Pisco sour

A pisco sour is a cocktail typical of South American cuisine. The drink's name comes from pisco, which is its base liquor, and the cocktail term sour, in reference to sour citrus juice and sweetener components. The Peruvian pisco sour uses Peruvian pisco as the base liquor and adds Key lime (or lemon) juice, syrup, ice, egg white, and Angostura bitters. The Chilean version is similar, but uses Chilean pisco and pica lime, and excludes the bitters and egg white. Other variants of the cocktail include those created with fruits like pineapple or plants such as coca leaves.

The cocktail originated in Lima, Peru, and was invented by Victor Vaughen Morris, an American bartender, in the early 1920s. Morris left the United States in 1903 to work in Cerro de Pasco, a city in central Peru. In 1916, he opened Morris' Bar in Lima, and his saloon quickly became a popular spot for the Peruvian upper class and English-speaking foreigners. The pisco sour underwent several changes until Mario Bruiget, a Peruvian bartender working at Morris' Bar, created the modern Peruvian recipe of the cocktail in the latter part of the 1920s by adding Angostura bitters and egg whites to the mix.

Pisco

Pisco is a colorless or yellowish-to-amber colored brandy produced in winemaking regions of Peru. Made by distilling grape wine into a high-proof spirit, it was developed by 16th century Spanish settlers as an alternative to orujo, a pomace brandy that was being imported from Spain. It had the advantages of being produced from abundant domestically grown fruit and reducing the volume of alcoholic beverages transported to remote locations.

Annual pisco production in 2013 reached 1 million litres in Chile and 7.2 million litres in Peru.

Etymology

The oldest use of the word pisco to denote Peruvian aguardiente dates from 1764. However, there are several, often nationalist theories about the origin of the word pisco. Pisco may have received its Quechua name from the Peruvian town of Pisco – once an important colonial port for the exportation of viticultural products – located on the coast of Peru in the valley of Pisco, by the river with the same name. Chilean linguist Rodolfo Lenz claimed that the word pisco was used all along the Pacific coast of the Americas from Arauco to Guatemala and that the word would be of Quechua origin meaning "bird".

Taste

Taste, gustatory perception, or gustation is the sensory impression of food or other substances on the tongue and is one of the five traditional senses.

Taste is the sensation produced when a substance in the mouth reacts chemically with taste receptor cells located on taste buds. Taste, along with smell (olfaction) and trigeminal nerve stimulation (registering texture, pain, and temperature), determines flavors of food or other substances. Humans have taste receptors on taste buds (gustatory calyculi) and other areas including the upper surface of the tongue and the epiglottis.

The tongue is covered with thousands of small bumps called papillae, which are visible to the naked eye. Within each papilla are hundreds of taste buds. The exception to this is the filiform papillae that do not contain taste buds. There are between 2000 and 5000 taste buds that are located on the back and front of the tongue. Others are located on the roof, sides and back of the mouth, and in the throat. Each taste bud contains 50 to 100 taste receptor cells.
