You press a button, pour a kettle or open a can, and a few minutes later coffee is in your hands. What most people never see is how long that cup took to arrive.
It starts with a tree that makes you wait
A coffee tree begins producing cherries after roughly three years and only reaches full production at around five. Arabica needs almost nine months from flowering to harvest. So before a single bean is picked, someone has tended that tree through years of weather, pests and patience. aboutcoffeebunafr
The yield is smaller than most people expect. The average tree produces about 10 pounds of cherries a year, which is just 2 pounds of green, unprocessed beans. The "bean" is really a seed, and most cherries hold two of them pressed together. aboutcoffeecoffeereview
Why altitude and arabica go together
Arabica is the more delicate of the two main coffee species, and it rewards the right conditions. In Colombia, for example, coffee is grown between 1,200 and 2,200 metres, and higher altitude also means fewer pests. Slower ripening on cooler hillsides is a big part of why arabica develops the sweetness and complexity people look for in a good cup. pergamino
It is also the bigger share of the world's coffee. In the 2023/24 season the world produced 102.2 million bags of arabica, 57.41% of the total. The share moves around from year to year, and for 2025/26 it is projected to fall to 54% as robusta production grows. A coffee labelled 100% arabica means none of that robusta is in the bag. cropgptsafras
Picking, processing and the race against spoilage
Quality coffee is picked ripe, not stripped off the branch all at once. Selective picking means only ripe cherries are taken, one at a time by hand, and a skilled picker averages 100 to 200 pounds a day. Those are pounds of cherry, not finished coffee. cameronscoffee
Then the clock starts. Farmers process the cherries as quickly as possible to prevent spoilage, either drying them whole in the sun for several weeks, or de pulping them and soaking for 12 to 48 hours before drying. cameronscoffee
The hidden cost: water
A cup uses far more water than the 125ml in your cafetiere. Around 140 litres of water goes into growing the beans for a single cup. That figure comes from a 2007 academic study by Chapagain and Hoekstra and is an average, so it varies by origin and method. It is a useful reminder of why sustainable farming matters. eco-business
Specialty means scored, not just claimed
Coffee is graded by trained tasters through a process called cupping. Specialty coffee is arabica scoring 80 or more on the SCA's 100 point scale, assessed by certified Q graders against ten attributes including aroma, flavour, aftertaste, acidity, body, balance and sweetness. Most specialty coffees fall between 80 and 86 points, and a score of 90 or above is rare. An 84 sits firmly in the very good to excellent range, which is where our range lives. roasterstasteology
And then it reaches your cup
The UK now drinks approximately 98 million cups of coffee a day. Every one of them began with a tree, a farmer, a harvest and a long chain of people in between. britishcoffeeassociation
Why this matters to Siren Grounds
Our coffee comes through our Farm to Roaster partnership and is cupped at 81+ on the SCA scale, from specialty grade South American arabica. We believe you should know what is behind your cup: where it grew, who picked it, and how it was graded. A good cup is the end of a long story, and we think it is worth telling properly.
