Making coffee is actually a very simple thing.

All you need is coffee beans and water, and that's it. But from such a simple combination, we can develop a variety of different brewing methods. Drip coffee, espresso and cold extract, for example, use basically the same ingredients, but they are very different drinks.

So when you're in a coffee shop, how do you choose? Do you want something sweeter? Or is it a little bitter? Do you want a quick pick-me-up or do you want to sit back and enjoy the slow work? Let's take a look at the 3 drinks in the title, which differ in taste, caffeine content and brewing method.

the espresso

Espresso is also made from ground coffee beans and hot water, but the process is a little more complicated than drip coffee. To make espresso, coffee beans are ground to a very fine powder and then pressed into a cake-like powder brick. Hot water is forced through the cake under high pressure, resulting in a small cup of coffee with a strong, bitter taste. When brewing drip coffee, the biggest influence on taste is the ratio of water to coffee powder, but in the world of espresso, any subtle factor can have a significant impact. The fineness of the ground coffee, the extraction time measured in seconds, and the amount of liquid flowing out can all determine whether the espresso is what you want. Espresso is generally more bitter than drip coffee, and has more than half the amount.

Espresso is small, usually just 2 ounces, but that doesn't mean espresso is low in caffeine.

In fact, espresso, as the name suggests, is a cup of very strong coffee. Espresso coffee contains about 50mg of caffeine per ounce. That's a far cry from the average 110mg of caffeine in a cup of drip coffee, an espresso that has far more caffeine per ounce than coffee brewed by other methods. In other words, just drink 2 ounces of espresso and you're consuming the same amount of caffeine as drinking one cup of drip coffee.

Many friends like to drink espresso coffee directly, but in fact espresso coffee is the most plastic, because whether latte or cappuccino or macchiato, the base material is espresso, plus different amounts of fresh milk and milk foam made

cold brew

There are several ways to make iced coffee: hand brewing should be the easiest way, you just need to brew hot coffee as usual, pour it on ice. But when you do this, you have to brew coffee with a higher concentration, or use ice cubes made from coffee, otherwise the finished product will be over-diluted and become very weak and watery. Therefore, many people like to make iced coffee by cold extraction, but the biggest problem is that cold extraction is the most time-consuming method of extracting coffee.

Like other coffee extracts, cold extraction uses ground coffee powder and water. The process is not complicated at all, but it takes a long time. You need to soak the ground coffee in water for 12 hours. Some friends even suggest soaking for 24 hours. The liquid and coffee grounds are then poured into a filter, allowing the liquid coffee to flow into a holding container while the grounds remain in the filter. Cold coffee is very different from regular hot coffee. Longer extraction times should make the product smoother and less acidic. Because caffeine is not easy to melt in cold water, most people will adjust the ratio of coffee and water, with more coffee to carry out cold extraction. The finished product will be a rich taste, high concentration coffee solution, usually diluted with milk and cold water before drinking.

What is mentioned here is the cold bubble method in cold extraction.

Cold coffee does not limit what coffee powder can be made.
