Espresso Onder Controle

Module 6 van 10

Fase 2 – Koffie correct gebruiken

Roasting: Light, medium, or dark roast – Which roast suits your espresso and taste?

The roast of your coffee determines not only how it tastes, but also how easy your espresso is to brew.

You'll learn why different roasts behave differently in your espresso machine, and why you need to grind differently with a different roast to maintain balance in the cup.

✔ Understand what light, medium and dark roast mean for flavour, intensity and balance
✔ Learn why different roasts behave differently in your espresso machine
✔ Discover why the same grind doesn't keep working when you change coffees

✔ Quickly recognize why espresso becomes sour, sharp or bitter with a different roast
✔ From now on, choose a roast that suits your taste and how you make espresso

You buy a new bag of coffee beans.

The packaging states:

light roast
medium roast
or
dark roast .

But what does that actually mean for the espresso you are going to make?

Many home baristas choose a coffee based on a taste description or brand, without knowing exactly what the roasting of the coffee bean does to the preparation.

And you often only notice that when you make the first espresso.

One coffee is easy to extract.
The other remains sharp, thin, or difficult to balance.

Many people then try to solve that with grinding or dosing.

While one factor often already determines how a coffee is brewed:

the roasting of the coffee bean.

In this module, we therefore look at the following important decision point regarding coffee:

light, medium, and dark roast.

Branding and espresso

Roasting determines how a coffee bean behaves when hot water flows through it.

Therefore, the chosen roast influences:

how to extract an espresso in your machine
how intense or rounded the flavor becomes
how a coffee reacts to adjustments in your grinder
and how well a coffee works for espresso or other brewing methods .

When you understand what roasting does to a coffee bean, it becomes much easier to choose a roast that suits the taste and brewing method you are looking for .

This module is part of the Espresso Under Control series — compact video modules for home baristas who want to better understand their espresso step by step.

Together, the modules form a logical system in which you learn how coffee beans, roasting, extraction, and technique are interconnected.

The explanation in this module is based on insights from more than ten years of barista workshops by Geert-Jan de Baristaman , in which the same question keeps coming back:

Why does one coffee react so differently in my espresso machine than another?

What you learn in this module

In this video module, you will discover how branding influences the way coffee extracts .

You will learn, among other things:

what the terms light, medium, and dark roast mean
how branding can influence taste, intensity, and balance
why different roasts behave differently in an espresso machine
why the same settings don't always work when you switch coffees
how to consciously choose a roast that suits your taste and brewing method.

When you understand this, it becomes easier to choose coffee and to better understand why your espresso sometimes reacts differently than expected.

Do you want to discover afterwards how freshness and roast date influence taste and extraction?

Then view Module 07 – Burn date and freshness .

Do you want to understand exactly how under- and over-extraction occur and how to correct it ?

Who is this module for?

This module is intended for home baristas who notice that their espresso suddenly reacts differently when they switch coffees.

You adjust your espresso and everything seems to be working fine.

But the moment you open a new bag of coffee, something changes:

the espresso runs faster or slower
the taste becomes sharper or more bitter
the same settings suddenly no longer work.

Many home baristas then look for the cause in their machine or grinder.

Yet that difference often starts even earlier — with the roasting of the coffee bean .

Whether you work with a Sage, ECM, Rocket, Rancilio, Ascaso or La Marzocco , this module will help you understand why different roasts behave differently in an espresso machine.

This module is part of Espresso Under Control — a series of video modules that teaches you step-by-step how coffee beans, roasting, and extraction are all related.

What will change after this module?

After this module you will understand why the same settings do not always work when you change coffee.

You learn to recognize:

why light roasts often react differently than dark roasts
why some coffees need to be ground finer than others
why espresso sometimes becomes sour or bitter when the roast and grind are not matched
how roasting affects solubility, extraction, and balance.

This makes it easier to understand why your grinder sometimes needs to be reset when working with different coffee.

Many home baristas discover after this module that their machine often works well — but that the roast of the coffee determines how you should adjust it.

Frequently Asked Questions - Roasting: light, medium, or dark roast

Is this module suitable for beginners?

Yes. This module is especially suited for beginners who find that coffee sometimes tastes too sour or too bitter without fully understanding why. You'll learn how roasting influences flavor, intensity, and extraction, so you can make more informed choices when buying coffee beans.

What exactly will I learn in this module?

In this module, you'll learn how different roast levels—light, medium, and dark—affect flavor perception, solubility, and how to adjust your espresso machine. You'll discover how to choose a roast that best suits your taste preferences and brewing style.

How long is the video for this module?

The video module lasts approximately 8 minutes . In a short time, you'll gain a clear framework that will help you better recognize branding and understand how that choice affects grinding and extraction.

What do I get after purchase?

After purchase you will get immediate access to:

the video module
a summary PDF

The video explains the relationship between roasting, flavor, and extraction. The PDF helps you quickly recall the key insights later when using different coffee beans.

Why does one coffee taste sour and another bitter?

The flavor of coffee is influenced, among other things, by the roast. Shorter and longer roasts develop different flavor structures in the bean. In this module, you'll learn how roast relates to flavor balance and why that affects how your espresso tastes.

Why do you sometimes need to adjust your grind when you change coffee?

Not every coffee bean has the same structure. Due to differences in roasting, a bean can be harder or softer, and reacts differently during grinding and extraction. In this module, you'll learn why this happens and how to recognize it when using new coffee beans.

Which module should I follow next?

If you want to understand how to recognize and correct flavor issues like sour or bitter espresso, Module 8 – The Three Golden Rules of Espresso is the logical next step. There, you'll learn how extraction works and how to restore balance to your cup.

Can I also follow these modules separately?

Yes. All modules in Espresso Under Control can be completed individually. This allows you to start with the topic where you expect to gain the most benefit. At the same time, the modules build on each other, giving you more control as you complete multiple steps in the series.

Is this an online barista course?

Espresso Onder Controle isn't a general hospitality training program or a certification program. It's a practical, digital training for home baristas who want to brew better espresso on their own semi-automatic espresso machine.

The modules consist of focused video lessons and summary PDFs that you can follow independently. You choose the topics that best address your needs: bean selection, roasting, extraction, maintenance, or beverage composition. You don't have to complete a full course, but you can work with it like a toolbox.

The content is based on practical experience from home workshops and corporate training sessions, and is applicable to virtually any home piston machine — from Sage and Ascaso to ECM, Rocket or La Marzocco Mini.

If you work with a fully automatic coffee machine such as Jura or a fully automatic De'Longhi, some principles are useful, but the system is primarily developed for machines where you have control over grinding, dosage and extraction time.

The goal isn't a diploma. The goal is control over your espresso.

Choose the modules that best suit your needs or work step by step to gain more control over flavor, extraction, and bean selection. All modules can be completed individually and are directly applicable to your own espresso machine.

Can I also learn this during a barista workshop?

Yes.

In addition to these online modules, I also offer private barista workshops at home on your espresso machine , where we look at your espresso machine, coffee grinder, and coffee beans together.

During such a workshop, you will learn step by step how to fine-tune your espresso and which choices influence taste and extraction.

Many home baristas use the modules as a foundation of knowledge and then opt for a workshop to personally optimize their setup.
