When many people drink a cup of coffee that tastes on the bitter side, their first reaction is, "Has this cup been over-extracted?" But bitterness cannot be directly equated with over-extraction. This article focuses on over-extraction, first explaining what it is—according to the Golden Cup theory and Front Street Coffee's daily practice, an extraction yield above 22% is considered over-extraction; then, from a sensory perspective, it outlines the three typical manifestations of over-extracted coffee: burnt bitterness, astringent bitterness, and off-flavors, and analyzes their causes one by one, such as water temperature being too high, grinding being too fine, contact time being too long, stirring being too vigorous, and too many fines. Finally, it offers two practical ways to avoid it: adjusting the brewing parameters and discarding the tail end of the brew, while also addressing the question of whether coffee can be brewed repeatedly, helping coffee lovers judge and improve their brewing results more accurately.

When buying coffee beans, have you ever noticed the roast date on the packaging? This date is not used to judge whether the coffee has expired like ordinary food—roasted coffee beans typically have a shelf life of six months to a year, and what truly matters is when they reach their peak flavor. Freshly roasted beans degas vigorously, and carbon dioxide hinders extraction; leave them too long and the floral and fruity aromas dissipate, leaving only a woody taste. That is why light-roasted single-origin beans and dark-roasted espresso beans each have their own preferred resting periods. This article will walk you through the flavor logic behind the roast date, help you master the optimal drinking window for coffee beans, and show you how Front Street Coffee manages its shipping schedule so that every bag of beans reaches its peak the moment it arrives.

Pour-over coffee and espresso are the two dominant brewing methods in today's specialty coffee world, yet many enthusiasts remain unclear about how they differ. This article compares the two across four dimensions—coffee bean selection, preparation method, beverage volume, and caffeine content—to help readers clarify the core differences between these two brewing systems. In terms of bean types, pour-over typically uses single-origin beans with flexible roast levels; Front Street Coffee's Guodingding, Strawberry Candy, and PWN Golden Mandheling each cater to different flavor preferences.
