Why ’42’ in rijo42?

The commercial coffee machines at rijo HQ have been in overdrive this week as a result of the cold weather. Our trusty Brasil bean to cup coffee machines have never missed a beat though, delivering freshly ground luxury coffees for staff and visitors to enjoy.

Whilst preparing a latte for a shivering delivery driver earlier today, I was asked what the ‘42’ in rijo42 represents. The meaning of ‘42’ in rijo42 is incredibly simple; it takes 42 coffee beans to make the perfect espresso; rijo is a coffee company, espresso is the ultimate form of coffee…need I go on? The ‘42’ question prompted the decision to share some further facts about coffee in tonight’s post, such as Fact #1: A cup of black coffee with nothing added contains zero calories. Fact #2: Espresso contains 2/3 less caffeine than a regular cup of coffee. Fact #3: Robusta coffee contains double the caffeine content of Arabica. Here’s a few more interesting facts about your beloved daily caffeine hit…

Coffee is the second most traded product in the world after oil with global coffee production at around eight million tonnes per year. An estimated 1.6 billion cups of coffee are consumed around the globe every day. Global coffee consumption has doubled over the last 40 years meaning coffee production is projected to rise to over 9 million tonnes by 2019. There are 65 countries which grow coffee and they are all along the equator. Brazil is the biggest coffee producing nation by far, accounting for around 32.4% of worldwide production.

There are many species of coffee tree in the world however there are only two which are cultivated for commercial use, Arabica and Robusta. A coffee tree’s lifespan can be anywhere between 50 and 70 years but some live up to the ripe old age of 100. The average tree takes around five years to reach maturity. Depending on rainfall, a coffee tree can flower up to eight times a year and when in bloom will be covered with around 30,000 flowers. After 24-36 hours, the flowers develop into fruits – cherries. Coffee cherries turn from yellow to orange in colour and then 6-8 months after flowering turn bright red. A coffee cherry normally contains two beans; a cherry containing three beans is deemed to be good luck. The average yield from one coffee tree equates to around 1 kilo of roasted coffee.

Coffee sacks are usually made of Hessian and weigh around 132 lbs when filled with green coffee beans. It takes around 600,000 green coffee beans to fill one Hessian sack. Green coffee is the term used for coffee beans which have been picked, processed and dried but have not yet been roasted.

The coffee roasting process usually takes between 11-13 minutes using temperatures of around 288°C. The green coffee beans turn yellow at first and are described as having the aroma of popcorn. At around the 8th minute of roasting, the beans ‘pop’, double in size and begin to turn brown due to the coffee essence (inner oils) emerging. The aromas in coffee develop in the 10th minute of the roasting process through a chemical reaction known as Pyrolysis, a direct result of the heat and coffee essence combining. Both green coffee and roasted coffee are exported worldwide in huge quanities. Brazil is the largest exporter with 31% of global coffee exports.

In the coffee year 2011/2012, coffee exports reached a record of 109.4 million bags, an increase of 4.5% based on the previous year. The total value of coffee exports in 2011/2012 was an estimated £14.7bn.

Coffee is the second most popular drink in the world after water and as such the thriving coffee industry provides a living to over 125 million people worldwide.
