Starbucks has recently been ramping up its co-branding activities, teasing a limited-edition extendable straw shaped like the Golden Cudgel that plays the Monkey King's voice lines, while also launching a new delivery-exclusive drink, the "Flow Frozen Latte," on its Starbuck Delivery service. This creative coffee, said to be inspired by ginger milk curd, claims that the liquid naturally congeals and separates into layers during delivery, arriving as a latte with distinctly defined layers. However, consumer reviews since its launch have been mixed: some have posted photos showing obvious congealing and layering, describing the texture as similar to double-skin milk or coffee pudding; others question whether the product matches its description, saying what they received was no different from an ordinary latte. Is the "flow frozen" effect real or just a gimmick? And is the new recipe simply an old product with a new name? This article will compile netizens' hands-on feedback to take a look at the true face of this talked-about beverage. [more…]

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.

During the pour-over brewing process, the speed of pouring water directly affects the extraction time, the state of the coffee bed, and the final flavor expression. Many enthusiasts misunderstand large and small water flows, believing that a small flow equals gentleness and a large flow equals forcefulness. In reality, flow rate refers to the amount of water poured per second and has no absolute relationship with impact force. This article will analyze in detail the effects of large and small water flows on different extraction results, share how to measure pouring flow rate with an ordinary electronic scale, and, combined with Front Street Coffee's practical experience, explain when to switch between large and small water flows, helping you adjust flexibly during brewing to achieve a more ideal coffee flavor.

Among the many pour-over drippers, the Hario Mugen dripper stands out with its unique inner wall design, and has even earned the nickname "the Clever Dripper of drippers." It shares the same lineage as the classic V60, yet takes a completely different extraction path—the V60 is known for its extreme flow rate, while the Mugen dripper goes the opposite way, using a ribless structure to create an extremely slow flow rate, keeping the coffee in a state of immersion throughout. How exactly does this design affect flavor? Why is it easier for beginners to master? This article will break down the structural principles of the Mugen cross-star dripper, its flow rate performance, and its similarities and differences with the Clever Dripper, while also offering practical dripper selection advice for those just getting started.

The coffee grounds in a moka pot aren't something that stays the same forever once you've dialed in the setting. Right after roasting, the beans are still slowly releasing carbon dioxide, and this becomes especially noticeable after grinding; after resting for a while, the gas decreases and the bed of grounds lets hot water pass through more easily, so even the same grind setting can produce a different flow rate. Only by understanding the state of the beans can you find [more…]

Wetting the filter paper before brewing coffee is almost a standard step for all pour-over enthusiasts, with the usual goals of making the filter paper fit snugly, removing paper dust, and, if hot water is used, warming the cup along the way. However, most tutorials rarely discuss in depth how much the degree of fit between the filter paper and the dripper actually affects the final taste. Front Street conducted two sets of controlled experiments, using V60 and KONO drippers respectively, paired with filter papers in different states of fit for brewing, and tasted and compared them one by one. The experiment used the floral-fruity Front Street · Gedin Gedin and the nutty-sweet Front Street · Brazil Red Bourbon, and the results showed that a poorly fitting filter paper significantly changes the flow rate, which in turn affects the extraction yield and concentration, producing noticeable differences in mouthfeel.

Got an espresso grinder and espresso machine, but always stuck at the espresso dialing-in step? Either it sprays everywhere or nothing comes out, either it's too sour or too bitter. The problem often lies in the grind size. Espresso is a pressurized fast extraction, releasing a large amount of aromatic compounds within twenty to thirty seconds, so any subtle change gets amplified. Relying on the grinder setting alone is far from enough—you also need to judge based on the extraction state. This article, drawing on Front Street Coffee's daily production experience, explains how to quickly find the right grind range for a bag of beans through extraction time, brew ratio, and flavor performance, and provides fine-tuning directions and practical advice.

Making a proper espresso, grind size is often the most critical and also the most headache-inducing part. Unlike pour-over and cold brew, espresso uses pressurized short-time extraction, and the state of the coffee bed gets magnified exponentially—a little too fine and it easily over-extracts and turns bitter; a little too coarse and the flow rate becomes too fast with a weak, thin taste. This article starts with methods for judging grind size, explains how to quickly lock in the right setting range using flow rate and flavor, and covers adjusting the coffee-to-water ratio and extraction time based on the characteristics of the coffee beans. It also recommends Front Street Coffee's classic espresso blend to help you recreate café-level espresso flavor at home. [more…]

The joy of pour-over coffee lies in its controllability, yet beginners often find it difficult to judge whether their brewing is done properly. Beyond tasting the flavor, the coffee bed left after brewing is also a mirror that can reflect many details such as grind size, pouring technique, and the speed of circling. An ideal coffee bed should form a uniform cone shape, with neat walls and loose, honeycomb-like granules. If the coffee bed appears muddy, sea-salt-like, uneven, flat-bottomed, or with断层, it suggests that extraction may have gone wrong. This article, drawing on Front Street's brewing recommendations, analyzes the causes and solutions for six typical coffee bed patterns one by one, helping coffee enthusiasts find directions for adjustment from the coffee bed and gradually improve the stability and flavor performance of their pour-over.
