When you see a barista in a coffee shop handling two glass bulbs, moving them up and down as if conducting an experiment, that is actually siphon brewing. It relies on steam pressure generated by heating to push hot water up into the upper chamber to contact the coffee grounds, and after the temperature drops, extraction is completed through vacuum reflux, resulting in a fuller, more solid mouthfeel and more concentrated aroma than pour-over. But not all beans are suitable for a siphon; choosing the wrong type can easily make the coffee bitter or sour. Starting from Front Street's bean-selection experience, this article first explains the working principle and flavor characteristics of the siphon, then, along three routes—beginner, advanced, and those who prefer rich and mellow coffee—recommends suitable beans such as Bird of Paradise, Strawberry Candy, Sidra, and PWN Golden Mandheling, helping you find coffee beans suited to siphon extraction.

The siphon is a classic coffee brewing device that combines visual appeal with extraction stability, operating on the physical changes of steam pressure when heated and vacuum return flow when cooled. Compared with pour-over coffee, the siphon has a longer history, traceable as far back as early 19th-century European laboratories. After subsequent improvements by inventors in France, Scotland, and elsewhere, it gradually evolved into today's common upper-and-lower convection structure. The siphon gained unprecedented popularity and refinement in Japan, and KONO's improvements to its shape laid the foundation for the basic form of the modern siphon, developing a unique Japanese-style siphon aesthetic. Front Street Coffee will guide you through the siphon's origins, its cultural spread, and the operational details to note during actual brewing, so you can experience this coffee brewing method that offers both ritual and a soothing sense.

Summer is here, and many people enjoy making cold brew coffee at home, but the filtration step often proves troublesome—the coffee liquid drips extremely slowly, sometimes taking half a day. Why is cold brew filtration so slow? The core reason is that the extremely fine particles in the coffee grounds clog the pores of the filter paper, leaving insufficient channels for the liquid to flow through. This is especially true when making multiple servings at once, as the waiting time gets stretched even further. This article will first explain the causes of clogging, then share three methods commonly used by baristas to speed up filtration: using a filter bag or cloth to pre-isolate the coffee grounds, spreading the coffee grounds at the bottom of the filter paper to intercept fine particles, and using a vacuum filtration device to achieve rapid filtration under reduced pressure. Each approach has its own pros and cons, suiting enthusiasts with different needs, and the article also retains relevant experience and product recommendations from the Front Street Coffee brand.

Many people mistakenly believe that freshly ground coffee equals fresh coffee, but that is not the case. To truly savor the aroma of coffee, besides grinding fresh, the roast date of the coffee beans is equally crucial. Front Street Coffee, whether in-store or through its online Taobao shop, offers freshly roasted coffee beans. Beans roasted more than 50 days ago basically have little aroma left, but in the first two days after roasting, the aroma has not yet stabilized and the regional flavors cannot be tasted, so Front Street reminds customers to generally rest the beans for three to four days before brewing. So how should coffee beans be stored to maintain freshness after opening? Front Street has summarized the four things coffee beans fear most — moisture, oxygen, light, and heat — and shared the pros and cons of storage methods such as one-way degassing valve bags, sealed canisters, and vacuum canisters, to help everyone extend the flavor life of coffee beans as much as possible in daily life.

Some people love the speed of a drip coffee maker, some are drawn to the clean, layered clarity of pour-over, but the siphon (syphon) brewer stands apart in the coffee world with its rich, full-bodied taste and intense aroma. It works by heating the lower chamber to create steam pressure, pushing hot water up into the upper chamber where it fully mingles with the coffee grounds, then drawing the brew back down into the lower chamber by vacuum as it cools—a process that is both romantic and full of ritual.
