Caffeine is a central nervous system (CNS) stimulant of the methylxanthine class. It is mainly used recreationally, as a eugeroic (wakefulness promoter) or as a mild cognitive enhancer to increase alertness and attentional performance. Caffeine acts by blocking binding of adenosine to the adenosine A1 receptor, which enhances release of the neurotransmitter 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 AMP levels through nonselective inhibition of phosphodiesterase.
Chocolate or cocoa is a food made from roasted and ground cacao seed kernels that is available as a liquid, solid, or paste, either on its own or as a flavoring agent in other foods. Cacao has been consumed in some form since at least the Olmec civilization, and the majority of Mesoamerican people, including the Maya and Aztecs, made chocolate beverages.
Theobromine, also known as xantheose, is the principal alkaloid of Theobroma cacao. Theobromine is slightly water-soluble (330 mg/L) with a bitter taste. In industry, theobromine is used as an additive and precursor to some cosmetics. It is found in chocolate, as well as in a number of other foods, including the leaves of the tea plant, and the kola nut. It is a white or colourless solid, but commercial samples can appear yellowish.
Espresso is one of the most popular coffee-brewing methods, of Italian origin. The French also made a significant contribution to the invention of the first coffee makers, predecessors of today's espresso machines, and generally to the café culture. Espresso can be made with a wide variety of coffee beans and roast degrees, in which a small amount of nearly boiling water is forced under pressure through finely-ground coffee beans. Espresso is the most common way of making coffee in southern Europe, especially in Italy, France, Spain, Portugal and Greece, but it is also popular in the rest of the world.
The cocoa bean or simply cocoa, also called cacao, is the dried and fully fermented seed of Theobroma cacao, from which cocoa solids and cocoa butter can be extracted. Cocoa beans native to the Amazon rainforest are the basis of chocolate, and Mesoamerican foods including tejate, an indigenous Mexican drink.
Coffee is a beverage prepared from roasted coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content. It has the highest sales in the world market for hot drinks.
A caffeinated drink, or caffeinated beverage, is a drink that contains caffeine, a stimulant that is legal practically all over the world. Some are naturally caffeinated while others have caffeine added as an ingredient.
A chocoholic is a person who craves or compulsively consumes chocolate. The word "chocoholic" was first used in 1968, according to Merriam-Webster. It is a portmanteau of "chocolate" and "alcoholic". The term is used loosely or humorously to describe a person who is inordinately fond of chocolate; however, there is medical evidence to support the existence of actual addiction to chocolate. Psychoactive constituents of chocolate that trigger a ‘feel-good’ reaction for the consumer include tryptophan and phenylethylamine, which may contribute to cravings and addiction-like responses, particularly in people with specific genetic alleles. The quantity of sugars used in chocolate confections also impacts the psychoactive effects of chocolate.
Decaffeination is the removal ("de-") of caffeine from coffee beans, cocoa, tea leaves, and other caffeine-containing materials. Decaffeinated products are commonly termed by the abbreviation decaf. Decaffeinated drinks contain typically 1–2% of the original caffeine content, and sometimes as much as 20%.
White chocolate is a confectionery typically made of sugar, milk, and cocoa butter, but no cocoa solids. It is pale ivory in color, and lacks many of the compounds found in milk, dark, and other chocolates. It is solid at room temperature because the melting point of cocoa butter, the only white cocoa bean component, is 35 °C (95 °F).
A coffee bean is a fruit from the Coffea plant and the source for coffee. It is the pip inside the red or purple fruit. This fruit is often referred to as a coffee cherry, and like the cherry, it is a stone fruit. Even though the coffee beans are not technically beans, they are referred to as such because of their resemblance to true beans. The fruits most commonly contain two stones with their flat sides together. A small percentage of cherries contain a single seed, instead of the usual two, called a "peaberry". The peaberry occurs only between 10% and 15% of the time, and it is a fairly common belief that they have more flavour than normal coffee beans. Like Brazil nuts and white rice, coffee beans consist mostly of endosperm.
A caffè mocha, also called mocaccino, is a chocolate-flavoured warm beverage that is a variant of a caffè latte, commonly served in a glass rather than a mug. Other commonly used spellings are mochaccino and also mochachino. The name is derived from the city of Mokha, Yemen, which was one of the centres of early coffee trade. Like latte, the name is commonly shortened to just mocha.
White coffee can refer to any of a number of different kinds of coffees or coffee substitutes worldwide.
Roasting coffee transforms the chemical and physical properties of green coffee beans into roasted coffee products. The roasting process is what 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 and other chemical reactions that occur during roasting.
Coffee substitutes are non-coffee products, usually without caffeine, that are used to imitate coffee. Coffee substitutes can be used for medical, economic and religious reasons, or simply because coffee is not readily available. Roasted grain beverages are common substitutes for coffee.
The following outline is provided as an overview of and topical guide to chocolate:
Santomean cuisine comprises the cuisine, dishes and foods of São Tomé and Príncipe, a Portuguese-speaking island nation in the Gulf of Guinea, off the western equatorial coast of Central Africa. The country consists of two archipelagos around the two main islands: São Tomé and Príncipe, located about 140 kilometres (87 mi) apart and about 250 and 225 kilometres, respectively, off the northwestern coast of Gabon.
Spella Caffè is a coffee shop in Portland, Oregon, United States. Andrea Spella started the business as a cart in 2006, before opening a brick and mortar space in downtown Portland in 2010. The business has garnered a positive reception, and has been cited as an influence for other coffee company founders.
