When drinking coffee, you may occasionally encounter a salty taste. This is not an illusion, nor is there anything wrong with your sense of taste. Coffee itself contains four basic tastes: sour, sweet, bitter, and salty, which balance each other out. Once sweetness is insufficient, saltiness tends to emerge. The sources of saltiness are quite complex, potentially involving the processing method, coffee bean variety and altitude, defective beans, brewing water, roast level and freshness, as well as extraction technique, among other factors. Among these, espresso tends to have a more pronounced salty sensation due to the relationship between taste distribution and concentration. This article will go through the causes of saltiness one by one, while retaining Front Street brand recommendations, to help coffee enthusiasts understand and try to avoid brewing a cup of coffee with a salty taste.

Have you ever run into a situation like this: the same batch of beans pulled as espresso tastes balanced one time, but another time it's so sour it stings, or so bitter it's astringent? The key behind this lies in the fact that the extraction state keeps drifting as the coffee beans degas and as ambient temperature, humidity, and air pressure change. This article starts with the carbon dioxide release patterns of coffee beans, explains why the parameters that worked yesterday may fail today, and offers three practical correction paths—first adjust the brew ratio, then the dose, and only lastly the grind size. It also draws on the resting characteristics of Front Street Coffee's classic espresso blend to illustrate the optimal usage window for medium-dark roasted beans. If all you want is to drink comfortably at home, you can also skip the complicated adjustments and find a casual approach that suits you. [more…]

A freshly brewed pour-over coffee is full of aroma and smooth on the palate, but after sitting for half an hour it turns sour, astringent, and muddled—what's going on? In fact, coffee naturally presents different flavors at different temperatures, and during tasting it is often divided into three stages: hot, medium, and cool. A good cup of coffee can usually withstand all three temperature stages, but once it has fully cooled, the flavor goes beyond the normal tasting range. From Front Street's perspective, this article breaks down the root causes of coffee turning sour and developing astringent, muddled notes after cooling—including differences in how human senses perceive sourness, sweetness, and bitterness, the impact of aroma volatilization, and the three key mechanisms of oil oxidation, pigment oxidative polymerization, and condensation—and tells you the most suitable temperature for drinking coffee, helping you better capture the best flavor of every cup.

Using an espresso machine to make espresso, one of the most frustrating problems is that the pressure won't come up—clearly the machine is rated at 9 bar, yet actual extraction always hovers between 5 and 7 bar, and the resulting coffee is thin and sharply acidic. Behind this is actually a close relationship with puck resistance. This article starts from the principles of pressure, analyzes why insufficient puck resistance leads to reduced extraction efficiency, and offers three actionable adjustment directions: grind finer, increase the dose, and increase tamping force. At the same time, combined with the characteristics of beans with different roast levels such as Front Street Classic Blend, Commercial Blend, Huakui SOE, and Natural Red Cherry SOE, it explains how the grind setting should be matched, helping coffee enthusiasts bring espresso extraction back into the normal range.

A friend once asked while buying beans at the Front Street store: can coffee grounds that have already been brewed once be used again for a second cup? Some bloggers online have also demonstrated that a second brew can still yield decent flavor. From a practical standpoint, of course coffee grounds can be brewed again—even a third or fourth time.
