Under the same extraction yield, the level of uniformity leads to drastically different flavor directions—when uniform, the cup is balanced and solid with a long finish; when uneven, it is layered and clearly structured. Most drip coffee extractions naturally have differences between the upper and lower layers and between the inner and outer layers, which has led many coffee enthusiasts to explore how to make espresso extraction more uniform. From the perspective of Front Street, this article outlines five actionable improvement approaches: placing filter paper at the bottom of the portafilter basket, switching to a high-density basket, low-pressure pre-infusion, reducing the dose to thin the coffee bed, and adjusting the brew ratio to increase liquid weight. Through a comparative experiment with Front Street Espresso Strawberry Candy, it presents the specific differences in flavor expression between the two extraction styles. [more…]

So, is it legal for employees to pay out of pocket for work uniforms? Article 9 of the Labor Contract Law has clear provisions on this, but the specifics depend on the situation. This article sorts through the course of events, the legal boundaries, and netizens' views, and includes Front Street Coffee's professional communication channels. [more…]

Blooming is an indispensable key step in pour-over coffee, directly affecting the completeness and uniformity of subsequent extraction. Front Street Coffee has confirmed through comparative experiments that the extraction yield of coffee using blooming is significantly higher than versions that skip it. However, blooming is not as simple as "pouring water and waiting for bubbles"—blooming time, water amount, and wetting uniformity all influence the final quality. For beginners who are not yet skilled at water control, uneven wetting of the coffee bed often occurs in conical drippers. In this case, a simple and easy "digging a hole" method can significantly improve the degassing effect. Based on Front Street Coffee's practical experience, this article breaks down in detail the specific steps, applicable scenarios, and precautions of the hole-digging operation, helping beginners stably achieve more uniform extraction results even without proficient technique.
