placing the concentrate for a long time, there will still be crema with a texture similar to that of dried milk foam. This is not the only coffee that produces "special" crema. Coffee that is usually treated in a special way, such as Malabar monsoon beans, produces a very special texture of crema, but the crema tastes dry and bitter.
To sum up, even within Arabica, there are many differences in crema among different varieties, mainly due to the form of carbon dioxide stored in different coffees, the content of oils and lipids in different coffees, and how these oils and lipids are extracted. The controversy about crema between Arabica and Robusta is actually very limited. In the case of Arabica coffee alone, the discussion of crema can even be extended to micro-genera.

If you are using filter paper, you need to wet the filter with hot water before making coffee. This can remove the odor of the filter paper itself and ensure the integrity and adequacy of coffee extraction. Now you can officially start making coffee. The water temperature boils the water to a temperature of 212 ℉. Stop heating and lower the water temperature to 200-208 ℉. Too high water temperature will cause coffee.

What is crema? Why did crema disappear? A series of complex chemical changes occur during coffee roasting to produce large amounts of carbon dioxide. Most of the carbon dioxide will be released naturally during the storage of ripe coffee beans, but more carbon dioxide will remain in the cell wall. The pump pressure correlation of 9 bar is the insoluble oil in emulsified coffee. actually
