Coffee Brewing Methods Explained: Pour-Over, French Press, Cold Brew and More
By Kenya Coffee School × Barista Mtaani
Coffee can be prepared in many different ways, and each brewing method can reveal different characteristics of the same coffee. For a professional barista, understanding brewing is therefore more than knowing how to operate equipment—it is about understanding water, coffee, time, grind size, temperature and extraction.
The Kenya coffee school identifies brewing methods, grinders, coffee-to-water ratio, grind setting, brewing time, water temperature, turbulence and water quality among the important areas of brewing knowledge.
1. Pour-Over Coffee
Pour-over brewing is one of the most popular manual brewing methods in specialty coffee.
Hot water is poured gradually over ground coffee held in a filter. The brewed coffee passes through the filter into a server or cup.
The method gives the barista significant control over variables such as pouring technique, flow rate, grind size and brewing time.
An SCA brewing guide, for example, provides a two-cup pour-over recipe using a medium-fine grind, a controlled bloom and a total brewing time of approximately 2:30–3 minutes.
Pour-over can be particularly useful when a barista wants to highlight clarity and distinctive flavour characteristics.
2. French Press
French press is a full-immersion brewing method. Coffee grounds are immersed in hot water before the brewed coffee is separated using a plunger and metal filter.
It is relatively simple and accessible, making it an excellent method for learning fundamental brewing principles.
A KCS French press guideline uses a medium-coarse grind and a four-minute brewing time as part of its example recipe.
Because the metal filter allows more coffee oils and fine particles into the cup than many paper-filter methods, French press can produce a fuller mouthfeel.
3. Cold Brew
Cold brew is fundamentally different from ordinary iced coffee.
Instead of brewing coffee hot and then cooling it, cold brew generally involves long, slow extraction using room-temperature or chilled water. The brewing process can take many hours.
Cold brew has become an important part of modern coffee culture and can be served in different styles, including over ice or as a base for other beverages.
Research discussed by the Specialty Coffee Academy and KCS found that cold-brewed samples could present sensory differences from hot-brewed coffee, although the coffee’s origin and roast level also influenced the final experience.
4. AeroPress
The AeroPress combines immersion and pressure-assisted brewing principles in a compact device.
It is popular among coffee enthusiasts and professionals because recipes can be adjusted significantly. Grind size, water temperature, ratio, steeping time and pressing technique can all influence the result.
This makes it an excellent tool for experimentation and learning.
5. Siphon Brewing
Siphon brewing uses controlled heat, vacuum pressure and immersion to produce coffee.
It is visually distinctive and can be an engaging method for coffee demonstrations, specialty cafés and sensory exploration.
While less common than pour-over or French press in everyday service, it demonstrates an important lesson: coffee brewing is both science and craft.
6. Espresso
Espresso uses finely ground coffee and pressurized water to produce a concentrated beverage.
It requires greater control of grinding, dosing, distribution, extraction and equipment than many basic manual brewing methods.
Espresso also becomes the foundation for beverages such as cappuccinos, lattes, flat whites and americano.
The Seven Elements of Brewing
Professional brewing education encourages baristas to think systematically.
Important variables include:
Coffee-to-water ratio • Grind size • Brewing time • Water temperature • Turbulence/agitation • Water quality • Filtration
Changing one variable can affect extraction and the sensory experience in the cup.
There Is No Single “Best” Brewing Method
A common beginner question is: “Which brewing method is the best?”
There is no universal answer.
The best method depends on the coffee, equipment, desired flavour profile, available time, brewing environment and personal preference.
A skilled barista learns to understand several methods rather than becoming dependent on only one.
Building Brewing Skills
At Kenya Coffee School, brewing forms part of broader coffee education that connects practical preparation with coffee knowledge, sensory evaluation and the wider Seed-to-Cup journey.
Barista Mtaani extends the idea of practical coffee skills into community settings, encouraging people to learn, practice and explore coffee beyond the traditional café environment.
For aspiring baristas, learning different brewing methods develops something even more valuable than the ability to make different drinks: it develops the ability to observe, measure, taste, adjust and understand coffee.
☕ Different methods. Different experiences. One remarkable journey from bean to cup. #GoPlaces
