1. Choose freshly roasted coffee beans

If you want a good cup of coffee, the freshness of coffee beans is particularly important. Although coffee beans are in a dry state and can be stored for a long time, the shelf life of the flavor is indeed very short! The best taste period for a packet of freshly roasted coffee beans is about 30 days after the baking completion date.

After the coffee beans are roasted, the carbon dioxide will be reduced over time, and the flavor will be carried away by carbon dioxide, so the longer the coffee is kept, the less the flavor will be. Nowadays, many brands of freshly roasted coffee beans offer regular discounts, so we don't need to store too many coffee beans, drink them and then buy them to keep them fresh.

two。 Choose coffee beans from different roasting / producing areas according to your own flavor preferences.

Coffee beans in different coffee producing areas have their own unique coffee flavor characteristics, and the sour, sweet and bitter performance of coffee beans with different roasting degrees will be different.

If you like coffee beans with obvious sour taste and refreshing taste, it is recommended to choose light / medium-light roasted coffee beans from Africa (such as Ethiopia, Kenya), which usually have citrus acidity, berry-like sour and sweet taste, and tea-like sweet and sour coffee.

If you like soft, sour, full-bodied coffee beans, it is recommended to choose moderately roasted coffee beans from Central and South America (such as Guatemala, Colombia, Costa Rica, Panama). It usually has soft acidity, nutty taste and caramel finish and sweetness.

If you like low-acid, slightly bitter, rich coffee beans, it is recommended to choose medium-deep roasted coffee beans from Yunnan, China, which usually have plum-like acidity, nutty taste, brown sugar-like sweetness and tea-like sweetness; or choose medium-and deep-roasted coffee beans from Brazil, which usually have rich nutty taste, smooth taste and sugar-like sweetness.

If you like coffee beans with high thickness and strong taste, you can try coffee beans from medium-and deep-roasted islands (such as the Blue Mountains of Jamaica and Papua New Guinea), which usually show a balance between sweet and sour and a rich and solid taste; or choose Indonesian Sumatra Mantenin coffee beans, which usually show a mellow flavor of herbs, spices, dark chocolate and obvious sweetness.

3. Suitable degree of grinding

Daily purchase of freshly roasted coffee beans, it is recommended to grind before brewing. Because the increase in the cut of coffee after grinding will accelerate the dissipation of flavor. The solubility of substances in different roasted coffee beans will be different ~ so the coffee with a balanced taste can be extracted only if it is ground into particles of the right thickness.

Medium and shallow roasted coffee beans are recommended to be ground to medium fine / fine sugar size (China 20 standard sieve filter 80%); moderately roasted coffee beans are recommended to be ground to medium / white granulated sugar size (China 20 standard sieve sieve 75%); medium and deep roasted coffee beans are recommended to be ground to medium coarse / coarse sugar size (China 20 standard sieve filter 70%).

4. Measure the water temperature of each coffee brewing

Many friends will brew coffee directly with freshly boiled hot water at home, or choose to rely on experience to dry for a few minutes to cool down, but this experience is often unreliable because room temperature and water volume are usually constantly changing. the temperature of each brewing is unstable. Therefore, it is very necessary to use a thermometer to measure water temperature.

Generally speaking, brewing medium to medium roasted coffee beans, with the above recommended grinding degree, the water temperature is recommended in the range of 90-92 degrees Celsius. Brewing medium-deep roasted coffee beans, with the above recommended grinding degree, the water temperature is recommended in the range of 87-89 degrees Celsius.

5. Appropriate ratio of powder to water

The focus of the brewing ratio is "quantification". A simple electronic scale can solve many problems. The electronic scale is responsible for weighing coffee beans and the weight of water injection, calculating the brewing time, and the data of each parameter can be duplicated. At the same time, ensure the stability of each coffee brew.

In general, the coffee brewed out at 1:15 is more balanced. This is just the recommended brewing ratio. If you think it is light, it can be reduced to 1:13-1 Groupe 14; if you think it is strong, it can be raised to 1:16-1:17.

The ratio of powdered water to the amount of water to be injected into coffee. For example, if you use 15g coffee powder for brewing coffee and brew it at 1:15, you need to inject 225g of water and finish the extraction after all the water passes through the coffee particles.
