Can Underextracted Pour-Over Coffee Be Rebrewed? A Detailed Explanation of the Four Key Parameters Affecting Flavor
An under-extracted pour-over coffee often has low concentration and bland flavor, leaving people unsure how to fix it. Over-extraction can still be solved by adding water to dilute it, but under-extraction is tricky. Front Street Coffee started from an interesting experiment and actually tested whether pouring some of the brewed coffee back onto the coffee bed for re-extraction is feasible. This article not only verifies the practical effect of this method, but also deeply analyzes the key influence of the four major extraction parameters—water temperature, grind size, ratio, and time—on flavor, helping coffee enthusiasts find a feasible corrective approach when brewing goes wrong, while also reminding everyone: rather than fixing it afterward, it is better to brew it right from the start.

Can Espresso Be Extracted Twice After an Interrupted Shot? Testing the Impact of Split Extraction on Flavor and Strength
If you mistakenly press the stop button during espresso extraction before reaching the target yield, can you simply press it again to continue extraction? This article compares three espressos—normal extraction, mid-extraction stop-start, and stop-start near the final phase—to analyze how segmented extraction affects the color, flavor, and concentration of the coffee liquid. Front Street Coffee uses the Warm Sun blend, testing with 20g of grounds extracted to 40ml at a 1:2 brew ratio, to reveal why under pressurized extraction, changes in the puck structure cause an overly fast flow rate and under-extraction during a second extraction, along with operational recommendations.

Can Drip Bag Coffee Be Reused for Multiple Brews? Analyzing the Fundamental Differences Between Coffee and Tea Through the Dissolution Characteristics of Chlorogenic Acid
Drip bag coffee, with its convenience and high cost-performance ratio, is attracting more and more people with no coffee-making experience to give it a try. Front Street Coffee's Fruit Dding Ding, Huakui, and Yirgacheffe suit those who prefer floral and acidic notes, while Mandheling, Huilan, and Blue Mountain are better suited to those who pursue a rich, full-bodied taste. However, beginners often run into all kinds of questions in practice, and one frequently mentioned topic is: how many times can a single drip bag actually be brewed? This article will focus on the release patterns of coffee solubles, with emphasis on explaining the role chlorogenic acid plays in extraction, clarifying why coffee, unlike tea leaves, cannot be brewed repeatedly, and why re-extraction after a normal brew is not recommended, helping enthusiasts build a clearer understanding of extraction.

A Complete Analysis of the Causes of Thin Espresso Crema, Large Bubbles in Crema, and Bland Flavor, and Grind Adjustment
When making espresso, have you ever encountered thin crema, large bubbles floating on the surface, or a weak-tasting shot? The root cause of these problems often points to the same variable—grind size. Grinding too coarse speeds up the flow of hot water and shortens the contact time between water and coffee grounds, which not only under-extracts the flavors but also causes the force of the liquid stream to whip air into the espresso, forming large bubbles. In addition, improper storage of coffee beans leading to the loss of carbon dioxide and aromatic compounds, or switching to beans with a different roast level without recalibrating the grind, can likewise trigger similar symptoms. This article will break down these causes one by one and provide specific grind adjustment methods and formulas to help you once again extract espresso with rich crema and full-bodied flavor. [more…]
An Analysis of the Seven Major Pour-Over Coffee Schools: A Full Comparison of Brewing Techniques Including the One-Pour and Three-Pour Methods
The charm of pour-over coffee lies not only in the flavor itself, but also in the ever-changing brewing techniques.

Is it OK to pause and resume an espresso shot mid-extraction? Testing how different resume points affect concentration and flavor
When pulling espresso, you occasionally get distracted and stop before the liquid weight reaches the target. Can you press the brew button again to make up the missing amount? Front Street ran a set of controlled experiments using its own Front Street Strawberry Candy · Espresso: first, a normal espresso was made, then extraction was cut off at one-half, two-thirds, and four-fifths of the target liquid weight and restarted, and a refractometer was used to measure and compare the flavors. The results showed that the earlier the extraction was cut off, the greater the gap in concentration and extraction yield, and the thinner the mouthfeel. The reason is related to changes in puck resistance under pressurized extraction. If you have also encountered the situation of cutting off and then topping up the shot, this hands-on test can give you clear operating advice. [more…]
