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…]

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.

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.
