• What is biodynamic coffee farming?

  Biodynamics in coffee follows the teachings of Rudolf Steiner from the 1920s, layering intentional cosmic and biological practices onto organic farming.

• What is blockchain's impact on coffee traceability?

  Blockchain applied to coffee traceability records every step of the supply chain — from harvest to roasting through export and import — on a distributed, tamper-proof ledger accessible to all actors.

• What is climate change's impact on coffee?

  Global warming is shrinking the 'coffee belt' around the equator: several studies project that land suitable for Arabica could halve by 2050. Droughts, coffee leaf rust, unsynchronised flowering and a

• What is coffee agroforestry?

  Coffee agroforestry means growing coffee trees under a canopy of companion trees — bananas, Inga, Erythrina, hardwood species — instead of planting them in full sun. This plant mosaic regulates temper

• What is coffee leaf rust?

  Coffee leaf rust — 'roya' in Spanish — is a fungal disease caused by Hemileia vastatrix. It produces orange spots on the underside of leaves, triggers defoliation, weakens the plant and can wipe out a

• What are the decaffeination methods?

  Four main processes coexist: the Swiss Water Process (water plus activated charcoal, no chemical solvent), supercritical CO2 (gas under high pressure), natural sugarcane ethyl acetate, and the direct

• What is an espresso decoction (signature)?

  Decoction is a very ancient hot extraction technique — used for centuries in herbal teas, broths, and medicinal infusions — that competition baristas have.

• What is evolved Direct Trade in 2026?

  Evolved Direct Trade in 2026 goes beyond the simple bilateral purchase relationship between a roaster and a producer. It now integrates co-investment, radical price transparency, documented climate im

• What is experimental coffee fermentation?

  Since the early 2010s, and even more so with the rise of the 4th wave coffee movement, the most adventurous producers and roasters have been exploring.

• What is the transition to F1 hybrids and its impact?

  Traditional coffee variety selection is an extremely slow process: Arabica is a self-pollinating plant with a long cycle, and fixing genetic traits.

• What is the fine Robusta trend?

  Fine Robusta is a movement to rehabilitate Coffea canephora — the species long considered inferior to Arabica — through the selection of exceptional varieties, care in post-harvest processing, and rig

• What is fourth wave coffee?

  Fourth wave coffee extends the third wave from roughly 2015 onward by layering science, data and technology on top of it: controlled fermentations (anaerobic, co-ferments), AI-assisted roasting, senso

• What is Mountain Water Process decaf?

  The Mountain Water Process (MWP) is a water-based decaffeination method using pure spring water from Mexican glaciers (Sierra Madre Oriental (Pico de Orizaba)), without chemical solvents. Developed an

• What is nitro cold brew?

  Nitro cold brew is coffee extracted cold and then served under nitrogen pressure through a stout-style faucet. Nitrogen, which is poorly soluble in water, forms stable micro-bubbles that create a thic

• What is organic coffee and why choose it?

  Organic coffee is coffee certified under EU regulation 2018/848 on organic farming: no synthetic pesticides or fertilisers, shade and crop rotation favoured, and a segregated processing chain audited

• What is the 'precision fermentation' trend in coffee?

  What is the 'precision fermentation' trend in coffee? — What is the 'precision fermentation' trend in

• What is relationship coffee in depth?

  Relationship coffee describes a long-term, mutually beneficial supply relationship between a roaster (or buyer) and a producer or cooperative. Unlike transactional direct trade, relationship coffee is

• What is an RTD cold brew concentrate?

  Cold brew is an extraction method that uses only cold or room-temperature water, with no heat at all. The extraction duration — typically 12 to 24 hours.

• What is the signature coffee trend in bars?

  A signature coffee is a creative drink built on top of an espresso or a cold brew, combined with non-alcoholic ingredients — fruits, spices, infusions, house syrups, aerated foams — to tell an aromati

• What is a signature espresso in coffee competition?

  At the WBC and affiliated competitions (national championships, Barista League...), each competitor prepares three services: classic espresso, milk drink.

• What is supercritical CO2 decaffeination?

  Supercritical CO2 decaffeination is the most precise and aroma-preserving method currently available. It uses carbon dioxide under high pressure and temperature to place it in a 'supercritical' state

• What is Swiss Water Process decaf?

  The Swiss Water Process (SWP) is a water-based decaffeination method without chemical solvents, used primarily for organic and specialty coffees. It relies on the principle of osmotic diffusion: green

• What is third wave coffee?

  Third wave coffee is the movement that emerged in the early 2000s and treats coffee as an artisanal product of terroir, on par with wine. It favours lighter roasts, full farm-level traceability, preci

• What is decaf coffee?

  Decaf coffee is coffee from which at least 97 % of the caffeine has been removed from the green beans before roasting, according to the European standard. The process relies on a solvent — water, supe

• What is cellular or lab-grown coffee?

  Lab-grown coffee — also called cellular coffee — is produced by cultivating Coffea plant cells directly in a bioreactor, without trees, soil or farmland. Scientists extract cells from a coffee plant,

• What is yeast inoculation in coffee fermentation?

  In traditional coffee fermentation (washed, natural, honey), the microorganisms that transform the sugars in the mucilage are those naturally present in.
