About Cupheine
Last updated
Cupheine is an independent library of coffee knowledge — everything from how a coffee cherry becomes the beans in your grinder to how to pull a balanced shot of espresso at home.
Coffee is one of the most widely enjoyed drinks on earth, and one of the most misunderstood. Myths travel fast ("dark roast has more caffeine"), and good information is scattered across forums, packaging and research papers. Cupheine brings it together in one place, explained clearly.
What you'll find here
- Brewing guides with precise, repeatable recipes — weights, temperatures and times, not vague scoops
- Explainers on species, varieties, origins, processing and roasting
- Espresso fundamentals, from dialing in to milk texturing
- Health and science — caffeine, extraction and what the research actually says
- Recipes for classic café drinks you can make in your own kitchen
- A coffee glossary with plain-English definitions of the words you meet on coffee bags and café menus
How we write
- Answer first. Every article opens with the key takeaways, then explains the why.
- Accurate and sourced. We check facts against primary sources — scientific research, standards bodies such as the Specialty Coffee Association, and food-safety authorities.
- Practical. If you can't follow it in your own kitchen, it isn't finished.
- Kept up to date. Coffee knowledge evolves. Every article shows when it was last updated, and we revise guides as standards and research change.
