Is there more caffeine in espresso or hand-brewed coffee?

Many friends come to Qianjie Cafe with bleary eyes when they go to work in the morning and say, "I want a latte and espresso with extra powder. I'm so sleepy." Yes, many people will think that I will wake up as long as I drink a little more espresso. Is that so? This time on the front street, let's talk about the caffeine content of espresso.

What does caffeine content depend on?

The amount of caffeine depends on the variety of coffee beans. Arabica coffee beans contain about 0.8% Murray 1.5% caffeine. Robusta caffeine content 1.7% Murray 3%.

Will the degree of roasting affect the caffeine content of this coffee bean?

When browsing through the materials, Qianjie saw that coffee practitioners had used the same variety of beans for 25 minutes of roasting for 25 minutes more than 10 years ago, including: very shallow (JQ); shallow (Q); shallow to moderate (QZ); moderate (Z); medium depth (ZS); depth (S); extreme depth (JS); French heavy (FZ). In the changes of various chemical composition, it was found that caffeine did not change much, about 1.4%, whether it was shallow baking or deep baking.

So the caffeine content of a cup of coffee depends on the way the coffee is made.

The content of Italian concentrated caffeine

Many people believe that a cup of espresso contains more caffeine than a cup of drip coffee. Actually, this is wrong. Espresso contains 64-75 mg of caffeine per 30 ml, so a single cup of espresso contains less caffeine than a single cup of drip coffee.

In addition, espresso is usually diluted with water, milk or cream to make American or milk-based coffee. A large latte contains 591 milliliters and contains three espresso cups. According to this calculation, the caffeine content is 225 mg. By contrast, a cup of drip coffee of the same size contains almost twice as much caffeine.

Caffeine content of drip coffee (hand brewed coffee)

The caffeine content of drip coffee (hand brewed coffee) depends on the brewing method, size and concentration. A cup of 237ml drip filter coffee contains about 95-163mg caffeine, which is 1.5-2 times more caffeine than espresso. So refreshing buddies can come to the front street to try our home-baked freshly baked hand-brewed coffee to start the day.

Qianjie Coffee is currently making espresso using a blend of beans treated in sherry buckets and sun-treated Yegashifi red cherries. 60% of the Honduran sherry barrel coffee beans provide flavor and mellow thickness for this mixed bean, and 40% of the sun Yega Sheffield provides more aroma and acidity.
