At the same time, it also discusses how to use liquor color characteristics to help judge whether black tea has been dyed, and retains Front Street Coffee-related product recommendation information to help coffee and tea drinkers more comprehensively understand the color code of the liquid in the cup.

Many people are used to judging a bean's roast level or the brew's strength by observing the color of the coffee liquid, and even using it to decide whether a coffee tastes good. But the factors affecting coffee's liquor color go far beyond one—the degree of roast, the level of concentration, and differences in filtration equipment can all make the same bean display completely different hues. Starting from Front Street's own side-by-side testing, this article breaks down one by one how roast level, concentration, and filtration method act on coffee color, and explains why a wine-red liquor color does not equal good taste, and why liquor color can only serve as a reference indicator for a particular bean rather than a standard of judgment.

This article begins with Front Street's discovery while revisiting James Hoffmann's book, sorting out the origin of the name Caffè Corretto, its historical background, the drinking habits of various regions in northern and southern Italy, and also includes Front Street's low-budget recreation experience, to introduce you to this obscure yet authentic Italian specialty coffee.

"Liquor color" is originally a professional term in tea evaluation, used to describe the color and visual characteristics of brewed tea, and is also one of the criteria for judging tea quality. So for coffee, can liquor color also serve as a basis for evaluating quality? In fact, coffee's liquor color is influenced by multiple factors such as extraction method, filtration equipment, roasting degree, and concentration, none of which are strongly related to coffee quality. Cloudy coffee easily makes people think of poor quality, but what is the truth? Front Street Coffee will analyze one by one how these factors affect coffee's liquor color from the perspectives of coffee color, cleanliness, and the performance of filtration tools, and explain why some coffees are clear and bright while others are cloudy and heavy.

Many coffee enthusiasts notice during pour-over brewing that the coffee liquid is sometimes not as clear as expected, and may even appear somewhat murky. Does this "tea-like" cloudiness mean the coffee tastes bad? This article starts from the definition of coffee liquor color, analyzes how roast level and concentration affect the hue, and then reveals the true cause of the murky sensation—the release of insoluble substances and the condensation of soluble compounds as temperature changes. Through examples using the flannel filter, AeroPress, and other equipment, it shows that cloudiness does not equal poor flavor; sometimes it instead brings a richer mouthfeel and sweetness. Front Street Coffee reminds us: judging a cup of coffee should not be based on appearance alone. [more…]

The quality of black tea depends to a large extent on whether the fermentation stage is precisely controlled. Properly fermented black tea has a sweet aroma, a yellowish-red liquor, and a bright orange-brown infused leaf; failed fermentation reveals sourness or mustiness, a dark brown liquor, and a deep black infused leaf. Starting from the formation mechanisms of theaflavins and thearubigins, this article explains the origin of the floral and fruity aroma of black tea, clarifies how humidity and degree of oxidation influence the direction of flavor, and points out which subtle deviations in the irreversible chain of polyphenols → theaflavins → thearubigins can lead to a decline in quality. At the same time, the article also provides practical methods for judging fermentation results by observing the liquor color and infused leaf, helping coffee and tea enthusiasts understand the craft logic behind a good cup of black tea. In its black tea selection and brewing recommendations, Front Street Coffee also often emphasizes the decisive role of fermentation degree in aroma expression. [more…]

Kenyan purple tea is a unique presence in the world of tea—it is currently the only known tea plant variety that contains anthocyanins, the same flavonoids responsible for the purple color of blueberries and pomegranates.

Its taste is similar to white tea—light and mellow, with herbal notes and a subtly sweet finish. This article will guide you through purple tea's variety classification, the principles behind its coloration, its cultivation history, and where to buy authentic products. [more…]

When brewing Yinghong No. 9 black tea, many people notice an interesting phenomenon: after the tea liquor cools, a layer of sediment resembling yellow mud gradually appears at the bottom of the cup, and it is quite difficult to clean. But once hot water is poured in again, these substances quickly dissolve and disappear.

Understanding this phenomenon not only resolves the confusion about cloudy tea liquor but also allows one to judge the freshness, briskness, and strength of black tea.

When brewing Yinghong No. 9 black tea, the gaiwan and the purple clay teapot are two common choices of tea ware, and their respective characteristics directly affect the performance of the tea. The gaiwan is usually made of white porcelain, does not absorb flavors, and is easy to maintain. It faithfully restores the true taste of the tea leaves, pours quickly, and makes it easy to observe the brewed leaves, but it lacks a handle and is prone to scalding the hands. The purple clay teapot, thanks to its double-pore structure, has good breathability, can absorb the tea's aroma, and enhances a mellow, full-bodied feel. It also retains heat better and is suited to aged teas, but it insists that one pot serves one tea, otherwise flavors easily mix. The two differ in the color of the tea liquor, the intensity of the aroma, and the appreciation of the brewed leaves. Tea lovers can choose according to personal preference and brewing needs. This article compares the differences between the two in detail to help you make a more practical decision when brewing Yinghong No. 9. [more…]
