Coffee and lifestyle seccion 1
Gatherings for coffee breaks often take place away from the actual work-area in a desinated cafeteria, tea room or outdoor area. As well as a chance for sustenance, the coffee break provides time for gossip and small talk, or a time to smoke a cigarette (thus the alternate term "Smoke break".
More generally, people can use the phrase "coffee break" to denote any break from work in any arena; popular culture often potrays housewives as taking a coffee break in their kitchens. Celebrity magazines use the term "coffee run" to describe people going for a short coffee break in the morning at a nearby cafe.

What is the difference between espresso and drip coffee?
A shot of espresso is made by forcing about 1.5 ounces of nearly boiling water through tightly packed, finely ground espresso coffee. If everything goes well, what comes out is a dark brown, slightly thick liquid with a small amount of crema (a foam, sort of like the head on a beer) on top.
There are many variables in the process of making a shot of espresso. The temperature of the water, the pressure of the water, the fineness of the ground coffee and how tightly the coffee is packed are just a few.
Espresso coffee is a blend of several different types of coffee beans from different countries. The beans are roasted until they are dark and oily-looking.
Drip coffee is made by dripping boiling water over ground coffee, which is ground more coarsely than espresso coffee. The water filters through the coffee and falls into a pot. This process is slower than the espresso process, and hot water is in contact with the ground coffee for much longer. Surprisingly, a cup of drip coffee has more caffeine than a shot of espresso.
Major chemicals in coffee
Caffeine
The world's primary source of caffeine is the coffee bean (the seed of the coffee plant), from which coffee is brewed. Caffeine content in coffee varies widely depending on the type of coffee bean and the method of preparation used; even beans within a given bush can show variations in concentration. In general, one serving of coffee ranges from 40 milligrams, for a single shot (30 milliliters) of arabica-variety espresso, to about 100 milligrams for a cup (120 milliliters) of drip coffee. Generally, dark-roast coffee has less caffeine than lighter roasts because the roasting process reduces the bean's caffeine content. Arabica coffee normally contains less caffeine than the robusta variety.Coffee also contains trace amounts of theophylline, but no theobromine.
Caffeine is a stimulant drug. It is a xanthine alkaloid compound that acts as a psychoactive stimulant and diuretic in humans. The word comes from the French term for coffee, café. Caffeine is also called guaranine when found in guarana, mateine when found in mate, and theine when found in tea; all of these names are synonyms for the same chemical compound.
Caffeic acid
Caffeic acid is a naturally occurring organic compound. This yellow solid consists of both phenolic and acrylic functional groups. It is found in all plants because it is a key intermediate in the biosynthesis of lignin, one of the principal sources of biomass.Caffeic acid is an antioxidant and it can also act as a carcinogenic inhibitor.
Coffee and Health
Recent research has uncovered additional stimulating effects of coffee which are not related to its caffeine content. Coffee contains an as yet unknown chemical agent which stimulates the production of cortisone and adrenaline, two stimulating hormones.
For occasions when one wants to enjoy the flavor of coffee with almost no stimulation, decaffeinated coffee (also called decaf) is available. This is coffee from which most of the caffeine has been removed, by the Swiss water process (which involves the soaking of raw beans to remove the caffeine) or the use of a chemical solvent such as trichloroethylene ("tri"), or the more popular methylene chloride, in a similar process. Another solvent used is ethyl acetate; the resultant decaffeinated coffee is marketed as "natural decaf" because ethyl acetate is naturally present in fruit. Extraction with supercritical carbon dioxide has also been employed.Decaffeinated coffee usually loses some flavor over normal coffee. There are also coffee alternatives that resemble coffee in taste but contain no caffeine (see below). These are available both in ground form for brewing and in instant form. Caffeine dependency and withdrawal symptoms are well-documented.
Benefets of Coffee
Reduced risk of Alzheimer's disease and Dementia
Reduced risk of gallstone disease
Drinking caffeinated coffee has been correlated with a lower incidence of gallstones and gallbladder disease in both men and women in two studies performed by the Harvard School of Public Health. A lessened risk was not seen in those who drank decaffeinated coffee.
Reduced risk of Parkinson's disease
A study comparing heavy coffee drinkers (3.5 cups a day) with non-drinkers found that the coffee drinkers were significantly less likely to contract Parkinson's disease later in life. Likewise, a second study found an inverse relationship between the amount of coffee regularly drunk and the likelihood of developing Parkinson's disease.
Cognitive performance
Many people drink coffee for its ability to increase short term recall and increase IQ. Likewise, in tests of simple reaction time, choice reaction time, incidental verbal memory, and visuospatial reasoning, participants who regularly drank coffee were found to perform better on all tests, with a positive relationship between test scores and the amount of coffee regularly drunk. Elderly participants were found to have the largest effect associated with regular coffee drinking. Another study found that women over the age of 80 performed significantly better on cognitive tests if they had regularly drunk coffee over their lifetimes.
Analgesic enhancement
Coffee contains caffeine, which increases the effectiveness of pain killers, especially migraine and headache medications. For this reason, many over-the-counter headache drugs include caffeine in their formula.
Antidiabetic
Coffee intake may reduce one's risk of diabetes mellitus type 2 by up to half. While this was originally noticed in patients who consumed high amounts (7 cups a day), the relationship was later shown to be linear.
Liver protection
Coffee can also reduce the incidence of cirrhosis of the liver and has been linked to a reduced risk of hepatocellular carcinoma, a primary liver cancer that usually arises in patients with preexisting cirrhosis. The exact mechanism and the amount of coffee needed to achieve a beneficial effect are as yet unclear.
Cancer
Coffee consumption is also correlated to a reduced risk of oral, esophageal, and pharyngeal cancer.In ovarian cancer, no benefit was found.In the Nurses Health Study, a modest reduction in breast cancer was observed in postmenopausal women only, which was not confirmed in decaffeinated coffee.According to one research, coffee protects from liver cancer. Another preliminary study found a correlation between coffee consumption and a lower risk of aggressive prostate cancer.
Cardioprotective
According to the longitudial study led by Esther Lopez-Garcia of Universidad Autonoma de Madrid, coffee reduces the incidence of dying from heart disease .
Laxative/diuretic
Coffee is also a powerful stimulant for peristalsis and is sometimes considered to prevent constipation. However, coffee can also cause excessively loose bowel movements. The stimulative effect of coffee consumption on the colon is found in both caffeinated and decaffeinated coffee.
Practitioners in alternative medicine often recommend coffee enemas for "cleansing of the colon" due to its stimulus of peristalsis, although medicine has not proved any benefits of the practice.
Contrary to popular belief, caffeine does not act as a diuretic when consumed in moderation, and does not lead to dehydration or to a water-electrolyte imbalance; current evidence suggests that caffeinated beverages contribute to the body's daily fluid requirements no differently from pure water.
Antioxidant
Coffee contains the anticancer compound methylpyridinium. This compound is not present in significant amounts in other food materials. Methylpyridinium is not present in raw coffee beans but is formed during the roasting process from trigonelline, which is common in raw coffee beans. It is present in both caffeinated and decaffeinated coffee, and even in instant coffee.
Prevention of dental caries
The tannins in coffee may reduce the cariogenic potential of foods. In vitro experiments have shown that these polyphenolic compounds may interfere with glucosyltransferase activity of mutans streptococci, which may reduce plaque formation.
Gout
Coffee consumption decreased risk of gout in men over age 40. In a large study of over 45,000 men over a 12-year period, the risk for developing gout in men over 40 was inversely proportional with the amount of coffee consumed.

Robusta bean
History of coffee
According to a coffee history legend, an Arabian shepherd named Kaldi found his goats dancing joyously around a dark green leafed shrub with bright red cherries in the southern tip of the Arabian Peninsula. Kaldi soon determined that it was the bright red cherries on the shrub that were causing the peculiar euphoria and after trying the cherries himself, he learned of their powerful effect. The stimulating effect was then exploited by monks at a local monastery to stay awake during extended hours of prayer and distributed to other monasteries around the world. Coffee was born.
Despite the appeal of such a legend, recent botanical evidence suggests a different coffee bean origin. This evidence indicates that the history of the coffee bean beagan on the plateaus of central Ethiopia and somehow must have been brought to Yemen where it was cultivated since the 6th century. Upon introduction of the first coffee houses in Cairo and Mecca coffee became a passion rather than just a stimulant.

Have you ever known Latte art?
Mocha coffee cup
A Café mocha is a variant of a caffè latte. Like a latte, it is typically one third espresso and two thirds steamed milk, but a portion of chocolate is added, typically in the form of sweet cocoa powder, although many varieties use chocolate syrup. Mochas can contain dark or milk chocolate.
Like cappuccino, café mochas contain the well-known milk froth on top, although they are sometimes served with whipped cream instead. They are usually topped with a dusting of either cinnamon or cocoa powder. Marshmallows may also be added on top for flavor and decoration.
A variant is white café mocha, made with white chocolate instead of milk or dark. There are also variants of the drink that mix the two syrups; this mixture is referred to by several names, including black and white mocha, tan mocha, tuxedo mocha and zebra.
Café mocha takes its name from the Red Sea coastal town of Mocha, Yemen, which as far back as the fifteenth century was a dominant exporter of coffee, especially to areas around the Arabian Peninsula.
Mocha Coffee Bean
Mocha is also used to describe a coffee bean with a "chocolatey" taste. Smaller and rounder than most other varieties, these beans are derived from the coffee species Coffea arabica, which is native to Ethiopia and Yemen. "Mocha coffee" can refer either to the coffee-with-chocolate drink, or simply to coffee brewed with mocha beans, which were originally cultivated in Yemen and exported through the port of Mocha.

coffee Americano
A long black is a style of coffee, most commonly found in New Zealand and Australia, but now becoming available in the UK, predominantly in London. It is made by pulling a double-shot of espresso over hot water (usually the water is also heated by the espresso machine). A long black is similar to an Americano, which is made by adding hot water to espresso shots, but it retains the crema and is less voluminous, therefore more strongly flavoured.
A long black is considered by the emerging palates[who?] to be a true espresso experience rather than what the major coffee chains have produced up to date, specifically the Americano. The order in which a long black is made (water first, espresso second) is important; reversing the steps will destroy the crema from the espresso shots.
Short black is an Australasian synonym for the basic espresso.
Lungo
Lungo is Italian for 'long', and refers to the coffee beverage made by using an espresso machine to make an espresso (single or double dose or shot) with much more water (generally twice as much), resulting in a stretched espresso, a lungo. A normal espresso takes from 18 up to 30 seconds to pull, and fills 25 to 30 millilitres, while a lungo may take up to a minute to pull, and might fill 50 to 60 millilitres.In French it is called café allongé
Red eye
A red eye is a fortified coffee drinks in which espresso is combined with normal drip coffee. It is known by various names, some of which refer to different variants.
Drip coffee to which espresso is added may be called a red eye, black eye, or dead eye, accordingly as one, two, or three shots are added.
Traditionally, these drinks were referred to as "Black Eye" with 2 added shot of espresso or "red eye" with 1 added shots of espresso. While "black eye" was named for the appearance of the circular black marking caused by pouring the shot on the top of the cup of coffee with cream, the "red eye" was named for the extra added zip needed to stay awake through a "red eye" flight from the West Coast to New York. "Dead eye" is partly rhyme, partly "raise the dead".
It may also be referred to as a Canadiano, particularly if the drip coffee is added to the espresso (rather than espresso to the drip), punning on an Americano, which is hot water added to espresso.

What's Espresso?
And so you can begin to understand modern espresso, how to prepare it properly, and the traditions behind this wonderful beverage.
Do you love cappucino?
While a cappuccino is traditionally drank during breakfast in Italy, it is a diverse drink that tastes great throughout the day.
Variations on the cappucino include cappuccino senza schiuma, literally cappuccino without the foam which is essentially an espresso topped with hot milk (no foam) - also called a cafè latte.If you want a long glass of cold black coffee, ask for a cafè freddo.
After a while you will get fed up with luke-warm Italian coffee and ask for your coffee to be served very hot (molto caldo), of course everyone at the bar will gasp and fall silent as you will be breaking yet another Italian coffee rule, once again exposing yourself as a tourist.
My love coffe
Cappucino is the name of my favorite coffe cup.

coffee culture
In some countries, notably in northern Europe, coffee parties are a popular form of entertainment. Besides coffee, the host or hostess at the coffee party also serves cake and pastries, sometimes homemade.
Coffee plays a large role in much history and literature because of the large effects the coffee industry has had on cultures where it is produced or consumed. Coffee is often mentioned as one of the main economic goods used in imperial control of trade, and with colonized trade patterns in "goods" such as slaves, coffee, and sugar, which defined Brazilian trade, for example, for centuries. Coffee in culture or trade is a central theme and prominently referenced in much poetry, fiction, and regional history.

Coffee bean
A coffee bean is the seed of the coffee plant (the pit inside the red or purple fruit). Even though they are seeds, they are referred to as 'beans' because of their resemblance. The fruits, coffee cherries or coffee berries, most commonly contain two stones with their flat sides together. In a crop of coffee, a small percentage of cherries contain a single bean, instead of the usual two. This is called a peaberry. Coffee beans consist mostly of endosperm that contains 0.8 - 2.5 % caffeine, which is one of the main reasons the plants are cultivated. As coffee is one of the world's most widely consumed beverages, coffee beans are a major cash crop, and an important export product for some countries. It is considered a regularly consumed beverage in the United States - as popular as soft drinks and even water - and because of the volume consumed, it is here that coffee is highest in demand.
Species of coffee plant include Coffea arabica, Coffea benghalensis, Coffea canephora, Coffea congensis, Coffea excelsa, Coffea gallienii, Coffea bonnieri, Coffea mogeneti, Coffea liberica, and Coffea stenophylla. The seeds of different species produce coffee with slightly different characteristics.
There are two main types of coffee beans: Coffea Arabica (more commonly referred to as "Arabica ") and Coffea Canephora (Robusta). These two types make up over 90% of coffee beans sold worldwide. Arabica typically produce higher quality coffees, while Robusta are more economically favorable for their heartiness.[vague]
Because environmental factors deeply affect the flavor of the beans, they are usually identified not by type but by geographic location.

Love to Coffee Begining
My Grandma introduced me to coffee when I was young and I still drink it black. I was probably nine years old when I had my first taste, then at twelve a small cup, and later a full mug. While I observed that many of my family members added sugar and cream, I thought there was something cool and authentic about her drinking it black. So, I followed in kind.
Recently at Brazen Careerist, in the coffee group, a coffee aficiando asked the question:
So, how did everyone get started drinking coffee?
Fellow members were quick to answer, and many were introduced by someone in their family. I wasn’t the only one. Curious, I gave my Grandma a call to find out how her affair with coffee began.
My Grandma still drinks Folgers and Maxwell House, but my family recently bought her a Kerig K-Cup, so she’s beginning to explore… Regardless of her coffee brand preferences, Grandma told me that she was likewise introduced to coffee when she was young. Her Grandma use to put a few drops of coffee into her milk, and it was the fragrance that drew her in. It wasn’t until she was older that she moved from coffee with sugar and cream to coffee black; she didn’t enjoy the taste of powdered milk offered at restaurants.
Like me, my Grandma’s affair with coffee was and continues to be social. It wasn’t just about the coffee.
So, now it’s your turn. How did your affair with coffee begin?
