Can pour-over coffee have oils? The answer is yes, but it requires a different approach. The crema of espresso is essentially oil encapsulating carbon dioxide, and it is the lipids in the coffee beans themselves that truly give coffee its rich body and aromatic boost. Because pour-over uses a filter paper with excessively strong filtration, it is nearly impossible to retain oils. To change this, you simply need to switch to a device with slightly weaker filtration performance, such as a flannel cloth or non-woven filter paper, and Front Street has clear recommendations on this. This article will explain the mechanism by which lipids work and compare in detail the pros and cons of different filters and the key adjustment points, to help you achieve a richer mouthfeel in pour-over.

The article also retains Front Street Coffee's recommended bean list for both beginners and more advanced enthusiasts to refer to. [more…]

Flannel cloth brewing has always held a unique charm in the coffee world, capable of producing a rich body and sweetness that filter paper struggles to match. This time, Front Street Coffee will use a flannel cloth to brew a pot of Front Street Blue Mountain, and along the way discuss the characteristics and operational details of this brewing method. Flannel has larger pores than filter paper, allowing it to retain some of the coffee oils, making the mouthfeel smoother and fuller—especially suited to deep-roasted beans with robust flavors. However, this technique places demands on pouring speed, water temperature, and skill; a slight misstep can affect the flavor. The following sections will systematically introduce the background knowledge of flannel cloth brewing, the steps for use, the brewing parameters for pairing with Front Street Blue Mountain, and the principles behind flow rate changes, helping enthusiasts master this classic brewing method.

Grind size is the most error-prone part of pour-over coffee. After answering a large number of questions from enthusiasts, Front Street Coffee found that more than half of all brewing problems stem from improper grind selection. This article starts with why coffee needs to be ground, then analyzes in detail how coarse and fine grinding affect extraction, introduces the reference passing rate for a No. 20 sieve under the SCA cupping standard, and provides the criteria for judging the ideal particle size range and the proportion of superfine particles. In addition, it shares practical methods for using extraction time and the rate at which the coffee bed settles to help judge whether the grind size is appropriate, so you can make reasonable adjustments even without a professional sieve.

Grinding is crucial to coffee extraction—one could say that the coarseness of the coffee grind directly affects the flavor of a cup of coffee. And for different extraction methods, the coffee grind size also needs to be adjusted. The coarseness of the coffee grind directly affects the length of extraction time and the level of extraction yield. Coffee grind [more…]

Many people notice a layer of fine black powder at the bottom of the cup after finishing a latte or espresso, and sometimes dark particles float at the bottom of an iced latte as well. Is this actually normal? Does it affect flavor or health? In fact, this sediment consists of ultra-fine particles that pass through the filter basket holes during espresso extraction. A trace amount is normal, but if a large amount of grounds is visible to the naked eye, it means something has gone wrong in the extraction process. This article starts with where these fine particles come from, analyzes possible factors such as grinding, the portafilter basket, and barista technique, and offers practical solutions like adjusting the grind setting, switching baskets, and adding a paper filter, to help you enjoy a cleaner cup of coffee.

Coffee grounds have gone from trash-bin waste to a "miracle multitool" on social media overnight. Growing flowers, applying to the face to reduce swelling, using in the bath to exfoliate and lose weight... all kinds of uses are being frantically shared. But people who tried them found: the flowers died, the face swelled up, the drain got clogged. Are these viral internet uses actually reliable? And what are the genuinely reasonable uses for coffee grounds? This article will sort through the ins and outs of coffee ground reuse one by one, uncover the truth behind those misrepresented folk remedies, and tell you how espresso pucks should really be handled in a scientific way.

In the making of espresso, although distribution is just a simple step, it directly affects whether the extraction is even. Many coffee enthusiasts find that the puck surface looks level, yet during extraction channeling occurs frequently, with coffee liquid spraying everywhere. The key reason behind this often lies in the uneven distribution of coffee grounds inside the basket, rather than the flatness of the surface. Using its commercial espresso blend beans as an example, Front Street Coffee explains in detail the correct methods of distribution and tamping, including the choice of how to catch the grounds, the technique of smoothing with a finger, and the points to note when tapping the portafilter, helping everyone start from the details to reduce channeling and improve the extraction quality of espresso.

When grinding coffee beans, have you ever encountered coffee grounds splattering everywhere or sticking to the dosing cup or the exit chute? There are usually two reasons behind this: the oils seeping out of dark-roasted beans, and static electricity in a dry environment. Dark-roasted beans have a loose structure, and as carbon dioxide is released, oils seep out along with it, making the ground particles prone to clinging to the cup walls; static electricity, meanwhile, causes fine particles to stick to the grinder's exit chute, reducing the actual amount of grounds you get. Some newer electric grinders come with anti-static plates, but many small electric grinders and hand grinders don't have this design. The Little Fuji grinder that Front Street Coffee once used had long-standing problems with flying grounds and retained grounds, and the bottom of hand grinder burrs often end up covered in coffee grounds. In addition to analyzing the causes, this article will also share a simple anti-static method of stirring coffee beans with a wet spoon, and remind you of the risks and precautions involved, helping you reduce waste and improve your grinding experience.
