Roasting could be one of the most expensive coffee-making processes. This roaster from Amazon is not very cheap, but it seems worth making your coffee from the beginning (a bit). There are cheaper ones, like this one from Nuvo, which has pretty good reviews, but it's important not to scratch when it comes to a toaster. You will want a machine that executes the right temperature and time. Some people have managed to make some decent roasted coffee with a popcorn popper, believe it or not!
When it comes to temperatures for medium roasted coffee, it is essential to shoot for the “210-220 °C window”. At this temperature, it begins to extract oils from beans, but not at all. It is a black roasted coffee, the temperature rises and the time is prolonged. See a more in-depth conversation about dark roasted coffee here. Roasters have found that this temperature allows caramelization to begin without being too high. Towards the middle or end of this time and temperature window for the average roast, an audible cracking sound is heard.
From there, the roasted coffee beans are immediately moved to a cooling tray, as in a few minutes the average roast could turn dark. If not cooled properly, bean sugars can be compromised in a way that destroys the sweetness of the beans. Also, the beans will look visibly darker than a light roast by the end of the process.
It is not uncommon to have a mixture of dark roasted coffee, which means a rise in temperature and a slightly heavier body (but not as much as for a completely dark roast).
What Does Medium Roast Coffee Taste Like?
The brewing temperature that goes with frying an average roast creates an aroma that has become a preference for many people. This caramelization has begun, but the beans are not heated enough to be burned or to start too much "dark chocolate." "They have no oil on the surfaces of the beans", just like the lightly fried beans, which help with this flavor.
Medium roasted coffee has a "medium acidity and a fuller body". The temperature reveals aromas such as caramel, as well as "citrus, fruit, berries, acidity". A lot of people find it pleasant because caramelization has allowed a certain level of sweetness.
Does Medium Roast Have More Caffeine than Light or Dark Roast?
Most people would probably think that light roast has less caffeine, and dark roast has more, but it is too light. The reality is that open, dark, and medium roast cups have very similar amounts of caffeine. It is believed that this came from the idea that light beans are denser and dark beans are less dense, so the beans themselves have more caffeine because of this.
Once ground and prepared, they all come out with a sore throat in terms of caffeine content. If you really pinch money to make the most of your roast, something from the lighter end may have the least amount of caffeine. This means that the average roasts are as expected - in the middle!
Roasts Similar to Medium Roast
Roasts similar to Medium Breakfast mixes and regular roasts are quite popular, but don't let the name fool you. They're more likely than average roasts. It had become popular for having those roasts because of the supermarkets and Starbucks being stocked with them. Lots of cafes also offer a medium roast as their home mixes, but always ask about it before going to it. This is done to avoid surprising customers with the harsher flavors of a dark roast or with the ease of something at the other end of the frying temperatures.
