the roasting of the coffee beans in

The more common distinctions are Cinnamon Roast, City Roast, Full-City Roast, Vienna Roast, Italian Roast and French Roast.

The selection of raw beans, mastering the characteristics and structure of baking machines, and patient repeated testing are the only ways for a successful baker. The change of air and humidity in the working environment, the appropriate timing of raw materials entering the boiler, the precise control of heating procedures and time, how to adjust the exhaust valve, the cooling system and procedures, and even the calculation of the movement rate of each coffee bean in the boiler, all fully endow coffee with active vitality.

How to preserve coffee beans

The beans that have not yet been roasted or fried sink better, and once the coffee beans are roasted, they slowly lose their flavor, and after two weeks the flavor is gone. So buy a small amount at a time, or buy a small amount of coffee that has been ground. If you order coffee from a specialty coffee shop, it's best to buy unground beans. Choose the right packaging or container, stored in the appropriate space, is the case, but fresh coffee is extremely sensitive to the storage environment, in recent years experts strongly recommend the use of aluminum foil packaging materials (opaque) with one-way exhaust valve, for domestic and foreign manufacturers praised and recognized, blocking the invasion of oxygen and able to discharge carbon dioxide, greatly extending the honeymoon period of tasting fresh coffee. As for storage, I think it is only necessary to place it in a shady place that is not easy to damp and direct sunlight. Refrigeration or freezing is not absolutely ideal. Excessive shrinkage of fiber, condensation of benign oils, peculiar smell in the refrigerator, and high and low temperature difference during extraction are all thought-provoking.

A good place to store coffee

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.

Storage of instant coffee

Instant coffee bags are a recent development of processed foods for roasted and ground coffee. Their thin aluminum material helps preserve the original aroma of coffee to the greatest extent.
