Coffee and tea are both beverages that rely on water to dissolve flavor, so if tea leaves can be steeped repeatedly, can coffee grounds do the same? In terms of composition, about thirty percent of coffee beans is soluble matter, which theoretically does support multiple extractions. In practice, however, the coffee liquid obtained from repeated brewing tends to be thin and carry off-flavors. The reason is that a normal extraction has already released most of the sweet and sour essence, and the remaining substances cannot support good flavor. This article will start from extraction yield and the order in which flavors dissolve to explain why coffee grounds are single-use, and to clarify why pour-over and drip-bag coffee are not recommended for repeated brewing.

When brewing coffee, most people focus on whether the water's TDS is in the appropriate range, but few pay attention to whether repeatedly boiling the hot water affects the coffee's flavor. Some believe that coffee brewed with water that has been boiled multiple times will decline in quality. To verify this claim, Front Street Coffee designed a controlled experiment, using a TDS test pen and a coffee concentration meter, brewing a medium-light roasted Sidamo Hachira 8.0 by immersion in a clever cup, using water boiled for the first through fourth times respectively, and recording the TDS value of the water and the coffee concentration performance each time. This article will present the experimental setup, operating procedure, and data results one by one, to help coffee enthusiasts determine whether repeatedly boiled water is truly unsuitable for brewing coffee.

Many people only have drip bags on hand but want to drink a latte with a milky aroma—is this actually possible? The black coffee brewed from a drip bag is far less concentrated than espresso, and adding milk directly tends to make it weak and separated. But drip bags originate from pour-over, which is highly versatile; as long as you find a way to increase the concentration of the coffee liquid, you can make a decent-tasting "fake latte." This article compiles four practical methods summarized by Front Street Coffee: the stirring method, the repeated brewing method, the milk brewing method, and the added milk powder method, and recommends medium-to-dark roast beans suitable for pairing with milk, such as Indonesian Mandheling, Colombian Huila, Queen's Estate, Cerrado, and Blue Mountain No. 1. Whether at home, in the office, or camping, you can achieve a rich and smooth milk coffee experience with simple steps. [more…]

I believe baristas must have encountered this problem: in the morning, the espresso extraction parameters are dialed in, but by noon, the parameters are no longer accurate, and the coffee flow rate has noticeably slowed down. Front Street has previously offered explanations for two scenarios regarding this issue. The first is when it rains and the humidity in the air is relatively high, inside the bean hopper. [more…]

Fermentation is a core step in coffee processing that shapes flavor direction. It is driven by microorganisms such as yeasts and bacteria, which convert sugars and acids within the coffee cherry into acids and alcohols. Good, controlled fermentation can highlight a coffee's varietal characteristics, while uncontrolled fermentation may bring negative flavors reminiscent of spoilage and spoiled wine. Starting from the basic principles of fermentation, this article sorts out the differences between the two pathways—aerobic and anaerobic—and, around six major factors—coffee cherry quality, cleanliness, oxygen, microorganism and yeast types, time and temperature, and data recording—explains how to improve the consistency and repeatability of fermentation. It also emphasizes that coffee quality is largely fixed during the growth stage, and the role of fermentation is to extract and preserve excellent characteristics rather than to elevate quality out of thin air. The article also introduces Front Street Coffee's ongoing attention to knowledge related to fermentation and processing methods, for the reference of coffee enthusiasts. [more…]

A friend once asked while buying beans at the Front Street store: can coffee grounds that have already been brewed once be used again for a second cup? Some bloggers online have also demonstrated that a second brew can still yield decent flavor. From a practical standpoint, of course coffee grounds can be brewed again—even a third or fourth time. But "can be brewed" and "tastes good" are two entirely different matters. This article starts from actual tests on Front Street's Sidra, and combines the proportion of soluble matter, extraction yield control, and the differences in dissolution rates of acidity, sweetness, and bitterness to explain why coffee is usually brewed only once, and the fundamental reasons why a second brew tastes thin and lacks layering, before offering a conclusion that better suits the general palate. [more…]

Many coffee enthusiasts, when making espresso, often overlook a step that seasoned baristas repeatedly emphasize—letting hot water run for a few seconds before extraction. This seemingly simple action actually has a significant impact on the final flavor of the coffee. This article will explain the necessity of pre-flushing from two perspectives: brew head cleanliness and extraction stability, and through a comparative experiment at Front Street, demonstrate the specific differences that flushing versus not flushing makes on espresso taste and extraction yield. At the same time, we will also analyze why coffee machines that have been unused for a long time tend to cause extraction deviations, helping you more precisely control the quality of every cup of espresso in your daily routine.

The volcanic pour is a highly distinctive brewing method within the Japanese hand-brewing system, named for the way the coffee bed rises and bubbles like a volcanic eruption during extraction. It is designed specifically for dark-roasted coffee, relying on a small stream of water, multiple intermittent pours of small volumes, and a high-concentration, low-extraction approach to ultimately present a cup of coffee with pronounced sweetness and a rich, smooth body. Starting from Front Street's experience shared on multiple occasions, this article provides an in-depth analysis of the underlying logic of the volcanic pour: why it can create a volcanic eruption-like spectacle, why only dark-roasted beans are up to the task, and how high concentration with low extraction avoids bitterness and improves extraction efficiency. The article also provides complete brewing parameters and a practical demonstration using Front Street's Golden Mandheling, guiding you step by step through this brewing experience that is both visual and gustatory.【图片1】【图片2】【图片3】【图片4】【图片5】【图片6】【图片7】【图片8】【图片9】【图片10】【图片11】 [more…]
