Are you new to the world of specialty coffee? Do you ever wonder why you can’t obtain the same high-quality coffee at home? Did you know that picking the right bean is just as essential as having the right equipment and training to achieve your desired coffee recipe?
Of course, coffee is a question of personal preference, but there are some principles to follow if you want to get the most flavor out of your beans. Here are what you would like to pay attention when shopping for freshly roasted coffee beans:
Verify If The Coffee Bean Has A Glossy Appearance
Coffee beans that are roasted with intensive high-temperature drain moisture from the centre of the beans while synchronously drawing out the shiny oil on its surface. The oil-like substance is not the natural oil that you may imagine, but it is worn off after being exposed to the air, so if you put it out for a longer time, it will become less greasy.
The amount that coffee beans can produce its oil definitely depends on the roasting process and technique. The dark roast will provide this glossy look, whereas the light roast won’t make this level of oiliness.
Is There Any Residue?
If your coffee beans leave you residue when grabbing a handful of amounts on your hands, or you can see its greasiness in the beans’ internal bags, then it can be regarded as “freshly roasted.”
Because lighter roasts aren’t as greasy as darker roasts, so you do not expect to get as much residue.
Is There A Valve in The Sealed Packaging Bag?
A ton of carbon dioxide (CO2) will be automatically pulled out if the beans are roasted in high heat and cooled down. It can last from a few days to a couple of weeks, deemed a “degassing period.”
Typically, the manufacturers create one-way air valves to the vacuum-sealed bags to release CO2 during its degassing process; otherwise, it will be at risk of an explosion like a balloon. If you cannot find those valves in your sealed bags, it means that coffee beans do not have an emission of CO2 and are more likely not to be freshly roasted.
If you buy a bulk amount of coffee beans, you can put half-cup beans in a resealable bag. Then, you squeeze out the air and place them on the kitchen counter all night long. If those beans are freshly roasted between 7 to 10 days, the bag will blow up due to carbon dioxide outgassing.
Know The Origin of Coffee Grown
Different coffee flavors come from various regions and where they initially plant the coffee seeds. For example, Central America has a smoother, nutty but not sour taste, while South America gets you a little sweet and mellow taste, particularly its Columbian coffee.
Furthermore, Asia has lower acidity and woody-earth coffee taste while Africa gets you a wine-like and fruity taste. With your different roasting techniques, it will make your coffee’s unique attribute sparkle drastically.
