Where there are people and differences, there must be a chain of contempt, especially in the automobile industry, but it does not rule out that merchants deliberately speculate and even milk tea sellers get in the way.
In fact, most consumers don't love coffee enough for them to look up books. What's more, they don't need to know the process, just tell me which one is good.
And really good coffee, your handling of every detail. The baking degree and extraction method of beans, and even the quality of boutique cafes are uneven. Not everyone is a master, nor are all masters masterpieces every time.
Most importantly, everyone has different preferences for coffee. For example, I like bitter taste, but I can't say it's better than sweet taste and sour taste. Even "God's cup of coffee" is only a subjective feeling.
But this does not hinder our constant pursuit of good coffee. Let me sort out the coffee white system, the knowledge about coffee beans, grinding and brewing, and teach you how to make rich and mellow coffee in the simplest way.
0 1 How to choose and store coffee beans?
If you want to list the types of coffee beans in the world, it is estimated that you can't finish it in one breath. But a simple classification can be divided into two categories: Arabica and Robusta.
From the price point of view, Allah is more expensive than Kakapu, about twice as expensive as Robusta. In terms of composition, Arabica has low caffeine content, but high fat and sugar content, so it has a soft taste.
Because Arabica has low chlorogenic acid (antioxidant), the planting conditions are harsh. Generally, in high altitude areas, the fruit ripens slowly and the comprehensive yield is relatively low. Things are rare, so the price is more advanced.
However, the roasting degree of coffee beans is an important way to adjust the taste of coffee. For example, if the roasting degree is shallow, the coffee will be sour, and if the roasting degree is high, the bitterness of coffee will be more prominent.
Besides looking at the origin and variety of coffee beans, there is another mistake that beginners are most likely to make to avoid. Brew your own coffee, it is best not to buy coffee powder directly, or to grind coffee powder in batches for preservation. When buying freshly roasted coffee beans, it is best to roast them within 3 days, which is too long and the quality is unreliable (self-roasting detour). If you want to drink good coffee, don't save trouble. No matter how advanced the way you store roasted coffee, it will weaken the flavor of coffee for a long time.
How to extract coffee is ideal?
In addition to the choice of coffee beans, the ideal extraction is also the only way for a good cup of coffee. Whether it is hand washing, drip filtration or espresso, great attention is paid to the effect of extraction. According to the different equipments that coffee lovers often use, coffee extraction can be divided into five ways and eight major equipments.
Pressure extraction
Common pressure extraction includes espresso machines and mocha pots. The extraction of espresso usually takes only 20-30 seconds, and coffee can be brewed at 9 atmospheric pressure, which is almost necessary for all coffee shops. Through high-pressure hot water infiltration of coffee powder, according to the fineness and compactness of coffee powder grinding, different tastes of the same coffee powder are also different.
If the coffee powder is coarse, the landfill is loose, the time for infiltrating the coffee powder is short, and the extraction is not acid enough. On the contrary, excessive extraction becomes a bitter Chinese herbal medicine. Therefore, the production process of espresso requires many trial and error to master the purity of extraction and personal preference.
