Chinese Helped the Spread of Coffee?

Could coffee have become popular in the Arab world because China cut off its tea supply? The story goes that coffee became popular due to Chinese Admiral Cheng Ho’s introduction of tea to the Arabs in the early 1400s. When China cut off contact with the outside world, the Arabs replaced tea leaves, unobtainable in Arabia, with qat or coffee. However, this is little historical evidence for this story.

Mocha a Bustling Coffee Port

In 1606, when the first English trader visited Mocha, over thirty-five merchant ships from as far away as India were waiting to collect coffee bags. The city of Mocha was very crowded and bustling with activity, largely due to the coffee trade. Source: The Devil’s Cup by Stewart Lee Allen.

Bongas Slave Traders and Coffee Avenues

The Bongas were prominent slave traders, annually sending approximately seven thousand slaves to the Arabic markets in Harrar. Many of these slaves were Oromos, known for their habit of chewing coffee beans, who had been taken prisoner during conflicts. Interestingly, it was these captives who inadvertently introduced coffee beans to Harrar. Today, Ethiopian rangers report that the old paths used by the slaves are still lined with coffee trees, a living testament to the discarded remnants of their meals.

First Fair Trade Coffee

The first ‘fair trade‘ coffee. In 1973, Fair Trade Original (NLD) imported the first fairly traded coffee from Guatemala but the move to formally certify ‘fair-trade’ coffee began on 15 Nov 1988. On that date, Solidaridad – a Dutch Catholic aid organization working mainly in Latin America – created the Max Havelaar Foundation to benefit local farmers with plummeting world coffee prices.

Ethiopia the Origin of Coffee?

The origins of coffee are not definitively known, but the most widely accepted theory is that coffee originated in Ethiopia, not China or Arabia. From Ethiopia, the use of coffee spread to Egypt and Yemen. Source: The Devil’s Cup by Stewart Lee Allen.

First Coffee Drinks?

The origins of the first coffee drink are debatable, but ‘Kati’ and ‘Amertassa’ are strong contenders. Historically, Ethiopians have consumed coffee beans for ages. However, the earliest documented mention of a coffee-like beverage indicates it was made from the leaves of the coffee plant and was known in Arabic as ‘Kafta’. Some experts argue that this early coffee was brewed with leaves from the qat plant, which is narcotic. In contrast, around the early 1400s, the Arab mystic al-Dhabhani observed Ethiopians consuming ‘qahwa’, a liquid form of coffee. This suggests that Ethiopians might have been drinking a coffee leaf concoction known as the semi-mythical ‘Abyssinian Tea’. Adding raw beans to the brew appears to have originated later in southern Yemen, either by the Sufi mystic al-Shadhili from Mocha or by one of his followers. Source: The Devil’s Cup by Stewart Lee Allen.

First Known Coffee Lovers

The Oromos, the first known coffee enthusiast and nomadic inhabitants of the kingdom of Kefa, didn’t consume coffee the way we do today. Instead of drinking it, they consumed coffee by eating it. They would crush the coffee and mix it with fat, then shape this mixture into treats about the size of a golf ball. Source: The Devil’s Cup by Stewart Lee Allen.

Coffee, Kefa, and qahwa

The term ‘coffee’ is believed by some to have originated from ‘Kefa’, while others argue that it is derived from the Arabic word ‘qahwa’, which comes from the root ‘q-h-w-y’, meaning ‘to make something repugnant’. Initially, ‘qahwa’ was used to refer to wine, which was considered to make food repugnant. This term was later applied to coffee due to its ability to make sleep repugnant. Interestingly, Ethiopia stands out as the only country not using a term similar to ‘coffee’ for the beverage. Instead, they use the term ‘buna’, which translates to ‘bean’. Source: The Devil’s Cup by Stewart Lee Allen.

These facts delineate the historical significance of coffee, its roots in ancient cultures, and the sometimes contentious journey it has taken to become a global staple. They reflect the mystique surrounding its discovery and how its stimulating effects captivated the attention of various cultures, leading to its integration into religious and social customs.

Prostate Cancer

Men who drink six or more cups of coffee a day seem to have 20% less prostate cancer.

This coffee fact appears to be valid according to several studies. A study published in the Journal of the National Cancer Institute found that men who consumed six or more cups of coffee per day had an 18% lower risk of prostate cancer compared to men who did not drink coffee [1].

Similarly, a study from the Harvard School of Public Health found that men who consumed the most coffee (six or more cups daily) had nearly a 20% lower risk of developing any form of prostate cancer [2].

This finding is also supported by research from Baptist Health and WebMD, which both report that men who consumed six or more cups of coffee per day had a nearly 20% lower risk of developing prostate cancer [3][4].

A systematic review and meta-analysis published in BMJ Open also suggests that a higher intake of coffee may be associated with a lower risk of prostate cancer [7]. Therefore, the statement is supported by multiple scientific studies.

However, it’s important to note that these studies show an association, not a cause-and-effect relationship, and more research is needed to understand the underlying mechanisms. Another study also showed no causal effect between coffee and prostate cancer [8].

Coffee Psychopaths

People who drink black coffee are more likely to be psychopaths. Source: Quite Interesting (QI)

This statement is based on a study conducted by the University of Innsbruck in Austria, which found a correlation between a preference for bitter tastes, such as black coffee, and certain personality traits like psychopathy, sadism, narcissism, and aggression [2][4]. The study surveyed nearly 1,000 adults about their flavor preferences and administered four personality tests [2][4].

However, it’s important to note that this study does not definitively prove that people who drink black coffee are psychopaths. The correlation found in the study does not imply causation. The study found that these people had psychopathic tendencies but did not identify them as actual psychopaths [1]. Furthermore, the study found a general preference for bitter tastes, not just black coffee, was associated with these traits [6].

Moreover, some experts have criticized the study, arguing that the link between psychopathy and a general penchant for bitter things is weak and negligible compared to other, more well-established factors [6]. The research linking taste preferences to personality traits is still in its early stages, and evidence is generally scarce [6].

In conclusion, while the study suggests a possible correlation between a preference for black coffee and certain personality traits, it does not provide conclusive evidence that people who drink black coffee are more likely to be psychopaths. It’s also important to remember that psychopathy is a complex trait that falls along a continuum and cannot be determined solely based on one’s coffee preferences [6].

Coffee, frequently mentioned in Civil War soldiers’ diaries

In the diaries of Civil War soldiers, the word “coffee” appears more frequently than terms such as “war,” “slavery,” or “Lincoln.” This beverage was often the last comfort soldiers enjoyed before entering battle and the first sign of safety they encountered afterward. Coffee was a cherished luxury that bolstered morale, comforted, and gave soldiers the fortitude to continue their march [1].

A notable instance of coffee’s significance during the Civil War involves future President William McKinley. During the Battle of Antietam, known as the bloodiest single-day battle in American history, McKinley, then a commissary sergeant, bravely served coffee to soldiers amidst the fighting. This act of courage and care earned him the nickname “Coffee Bill” [2][6]. In recognition of his actions, a monument was dedicated to McKinley, highlighting his brave service of providing hot coffee and warm food to every man in his regiment under fire [4][6].

Coffee And Religion

coffee and religion

The influence of coffee in religion is a fascinating and multifaceted topic, tracing back centuries. Coffee’s introduction to various cultures often intersected with religious practices and beliefs, leading to a range of responses from acceptance to prohibition.

However, the introduction of coffee was not always met with approval. In some religious contexts, coffee faced opposition and was even banned temporarily.

The role of coffee in religion is not just historical but continues today. It facilitates social interactions in religious communities as a focal point for gathering and discussion. Many churches, mosques, and synagogues use coffee to foster community and conversation among their congregants.

The journey of coffee through various religious landscapes highlights its role as a catalyst for social interaction, spiritual practice, and even theological debate. Its widespread acceptance across different faiths underlines the universality of its appeal and its ability to transcend cultural and religious boundaries.

Coffee’s Legality in Islam

Coffee has religious implications, particularly in Islamic jurisprudence. The argument for keeping coffee legal was based on the Hanafi principle of al-ibaha al-asliya, which stipulates that whatever is not explicitly forbidden in the Koran is allowed. Coffee lovers pointed out that, although the cup did have psychological effects, so did garlic, and that the traditional Islamic definition of intoxication was “when one is incapable of distinguishing man from woman, or heaven from earth” Source: The Devil’s Cup by Stewart Lee Allen.

Jewish Communities Welcomed Coffee

In the Jewish community, coffee was quickly integrated into social and religious life. Rabbis debated its status in religious law, particularly in the context of fasting and dietary restrictions. Eventually, coffee was deemed permissible, and it played a role in social gatherings and religious ceremonies, such as the Passover Seder. Source: Project Muse

Sufi Religious Ceremonies

Coffee is believed to have been used in Sufi religious ceremonies in the holy city of Mecca around 1480. The Sufis used coffee as an intoxicant, passing the drink hand to hand from their sheykah, or priest, symbolizing its role as a sanctified intoxicant. The Sufis even had a term for the religious high associated with coffee, marqaha. The Devil’s Cup by Stewart Lee Allen.

The ‘Production and Trade’ category contains facts about coffee’s growth, distribution, and economic impact.

Coffee Trees Live up to 100 Years Old

Coffee plants can live up to 100 years but are most productive between the ages of 7 and 20 [3]. The tree of Coffea arabica will grow fruits after three to five years, producing for an average of 50 to 60 years, although up to 100 is possible [4]. The average lifespan of a coffee tree is often cited as around 20 years [1][2]. However, this can vary depending on the variety of the coffee tree and the conditions in which it is grown.

However, the claim that slower ripening leads to higher-quality coffee may not be accurate. While it’s true that the conditions under which coffee is grown can affect the quality of the beans, the relationship between ripening time and quality is complex and can be influenced by many factors, including the specific variety of coffee and the local climate.

How Coffee is Processed Determines Flavors

Different methods of processing coffee cherries, like washed, semi-washed, natural, and honey processing, result in different flavors and characteristics of the final product. Source: Coffee for Dummies by Major Cohen

A Coffee Berry May Contain Only One Seed

A typical coffee cherry contains two seeds (or beans), but sometimes, a cherry will develop with just one seed. When this happens, the single seed fills the cherry and develops into a round, pea-like shape, hence the name “peaberry”.

Peaberries are relatively rare, accounting for only about 5-10% of all coffee beans. They are often separated from regular beans and sold as a specialty product, as some believe they have a more concentrated flavor. Source: coffeehit

Four out of five Americans start their day with a cup of coffee. True or False?

This is more than half of the nation, but it is not as high as four out of five (or 80%). Therefore, while many Americans start their day with coffee, the exact figure is lower than stated in the claim.

13 Billion Coffee Trees In Brazil?

We estimate that there could be over 13 billion coffee trees in Brazil. How did we estimate this?

The total hectares dedicated to coffee in Brazil across the six states are:

  • Minas Gerais: 1,220,000 hectares
  • Espírito Santo: 433,000 hectares
  • São Paulo: 216,000 hectares
  • Bahia: 171,000 hectares
  • Rondônia: 95,000 hectares
  • Paraná: 49,000 hectares

The total land dedicated to coffee in Brazil is 2,184,000 hectares.

The density of coffee trees can vary based on the type of coffee plant and the farming techniques used. A common range is 2,500 to 10,000 trees per hectare. Let’s estimate a median value of 6,250 trees per hectare.

Multiply the total hectares by the average number of coffee trees per hectare and we get 13.65 billion coffee trees.
