Drinking coffee could help to prevent obesity.
An espresso made with a moka doesn’t have the dense and creamy texture of a machine-made espresso, but it shouldn’t be too watery either. The first sign that you’re about to drink a good espresso is in the air. If it smells great as it’s brewing, that means you’re on the right track. Another element to consider while it’s still on the stove is its color. The first liquid to come out must be very dark; then, once it’s removed from the stove, a little foam should also come out, either hazelnut color or brown, depending on the ground of coffee you chose to use.
Under brewed coffee also tastes a bit salty. A certain aroma and body will already be present in it, because both also come from oils and fats. However, these nice qualities will be overwhelmed with sourness. Under extracted coffee will also have little to no finish. Finish is the aftertaste that lingers for a minute or so after taking a sip. This is why it is perfectly natural to savor even a small cup of a well-brewed coffee over time, by taking small sips. A taste of under brewed coffee, lacking finish, will vanish right after it is swallowed. Under brewed coffee will also lack brightness or complex acidity.
This is one of the first times researchers have been able to boost brown fat activity in humans, said Professor Michael Symonds, who co-led the study.This type of fat helps to generate body heat by burning calories, which in turn reduces individuals’ Body Mass Index (BMI) and can improve blood sugar control.The stage in which bitter insoluble components become bitter soluble ones is the last part of the coffee extraction. At this point these components start to dissolve into our coffee more and more. It is mostly the fibers in the coffee that contribute to the bitterness.
The color of the espresso once it’s in your cup depends on the blend: if you used 100% arabica, it will be lighter, whereas if you used a mix of arabica and robusta it will be a bit browner, but the shade should definitely have some consistency. Before you drink it, you should carry out one last check by rotating the cup to make sure there’s not an excessive amount of coffee grounds at the bottom. If that’s the case, it means that the coffee grounds were too fine, or the filter hadn’t been cleaned well, or that it’s time to replace your moka.
A cup of a good coffee will harmoniously combine sweetness, aroma, body, bright acidity and a hint of bitterness and saltiness. This will happen when everything falls into place: grind size, water temperature, water-to-coffee ratio, etc. The brewing process of an optimal cup will stop at that perfect spot, just before over extraction will begin. In a perfect world a cup of coffee will have extracted all that we want from the beans.
