Is the coffee bean oil more fresh and delicious? Do oiled coffee beans have more calories? is it more suitable for Italian style or hand flushing? Let Qianjie answer your questions and questions today.

Myth 1: oiled coffee is more fresh.

Equating oily with fresh seems like a smart way to bake coffee, doesn't it? When beans have that luster, they look very shiny and sexy! However, this is not a foolproof way to judge whether coffee has been kept for a period of time, because dark-roasted beans naturally show more oil faster than light-roasted beans. Decaffeinated also tends to be a bit tricky: seeds tend to have weak cellulose because of the trauma they suffer in the decaffeinated process. ) your best way is to find a baking date on the beans, because there is no perfect equation to calculate how much oil may appear in a certain amount of weeks or even months.

Myth 2: coffee oil is part of what makes coffee delicious.

Like any oil, prolonged exposure to light and oxygen (and heat) can produce rancid odors and odors, so if oil is the result of stagnant coffee sales, it will never contribute to the delicacy of the cup. It also means that you should be especially careful with your deep-baked foods: storing them in a cool, dark place will be the best way to prevent them from going bad.

Myth 3: the coffee extracted from oily beans has a higher fat content.

Because oil is insoluble in water, most extraction methods leave lipids, especially in the filter cup of hand-brewed coffee. According to a 2006 report by Karl Speer and Isabelle K ö lling-Speer, "the lipid portion of coffee beans": "filtered coffee prepared using an ordinary household coffee mechanism has a lipid content of less than 0.2 per cent. By contrast, in the preparation of espresso, 1% to 2% of lipids. From finely ground espresso into the drink. "

Paper filters are thought to be much more efficient in retaining and absorbing coffee oil during brewing, while perforated or reticulated metal (such as in a portable filter basket on an espresso machine, or a screen on a French filter press) has larger pores and therefore allows more oil to pass through the final drink.

However, this mainly means that espresso (or French filter press) tastes heavier or more creamy-not necessarily because the coffee itself is much higher in calories or fat. Filtered brewed coffee may contain 1 to 3 calories per 8 ounce serving, while each 2 ounce serving of espresso contains about 5 calories, mainly due to the amount of oil allowed into the finished drink. Consider that the consistency of espresso comes from filtered coffee with a lower concentration. )
