Coffee
Coffee is a beverage brewed from roasted, ground coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content, but decaffeinated coffee is also commercially available. There are also various coffee substitutes. Typically served hot, coffee has the highest sales in the world market for hot drinks. Coffee production begins when the seeds from coffee cherries (the '' Coffea'' plant's fruits) are separated to produce unroasted green coffee beans. The "beans" are roasted and then ground into fine particles. Coffee is brewed from the ground roasted beans, which are typically steeped in hot water before being filtered out. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso, French press, caffè latte, or already-brewed canned coffee). Sugar, sugar substitutes, milk, and cream are often added to mask ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of Coffee
The history of coffee dates back centuries, first from its origin in Ethiopia and later in Yemen. It was already known in Mecca in the 15th century. Also, in the 15th century, Zawiya (institution), Sufi Muslim monasteries (khanqahs) in Yemen employed coffee as an aid to concentration during prayers. Coffee later spread to the Levant in the early 16th century; it caused some controversy on whether it was halal in Ottoman Empire, Ottoman and Mamluk Sultanate, Mamluk society. Coffee arrived in Italy in the second half of the 16th century through commercial Mediterranean Sea, Mediterranean trade routes, while Central and Eastern Europeans learned of coffee from the Ottomans. By the mid 17th century, it had reached India and the East Indies. Coffeehouse, Coffee houses were established in Western Europe by the late 17th century, especially in Holland, England, and Germany. One of the earliest cultivations of coffee in the New World was when Gabriel de Clieu brought coffee seedlings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coffee Preparation
Coffee preparation is the making of liquid coffee using coffee beans. While the particular steps vary with the type of coffee and with the raw materials, the process includes four basic steps: raw coffee beans must be coffee roasting, roasted, the roasted coffee beans must then be coffee grinder, ground, and the ground coffee must then be mixed with hot or cold water (depending on the method of brewing) for a specific time (brewed coffee, brewed), the liquid coffee extraction must be separated from the used coffee grounds, used grounds, and finally, if desired, the extracted coffee is combined with other elements of the desired beverage, such as sweeteners, dairy products, dairy alternatives, or toppings (such as shaved chocolate). Coffee is usually brewed hot, at close to the boiling point of water, immediately before drinking, yielding a hot beverage capable of scalding if splashed or spilled; if not consumed promptly, coffee is often sealed into a vacuum flask or insulated ...

List Of Coffee Drinks
Coffee drinks are made by brewing water with ground coffee beans. The brewing is either done slowly, by Coffee filter, drip, filter, French press, moka pot or Coffee percolator, percolator, or done very quickly, under pressure, by an espresso machine. When put under the pressure of an espresso machine, the coffee is termed ''espresso'', while slow-brewed coffees are generally termed ''brewed coffee''. While all coffee drinks are based on either coffee or espresso, some drinks add milk or cream, some are made with steamed milk or non-dairy milks, or add water (like the Caffè americano, americano). Upon milk additions, coffee's flavor can vary with different syrups or sweeteners, alcoholic liqueurs, and even combinations of coffee with espresso or tea. There are many variations to the basic coffee or espresso bases. With the invention of the Gaggia machine, espresso and espresso with milk, such as cappuccino and latte, spread in popularity from Italy to the UK in the 1950s. It th ...

Coffee Roasting
Roasting coffee transforms the chemical and physical properties of Coffee processing, green coffee beans into roasted coffee products. The roasting process produces the characteristic flavor of coffee by causing the green coffee beans to change in taste. Unroasted beans contain similar if not higher levels of acids, protein, sugars, and caffeine as those that have been roasted, but lack the taste of roasted coffee beans due to the Maillard Reaction, Maillard and other chemical reactions that occur during roasting. Coffee tends to be roasted close to where it will be consumed, as green coffee is more stable than roasted beans. The vast majority of coffee is roasted commercially on a large scale, but small-scale commercial roasting has grown significantly with the trend toward Single-origin coffee, "single-origin" coffees served at specialty shops. Some coffee drinkers Home roasting coffee, roast coffee at home as a hobby in order to both experiment with the flavor profile of the b ...

Iced Coffee
Iced coffee is a coffee beverage served cold. It may be prepared either by brewing coffee normally (i.e. carafe, French press, etc.) and then serving it over ice or in cold milk or by cold brew coffee, brewing the coffee cold. In hot brewing, sweeteners and flavoring may be added before cooling, as they dissolve faster. Iced coffee can also be sweetened with syrup, pre-dissolved sugar in water. Iced coffee is regularly available in most coffee shops. Iced coffee is generally brewed at a higher strength than normal coffee, given that it is diluted by the melting ice. In Australia, "iced coffee" is a common term for packaged coffee-flavored and sweetened milk beverage. Iced coffee is made by brewing hot coffee, and pouring it over ice; Cold brew coffee is made without heat by steeping coffee grounds into lukewarm water. History Mazagran (coffee beverage), Mazagran, a cold, sweetened coffee beverage that originated in Algeria around 1840, has been described by locals as "the orig ...

Caffeine
Caffeine is a central nervous system (CNS) stimulant of the methylxanthine chemical classification, class and is the most commonly consumed Psychoactive drug, psychoactive substance globally. It is mainly used for its eugeroic (wakefulness promoting), ergogenic (physical performance-enhancing), or nootropic (cognitive-enhancing) properties. Caffeine acts by blocking the binding of adenosine at a number of adenosine receptor types, inhibiting the centrally depressant effects of adenosine and enhancing the release of acetylcholine. Caffeine has a three-dimensional structure similar to that of adenosine, which allows it to bind and block its receptors. Caffeine also increases Cyclic adenosine monophosphate, cyclic AMP levels through nonselective Phosphodiesterase inhibitor, inhibition of phosphodiesterase, increases calcium release from intracellular stores, and Receptor antagonist, antagonizes GABA receptor, GABA receptors, although these mechanisms typically occur at concentrati ...

Espresso
Espresso (, ) is a concentrated form of coffee produced by forcing hot water under high pressure through finely ground coffee beans. Originating in Italy, espresso has become one of the most popular coffee-brewing methods worldwide. It is characterized by its small serving size, typically 25–30 ml, and its distinctive layers: a dark body topped with a lighter-colored foam called "crema". Espresso machines use pressure to extract a highly concentrated coffee with a complex flavor profile in a short time, usually 25–30 seconds. The result is a beverage with a higher concentration of suspended and dissolved solids than regular drip coffee, giving espresso its characteristic body and intensity. While espresso contains more caffeine per unit volume than most coffee beverages, its typical serving size results in less caffeine per serving compared to larger drinks such as drip coffee. Espresso serves as the base for other coffee drinks, including cappuccino, Latte, caffè latte, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decaffeinated
Decaffeination is the removal of caffeine from coffee beans, cocoa, tea leaves, and other caffeine-containing materials. Decaffeinated products are commonly termed by the abbreviation decaf. To ensure product quality, manufacturers are required to test the newly decaffeinated coffee beans to make sure that caffeine concentration is relatively low. A caffeine content reduction of at least 97% is required under United States FDA standards. A 2006 study found decaffeinated drinks to contain typically 1–2% of the original caffeine content, but sometimes as much as 20%. Decaffeinated coffee Friedlieb Ferdinand Runge performed the first isolation of caffeine from coffee beans in 1820, after the German poet Goethe heard about his work on belladonna extract, and requested he perform an analysis on coffee beans. Though Runge was able to isolate the compound, he did not learn much about the chemistry of caffeine itself, nor did he seek to use the process commercially to produce deca ...
