The Magic of Coffee

The amount of caffeine in a cup of coffee can vary greatly, depending on its origin or the composition of the blend, the method of brewing and the strength of the brew. Coffee used in recipes and drinks is very strong, usually double strength.

Instant, or soluble, coffee generally contains less caffeine than roast and ground coffee but may be consumed in greater volume. Robusta coffees have about twice as much caffeine as Arabicas.

Percolator Coffee For A Crowd
When brewing coffee for a crowd, use 2 cups percolator grind coffee for 30 (6 ounce) servings. Brew according to manufacturer's directions. For a larger coffee maker (55-60 cups), just double the amount of coffee.

Italian Espresso
Italian Espresso Caffè is a small cup of very strong coffee that Italians not only sip from tiny cups, it is also brewed in a special machine that forces boiling water through the dark roasted, finely ground coffee beans. A 'cup' is usually understood to contain 150 ml (5 oz in the United States) but an Espresso Caffè may be as small as 40 ml. Espresso Caffè is also used as the basis for other drinks like: caffè late, cappuccino, caffè macchiato, Espresso con Panna and many more.

Since its discovery in an Ethiopian rainforest centuries ago, coffee has brewed up a rich and troubled history, according to Uncommon Grounds, a sweeping book by business writer Mark Pendergrast. Over the years, the beverage has fomented revolution, spurred deforestation, enriched a few while impoverishing the many, and addicted millions with its psychoactive caffeine. Coffee is now the world's second most valuable legal commodity, behind oil, according to Pendergrast, who is also author of the  interesting book  "For God, Country, and Coca-Cola".

A good cup of coffee can turn the worst day tolerable, can provide an all important moment of contemplation, can rekindle a romance," he writes. "And yet, poetic as its taste may be, coffee's history is rife with controversy and politics." For example, coffee bankrolled Idi Amin's genocidal regime in Uganda and the Sandinistas' revolution in Nicaragua. Uncommon Grounds provides some fascinating tidbits. Did you know that coffeehouses helped spawn the French and American revolutions? Or that coffee supplanted alcohol as a favorite breakfast drink in Britain in the late 1600s, and later became a patriotic American beverage after the Boston Tea Party?

Pendergrast also details the rise and fall of regional coffee brands in the United States, the role of advertising in the industry, the global economic impact of coffee prices, and the recent emergence of specialty-coffee retailers--Starbucks, for example. Finally, he explores the social and environmental ramifications of coffee and highlights recent attempts to encourage a livable wage and environmental protection in coffee-producing nations such as Brazil. Pendergrast also includes an appendix on "how to brew the perfect cup." This wide-ranging book is a good read for those curious about the history and context behind that morning cup of coffee, as well as for those strictly interested in the business side of the industry.
