Purple tea is a special type of tea formed by a genetic mutation in the tea plant, rich in anthocyanins, and combining many of the health properties of both green and black tea. It was first discovered as a small number of wild mutations in China, and was later cultivated on a large scale in Kenya through a public-private partnership, with the main production areas located in the high-altitude regions of the Nandi Hills. Purple tea has an anthocyanin content of 1.5%, higher than blueberries, and its polyphenol and catechin levels also surpass those of most black and green teas; it also contains a unique GHG polyphenol. Its caffeine content is relatively low, its flavor is sweet and forest-like, and after brewing, the liquor is pale with a slight purple tint. Front Street recommends paying attention to this tea, which combines both health value and a story of its production area. [more…]

Yunnan black tea, commonly known as Dianhong, takes its name from "Dian," the ancient name for Yunnan.

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…]

Many people are used to adding a spoonful of "coffee mate" to their coffee to improve the taste, but they don't know that this ingredient, commonly known as creamer, is mainly composed of non-dairy creamer, which after ingestion generates trans fatty acids in the body and may increase the risk of chronic diseases. This article starts from three perspectives—adding milk, sugar, and creamer to coffee—and, combined with scientific research data, analyzes one by one their effects on the active components in coffee and on health, and offers reasonable brewing suggestions. Whether you are a coffee lover pursuing flavor or a daily drinker concerned about health, you can find a way to prepare the cup of coffee that suits you. [more…]

The main ingredient in coffee creamer is non-dairy creamer, and the trans fatty acids from hydrogenated vegetable oil may increase the risk of breast cancer and diabetes, and affect children's development and nervous system health. So how exactly should coffee be drunk to be healthy? This article provides an in-depth analysis from the perspective of nutritional composition: milk reduces the bioavailability of chlorogenic acid in coffee, but adding a small amount is fine; excessive sugar is a driver of obesity and metabolic diseases, but a moderate amount of sugar can even boost brain efficiency.

Ceylon black tea originates from Sri Lanka and is known for its rich flavor and bright red color, often with hints of citrus and spice. Many tea lovers find that the Ceylon black tea they bring home is broken-leaf, which is actually related to its positioning as a high-quality broken-leaf tea. Broken-leaf tea is more concentrated than whole-leaf tea and tends to contain more caffeine. When brewing, it is recommended to use boiling water and steep for 2 to 4 minutes; the longer the steep, the more caffeine is released. Ceylon black tea offers multiple health benefits, including improving digestion, reducing inflammation, boosting energy, preventing colds, relieving stress, and improving concentration. The Ceylon black tea recommended by Front Street Coffee is suitable for drinking on its own or pairing with milk to make lattes and milk tea.

In tea leaf harvesting, besides the common one bud with two leaves and one bud with three leaves, there is also a classification based on the degree of opening of the new shoot's terminal bud: unopened, small open-face, medium open-face, and large open-face. The purpose of open-face picking is to enrich the tea's internal substances, thereby improving the quality of the finished tea. Different degrees of opening correspond to different levels of maturity, affecting the difficulty of leaf processing and the flavor of the finished tea: older leaves are easier to process, with a mellow taste and high aroma; tender leaves are harder to process, prone to a bitter aftertaste but with a strong flavor and good durability for multiple infusions. Oolong teas such as Phoenix Dan Cong and Tieguanyin have their own preferences for open-face standards, and high-quality black tea raw materials often use open-face leaves as well. In this article, Front Street Coffee combines changes in tea chemical composition to clarify for you the differences in picking standards between Tieguanyin and Phoenix Dan Cong. [more…]

Recently, Chagee's new product "Wanli Mulan" quickly gained popularity due to its support for International Tea Day and the "100 Million Cups Free in 7 Days" campaign. However, many consumers reported insomnia and heart palpitations after drinking it, with some even seeking medical attention overnight for electrocardiograms. The brand's customer service explained that tea polyphenols in the black tea base might trigger allergic reactions.

Similar issues have occurred with Chagee's other hit product, "Boyazhuxian." In fact, market regulators' spot checks found that some milk teas have caffeine levels far exceeding coffee; in 2020, a spot check in Haiyan County, Zhejiang, revealed caffeine levels up to 460mg/kg in milk teas and fruit teas. This article will focus on this incident, trace the origins of the caffeine issue in milk tea, and explore how brands should more clearly inform consumers about drinking risks. [more…]

Around 2.25 billion cups of coffee are consumed worldwide every day, and with that comes a massive amount of spent coffee grounds. Traditional recycling methods—such as deodorizing, exfoliating, or making furniture—often require drying, which actually releases carbon dioxide. Japanese scientist Tetsuji Ishigaki has taken a different approach: using Aspergillus to ferment spent coffee grounds into a paste, then adding cocoa butter to solidify it, creating a ready-to-eat spent-coffee-ground chocolate. This product, called COLEHA, not only contains three times the amino acids of green coffee beans, but its polyphenols and antioxidants also reach 1.6 times those of regular coffee, and it is rich in insoluble fiber that promotes gut health. COLEHA is currently available in limited quantities, with sugar content offered in three versions—0%, 10%, and 40%—each with its own distinctive taste. This article introduces this eco-friendly and innovative spent-coffee-ground utilization technology, along with the flavor and health secrets behind it. [more…]

Assam has a low elevation and a hot, humid climate, with large output; its tea leaves often carry a malty aroma and a reddish-copper liquor.
