When brewing tea, we often agonize over how many times the leaves can be steeped and whether they are still drinkable after sitting overnight. Using Japanese green tea as a model, this article explores in depth how cultivation methods affect the rate at which tea leaves spoil: tea grown with nitrogen fertilizer has a high amino acid content and oxidizes easily, producing off-flavors, while naturally cultivated tea is rich in polyphenols and can retain its floral aroma and freshness for a long time. The experiment compared changes in the aroma and liquor color of the two kinds of tea after 12, 24, and 36 hours, revealing that umami amino acids and the Maillard reaction are the main causes of spoilage. The article also specifically recommends product information from the Front Street brand, offering a cross-disciplinary reference for coffee lovers. Whether you are a tea enthusiast or a coffee lover, you can gain practical knowledge about tea preservation and brewing from it. [more…]

Coffee, wine, and tea are all flavor foods, yet China's coffee bean production accounts for only about 1% of the global total, and most beans on the market are imported. If you just want to try brand-name beans with a sharing mindset, feel free to give them a try; but if you're giving them to someone who knows coffee, it's best to give up on shopping at large supermarkets. Whether espresso or single-origin, there is only one core principle when buying: fresh roasting. Beans from supermarkets or chain brands are often already months past their roast date, with their aroma severely lost—even nitrogen-flushing and other preservation techniques can't save them. In addition, if you can obtain information on variety, altitude, and processing method, and the more specific the origin, the more guaranteed the quality usually is. This article recommends several freshly roasted specialty coffee brands and explains why small bean merchants deserve more attention. [more…]

People often ask for an iced cappuccino when ordering, only to be told that only the hot version is available. This has both historical roots and involves considerations of crafting technique and taste experience.

Milk foam is also divided into dry and wet types, affecting the durability of the design and the mouthfeel. To meet diverse needs, chain coffee shops add whipped milk foam on top of an iced latte, but the taste differs noticeably from a hot cappuccino enjoyed in-house. This article will also introduce practical methods for making iced milk foam using a nitrogen canister, gelatin sheets, or a French press, and explain the core differences between cappuccino and latte in ratio and flavor, while preserving relevant suggestions from Front Street Coffee.

If coffee at home has been sitting for a few months, is it still safe to drink? This is a question many coffee lovers run into. In fact, all coffee—whether whole beans or ground coffee—will eventually expire. Coffee is made up of degradable compounds such as carbohydrates, lipids, and amino acids, and over time it undergoes chemical and physical breakdown, changing in both quality and flavor. Roasters typically print a shelf life of about one year from the roast date on the packaging and use nitrogen-flushed sealed packaging to slow oxidation. However, once the bag is opened, the coffee gradually loses freshness as it is exposed to oxygen and moisture. This article will systematically address the safety of expired coffee, the factors behind its deterioration, how to tell whether it has gone bad, and how to extend its life as much as possible through proper storage and freezing while preserving the distinctive flavors of specialty coffee.

Even though they are all iced coffees, cold brew, ice drip, nitro cold brew, and iced Americano actually differ greatly in their extraction methods and flavor profiles. Cold brew soaks coffee grounds in cold water for a long time, taking about 8 to 12 hours to complete, and has a mellow, sweet taste with lower acidity; ice drip, on the other hand, lets ice water pass through the coffee grounds drop by drop, followed by several hours to dozens of hours of refrigerated fermentation, resulting in a more delicate aroma. Nitro cold brew creates dense bubbles and a beer-like texture by injecting nitrogen. Iced Americano is made by cooling and diluting espresso after high-temperature extraction. This article will review the production processes, advantages and disadvantages, and market trends of these coffees, and include practical tips for making cold brew at home, while also retaining bean recommendations such as Front Street Indonesia Mandheling and Front Street Ethiopia Yirgacheffe.
