Coffee

The by-products of coffee processing are mainly coffee pulp, parchment husks and coffee husks. The main environmentally sustainable alternative uses include soil conditioner, fertilizer, mulch, animal feed, alcohol, bio gas, charcoal, heat energy, wax, and acids.

Coffee chaff from coffee roasting and spent coffee grounds from coffee manufacturing can also be used as CO2-neutral fuels. Spent coffee grounds from soluble coffee production can be burned as renewable fuel which replaces or reduces fossil fuel use for other production stages.

Four common sustainable coffee by-products include the following,

Composting

• Coffee pulp is a rich source of nutrients: 0.5% nitrogen; 0.15% phosphorus, and 0.5% potassium.
• Coffee pulp can be treated and used as organic fertilizer.
• Usually the coffee pulp is placed on piles and left to compost for about 3 to 12 months.
• During that time, coffee pulp turns into rich, black humus excellent for composting.
• Using organic fertilizers improves soil conditions and increases agricultural yield.
• Farmers save money otherwise spent buying inorganic fertilizers.

Mushroom planting soil

• Coffee pulp can also be used as planting soil for mushroom production.
• When used for this purpose, the coffee pulp is fermented for about two days.
• The coffee pulp is then pasteurized with hot water, drained, dried and mixed with mushroom spores.
• Next, the mixture is put in plastic bags with holes where the mushrooms develop for about 3 to 4 weeks.
• When the mushrooms grow out of the holes, they are collected.
• One bag allows for about 2 to 3 mushroom harvests.
• The fresh mushrooms are for table consumption or they can be dried for sale.
• The income from mushroom growing can be significant for the farmers who do this.

Animal feed supplement

• Coffee pulp is very rich in nutrients.
• Coffee pulp can be dried and used in animal feed.
• The pulp needs to be treated as quickly as possible to prevent the development of fungi.
• Usually, coffee pulp is treated with calcium hydroxide and dried under pressure.
• Another way to dry pulp, in the absence of industrial equipment, is to mix the coffee pulp with sugar cane molasses or other inorganic substances before storing the mix in silos.
• The resulting silage is available for use after 3 weeks and can remain stored for up to 18 months.
• The use of coffee pulp for this by-product appears to offer limited value because the cost of processing the pulp can exceed the gain derived from its use.
• The research on the effects of caffeine, potassium and other natural chemicals in the pulp on the health of animals is ongoing and will be influential for the future of this by-product.

Energy source for heat exchangers of coffee driers

• The most energy consuming step in coffee processing is drying.
• Sun drying is very common and offers many benefits but has drawbacks as well.
• Sun drying conserves energy, minimizes the use of fossil fuels and reduces costs.
• However, parchment coffee can be contaminated with dust and dirt during the sun drying process.
• Rainstorms happen without warning and are a challenge for farmers to prevent bean re-wetting which can promote bacterial infections and moldy growth.
• Because sun drying is time intensive, many coffee processors choose mechanical drying. The downside is that the cost to operate mechanical dryers is high and can cut down on margins.
• Using coffee parchment husks as the energy source for burners for heat exchangers of coffee driers is both a great environmentally friendly waste-recycling and energy-saving solution.

With international markets changing and the economic pressures mounting everywhere, crops such as coffee require innovative thinking to improve efficiency, cost effectiveness, quality and competitiveness. Sustainable coffee by-product development will continue to be a fast growing and important field of research.

Where did coffee originate? Coffee lovers around the world today may be numbering in the millions, but only a small number could be fully aware on the beginnings of this well-loved beverage. The history of coffee is definitely as rich as its flavor, spanning numerous centuries and dating as far back as 6th century A.D.

The oldest coffee legend

In the 6th century AD, farmers from Yemen were already growing coffee cherries. According to legend, a goat herder in Ethiopia was bewildered to discover that his goats were showing inexplicable energy after consuming a particular kind of cherries. After this goat herder tried the berries for himself and found that he too felt a surge of energy, Muslims discovered a way to extract the brew from the cherries, transforming the beans into a heady beverage. Thus, coffee became a secret beverage of the Muslims for a while, revitalizing them even during lengthy periods of worship. When 900 AD came round, coffee was already commonplace in the entire region of Arabia. From this period until 1500 AD, coffee farming practices were still a well-kept secret, although coffee beans were already exported to other places.

Coffee invasion in Europe

Before long however, Europeans found a way to bring coffee seedlings into their own lands. By 1615, merchants from Venice were able to bootleg a coffee plant out of the Yemen borders and into Europe. This time, coffee was used for its therapeutic purposes, being sold both as a drink and as a health remedy. When the Dutch got hold of the Ethiopian territory, they were able to bring coffee plants into Holland.

When it was discovered that Holland’s climate was not conducive to coffee farming, the Dutch brought the plants to other regions. When the first coffee shop opened its doors to the public in Oxford, England by the year 1650, women were forbidden to enter the shops. It was only three years later, when a teahouse was opened, that women found a place to converge.

The love story behind coffee Arabica

A Brazilian coast guard officer found two things he loved when he visited Cayenne in French Guyana in 1727: one, the coffee and two, the Governor’s wife. It was this affection that led him to acquire a few seeds which he took back to Brazil, initiating the Arabica coffee variety production in the country. Brazil eventually became the world’s largest coffee producer in 1800.

Afterwards, coffee traveled from country to country, spreading its popularity as a principal beverage of choice. The British introduced coffee to Jamaica in 1730. In 1774, Americans expressed a predilection for coffee during the Boston Tea Party, as a sign that they are replacing tea with coffee, due to the exorbitant taxes levied on tea trading. Costa Rica acquired coffee from Cuba, and this eventually spread to Mexico. The Island of Martinique cultivated coffee in the 1700s and Hawaii in 1825.

Present day coffee and coffee houses

Coffee houses are popular in Arabia; however they are as popular in Europe as well. From the 1600′s to the mid 1900s, coffee shops had already proliferated in Paris, reaching to approximately 3,000 in number. Presently, coffee is second to oil in terms of the most traded commodity worldwide.

Did you know that the coffee plant actually grows into a tree? The coffee tree is an evergreen tree. Its broad leaves are a very shiny green with pointed ends that are sleekly reminiscent of arrowheads. Their leaves grow in pairs one on each side of their long thin branches as they flower and seed from the base of each pair of leaves growing along the stems or branches. Their tiny blooms flower into five petals with yellow stamen, as the seedpods progress into berry like cases for the seed. Inside each seed, two beans are usually found these beans are what are used to make coffee. The berries of the coffee plant can display as green in unripe berries, red in ripe berries and black of over ripened berries. The coffee plant can be rooted from cuttings as well as grown from seed and thrives best in shaded areas.

The coffee plant is native to Ethiopia then transported to Yemen of Africa. There these coffee beans were chewed raw for the extra energy that they provided the people. In Yemen Europeans found the plant as it was taken to Europe to be transplanted there. Arabians first made a drink with the green coffee beans however; by not having been roasted, the drink did not offer the brunette russet flavor of coffee, as we know it to be. The idea to roast the coffee bean before boiling it is believed to enter the picture back in the 1400s.

From Europe, the Venetian mercantile decided that coffee should be introduced to the wealthy people there and charged outrageous prices for the coffee that they purchased. Although it was suggested that coffee be banned it was however baptized by a pope of that time, coffee then gains great popularity as a good hearty drink. At that time while being introduced to the French, they upheld the brilliant Arabians for being so ingenious to have introduced the world to the strong drink of coffee and opened the first coffee house in Paris. Coffee houses have flourished since that time. Eventually, coffee made its rounds into Austria and Poland.

Introduced in the seventeen hundreds, to the new world by aid of colonial officials, coffee came to America as a high value cash crop and is today only second to oil, as a valuable trade commodity. Billions of dollars every year are in used in spending for the purchase of coffee, the world round. While a bit later the Boston Tea Party called for drinking coffee an American patriotic duty. Although the ruler of Prussia attempted to block the imports of coffee, the public outcry of injustice turned these thoughts of this around.

The year of 1886 found Maxwell House coffee to be named after a hotel in which the drink was served. The nineteen hundreds saw the introduction of the Hills Brothers packing roast coffee into tins, which were vacuum-sealed, thus bringing about the end of coffee mills and local roasting shops. The American soldiers of WWII were issued instant Maxwell House coffee in their kits of ration, while in America the widespread issue of hoarding led the coffee to be rationed.

As for coffee, Johann Sebastian Bach said it best in 1732 within his lyrical gist of the Coffee Cantata, Mm! how sweet the coffee tastes, more delicious than a thousand kisses, mellower than muscatel wine.

Coffee direct from the roaster, or coffee grower, is really the way to enjoy your next cup of coffee. It is impossible to really know what coffee’s true taste is if you are constantly buying the already ground coffee which has been sitting in cans, on shelves, for weeks or even months.

The joy of coffee is not just the rush from the caffeine, but in the partaking of the aroma, the rich color, the taste of the first sip, and the pleasure from it. Drinking coffee is an experience much like drinking fine wine or smoking a truly good cigar.

Getting coffee direct from the roaster ensures the maximum of flavor and freshness. Coffee is at the ultimate of flavor immediately after it is roasted. When coffee is roasted they are then in a race against time as they slowly, but surely, begin to lose its fresh taste. If you really enjoy your coffee then this is the time when you want to buy it.

Enjoying Your Coffee The Right Way! Coffee is an art. There is a right, and a wrong, way to brew the perfect cup of coffee. If you’re willing to go out and buy good coffee, then you should prepare it the right way. First off, don’t buy already ground coffee. Coffee direct from the roasters should always be in bean form. The freshness and flavor are still there. Once the air hits them, it begins to diminish the quality, and over a short period of time coffee loses it’s boldness.

When grinding your coffee beans make sure that you are grinding the exact amount you will be using. Any extra is really useless as it will lose the aroma and flavor quickly. Sure, it will still taste like coffee, but not the way coffee should be. Spoon the coffee into your brewer of choice and let it brew.

Brewing coffee is also something you want to take into consideration with your coffee direct beans. Some machines get too hot and burn your coffee making it a waste. High end machines, while great, fast, and keep coffee at a good temperature, also have a high price tag. You can easily spend up to $300 to $400 on a high quality coffee machine. One of the simplest, and cheapest, ways to brew fresh ground coffee beans is with a coffee press. A coffee press is simple a jar with a screen on the top, a plunger and a tube. You simply place the coffee on the bottom of the jar, add hot water, let it brew for 4 minutes, and plunge the great tasting coffee right into your cup.

Coffee direct from the roaster should also be bought in smaller quantities. As stated already, coffee begins to lose it’s flavor through time.

Instead of having a large can of coffee that will take you three to four weeks to go through, buy small 8 oz. packages of beans directly from the roaster.

Many online companies that sell directly from roasters make small packages available so it is quite easy to get a week’s supply of fresh coffee beans. Since time is of the essence, then spending some time researching for a direct seller near you will reap tremendous rewards. Most online coffee direct sellers are located in places where UPS can deliver your coffee the next day ensuring you of great coffee every time you order it.

If you live near a farmer, or roaster, then buying it yourself will also save delivery time and you have a steady supply of fresh, flavorful coffee within driving distance of your home.

Buying coffee direct from roasters or growers is a great way to truly enjoy coffee the way it should be.

Coffee lovers will tell you that the best coffee comes from beans grounded immediately before the coffee is brewed. Old Time coffee drinkers know this by heart. That’s why No kitchen is complete without a coffee grinder. Waking up in the morning and grinding up a fresh batch of coffee beans and throwing it into the coffee maker and then anticipating that first sip of fresh hot coffee! Now that is the good life!

What Makes a Great Coffee Grinder?

When it comes to coffee grinders, there to basic types. One is called burr grinders and the other is called blade grinders. The difference between these two is basically how the beans are processed. Blade coffee grinders use a spinning blade to grind up the coffee beans. Burr grinders use burrs to grind up coffee beans. Burrs resemble plates with gears on them. One of the burrs is stationary, while the other one spins and grinds up the coffee beans.

When trying to make a great cup of coffee, one has to keep a couple things in mind. The taste of coffee will be affected by heat and uniformity. What this means is, heat is undesirable in a coffee grinder because it damages the coffee beans. The process of grinding coffee is relatively violent, because both blade and burr grinders in produce some heat. And of course, the faster the grinding mechanism runs; the more heat is being generated. Even finer grinds generate heat because of the extra time it takes to grind the coffee beans.

For those who are concerned about the quality of their coffee, one can purchase a low- speed burr grinder. A low speed burr will be more expensive. As well it will take longer to grind the coffee beans. But coffee purists will swear by these coffee grinders as the only way to go for a perfect cup of coffee.

Another very important factor is the uniformity of the grind. With the brewing process, the water spends a certain amount of time passing over the grinds. The uniform grinds are much more efficient at imparting flavor to the water. At first glance, the average coffee drinker may not be able to distinguish coffee that was grinded from a blade grinder vs. a burr grinder. But, to a coffee purist, they will notice the difference. The blade grinder is not very good at creating a uniform grind. However, with burr grinders, they produce an exceptional uniform grind resulting in a much tastier cup of coffee.

Quite frankly, it’s a no brainer when it comes to selecting a coffee grinder. The burr grinder is really the only way to go. However, some of the higher end models can cost several hundred dollars, thus putting them out of reach for some of the coffee lovers. However, this doesn’t mean that a small budget will always get a poor coffee grinder. Best to do a search online for burr coffee grinders. One can pick up a very nice coffee grinder for under hundred dollars. The selection is almost endless. Most coffee lovers consider a coffee grinder to be an investment and not an expense. After all, who can put the dollar value on a fantastic cup of coffee each and every morning? Yes, it is the good life!
