Today, one way degassing valve for coffee new fans to solve some small coffee new doubts, coffee is not necessarily hot drink? In fact, the current coffee is not. The quality of the early coffee beans was not as high as it is now, so after the cold, the flawed flavor was often highlighted, and then everyone would think that the coffee would not taste good if it was cold. Good coffee, after the cold, the same will have a good flavor performance. Conversely, if a cup of coffee has a good flavor when it is hot, it becomes irritating when it is cold.
Hand brewing coffee must be better than machine brewing?
This is a big misconception. But if we need a cup of rich, full-fledged coffee, or if we need a coffee that has multiple variations, we have to choose the machine brewed espresso to get a cup of richly flavored coffee. This is how the ruler is shorter and the director better.
The fresh coffee beans, the better?
In general, we still think that the more fresh the coffee beans, the better, because the coffee cooked beans contain a lot of volatile aromatic substances, the longer the storage, the more volatile flavor, which is an irreversible and cannot be completely blocked reaction. However, it does not mean that coffee beans are just baked and brewing is the best. Coffee cannot be too fresh. Part of the coffee, it takes some time (2 to 3 days) to complete an exhaust process, the process of baking into the coffee beans inside the gas discharge, this process we call ‘raising beans.’ Only the ‘beans’ after the completion of the coffee beans, is the most full of aroma and flavor of the peak state.
