Coffee & Tea Culture
The art of the perfect cup
Brewing science, origins, and culture — for everyone who loves coffee.
From bean to cup — the story of coffee
Coffee's journey spans continents and centuries. From the highlands of Ethiopia to the lush estates of South America, every origin brings its own flavour story. Understanding where your coffee comes from transforms every sip.
Brewing Science
Understand your brew
Whether you pull espresso shots, pour a V60, or love masala chai's close cousin — the fundamentals of extraction, water chemistry, and roast profiles apply everywhere.
Espresso & Extraction
Pressure, grind size, and dose — the three levers that define every espresso shot. Learn what each variable does and how to dial in your extraction.
Filter & Pour-Over
From Chemex to Hario V60, manual brewing rewards patience. Explore brew ratios, water temperature, and pouring technique for a cleaner, brighter cup.
Origins & Terroir
Ethiopia, Colombia, Coorg, Chikmagalur — every growing region imprints its climate and altitude onto the bean. Discover what makes each origin unique.
Frequently asked questions
- What is the difference between espresso and filter coffee?
- Espresso uses high pressure (9 bar) to force hot water through finely ground coffee in about 25–30 seconds, producing a concentrated, syrupy shot with crema. Filter coffee — drip, pour-over, or batch brew — uses gravity and a longer brew time (3–5 minutes) at a coarser grind, yielding a lighter, brighter cup that highlights origin flavours.
- What is South Indian filter coffee?
- South Indian filter coffee (also called degree coffee or Madras coffee) is brewed in a stainless steel double-tumbler filter by slowly dripping hot water through coarsely ground coffee mixed with chicory. The dark, strong decoction is then blended with hot milk and sugar and poured between tumblers to create a frothy, aromatic cup — a beloved ritual across Tamil Nadu, Karnataka, and Kerala.
- How does roast level affect coffee flavour?
- Light roasts retain more of the bean's origin character — floral, fruity, and acidic notes. Medium roasts develop sweetness and balance while keeping some brightness. Dark roasts emphasise body and bitterness, with roast-derived chocolatey or smoky notes that can mask origin flavours. For filter brewing, light-to-medium roasts often shine; for espresso, medium-to-dark is more traditional.
- What grind size should I use for different brew methods?
- Grind size determines how quickly water extracts from the coffee. Use extra-fine for Turkish coffee, fine for espresso, medium-fine for pour-over (V60/Chemex), medium for drip machines, medium-coarse for Aeropress, and coarse for French press or cold brew. A consistent burr grinder makes a bigger difference than the brewer itself.
- What water temperature is best for brewing coffee?
- The Specialty Coffee Association recommends 90–96 °C (195–205 °F) for most brewing methods. Boiling water (100 °C) over-extracts, producing bitterness, while water below 88 °C under-extracts, producing sourness. For espresso machines, the boiler is typically set to 93–94 °C at the group head.
