A vacuum coffee maker brews coffee using two chambers where vapor pressure and vacuum produce coffee. This type of coffee maker is also known as vac pot, siphon or syphon coffee maker, and was invented by Loeff of Berlin in the 1830s. These devices have since been used for more than a century in many parts of the world and more recently have been given a new use by bartenders and chefs to make hot cocktails and broths.[20]
Drinking coffee without adding sugar can reduce the chances of heart disease and inflammation, thereby lowering the risk of cardiovascular disease [5] . Studies have shown that coffee consumption lowers the risk of stroke by 20 per cent [6] , [7] , [8] . However, coffee may cause a slight increase in blood pressure, which doesn't cause a problem though.
Arabica coffee, which accounts for about three-quarters of the coffee cultivated worldwide, is grown throughout Latin America, Central and East Africa, India and, to some extent, Indonesia. Robusta coffee is grown in West and Central Africa, throughout South-East Asia and, to some extent, in Brazil. These are only two of the many kinds of coffee grown all over the world.
A Café Rápido y Sucio or a Quick & Dirty Coffee, is simply three shots of espresso topped with chocolate or mocha syrup. Unlike a café mocha which has milk added or an Americano which has water added, a Café Rápido y Sucio or a Quick & Dirty Coffee is espresso and chocolate only. Any variation of this drink containing more than three shots of espresso would be referred to as a Fast & Filthy Coffee.
Academy of Nutrition and Dietetics' spokeswoman and registered dietitian Joan Salge Blake says she considers increased cognitive function to be one of coffee's healthiest perks. A study published in the "American Journal of Epidemiology" in 2002 found that current coffee consumption, as well lifetime caffeine use, may be correlated to better performance on cognitive tests among women. For men, coffee consumption is linked to slower cognitive decline. Overall, coffee may reduce both cognitive and motor deficiency associated with aging.

Increasing age leads to decreased cognitive skills and increased risk of Dementia, Parkinson’s and Alzheimer’s disease. Having black coffee in the morning enhances the brain function. Black coffee helps the brain to stay active and thus helps in boosting the memory power. It also keeps the nerves active which in turn keeps dementia at bay. Studies say regular consumption of black coffee reduces risk of Alzheimer’s by 65 per cent and Parkinson’s by 60 per cent.
