When it comes to coffee, the bitter taste is often many people's first impression of it, but in fact, the raw beans of coffee contain a certain proportion of sucrose, so generally speaking, the final rhyme of drinking coffee comes from this. and many people think that making coffee requires high temperature to brew coffee, but to make a good coffee actually needs a little cooler water, these three coffee secrets will be sorted out. Coffee lovers must know!

1. Coffee contains sucrose and should be sweet.

Because coffee is a fruit, raw beans contain sucrose, and coffee beans produce caramelization at a temperature of about 170 ~ 200 degrees, which is about the temperature when coffee beans explode. The reaction of caramel will produce the aroma of fire, the taste and color of caramel, as well as some fragrant substances such as maltol and furan compounds, but overroasting will cause carbonization and bitterness of the coffee. If the caramelization is not enough, it is lack of aroma and lack of hierarchical sense.

two。 The most suitable temperature for brewing coffee is 80 ~ 85 degrees.

It is a misconception that coffee can only be brewed in boiling hot water, because coffee is divided into three different molecules, small, medium and small, and the taste of macromolecules is more messy, so most people prefer the taste of medium and small molecules. So the secret to making a good coffee is to let the small molecules be released quickly, so the action should be fast and the temperature should not be too high, because the hotter the extract is, the easier it is to release it. Will help macromolecules dissolve, boiling water is not suitable for making coffee, the most suitable temperature is 80 ~ 85 degrees, higher than 85 degrees will make defective coffee.

3. Don't grind the coffee when you buy it. You can't taste good coffee when you catch a cold.

Never drink coffee when you have a cold, because 40% of what we drink is taste and 60% is smell. It is reasonable to prove that when coffee beans are grinded, do not grind coffee beans, because coffee beans will lose all their aroma within 30 minutes. So if you want to make your own coffee, one of the most necessary things is the bean grinder.
