Coffee

You’ll be pleased to learn that many of the foods and drinks you love are not just “okay” as an occasional indulgence–they’re good for you! Let’s begin with coffee and tea…and I invite you to read my related articles on wine and beer, and on chocolate.

Coffee is made from the roasted and ground seeds of several tropical trees or shrubs of the genus Coffea.

An Arabian legend tells of a goatherd who made a beverage from berries growing on strange shrubs, and after drinking it experienced extraordinary lucidity and wakefulness. The shrubs were said to have been planted by the descendants of the Queen of Sheba, who came from Ethiopia, where Coffea arabica originates.

Nearly 20,000 scientific studies to date have been conducted on coffee or caffeine. Here, in a nutshell, are the results: not only is drinking coffee in moderation no threat to health, it actually can be a boon. It is harmless even during pregnancy, and children are no more sensitive to caffeine than adults.

The average American consumes about 200 milligrams of caffeine daily, roughly the equivalent of two cups of coffee (a figure that of course includes those who drink none at all). “Moderate” consumption is generally defined as 300 mg daily–two to five cups of coffee, or four to eight cups of hot tea, depending on the size of the cup.

Which has more caffeine, coffee or tea? It depends. On a pound-for-pound basis, tea has more. But because less tea is required to make a cup of tea, generally a cup of coffee has more caffeine–approximately twice as much. There are also significant variations in the variety of coffee or tea and the brewing method used. Dark-roasted coffees may contain less caffeine than more lightly roasted beans; arabica beans tend to have less caffeine and milder flavor than robusta.

“Decaffeinated” coffee and tea contain about 5 mg per cup.

Caffeine is a central nervous system stimulant. While individuals vary in their sensitivity to caffeine, some generalizations apply. Caffeine can increase the speed of rapid information processing, alertness, energy, endurance, motivation, and concentration. All this has important implications especially for night shift workers and for drivers, as well as for anyone wanting to remain productive on the job after lunch. This alertness-enhancing effect also can relieve the malaise associated with the common cold. (Now, that’s good news for those of us who prefer coffee but feel obligated to switch to herbal tea with the onset of a sore throat or stuffy nose!)

Caffeine soothes headaches by constricting blood vessels in the brain, which in turn reduces cranial pressure. So it’s no surprise that it’s an active ingredient in headache relievers.

Some studies have linked caffeine consumption to a decline in levels of depression and anxiety.

Caffeine has long been known to help asthmatics, many of whom have found regular consumption of coffee to have a moderating effect on attacks. That’s no surprise, either, thanks to the ingredient theophylline–a drug prescribed for symptomatic relief of bronchial asthma.

Higher caffeine intake is associated with a significantly lower incidence of Parkinson’s disease. That’s because caffeine intake reduces the amount of dopamine depletion, one of the characteristics of Parkinson’s.

Last but not least, caffeine stimulates metabolism.

Caffeine aside, coffee has a complex chemical composition. A characteristic of many plants is the abundance of compounds with antioxidant properties, and coffee is no exception. Flavonoids are particularly widespread in plants and likewise important in disease protection.

Antioxidants reduce the risk of cancer and prevent good (HDL) cholesterol from turning into bad (LDL) cholesterol, a cause of heart disease. Antioxidants neutralize the effect of “free radicals,” highly reactive molecules that travel around the body causing chemical chain reactions that can damage cells, by binding with the extra electrons. Free radicals also have been implicated in strokes, cancer, and the aging process. Substances with antioxidant activity are found to be generated in the roasting process.

Coffee is a good dietary source of potassium. That makes coffee a good choice as a diuretic; potassium loss is an undesirable side effect of most diuretics. Coffee can reduce the risk of cirrhosis of the liver.

Tea is made from the leaves of a shrub of the Camellia genus.

The Chinese first gathered tea leaves in the wild, and have cultivated the tea plant at least as far back as 350 AD. The court of England’s Charles II in the 17th century established tea as a fashionable drink for the elite.

The firing, fermenting, and/or oxidizing that is done to the leaves determines whether the tea will be green, black, or oolong.

Tea is a source of vitamins A and B6, thiamin, and riboflavin; nicotinic, pantothenic, ascorbic, and folic acids; manganese, potassium, and fluoride.

Flavonoids are found in all types of tea; green tea has the highest concentration. Tea is being studied for its benefits in enhancing immune function, lowering LDL and raising HDL levels, reducing blood pressure, thinning blood, reducing the risk of heart attack, stroke, and cancer, increasing longevity, aiding digestion, and promoting dental health.

There is convincing evidence for a protective effect of both coffee and tea against colorectal cancers, the second leading cause of cancer-related deaths in the United States. High coffee intake decreases the excretion of bile acids, which are suspected carcinogens to the colon. Because of its diuretic properties, caffeine may help lower the risk of bladder cancer.

Greater intakes of coffee and tea, both regular and decaffeinated, were associated with a decreased risk of kidney stone formation, significantly more so than water. (A slight advantage was found in caffeine-containing coffee over decaffeinated.) Interestingly, increased consumption of apple and grapefruit juices correlated with increased risk of stone formation.

One study has found that people who drink coffee are less likely to suffer heart disease than are tea drinkers. This may not, however, be a straight cause-and-effect relationship: possibly people who choose to drink coffee have more youthful/healthful lifestyles in other respects.

Science has debunked the dark myths that caffeine contributes to breast cancer, bladder cancer, ulcers, indigestion, and osteoporosis.

Is there any reason not to consume caffeine? In some patients, caffeine is associated with temporary rises in blood pressure, so people with high blood pressure might be advised to avoid caffeine during high-stress times.

Moreover, those more sensitive to caffeine may not be able to drink coffee or tea late in the day because caffeine delays the onset of sleep. Worse, some people may not be aware that they are not as rested the following day as they should be, and thus may be more prone to fatigue-related accidents.

Is it possible to become addicted to caffeine? Coffee drinkers do not exhibit the behaviors that define addiction–severe withdrawal symptoms, tolerance, the need to consume the addictive substance at all costs, and antisocial behavior including crimes. Neither coffee nor other products containing caffeine are classified by drug dependence experts as addictive.

Nevertheless, giving up caffeine suddenly can be unpleasant. The most common withdrawal symptoms include headaches, fatigue, drowsiness, irritability, depression, and flu-like feelings. Weaning oneself gradually–say, over a week–should minimize the discomfort.

So drink up–without the guilt.

Belonging to a coffee club is a great joy for lovers of fine coffee. The concept of a coffee club is very recent, but is already revolutionizing the coffee-drinking world. The best coffee in Chicago, St. Louis, San Francisco (and need we mention Seattle) is available with club memberships in these and many other American cities. Joining a coffee club allows you to save lots of money and get in on special deals which are only available to members. Every month you receive a coffee shipment delivered to your door with a surprise selection of great coffees and teas as you choose. This is the best way to introduce yourself and your friends and relations to new coffees, letting you sample different types and discover new brews that you really love. This is a great boon to people who live in rural areas far from the madding crowd but also far from the nearest coffee shop. It’s very convenient not having to run down to the shop for your coffee in the morning and assures you a steady supply.

Coffee clubs are springing up all over the country, and the different clubs offer different choices so it isn’t hard to find a club that fits your tastes and budget. Many of the coffee clubs now offer a coffee of the month option, so in addition to being able to specify your favorite grinds and types you can allow the coffee company to bring you a surprise every month! Some clubs let you specify the flavor you prefer, or you can just go with the flow and let the company make its favorite picks. Usually coffee of the month samples consist of a pound of coffee each time, but you can vary the amount at your discretion. There are coffee clubs which publish newsletters containing interesting articles about the featured coffee of the month, and also recipes and useful hints about making coffee, removing coffee stains, etc. Coffee clubs usually offer a members only discount, thus passing onto the consumer the savings the company enjoys by being able to buy gourmet coffee and tea in bulk with a guaranteed clientele. If some special offering or sale comes up the club members hear about it first through the club newsletter; and coffee clubs often offer gift books of coffee recipes or coffee mugs as gifts.

Coffee clubs usually offer flexible terms of membership. Often you can join for periods of three, six, or twelve months’ memberships; and can specify whether you want ground beans or whole beans; which type of grind you prefer; and whether you want regular or flavored, decaf or caffeinated. There are endless choices available which cater to each individual taste and budget. Membership in a coffee club makes a terrific gift for the coffee lover on your gift list, whether for Christmas, birthday, thank you, or especially as a business gift, which includes a gift card in your name.

For some of the very best coffee in Chicago the place to go is the Intelligentsia coffee company, which offers a wide selection of gourmet coffee and tea. Besides their retail shop on Broadway, Intelligentsia offers one of the most popular coffee of the month programs in the country.

With the large multi-national coffee companies focused purely on coffee as a commodity rather then a drink to be savoured, it allowed a new sector to emerge in the coffee industry: Speciality Coffee. Speciality coffee was nothing new, rather the opposite; it stripped coffee making back down to the grass roots: pure arabica beans, roasted long enough for the coffee to fully develop all its characteristics and flavours.

During the ‘Dark Age’ of coffee there was still excellent coffee available, if you knew where to look for it. A number of small cafes and shops continued to trade, sourcing and roasting high quality arabica beans. These outlets were typically run and frequented by immigrants (usually Arabs, Turks, Greeks and Italians), far from the mainstream.

All this began to change in the 1960s, with the post World War II ‘Baby Boomers’ coming into adulthood. Many of this generation were keen not to follow in their parents footsteps, preferring to act in a more bohemian way. For them, these cafes and shops were an ideal place to meet, read poetry, take drugs and experience alternative culture.

One such coffee shop in Berkeley (California) is widely credited as being the main inspiration on the emergence of the speciality coffee sector. Peet’s Coffee & Tea store, opened in 1966 by Alfred Peet (dubbed the ‘grandfather of speciality coffee’), enthused a number of its customers, who later became key players in the speciality sector. Peet, an immigrant from Alkmaar (Holland), had developed a distinctive style of roasting coffee from working in his family’s coffee and tea business. After emigrating to California, aged thirty-five, he opened his shop employing his artisan coffee roasting techniques to build a loyal customer base. Peet’s coffee was so loved that he even had his own set of groupies: the ‘Peetniks’.

Two of Peet’s most important customers (historically) were a couple of Seattle coffee lovers named Jerry Baldwin and Gordon Bowker. In 1971, after tasting Peet’s fine brews, they were inspired to open their own coffee shop back in Seattle called Starbucks. Starbucks opened as a bean-only-store, steadily building a loyal customer base during the 70s and early 80s through its fine arabicas and darker roasts.

In 1984, the director of retail operations and marketing, Howard Schultz, tried to persuade Baldwin and Bowker to open the first Starbucks coffeehouse. Schultz had just returned from a trip to Milan, where he had noticed the existence of coffeehouses on almost every block. These were not just places to enjoy great espresso coffee, but also served as meeting places. Schultz was keen to recreate this kind of coffeehouse in America, but Baldwin and Bowker rejected Schultz’s plans as they were unwilling to get into the restaurant business.

Undeterred, Schultz left Starbucks in 1985 to open his own coffeehouse, ‘Il Giornale’. Still using Starbucks coffee beans to make espresso drinks, Il Giornale proved extremely popular with the Seattle public. So popular in fact() that, in 1987, Schultz was able to buy Starbucks from Bowker and Schultz. Changing Il Giornale’s name to Starbucks, Schultz began to rapidly expand, opening over 1,000 stores in a decade.

The story of the first British speciality coffeehouse also involves Alfred Peet. In 1995, Scott and Ally Svenson wanted to open a coffeehouse in Covent Garden, London. Their background was in marketing and design and, even though they were originally from Seattle, they did not know much about coffee. This is why they approached Steven Macatonia and Jeremy Torz of Union Coffee Roasters. Steven and Jeremy had fallen in love with coffee while working at Peet’s in California. On their return home they decided to open their own roasting outlet and were soon supplying places such as the River Café, the Caprice, and the Ivy.

The Covent Garden coffeehouse, named the Seattle Coffee Company, was another big success and inevitably expansion soon followed. The rapid growth of the company caused increasing demand on Union Coffee Roasters, so the two companies decided to merge together. In 1998, after opening over 60 outlets throughout the UK, Starbucks came knocking at their door. They saw the acquisition of the Seattle Coffee Company as an ideal way to enter the UK market. Soon the Seattle Coffee Company was no more, with all its stores re-branded as Starbucks.

The popularity of coffeehouses has been phenomenal. Almost every high street in Britain has a least one coffeehouse now. Words such as espresso, cappuccino and café latte are commonplace. In fact the price of a café latte is now one of the products that the British government use to measure inflation. Market analysers believe that the success of the coffeehouse is not solely due to the coffee they serve, but the atmosphere in which it is served. Coffeehouses in Britain in the 1990s were a break from convention. In the consumerist landscape of the high-street, coffeehouses represented a place to relax. Customers were encouraged to take their time over their coffee; sit on big comfy sofas; offered the daily newspapers to read; allowed to idle the afternoon away watching the world go by. In other words, coffeehouses had returned to playing their original role in society, as they had done when they first arrived in Britain back in 17th Century.

The growth of these coffeehouses has helped to heighten the public’s awareness of the speciality coffee sector. Increasingly, individuals are looking to have a slice of the coffeehouse in their own home, investing in espresso makers and other coffee accessories. Coffee is now widely available from a multitude of origins, roasted to differing degrees and ground to your requirement. In short, the ‘Dark Age’ of coffee is well and truly over.
