PREPARATION OF THE UNIVERSAL BEVERAGE

The coffee drink has had a curious evolution. It began, not as a drink, but as a food ration. Its first use as a drink was as a kind of wine. Civilization knew it first as a medicine. At one stage of its development, before it became generally accepted as a liquid refreshment, the berries found favor as a confection. As a beverage, its use probably dates back about six hundred years.

The protein and fat content, that is, the food value, of coffee, so far as civilized man is concerned, is an absolute waste. The only constituents that are of value are those that are water soluble, and can be extracted readily with hot water. When coffee is properly made, as by the drip method, either by percolation or filtration, the ground coffee comes in contact with the hot water for only a few minutes; so the major portion of the protein, which is not only practically insoluble, but coagulates on heating, remains in the unused part of the coffee, the grounds. The coffee bean contains a large percent of protein--fourteen percent. By comparing this figure with twenty-one percent of protein in peas, twenty-three percent in lentils, twenty-six percent in beans, twenty-four percent in peanuts, about eleven percent in wheat flour, and less than nine percent in white bread, we learn how much of this valuable food stuff is lost with the coffee grounds[373].

Though civilized man (excepting the inhabitants of the Isle de Groix off the coast of Brittany) does not use this protein content of coffee, in certain parts of Africa it has been put to use in a very ingenious and effective manner "from time immemorial" down to the present day. James Bruce, the Scottish explorer, in his travels to discover the source of the Nile in 1768-73, found that this curious use of the coffee bean had been known for centuries. He brought back accounts and specimens of its use as a food in the shape of balls made of grease mixed with roasted coffee finely ground between stones.

Other writers have told how the Galla, a wandering tribe of Africa--and like most wandering tribes, a warlike one--find it necessary to carry concentrated food on their long marches. Before starting on their marauding excursions, each warrior equips himself with a number of food balls. These prototypes of the modern food tablet are about the size of a billiard ball, and consist of pulverized coffee held in shape with fat. One ball constitutes a day's ration; and although civilized man might find it unpalatable, from the purely physiological standpoint it is not only a concentrated and efficient food, but it also has the additional advantage of containing a valuable stimulant in the caffein content which spurs the warrior on to maximum effort. And so the savage in the African jungle has apparently solved two problems; the utilization of coffee's protein, and the production of a concentrated food.

Further research shows that perhaps as early as 800 A.D. this practise started by crushing the whole ripe berries, beans and hulls, in mortars, mixing them with fats, and rounding them into food balls. Later, the dried berries were so used. The inhabitants of Groix, also, thrive on a diet that includes roasted coffee beans.

About 900, a kind of aromatic wine was made in Africa from the fermented juice of the hulls and pulp of the ripe berries[374].

Payen says that the first coffee drinkers did not think of roasting but, impressed by the aroma of the dried beans, they put them in cold water and drank the liquor saturated with their aromatic principles. Crushing the raw beans and hulls, and steeping them in water, was a later improvement.

It appears that boiled coffee (the name is anathema today) was invented about the year 1000 A.D. Even then, the beans were not roasted. We read of their use in medicine in the form of a decoction. The dried fruit, beans and hulls, were boiled in stone or clay cauldrons. The custom of using the sun-dried hulls, without roasting, still exists in Africa, Arabia, and parts of southern Asia. The natives of Sumatra neglect the fruit of the coffee tree and use the leaves to make a tea-like infusion. Jardin relates that in Guiana an agreeable tea is made by drying the young buds of the coffee tree, and rolling them on a copper plate slightly heated. In Uganda, the natives eat the raw berries; from bananas and coffee they make also a sweet, savory drink which is called menghai.

About 1200, the practise was common of making a decoction from the dried hulls alone. There followed the discovery that roasting improved the flavor. Even today, this drink known as Sultan or Sultana coffee, café à la sultane, or kisher, continues in favor in Arabia. Credit for the invention of this beverage has been wrongfully given by various French writers to Doctor Andry, director of the Faculty of Medicine in Paris. Dr. Andry had his own recipe for making café à la sultane, which was to boil the coffee hulls for half an hour. This gave a lemon-colored liquid which was drunk with a little sugar.

The Oriental procedure was to toast the hulls in an earthenware pot over a charcoal fire, mixing in with them a small quantity of the silver skins, and turning them over until they were slightly parched. The hulls and silver skins, in proportions of four to one, were then thrown into boiling water and well boiled again for at least a half-hour. The color of the drink had some resemblance to the best English beer, La Roque assures us, and it required no sweetening, "there being no bitterness to correct." This was still the coffee drink of the court of Yemen, and of people of distinction in the Levant, when La Roque and his fellow-travelers made their celebrated voyage to Arabia the Happy in 1711-13.

Some time in the thirteenth century, the practise began of roasting the dried beans, after the hulling process. This was done first in crude stone and earthenware trays, and later on metal plates, as described in chapter XXXIV. A liquor was made from boiling the whole roasted beans. The next step was to pound the roasted beans to a powder with a mortar and pestle; and the decoction was then made by throwing the powder into boiling water, the drink being swallowed in its entirety, grounds and all. It was a decoction for the next four centuries.

When the long-handled Arabian metal boiler made its appearance in the early part of the sixteenth century, the method of preparation and service had much improved. The Arabs and the Turks had made it a social adjunct, and its use was no longer confined to the physicians and the churchmen. It had become a stimulating refreshment for all the people; and at the same time, the Arabians and the Turks had developed a coffee ceremony for the higher classes which was quite as wonderful as the tea ceremony of Japan.

The common early method of preparation throughout the Levant was to steep the powder in water for a day, to boil the liquor half away, to strain it, and to keep it in earthen pots for use as wanted. In the sixteenth century, the small coffee boiler, or ibrik, caused the practise to be more of an instantaneous affair. The coffee was ground, and the powder was dropped into the boiling water, to be withdrawn from the fire several times as it boiled up to the rim. While still boiling, cinnamon and cloves were sometimes added before pouring the liquid off into the findjans, or little china cups, to be served with the addition of a drop of essence of amber. Later, the Turks added sugar during the boiling process.

From the first simple uncovered ibrik there was developed, about the middle of the seventeenth century, a larger-size covered coffee boiler, the forerunner of the modern combination brewing and serving pot. This was a copper-plated kettle patterned after the oriental ewer with a broad base, bulbous body, and narrow neck. After having poured into it one and a half times as much water as the dish (cup) in which the drink was to be served would hold, the pot was placed on a lively fire. When the water boiled, the powdered coffee was tossed into the pot; and, as the liquid boiled up, it was taken from the fire and returned, probably a dozen times. Then the pot was placed in hot ashes to permit the grounds to settle. This done, the drink was served. Dufour, describing this process as practised in Turkey and Arabia, says:

One ought not to drink coffee, but suck it in as hot as one can. In order not to be burned, it is not necessary to place the tongue in the cup but hold the edge against the tongue with the lips above and below it, forcing it so little that the edges do not bear down, and then suck in; that is to say, swallow it sip by sip. If one is so delicate he can not stand the bitterness, he can temper it with sugar. It is a mistake to stir the coffee in the pot, the grounds being worth nothing. In the Levant it is only the scum of the people who swallow the grounds.

La Roque says:

The Arabians, when they take their coffee off the fire, immediately wrap the vessel in a wet cloth which fines the liquor instantly, makes it cream at the top and occasion a more pungent steam, which they take great pleasure in snuffing up as the coffee is pouring into the cups. They, like all other nations of the East, drink their coffee without sugar.

Some of the Orientals afterward modified the early coffee-making procedure by pouring the boiling water on the powdered coffee in the serving cups. They thus obtained "a foaming and perfumed beverage," says Jardin, "to which we (the French) could not accustom ourselves because of the powder which remains in suspension. Nevertheless, clarified coffee may be obtained in the Orient. In Mecca, in order to filter it, they strain it through stopples of dried herbs, put into the opening of a jar."

Sugar seems to have been introduced into coffee in Cairo about 1625. Veslingius records that the coffee drinkers in Cairo's three thousand coffee houses "did begin to put sugar in their coffee to correct the bitterness of it", and that "others made sugar plums of the coffee berries". This coffee confection later appeared in Paris, and about the same time (1700) at Montpellier was introduced a coffee water, "a sort of rosa-folis of an agreeable scent that has somewhat of the smell of coffee roasted." These novelties, however, were designed to please only "the most nice lovers of coffee"; for ennui and boredom demanded new sensations then as now.

Boiling continued the favorite method of preparing the beverage until well into the eighteenth century. Meanwhile, we learn from English references that it was the custom to buy the beans of apothecaries, to dry them in an oven, or to roast them in an old pudding dish or frying pan before pounding them to a powder with mortar and pestle, to force the powder through a lawn sieve, and then to boil it with spring water for a quarter of an hour. The following recipe from a rare book published in London, 1662, details the manner of making coffee in the seventeenth century:

COFFEE MAKING IN 1662

To make the drink that is now much used called coffee.

The coffee-berries are to be bought at any Druggist, about three shillings the pound; take what quantity you please, and over a charcoal fire, in an old pudding-pan or frying-pan, keep them always stirring until they be quite black, and when you crack one with your teeth that it is black within as it is without; yet if you exceed, then do you waste the Oyl, which only makes the drink; and if less, then will it not deliver its Oyl, which must make the drink; and if you should continue fire till it be white, it will then make no coffee, but only give you its salt. The Berry prepared as above, beaten and forced through a Lawn Sive, is then fit for use.

Take clean water, and boil one-third of it away what quantity soever it be, and it is fit for use. Take one quart of this prepared Water, put in it one ounce of your prepared coffee, and boil it gently one-quarter of an hour, and it is fit for your use; drink one-quarter of a pint as hot as you can sip it.

In England, about this time, the coffee drink was not infrequently mixed with sugar candy, and even with mustard. In the coffee houses, however, it was usually served black, without sugar or milk.

About 1660, Nieuhoff, the Dutch ambassador to China, was the first to make a trial of coffee with milk in imitation of tea with milk. In 1685, Sieur Monin, a celebrated doctor of Grenoble, France, first recommended café au lait as a medicine. He prepared it thus: Place on the fire a bowl of milk. When it begins to rise, throw in to it a bowl of powdered coffee, a bowl of moist sugar, and let it boil for some time.

We read that in 1669 "coffee in France was a hot black decoction of muddy grounds thickened with syrup."

Angelo Rambaldi in his Ambrosia Arabica thus describes coffee making in Italy and other European countries in 1691:

DESCRIPTION OF THE VASE FOR MAKING THE DECOCTION, DOSE OF POWDER AND OF THE WATER NECESSARY AND TIME OF BOILING IT.

Two such vessels having a large paunch to reach the fire, two others with long necks and narrow, with a cover to restrain their spirituous and volatile particles which when thrown off by the heat are easily lost. These vessels are called Ibriq in Arabia. They are made of copper--coated with white outside and inside. We, who do not possess the art of making them should select an earth vitriate, sulphate of copper, or any other material adapted for kitchen ware: it might even be of silver.

The quantity of water and powder has no certain rule, by reason of the difference of our nature and tastes, and each one after some experience will use his own judgment to adjust it to his desire and liking.

Maronita infused two ounces of powder in three litres of water. Cotovico in his voyage to Jerusalem affirms that he has observed six ounces of the former to 20 litres of the latter, boiled until it was reduced to half the quantity. Thévenot asserts that the Turks in three cups of water are contented with a good spoonful of powder. I have observed however that in Africa, France and England, into about six ounces of water (which with them is one cup) a dram of the powder is infused and this agrees with my taste--but I have wished at times to change the dose.

Others put the water into the vase and when it begins to boil add the powder, but because it is full of spirit at the first contact with the heat it rises and boils over the edge of the vase. Take it away from the fire till the boiling ceases, then put it on the fire again and let it stay a short time boiling with the cover on: Stand it on warm ashes until it settles, after which slowly pour a little of the decoction into an earthen vessel, or one of porcelain or any other kind, as hot as can be borne, and drink a sip; if it pleases your taste, add a portion of cardamom, cloves, nutmeg or cinnamon, and dissolve a little sugar in the water; yet because these substances will alter the taste of this simple, they are not prized by many experts.

Modern Arabia, Bassa, Turkey, the Great Orient, those who are travelling or in the army, infuse the powder in cold water, and then boiling it as directed above, bear witness to its efficacy. All times are opportune to take this salutary drink (beverage). Among the Turks are those who take it even by night, nor is there a business meeting or conversation, where coffee is not taken. Among the Great it would be accounted an incivility, if with smoke, coffee were not offered: and no one in the day is ashamed to frequent the bazaars where it is sold. When I was in London, that city of three million people, there were taverns for its special use. It is a great stimulant. The sober take it to invigorate the stomach. The scrofulous hated it because they thought it stirred up the bile on an empty stomach--but experience proving the contrary enjoy it as much as others.

In 1702, coffee in the American colonies was being used as a refreshment between meals, "like spirituous liquors."

It was in 1711 that the infusion idea in coffee making appeared in France. It came in the form of a fustian (cloth) bag which contained the ground coffee in the coffee maker, and the boiling water was poured over it. This was a decided French novelty, but it made slow headway in England and America, where some people were still boiling the whole roasted beans and drinking the liquor.

In England, as early as 1722, there arose a conscientious objector to boiled coffee in the person of Humphrey Broadbent, a coffee merchant who wrote a treatise on the True Way of Preparing and Making Coffee[375], in which he condemned the "silly" practise of making coffee by "boiling an ounce of the powder in a quart of water," then common in the London coffee houses, and urging the infusion method. He favored the following procedure:

Put the quantity of powder you intend, into your pot (which should be either of stone, or silver, being much better than tin or copper, which takes from it much of its flavour and goodness) then pour boiling-hot water upon the aforesaid powder, and let it stand to infuse five minutes before the fire. This is an excellent way, and far exceeds the common one of boiling, but whether you prepare it by boiling or this way, it will sometimes remain thick and troubled, after it is made, except you pour in a spoonful or two of cold water, which immediately precipitates the more heavy parts at the bottom, and makes it clear enough for drinking.

Some, make coffee with spring water, but it is not so good as river, or Thames-water, because the former makes it hard, and distasteful, and the other makes it smooth and pleasant, lying soft on the stomach. If you have a desire to make good coffee in your families, I cannot conceive how you can put less than two ounces of powder to a quart, or one ounce to a pint of water; some put two ounces and a quarter.

By 1760, the decoction, or boiling, method in France had been generally replaced by the infusion, or steeping, method.

In 1763, Donmartin, a tinsmith of St. Bendit, France, invented a coffee pot, the inside of which was "filled by a fine sack put in its entirety," and which had a tap to draw the coffee. Many inventions to make coffee sans ebullition (without boiling) appeared in France about this time; but it was not until 1800 that De Belloy's pot, employing the original French drip method, appeared, signaling another step forward in coffee making--percolation.

De Belloy and Count Rumford

De Belloy's pot was probably made of iron or tin, afterward of porcelain; and it has served as a model for all the percolation devices that followed it for the next hundred years. It does not seem to have been patented, and not much is known of the inventor. About this period, it was the common practise in England to boil coffee in the good old-fashioned way, and to "fine" (clarify) it with isinglass. This moved Count Rumford (Benjamin Thompson), an American-British scientist, then living in Paris, to make a study of scientific coffee-making, and to produce an improved drip device known as Rumford's percolator. He has been generally credited with the invention of the percolator; but, as pointed out in a previous chapter, this honor seems to be De Belloy's and not Rumford's.

Count Rumford embodied his observations and conclusions in a verbose essay entitled Of the excellent qualities of coffee and the art of making it in the highest perfection, published in London in 1812. In this treatise he describes and illustrates the Rumford percolator.

Brillat-Savarin, the famous French gastronomist, who also wrote on coffee in his VIme Meditation, said of the De Belloy pot:

I have tried, in the course of time, all methods and of all those which have been suggested to me up to today (1825) and with a full knowledge of the matter in hand. I prefer the De Belloy method, which consists of pouring the boiling water upon the coffee which has been placed in the vessel of porcelain or silver, pierced with very small holes. I have attempted to make coffee in a boiler at high pressure, but I have had as a result a coffee full of extracts and bitterness which would scrape the throat of a Cossack.

Brillat-Savarin had something also to say on the subject of grinding coffee, his conclusion being that it was "better to pound the coffee than to grind it."

He refers to M. Du Belloy, archbishop of Paris, "who loved good things and was quite an epicure," and says that Napoleon showed him deference and respect. This may have been Jean Baptiste De Belloy, who, according to Didot, was born in 1709 and died in 1808, and, it is thought likely, was the inventor of the De Belloy pot.

Count Rumford was born in Woburn, Mass., in 1753. He was apprenticed to a storekeeper in Salem in 1766. He became an object of distrust among the friends of the cause of American freedom: and, on the evacuation of Boston by the Royal troops in 1776, he was selected by Governor Wentworth of New Hampshire to carry dispatches to England. He left England in 1802, and resided in France from 1804 until his death in 1814. In 1772, he had married, or rather, as he put it, he was married by, a wealthy widow, the daughter of a highly respectable minister and one of the first settlers at Rumford, now called Concord, New Hampshire. It was from this town that he took his title of Rumford when he was created a Count of the Holy Roman Empire in 1791. His first wife having died, he married in Paris, the wealthy widow of the celebrated chemist, Lavoisier; and with her he lived an extremely uncomfortable life until they agreed to separate.

In his essay on coffee and coffee making, Count Rumford gives us a good pen picture of the preparation of the beverage in England at the beginning of the nineteenth century. He says:

Coffee is first roasted in an iron pan, or in a hollow cylinder, made of sheet iron, over a brisk fire; and when, from the colour of the grain, and the peculiar fragrance which it acquires in this process, it is judged to be sufficiently roasted, it is taken from the fire, and suffered to cool. When cold it is pounded in a mortar; or ground in a hand-mill to a coarse powder, and preserved for use.

Formerly, the ground Coffee being put into a coffee-pot, with a sufficient quantity of water, the coffee-pot was put over the fire, and after the water had been made to boil a certain time, the coffee-pot was removed from the fire, and the grounds having had time to settle, or having been fined down with isinglass, the clear liquor was poured off, and immediately served up in cups.

Count Rumford thought it a mistake to agitate the coffee powder in the brewing process, and in this he agreed with De Belloy. His improvement on the latter's pot is described in chapter XXXIV. He was a coffee connoisseur; and as such was one of the first to advocate the use of cream as well as sugar for making an ideal cup of the beverage. He refers, though not by name, to De Belloy's percolation method and says, "Its usefulness is now universally acknowledged."
