Many coffee enthusiasts will notice that with the same beans and the same machine, the flow rate of espresso can change every few hours or even every few dozen minutes, sometimes fast and sometimes slow. Beyond the aging characteristics of the coffee beans themselves, there are actually quite a few easily overlooked hidden factors influencing the extraction results, including residual grounds in the grinder's chute, temperature fluctuations in the espresso machine's hot water, the state of the pump pressure, changes in ambient temperature, humidity and air pressure, and whether the grinder's hopper pressure remains stable in a café setting. Front Street will analyze these factors' mechanisms of influence on espresso extraction one by one, and provide corresponding improvement solutions to help everyone reduce unnecessary adjustments and make their output more consistent.

When we heat the moka pot, the water in the bottom chamber heats up first. [more…]

Many coffee enthusiasts considering a Moka pot wonder: can it replace an espresso machine? After all, espresso machines are quite expensive, while Moka pots are much more affordable. The "replacement" mentioned here is not a complete functional substitute, but rather whether the coffee made with a Moka pot can stand in for espresso in making drinks. Although both use pressurized extraction and produce a concentration higher than single-origin coffee, what are the actual differences in performance? Front Street Coffee analyzes this through comparative experiments, examining concentration, crema, and mouthfeel one by one, and explains that the Moka pot's maximum pressure is only about 3 bar, while an espresso machine can reach 9 bar, which determines that it cannot replicate the thick, heavy texture of espresso. However, the Moka pot was never designed to replace the espresso machine; its portability, ease of use, and affordability are enough to meet light daily needs. [more…]

The official recommended method for the AeroPress is actually the standard (upright) brewing orientation, but many coffee enthusiasts are more familiar with the inverted method. So how should you choose your grind size for standard orientation brewing? And what flavor differences do different grind sizes bring? In this article, we use Front Street Coffee's Panama Washed Butterfly as the test bean, selecting three grind settings—BG 5M, BG 5R, and BG 6M—and conduct a standard orientation brewing comparison while keeping water temperature, coffee-to-water ratio, and technique fixed, evaluating each one across aroma, acidity, sweetness, cleanliness, and other dimensions. The conclusion: just like the inverted method, standard orientation brewing can reference the grind range used for pour-over, and the unique oily mouthfeel and smooth texture that come from pressure extraction are exactly what makes the AeroPress so appealing.

When making espresso, does tamping pressure actually affect the final taste? Front Street Coffee has been asked this question many times. To provide an answer, Front Street Coffee used 20g of coffee grounds and a target liquid weight of 40ml, extracting three espressos each with light tamping at 2kg, heavy tamping at 18kg, and no tamping at all, then compared extraction times and flavor performance. The results surprised many: the extraction times for the three methods were almost identical, and the tastes were hard to distinguish. The key behind this lies in how the coffee machine's 9bar pressure actually works. Starting from experimental data, this article will clarify the real impact of tamping pressure and explain why even distribution of grounds is far more important than forceful tamping. [more…]

Espresso, with its golden crema and rich, full-bodied flavor, has become a favorite among many coffee lovers.
