Coffee is often jokingly called "foreigner's soy milk." Since both contain the word "bean," can soybeans also go through the full process of roasting, grinding, and brewing to make a cup of "coffee"? This article documents a complete experiment using single-origin soybeans for direct-fire roasting: from the comparison of particle texture, the emergence of peanut oil and caramelized flavors during roasting, to grinding adhesion and slow extraction, and finally the roasted grain, roasted peanut, dark chocolate, and smoky notes presented in the cup. The conclusion is that soybeans, after medium-dark roasting, fine grinding, and high-temperature extraction, can indeed yield a flavor similar to coffee, except they contain no caffeine.

Understanding this school will change how you think about what "coffee should [more…]

The roast level of coffee beans directly affects the flavor expression in the final cup.

The same single-origin bean can taste completely different as a pour-over versus an SOE. The roast level plays a key role here—a light roast preserves the floral and fruity acidity, but under pressurized extraction it can turn sharp and prickly on the tongue; a dark roast brings a rich, mellow caramel note, but it easily masks the character of the origin. So what roast level should SOE actually use? This article starts from roast chemistry, analyzing how the Maillard reaction and caramelization shape coffee flavor, sorting out the flavor directions corresponding to light, medium, and dark roast levels, and then answers the roasting-selection challenge for making SOE from single-origin beans, and offers four Front Street Coffee beans suitable for SOE, covering four styles: tropical fruit, hazelnut and sugarcane, fermented fruit, and chocolate creamy peanut.
