When selecting coffee beans, start by considering your daily drinking scenarios: is it a cup of black coffee in the early morning, or a milk coffee to go with breakfast; is it a slow pour-over to savor, or a quick cup from a machine. Different scenarios call for different roast levels, flavor intensity, and brewing methods. The moka pot is a steam-pressure extraction device, [more…]

The roast level determines which way the flavor leans: light roasts have distinct floral and fruity notes with bright acidity, medium roasts offer a pleasant sweetness and balance, and dark roasts are steady with nutty, cocoa notes and a full body, while the extraction rhythm also changes. There is no superior or inferior option—just match it to your brewing method. A moka pot uses steam pressure to complete extraction; simply fill the basket. [more…]

Starbucks has once again teamed up with Mayday to launch a co-branded campaign, rolling out a Bergamot Grapefruit Sparkling Americano and themed limited-edition cups printed with classic Mayday lyrics. It should have been a grand occasion for fans to celebrate. However, after the campaign kicked off, many consumers took to social media to air their complaints: the drink labels happened to be stuck right over the lyric designs, and the residue was hard to remove after peeling them off; those who bought multiple cups in one go received the same design, dashing their collection plans. The brand and store staff have responded with explanations, saying the labels should be placed in the notes section, while the identical cups were due to stores needing to use up inventory in sequence. Is this collaboration full of sincerity or a failure in the details? Front Street Coffee walks you through the whole story. [more…]

With its positioning as affordable specialty coffee, Manner Coffee has surpassed a thousand stores nationwide while also attracting a large number of "coffee-brained" office workers who bring their own cups.

Some question whether baristas "deliberately" attach the labels, while others believe it is an oversight during peak hours, and some stores use easy-peel stickers as a base layer. This small controversy over labels reflects consumers' attention to baristas' attention to detail in service. For coffee enthusiasts pursuing quality, a good cup of coffee is not only about taste, but also about the warmth and care in the experience. [more…]

The subsidy war among food delivery platforms continues to heat up, with large-value coupons frequently being thrust at consumers, and the pressure on in-store production has surged accordingly. Recently, Meituan released a batch of delivery coupons for Heytea that can be expanded to "18-18," meaning a drink priced at over twenty yuan costs only a few yuan after the discount, and can even be made nearly free by stacking red envelopes. As soon as the news came out, netizens rushed to place orders, and Heytea stores in many parts of the country saw orders surge in a short time. Delivery rider capacity could not keep up, and delays, stuck orders, and no one accepting deliveries occurred one after another. Some stores, facing shortages of both materials and staff, could only temporarily close and reopen after all the backlogged drinks had been made. At the same time, frontline employees poured out their daily experiences of order explosions on social platforms, busy from morning to night, with no time even to eat or drink. [more…]

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.

The answer is actually quite clear—the moka pot and dark-roasted or medium-dark-roasted, full-bodied beans are a match made in heaven. Why is that?

To be honest, Front Street Coffee thinks that coffee filter paper can really be called a very versatile tool. Because it's not just for pour-over coffee—it's also used for iced drip coffee, cold brew coffee, espresso, and some friends even use it when making coffee with a moka pot! And at this point, some friends have raised a question. [more…]

Have you ever suddenly found yourself out of filter paper while brewing coffee at home—does that leave you completely stuck? Actually, that's not the case. Filter paper is indeed indispensable for pour-over and other drip-style extractions, but if you switch to immersion extraction, its role becomes optional. Immersion extraction means fully steeping the coffee grounds in water. The extraction efficiency gradually slows as the water temperature drops and the concentration difference decreases, so over-extraction is less likely, the margin for error is higher, and the mouthfeel is fuller. Even without any filtering tool, as long as you master a few small techniques, you can still brew a clean, grit-free cup of coffee. In this article, Front Street Coffee will use a native variety from Ethiopia's Kafa Forest, relying on just two containers and a spoon, to test the entire process of filter-free immersion extraction, and compare the core differences between immersion and drip methods.

First-time buyers of pour-over coffee beans often find themselves stuck in a dilemma: should I buy something acidic, or something not acidic? In fact, there is no standard answer to this question.
