Three popular infusions: coffee, mate and tea

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 (a process often called steeping). 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 (as in a coffeemaker).

History

The first recorded use of essential oils was in the 10th or 11th century by the Persian polymath Avicenna, possibly in The Canon of Medicine .[ citation needed ]

Tea is far older than this, dating back to the 10th century BC as the earliest recorded reference.

Preparation techniques

Infusion is a chemical process that uses botanicals (typically dried herbs, flowers or berries) that are volatile and release their active ingredients readily in water, oil, or alcohol. In this process, a liquid is typically boiled (or brought to another appropriate temperature) and poured over the herb. After the herb has been allowed to steep in the liquid for an appropriate period of time, it is removed (possibly by straining) leaving an infusion. Unless the infusion is to be consumed immediately, it is bottled and refrigerated for future use.

The amount of time the herbs are left in the liquid depends on the kind of infusion. Infusion times can range from seconds (for some kinds of Chinese tea) to hours, days, or months (for liqueurs like sloe gin).

There are several accessories and techniques for removing the steeped or leftover botanicals that were used to infuse liquids, including metal steepers (which look like clamps), tea infusers (which act as strainers), and french presses (which are commonly used to infuse water with various teas and coffee). The most commonly used technique is the teabag, which is made with filter paper and filled with various tea flavors.

A drink or beverage is a liquid intended for human consumption. In addition to their basic function of satisfying thirst, drinks play important roles in human culture. Common types of drinks include plain drinking water, milk, juice, smoothies and soft drinks. Traditionally warm beverages include coffee, tea, and hot chocolate. Caffeinated drinks that contain the stimulant caffeine have a long history.

<span class="mw-page-title-main">Herbal tea</span> Beverage made from infusing or decocting plant material in hot water

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. Many herbs are used in herbal medicine. Some herbal blends contain actual tea.

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.

<span class="mw-page-title-main">Cannabis tea</span> Cannabis-infused drink

Cannabis tea is a cannabis-infused drink prepared by steeping various parts of the cannabis plant in hot or cold water. Cannabis tea is commonly recognized as an alternative form of preparation and consumption of the cannabis plant, more popularly known as marijuana, pot, or weed. This plant has long been recognized as an herbal medicine employed by health professionals worldwide to ease symptoms of disease, as well as a psychoactive drug used recreationally and in spiritual traditions. Though less commonly practiced than popular methods like smoking or consuming edibles, drinking cannabis tea can produce comparable physical and mental therapeutic effects. Such effects are largely attributed to the THC and CBD content of the tea, levels of which are drastically dependent on individual preparation techniques involving volume, amount of cannabis, and boiling time. Also in common with these administration forms of cannabis is the heating component performed before usage. Due to the rather uncommon nature of this particular practice of cannabis consumption in modern times as well as the legality of cannabis throughout the World, the research available on the composition of cannabis tea is limited and based broadly around what is known of cannabis as it exists botanically.

<span class="mw-page-title-main">Tea blending and additives</span> Blending different teas together

Tea blending is the act of blending different teas together to produce a final product that differs in flavor from the original tea used. This occurs chiefly with black tea, which is blended to make most tea bags, but it can also occur with such teas as Pu-erh, where leaves are blended from different regions before being compressed. The most prominent type of tea blending is commercial tea blending, which is used to ensure consistency of a batch on a mass scale so that any variations between different batches and seasons of tea production do not affect the final product. However, it is also common to blend tea leaves with herbs and spice, either for health purposes or to add interesting and more complex flavor notes. It is important that any one blend must taste the same as the previous one, so a consumer will not be able to detect a difference in flavor from one purchase to the next.

<span class="mw-page-title-main">Extract</span> Category of substance

An extract (essence) is a substance made by extracting a part of a raw material, often by using a solvent such as ethanol, oil or water. Extracts may be sold as tinctures, absolutes or in powder form.

<span class="mw-page-title-main">Fragrance extraction</span> Separation process of aromatic compounds from raw materials

Fragrance extraction refers to the separation process of aromatic compounds from raw materials, using methods such as distillation, solvent extraction, expression, sieving, or enfleurage. The results of the extracts are either essential oils, absolutes, concretes, or butters, depending on the amount of waxes in the extracted product.

<span class="mw-page-title-main">Decoction</span> Extraction by boiling herbal or plant material to dissolve the chemicals of the material

Decoction is a method of extraction by boiling herbal or plant material to dissolve the chemicals of the material. It is the most common preparation method in various herbal-medicine systems. Decoction involves first drying the plant material; then mashing, slicing, or cutting the material to allow for maximum dissolution; and finally boiling in water to extract oils, volatile organic compounds and other various chemical substances. Occasionally, aqueous ethanol or glycerol may be used instead of water. Decoction can be used to make tisanes, tinctures and similar solutions. Decoctions and infusions may produce liquids with differing chemical properties, as the temperature or preparation difference may result in more oil-soluble chemicals in decoctions versus infusions. The process can also be applied to meats and vegetables to prepare bouillon or stock, though the term is typically only used to describe boiled plant extracts, usually for medicinal or scientific purposes.
