Espresso versus coffee: more intense aroma and less acid
What tastes better and what is healthier? This is a question many people ask about espresso and conventional filter coffee. Does coffee draw water from the body? Is coffee diuretic? A few answers will surprise you.
After a good meal, a cup of espresso tastes particularly good. The earthy and chocolatey stimulant has its home in the Italian metropolis of Milan and was initially only prepared in bars and upon direct request. Therefore, the word "espresso" also means a "dish prepared for the guest".
Compared to normal filter coffee, espresso has a stronger taste and a more intense aroma. This is not due to the bean, because the Arabica and Robusta varieties are used for both coffee and espresso. The roasting makes the difference: the beans are roasted for 15 to 18 minutes for espresso, and only 10 to 15 minutes for coffee. This makes espresso beans darker.
Espresso is more stomach-friendly
With filter coffee, the water therefore has a lot of time to remove all bitter and tannins from the powder. The espresso only comes into contact with the ground coffee for a very short time. Therefore, aroma and flavors are well preserved or can only develop properly. Experts: “The espresso is more digestible and heart and stomach friendly than filter coffee!”
In addition, they usually have a smooth, shiny surface because the fats and oils they contain come to the surface. Coffee beans are medium brown and rather matt. Another difference: due to the longer roasting time, the acids contained are broken down.
Different preparation makes the difference - also in taste
In addition to the roasting, the preparation of the stimulating hot drinks also differs. Pressure is crucial for espresso. The water must flow through the previously pressed ground coffee at a minimum of 9 bar at a temperature of 88 to 94 degrees Celsius. Since the contact time is short, 25 to 30 seconds, the degree of grinding must be fine. The pressure creates a velvety-soft crema on the surface.
The specialty is served in a thick-walled, preheated cup. When preparing coffee, a higher water temperature is reached at 92 to 96 degrees Celsius, and no artificial pressure has to be generated. The ground coffee is coarser because it is brewed with water for minutes.
What has more caffeine?
By the way, it's a misconception that a cup of espresso gives your body more caffeine than a cup of coffee. The caffeine levels are similar. A cup of coffee with 150 ml contains between 50 and 100 mg of caffeine. A cup of 50 ml espresso is between 50 and 150 mg of caffeine. If you were to compare similar amounts of drink, the caffeine content of an espresso would be higher.
Does coffee draw water from the body?
Often a glass of water is served with an espresso because it is believed that coffee draws water from the body. However, a team of researchers found "that it makes no difference in the fluid balance of adults whether they consume their fluid needs through different drinks (which do not contain pure water) or drinks that include water." This means that coffee, among many other beverages, can support the fluid supply. The diuretic effect is also comparable to water.
No more than 4 cups a day!
You shouldn't drink more than four strong espressos or other comparable caffeinated drinks per day. More of the pick-me-up caffeine can harm your health. This is what researchers from the European Food Safety Authority (EFSA) have determined. According to the study, around 400 milligrams of caffeine per day are “harmless”. An espresso contains about 70 to 100 milligrams. (SB, Heike Kreutz, bzfe)
