When grinding coffee beans, static electricity often sends fine particles flying and clumping together, not only dirtying the grinder's chute but also disrupting the uniformity of water flow during extraction. To solve this problem, as early as 2005 someone proposed spraying a small amount of water onto the coffee beans, commonly known as RDT (Ross Droplet Technique). Does this method actually have a scientific basis? Will it have a negative impact on grind quality? This article starts from the mechanism by which static electricity is generated, combines it with the latest research, analyzes the actual effectiveness of the water-spraying method, and also points out the risks to watch for during operation, especially the problems that can arise when the amount of water sprayed gets out of control, such as coffee grounds becoming damp, clumping, and even burrs rusting. For friends who like making coffee at home, as well as for Front Street Coffee, which insists on professional output, understanding these details helps in using this technique more rationally.

Among the many supplementary techniques for making coffee, RDT (Ross Droplet Technique) is a method of reducing static electricity and clumping by spraying water onto coffee beans before grinding. Its principle is not complicated: during grinding, coffee beans generate static electricity due to friction and uneven charge distribution, causing fine particles to stick together into clumps, which in turn lowers the extraction yield and induces channeling. RDT can effectively alleviate this problem, but it also has obvious shortcomings—it is only suitable for single dosing, the water amount is difficult to control, and long-term use may damage the burrs. In this article, Front Street Coffee breaks down the ins and outs of RDT, its actual effects, and its operational limitations in detail, and offers a more reliable alternative. [more…]

Cold drip coffee, with its lengthy brewing process and unique layers of flavor, has always been a topic of interest among coffee enthusiasts. Completely different from cold brew, cold drip requires specialized equipment, precise control of the water drip rate, and subsequent fermentation and aging. This article will analyze in detail the standard steps for making cold drip coffee from four dimensions—grind size, drip speed, extraction ratio, and aging time—and answer the common question of "how long does it actually take to make a cup of cold drip?" At the same time, the article also compiles Front Street Coffee's practical experience and parameter recommendations in cold drip production, helping you understand the complete process of this low-temperature drip coffee in a more systematic way.

In pour-over or espresso preparation, baristas often perform actions such as tapping the table or shaking the milk pitcher, and these behaviors actually have clear professional purposes. From the perspective of Front Street, this article explains two common reasons: first, static electricity generated during grinding in dry seasons, which causes fine particles to stick together or cling to the walls, affecting extraction uniformity; second, large bubbles left by mistakes when steaming milk, which need to be eliminated by shaking the pitcher. Regarding the static electricity issue, the article introduces the RDT droplet technique proposed by David Ross, which suppresses static electricity at the source by spraying a very small amount of water before grinding, while also reminding readers about water volume control and alternative methods. Regarding milk foam bubbles, it explains the professional terminology and operational logic of tapping and shaking the milk pitcher, helping coffee enthusiasts understand and optimize their daily output.

Cold brew coffee is made by slowly infusing coffee grounds with ice water and completing the extraction by controlling the drip rate, resulting in a smooth, full-bodied cup with concentrated aroma. Beans of different roast levels bring completely different flavor directions—dark roasts suit those seeking richness and a sweet finish, while light roasts can showcase floral and fruity aromas and layered complexity. This article centers on the characteristics of cold brew coffee, first introducing several Front Street Coffee beans suitable for making cold brew, then using 60g of Front Street Coffee Huakui as an example to explain the standard cold brew process step by step, including grind size, bed preparation, filter paper placement, blooming and wetting, drip rate adjustment, and the key details of refrigerated oxidation after completion, helping coffee lovers reliably recreate a delicious cup of cold brew at home.

The milk foam on the surface of a latte begins to slowly dissipate from the moment it is made, but the rate of dissipation varies enormously between lattes of different quality—some develop large bubbles within two minutes, while others can hold out for over fifteen minutes. Foam stability is governed by three core factors: the quality of the foam itself, the state of the espresso crema, and the degree of integration between the foam and the coffee. In addition, details such as cup temperature and residual water droplets on the cup wall can quietly affect the pace of dissipation. This article breaks down these variables one by one to help you understand how to make a latte with lasting foam and a stable structure. [more…]

Cold brew coffee uses cold water at 5°C, slowly dripping through the coffee grounds over several hours of extraction, yielding a coffee liquid with rich aroma, a round and smooth mouthfeel, full body, and particularly outstanding flavor expression. Its greatest advantage is that it is neither sour nor astringent and does not irritate the stomach, which is thanks to the choice of dark-roasted coffee beans and the entire cold-water extraction process, avoiding the astringent substances released by hot water at high temperatures. This article will provide a complete introduction to the key points of making cold brew coffee, from the principles and characteristics, the use of equipment, precautions, to the specific production process of the Dutch-style drip brewer, helping coffee enthusiasts make the ultimate 100% original-flavor water-drip coffee at home.

Freshly roasted coffee beans contain a large amount of carbon dioxide, and brewing them directly often leads to uneven extraction and imbalanced flavor. To address this, the Japanese developed a series of solutions, among which the Kono-style drip method is considered a classic. It uses water droplets instead of a water stream to pre-wet the coffee grounds, waits for sufficient degassing before switching to a stronger flow for extraction, and finally adjusts the concentration through bypass. In this article, Front Street Coffee will use PWN Golden Mandheling as an example to break down in detail the parameter settings and operating steps of this brewing method, helping you brew a rich, balanced, and delicious cup even with fresh beans.

There are hundreds of coffee brewing devices on the market, yet there is actually no definitive answer as to which coffee device brews the best-tasting coffee, because everyone's taste preferences differ. Even with the same coffee beans, using the same coffee device and the same brewing time, the acidity, bitterness, sweetness, body, strength, and lightness that each person perceives are [more…]

Cold brew coffee is a method of extracting coffee with ice water at low temperatures, completely different from regular pour-over. It originated from the invention of the Dutch on the island of Java in the 17th century, using condensed water pressure to drip through coffee grounds one drop at a time, taking up to 8 hours. Cold brew coffee has a unique flavor and needs to be refrigerated and fermented after extraction, reaching its best state on days 3 to 7, with a complex aroma reminiscent of fermented rice wine. This article explains in detail the steps for making cold brew coffee, key points for fermentation and storage, and shares three cold brew recipes commonly used by Front Street Coffee—dark berry type, light and clean type, and sweet and delicious type—to help you easily make a delicious cold brew suitable for summer.
