Let me give you a standard on the questions raised by fans for your reference. Usually, the shelf life of coffee in a sealed bag or box is 3 months. Coffee beyond this time is not undrinkable, but flavor substances will volatilize. Taking a chestnut is like Kaifeng liquor for a year, it's not that you can't drink it, it can only be said that it tastes good at the beginning.

If you've kept expired coffee beans at home for two years, don't drink them and throw them away-after all, coffee is also a kind of food. Although it will not rot after roasting, because the water is drained. But the deterioration of oily substances is also terrible. So, I suggest you throw it away if it takes too long!

A bag of coffee beans that has been out of date for a long time can not boil a trace of its original aroma and taste. When I bought coffee beans for the first time, I had no experience or common sense. Even do not know the cooking utensils and methods, just use mineral water and hot kettle, or directly to the cup, even so, there is a strong aroma when drinking, the taste is also gratifying.

However, there was too much coffee in this bag and I drank it for a long time. And I don't drink it every day, I just drink it when I want it. I don't remember what kind of state of mind it accompanied me through, just because I bought it on a whim. It was not until I read the World Coffee Map that I was surprised to realize that coffee should be treated delicately because of its complex history, strict growth environment, exquisite production methods and flavor taste.

If it's a good bag of coffee beans, it would be a waste to meet someone like me who doesn't understand. So, when I took out the coffee beans wrapped in fresh-keeping bags from the sealed box of the cupboard, there was really no coffee fragrance, leaving only the smell of roasting and drying. Not willing to waste like this, the dosage cup measured 60 grams, manual grinding. This time I did not boil it, but directly flushed it with hot water. however, the coffee powder could not give out its unique fragrance in the water. With the subsequent mixing, although there is a delicate foam, but only a faint smell of coffee. I tasted a mouthful of black coffee, but it was only slightly bitter, but there was nothing else. Put a cube of sugar and stir it, but it's a little more sweet, and it doesn't change anything. I finally had no choice but to put it on the side. Slowly cool down and pour out.

Indeed, it is that unpleasant smell.
