Background
Coffee Knowledge
The background that ties the index together: where coffee grows, how the plant works, who produces the most, and how specialty coffee is judged.
These entries cover the big picture behind every origin and variety in the index: the coffee belt, the plant itself, the countries that produce the most, how coffee spread around the world, how coffee is scored and sold at auction, and the coffee cultures of Italy and Japan. Practical guides explain roast levels, storing coffee, cupping, harvest seasons, altitude grades and shade-grown coffee. Newer guides cover the coffee grind size chart, French press vs pour-over, caffeine in coffee and coffee acidity, plus the two biggest threats on the farm, coffee leaf rust and the coffee berry borer.
This section also holds our origin and authenticity guides to Jamaica Blue Mountain, the coffee every page here is measured against: how JACRA certifies it, how it is graded, what the 30% blend rule allows, how to spot fakes, its history and why Japan buys most of it.

- A Short History of CoffeeFrom a Yemeni Sufi ritual to Ottoman coffeehouses, European trade and colonial plantations, coffee's documented history is stranger than its most famous legend.
- Caffeine in Coffee: How Much Is in a Cup, Shot or Decaf?How much caffeine is in a cup of coffee depends on the bean, the brew and the cup size. This guide gives the official USDA, FDA and EFSA figures, explains what changes the number, and what is known about Blue Mountain coffee.
- Can a Lab Prove Where Coffee Was Grown?Isotope ratios, trace-element fingerprints and near-infrared spectra can often tell coffee origins apart, but only against a good reference database. For most origins, paperwork is still the main proof.
- Can You Bring Coffee Back From Jamaica? Customs Rules ExplainedYes for most travellers: the US allows unlimited roasted coffee and, into the continental US, green beans, if you declare them; coffee cherries are banned and green beans may not enter Hawaii or Puerto Rico. Other countries set their own rules.
- Coffee Acidity: What It Means, pH and Low-Acid CoffeeAcidity is the word cuppers use for a coffee's brightness, and the word shoppers use when they worry about their stomach. This guide separates the two, using published studies on the acids in coffee, roast, cold brew and gastric acid.

- Coffee Roast Levels: Light, Medium and Dark Roast ComparedRoast level changes a coffee more than almost any other step after harvest. This guide explains what light, medium and dark mean, how they change the cup, and what a 2024 study found about caffeine.
- Ethiopia's Coffee Trademarks: Harrar, Sidamo and YirgacheffeFrom 2004 Ethiopia registered Harrar, Sidamo and Yirgacheffe as trademarks abroad and licensed them royalty-free, a different route to protecting famous origin names than Jamaica or Colombia took.
- French Press vs Pour-Over: Taste, Body, Health and MethodA French press steeps coffee and strains it through metal; a pour-over drips it through paper. That one difference changes body, clarity, cleanup and even how much cafestol reaches the cup. This guide compares the two step by step.
