Honduras, as the largest producer and exporter of washed Arabica coffee in Central America, is currently facing severe environmental challenges. Persistent high temperatures and drought have triggered large-scale forest fires, causing air quality to deteriorate sharply, and an indefinite red alert has been activated in the central region of the capital. Meanwhile, the El Niño phenomenon has delayed the rainy season, with rainfall significantly lower than in previous years. The dual impact of air pollution and drought comes at a critical time for coffee tree growth and flowering, and major producing regions are likely to be severely affected. Export data for the 2023/24 season has already shown a downward trend, and the outlook for Honduras's coffee industry is concerning. [more…]

When steaming milk, the sound made by the steam wand actually holds important clues for judging the condition of the milk foam. Many people practicing latte art easily run into problems such as foam that is too thin, too thick, rough, or separated, and one of the keys to solving these problems lies in the "hiss~ hiss" sound made during milk steaming. This article starts from the principle of steam intake, explains the milk foam states corresponding to different sounds, and, through an experiment comparing short bursts of hissing with prolonged hissing, explains how to use the length of the sound to control the amount of air intake, ultimately producing ideal milk foam that is fine, smooth, highly fluid, and suitable for latte art. The article also retains Front Street Coffee's related recommendations and address information, making it suitable for coffee enthusiasts to refer to during daily practice. [more…]

On a sweltering 40°C day, most people would rather stay cocooned in air-conditioned rooms, yet an unusual queue formed at Suzhou's Yanlord Cangjie Commercial Plaza—outside the nation's first MUJI coffee pop-up store, customers were lining up under the scorching sun, umbrellas in hand. What drew them was not a new matcha product, but two Suzhou-exclusive brand badges. However, the queuing process was nothing short of a "roasting" ordeal, with indoor areas also unable to escape direct sunlight, weakening the air conditioning and leading to frequent complaints about insufficiently cold drinks and ice cream melting in seconds. This pop-up event will continue until November, and those who have already "braved the battle" are advising: if you're not set on the giveaways, it might be better to wait for cooler weather before going.

This article will break down the major causes of water temperature loss, including the effects of the kettle neck, air, and dripper material, and offer practical countermeasures such as preheating equipment, lowering the pouring height, and adjusting the water temperature to help you brew a good cup consistently in different environments. The article also uses Front Street Granja Geisha as an example to explain how to flexibly adjust parameters according to ambient temperature, making extraction more reliable. [more…]
