1. Coffee beans

pour-over coffee.

Usually single-origin coffee beans are used as the brewing material, with roast levels ranging from light, medium to dark roasts.

Espresso.

The coffee shop's Italian recipe, called House Blend, is usually heavily used in espresso drinks such as cappuccinos, americanos, and lattes, and most are darker roasted to pair with milk and hot water. This coffee can only be ground with a professional grinder, which is also an important foundation and key to making high-quality espresso.

Similar to other addictive substances, caffeine can also be addictive to your body. This is because regular, consistent caffeine consumption can cause changes in brain chemistry. For example, your brain cells may start making more adenosine receptors to compensate for those blocked by caffeine. In turn, more receptors require you to consume more caffeine to achieve the same "caffeine fix." This explains how regular coffee drinkers can build tolerance over time.

On the other hand, suddenly cutting off your caffeine supply suddenly floods your brain with adenosine-binding free receptors. This produces an intense feeling of tiredness and is thought to be the main reason behind caffeine withdrawal symptoms, which are often triggered by cold turkey. While daily caffeine intake can lead to a physical addiction, the act of regular coffee consumption may promote behavioral addiction. To avoid these situations, you can use a caffeine calculator to record the caffeine content of each cup of coffee.

2. Preparation method

pour-over coffee.

Basically, most pour coffee is extracted with filter cups. That is, it is extracted in the state of atmospheric pressure. Even with a brewing device like a moka pot or an Aeropress, the extraction pressure can only reach about three atmospheres at most.

Espresso.

Using an espresso machine to extract, the pressure of the machine will make the extraction state reach nine atmospheres, and the coffee powder in the filter cup will bear the heavy pressure of 130PSI, which will release a lot of coffee substances, with a strong taste, suitable for use with milk. Iron, or add water to make Americano.

Do you know what is macchiato exactly? It was originally invented for an afternoon espresso. Another variation of espresso, the cappuccino, is better for a morning pick-me-up. Macchiato offers coffee lovers a great alternative between espresso and cappuccino. It has a stronger flavor than cappuccino because it has less milk, but is lighter than espresso.

3. Differences in service volume

pour-over coffee.

A typical serving size is about 5-10 fluid ounces. (Can be increased or decreased according to the ratio of coffee and water)

Espresso.

A typical serving size is about 1-2 ounces. (Can be increased or decreased according to the ratio of coffee and water)

4. Differences in caffeine

If the coffee grounds and grinds are the same size, since caffeine is a water-soluble substance, the longer the brew time, the more caffeine will be released.

The brew time for single-origin coffee is usually 1-3 minutes. The brew time for espresso is usually 20-30 seconds, so with the same ground and grind size, single-origin coffee will have higher caffeine content.

It can be seen that iced coffee and cold brew coffee have much higher caffeine content than other coffees.

It can be seen that there is a big difference in the concentration of coffee brewed by pouring coffee and espresso. After adding milk to single-origin coffee, the aroma and taste of the coffee itself will be covered by milk, which is not suitable for blending.

5. Differences in Conclusions

Can single origin coffee be brewed by machine? Yes, but all brewing factors need to be adjusted. Find the right brewing parameters to match single-origin coffee beans, and you can also brew high-quality single-origin espresso.

Can espresso beans be hand washed? This is also possible. However, parameters such as water temperature and grind size should also be adjusted for darker roasted espresso beans.

Remember, all brewing methods and utensils are designed to provide better coffee. Coffee is for people! Coffee makes everything possible.
