The Dangers Of Drinking Coffee
Coffee is no longer thought to be a risk factor for coronary heart disease. A 2012 meta-analysis concluded that people who drank moderate amounts of coffee had a lower rate of heart failure, with the biggest effect found for those who drank more than four cups a day. Moreover, in one study, habitual coffee consumption was associated with improved vascular function. In a ten year study among 50,739 US women (mean age, 63 years) free of depressive symptoms at baseline (in 1996), coffee consumption was negatively correlated with risk of developing clinical depression. A review published in 2004 indicated a negative correlation between suicide rates and coffee consumption. It was suggested that the action of caffeine in blocking the inhibitory effects of adenosine on dopamine nerves in the brain reduced feelings of depression. Coffee extracts have been shown to inhibit 11β-hydroxysteroid dehydrogenase type 1, an enzyme which converts cortisone to cortisol and is in current pharmaceutical development for the treatment of diabetes type 2 and metabolic syndrome.
All coffee plants are classified in the large family Rubiaceae. They are evergreen shrubs or small trees that may grow 560;m (1560;ft) tall when unpruned. The leaves are dark green and glossy, usually 10-1560;cm (4-660;in) long and 660;cm (460;in) wide, simple, entire, and opposite. Petioles of opposite leaves fuse at base to form interpetiolar stipules, characteristic of Rubiaceae. The flowers are axillary, and clusters of fragrant white flowers bloom simultaneously. Gynoecium consists of inferior ovary, also characteristic of Rubiaceae. Flowers followed by oval berries of about 560;cm (660;in). Green when immature, they ripen to yellow, then crimson, before turning black on drying. Each berry usually contains two seeds, but 5-10% of the berries have only one; these are called peaberries. Arabica berries ripen in six to eight months, while robusta take nine to eleven months.
A contemporary term for a person who makes coffee beverages, often a coffeehouse employee, is a barista. Though the title is not regulated, baristas may be trained in numerous methods of brewing, and may be knowledgeable about or involved in the production of coffee at every stage, from bean to cup.

Another commonly used method is solvent extraction, typically using oil (extracted from roasted coffee) or ethyl acetate as a solvent. In this process, solvent is added to moistened green coffee beans to extract most of the caffeine from the beans. After the beans are removed from the solvent, they are steam-stripped to remove any residual solvent. The caffeine is then recovered from the solvent, and the solvent is re-used. The Swiss Water Process is also used for decaffeination. Decaffeinated coffee beans have a residual caffeine content of about 1% on a dry basis. Not all facilities have decaffeination operations, and decaffeinated green coffee beans are purchased by many facilities that produce decaffeinated coffee.

Starbucks Coffeehouses began to give consumers a different kind of feeling about drinking coffee. Even employees, called partners, get a different kind of experience than one a regular barista would expect. Between two and six partners are working at any given time.
The international coffeehouse chain Starbucks began as a modest business roasting and selling quality coffee beans in 1971, by three college students Jerry Baldwin, Gordon Bowker and Zev Siegl. The first store opened on March 30, 1971 at the Pike Place Market in Seattle, followed by a second and third over the next two years. Entrepreneur Howard Schultz joined the company in 1982 as Director of Retail Operations and Marketing, and pushed to sell premade espresso coffee. The others were reluctant, but Schultz opened Il Giornale in Seattle in April 198 He bought the other owners out in March 1987 and pushed on with plans to expand-from 1987 to the end of 1991, the chain (rebranded from Il Giornale to Starbucks) expanded to over 100 outlets. The company has 16,600 stores in over 40 countries worldwide.
