Water for grinding and brewing coffee powder

Follow the caf é (Wechat official account vdailycom) and found that Beautiful Cafe opened a small shop of its own.

Grinding of coffee beans

Freshly ground coffee powder smells refreshing, and sometimes it's worth buying a bean grinder just to smell it. Compared to buying pre-ground coffee powder, grinding coffee beans at home can make a big difference to the coffee you drink!

The purpose of grinding coffee is to make the beans produce enough surface area before brewing to extract the ingredients sealed in the beans and then make a good cup of coffee.

Take unground raw beans and you will get a very thin cup of coffee water. The finer the coffee beans are ground, the larger the surface area will theoretically be, so that the coffee can be boiled more quickly.

This principle is important, especially when you have to decide how fine the coffee powder should be ground for different brewing methods. In fact, the thickness of coffee powder corresponds to the length of cooking time, so the consistency of grinding particles is very important. Grinding will increase the surface area of coffee exposed to the air, indicating that the aging effect of coffee will be accelerated, so the ideal grinding time is the moment before brewing.

Many coffee lovers often want to upgrade their equipment, and I strongly recommend upgrading your bean grinder first. Higher-priced bean grinders usually have better motors and plates to produce more consistent grinding particles. With a high-end bean grinder and a small household espresso machine, you can make a better cup of coffee.

Cooking water Water For Brewing

Water plays a vital role in making a good cup of coffee. Water is an important ingredient in a cup of coffee, accounting for about 90% of espresso and 98.5% of follicular coffee. If the water used to make coffee is not delicious in the first place, the coffee can never be delicious. In the brewing process, water acts as a solvent and is responsible for extracting the flavor components from coffee powder. The hardness and mineral content of water will affect the extraction efficiency of coffee, so water quality is very important.

The hardness of water has a great influence on the interaction between hot water and coffee powder. Ideal water contains a small amount of hardness, but if the content is too high, it is not suitable for making coffee.

Coffee made from high-hardness water lacks a sense of hierarchy, sweetness and complexity, and from a practical point of view, the scale accumulated in any coffee machine that requires hot water will soon cause machine failure. Apart from being delicious and having only a small amount of hardness, we don't want water to contain too much else-except for relatively low levels of minerals.

If you live in an area where the water quality is moderately soft, just add a water filter to improve the taste of the water. If you live in areas where the water quality is hard, the best solution now is to buy bottled drinking water and make coffee. Supermarket brand bottled water is usually lower in mineral content than big brands.
