Tricetinidin is an intense red-colored chemical compound belonging to the 3-deoxyanthocyanidins. It can be found in black tea infusions. [1] Tricetinidin, in tea, would be a product of the oxidative degallation of epigallocatechin gallate (EGCG). [2]
Herbal teas, also known as herbal infusions and less commonly called tisanes, are beverages made from the infusion or decoction of herbs, spices, or other plant material in hot water. Oftentimes herb tea, or the plain term tea is used as a reference to all sorts of herbal teas. Some herbal blends contain actual tea.
A teapot is a vessel used for steeping tea leaves or a herbal mix in boiling or near-boiling water, and for serving the resulting infusion which is called tea. It is one of the core components of teaware. Dry tea is available either in tea bags or as loose tea, in which case a tea infuser or tea strainer may be of some assistance, either to hold the leaves as they steep or to catch the leaves inside the teapot when the tea is poured. Teapots usually have an opening with a lid at their top, where the dry tea and hot water are added, a handle for holding by hand and a spout through which the tea is served. Some teapots have a strainer built-in on the inner edge of the spout. A small air hole in the lid is often created to stop the spout from dripping and splashing when tea is poured. In modern times, a thermally insulating cover called a tea cosy may be used to enhance the steeping process or to prevent the contents of the teapot from cooling too rapidly.
Lapsang souchong is a black tea consisting of Camellia sinensis leaves that are smoke-dried over a pinewood fire. This smoking is accomplished either as a cold smoke of the raw leaves as they are processed or as a hot smoke of previously processed leaves. The intensity of the smoke aroma can be varied by locating the leaves closer or farther from the source of heat and smoke or by adjusting the duration of the process. The flavour and aroma of lapsang souchong is described as containing empyreumatic notes, including wood smoke, pine resin, smoked paprika, and dried longan; it may be mixed with milk but is not bitter and usually not sweetened with sugar. The tea originates from the Wuyi Mountains region of Fujian, China and is considered a Wuyi tea. It is also produced in Taiwan (Formosa). It has been labelled as smoked tea, Zheng Shan Xiao Zhong, smoky souchong, tarry lapsang souchong, and lapsang souchong crocodile. While the tea leaf grading system adopted the term souchong to refer to a particular leaf position, lapsang souchong may be made with any leaf of the Camellia sinensis plant, though it is not unusual for the lower leaves, which are larger and less flavourful, to be used as the smoking compensates for the lower flavour profile and the higher leaves are more valuable for use in unflavoured or unblended teas. In addition to its consumption as a tea, lapsang souchong is also used in stock for soups, stews and sauces or otherwise as a spice or seasoning.
Although health benefits have been assumed throughout the history of using Camellia sinensis as a common beverage, there is no high-quality evidence that consuming tea confers significant benefits other than possibly increasing alertness, an effect caused by caffeine in the tea leaves. In clinical research conducted over the early 21st century, tea has been studied extensively for its potential to lower the risk of human diseases, but there is no good scientific evidence to indicate that consuming tea affects any disease or improves health.
Maghrebi mint tea, also known as Moroccan mint tea is a North African green tea prepared with spearmint leaves and sugar.
Steeping is the soaking of an organic solid, such as leaves, in a liquid to extract flavours or to soften it. The specific process of teas being prepared for drinking by leaving the leaves in heated water to release the flavour and nutrients is known as steeping. Herbal teas may be prepared by decoction, infusion, or maceration. Some solids are soaked to remove an ingredient, such as salt, where the solute is not the desired product.

Dianhong tea is a type of relatively high-end, gourmet Chinese black tea sometimes used in various tea blends and grown in Yunnan Province, China. The main difference between Dianhong and other Chinese black teas is the amount of fine leaf buds, or "golden tips," present in the dried tea. Dianhong tea produces a brew that is brassy golden orange in colour with a sweet, gentle aroma and no astringency. Cheaper varieties of Dianhong produce a darker brownish brew that can be very bitter.

Infusion is the process of extracting chemical compounds or flavors from plant material in a solvent such as water, oil or alcohol, by allowing the material to remain suspended in the solvent over time. An infusion is also the name for the resultant liquid. The process of infusion is distinct from both decoction—a method of extraction involving boiling the plant material—and percolation, in which water is passed through the material.

Brazilian tea culture has its origins in the infused beverages, or chás, made by the indigenous cultures of the Amazon region and the Rio da Prata basin. It has evolved since the Portuguese colonial period to include imported varieties and tea-drinking customs.
