How long does a good coffee bean last to grind? -How do coffee beans grind?

Coffee should be stored in a dry, cool place and never in the refrigerator to avoid moisture absorption. Coffee beans and ground coffee can be frozen. The only caveat is that when taking coffee out of the freezer, you need to avoid melting the frozen part and making the coffee in the bag wet. Americans think coffee is better kept in the refrigerator. However, it would not take more than a month. They take the coffee beans out of the freezer and grind them before they thaw.

Packaging for coffee storage

Tin cans can make coffee aroma stay longer. Plastic bags can also be stored, but less than tin cans. Coffee beans are sometimes sold in tin cans or plastic bags abroad. Vacuum packaging is more conducive to the storage of coffee, so that the original flavor more durable.

Once the oil-proof or tin-foil bag is opened, place the coffee beans or ground coffee in an airtight jar; the ground coffee will not mold quickly, but like the coffee beans, it will absorb the flavor in the air.

1. Coffee roasting is a technical activity.

Ever seen a coffee roaster but didn't know how it worked? Donahue outlines how to do it: "The first step in coffee roasting is to put the green coffee beans into a rotating drum, which has a strong hot air flow through it, and the temperature is as high as 400 degrees. Coffee beans in the sun drum undergo thousands of chemical and physical changes as the temperature gradually increases, especially the Mena reaction (think of a bread baking) and caramelization reaction, until the coffee beans reach a correct aroma and sweetness, and the coffee beans are almost baked. Open the door lid at the front of the machine and pour the heated coffee beans onto a cold pan, stirring until the temperature drops to room temperature.

2. Coffee roasting is an art.

When you cook or grill food, you don't just follow a recipe to make it delicious. In fact, food is an art that gourmets combine years of knowledge, experience and personal intuition, as is coffee roasting.

Kelso said: "There may be a misconception that digitally baking machines can solve all the problems, we just need to do some cleaning. In reality, however, even the best coffee roasters I've ever met roast coffee beans based on intuition they've built up over the years using data and technology."

3. Baking beans to different depths may also change how you brew them.

Although making a good cup of coffee has a lot to do with the fineness and amount of powder, you will find that you are accustomed to using different brewing equipment depending on the depth of roasting of coffee beans. Donahue said: "I can say that for the same light roast coffee beans, there are some brewing devices that are much better than other methods (any drip type, such as Chemex)." I personally prefer to press the beans to make softer, sweeter latino coffee beans because it retains the sugar content of the coffee intact.
