Coffee bean freshness and best flavor

·Freshness and best flavor

Coffee flavor is best on the first day after roasting, and after that time, coffee flavor declines cruelly and rapidly. Because after roasting, coffee beans themselves will release carbon dioxide, blocking the attack of oxidation, but after the emission of carbon dioxide during the fine coffee flavor oil will be oxidized and taste. Therefore, for coffee lovers, the aroma of freshly roasted coffee beans is undoubtedly the biggest reason why they choose to roast their own coffee beans.

Understandably, if the coffee beans are roasted in the store after appointment, or if the roasting location is close, you may be able to buy fresh coffee beans; however, due to the rapid expansion of regional and national specialty coffee chains, the coffee beans they use may have been roasted thousands of miles away, and it has been in your hands for God knows how many days! However, the coffee beans sold in these chain boutique cafes are not completely useless. At least it is fresher than pre-ground coffee or canned coffee, but it is definitely not as fresh as the coffee roasted in the kitchen at home!

What is certain, however, is that people drank their own or store-roasted coffee beans as freshly roasted, and these ancient, home-roasted beans performed slightly better than today's instant coffee and cheap canned coffee powder.

·Personal satisfaction

Roasting coffee beans at home can give us a sense of hands-on satisfaction, because we grew up in a purely consumerist society, and once we can unlock the mystery of roasting beans through our own hands (in fact, we have been deceived for a long time), how successful it is! Roasting coffee beans at home is an art. Perhaps it should be said that it is a non-mainstream art, but it can be a very fulfilling art.

·Save money

Obviously, this factor is more important to some people than others. Roasting your own coffee beans at home can save you between 25% and 50% depending on how and where you buy them. You can find the instructions for buying green coffee beans in the Related Resources section.

·Become a coffee expert

To really understand a coffee bean, you have to roast it yourself! In addition, once you start roasting your own coffee beans at home, it's possible to develop a personal "green bean collection." Unroasted green coffee beans are less uncertain about preservation. After one to two years of storage and reroasting, the flavor will vary a little, but it will still taste interesting, and even after a few years of roasting, it will still be suitable for drinking. As long as you store it correctly, some coffee beans will even have better performance after aging. So you can stock up on a few of your favorite coffee beans and choose which ones to roast on a given day, depending on your mood or the taste preferences of your visitors.
