Start with Espresso Under Control – free introduction for better espresso at home

Many coffee lovers buy an espresso machine and expect good coffee to follow automatically.
In practice, it often turns out to work differently.

Not because the machine is bad, but because a few important choices are almost never explained.

That is why I often say in my workshops: to measure is to know.
Not because coffee needs to be complicated, but because you only gain control when you understand what you are doing — and can repeat the same steps.

Good espresso, therefore, is not created by hoping it goes well, but by understanding what you are doing.

What makes Espresso Onder Controle different

The Espresso Onder Controle series is designed to help home baristas build that insight step by step. Everything you learn in the modules stems from 10+ Specialty Coffee and barista workshop experience from Geertjandebaristaman .

You won't get any loose tricks.
No long stories.
No complicated theory.

Only the steps that actually affect your coffee in practice.

In each module, we cover one topic that directly influences taste, control, and consistency . Together, these modules form a logical system that helps you learn to understand what happens before, during, and after brewing espresso.

How the series is structured

The choices that influence your coffee begin the moment you buy coffee beans.

After that, other factors also play a role, such as:

origin and flavor profiles of coffee
roasting and freshness of coffee beans
espresso extraction and grinding
maintenance of your espresso machine
and correctly preparing coffee drinks

By understanding those steps and applying them consistently, you change making espresso from hoping it goes well to understanding what you are doing .

About Geert-Jan the Barista Man

My name is Geert-Jan, also known as Geertjandebaristaman .

Over the past ten years, I have helped hundreds of home baristas brew better espresso during workshops and training sessions. I see the same thing recurring time and again: making good coffee doesn't have to be complicated, but you do need to know a few fundamental choices.

These modules are designed to explain those choices clearly and practically, so that you can immediately apply them at home to your own espresso machine.

How to use these modules

You can use the modules in two ways.

You can follow them consecutively as a complete series, so that you understand step by step how bean selection, extraction, and technique are interconnected.

Or you use them as a reference when you notice you are getting stuck somewhere. For example, when your espresso suddenly tastes different, flows faster, or has less body.

Each module ends with one concrete insight or action that you can immediately put into practice.

Part of Espresso Under Control

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

In this series, you will learn how different factors come together in the cup:

- which coffee beans you choose
- how branding and freshness have an influence
- how espresso extraction works
- and how to keep your machine stable

Each module covers one part of the espresso process. Together, they form a logical system that allows you to gain more control over taste, extraction, and consistency, step by step.

The explanation in this series 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:

How do I get better espresso at home without continuing to guess?

The first step

The first step starts with the coffee beans you buy.

That is why the series starts with Module 02 – Arabica vs Robusta . In that module, you will discover how two different types of coffee beans can result in a completely different flavor profile — and why that choice already influences what you ultimately taste in your cup.

Start slowly.
Work step by step.

And gain increasing control over your coffee choices — and with them, your coffee preparation.

Who is this module for?

This module is designed for home baristas who:

bought an espresso machine and noticed that good coffee at home doesn't come naturally
want to learn how to make better espresso, but don't really know where to start
want to get an overview of bean selection, extraction and machine use
need a logical starting point instead of isolated tips and tricks

Whether you work with a Sage, ECM, Rocket, Rancilio, Ascaso, La Marzocco or another semi-automatic espresso machine, this introduction will help you understand how the Espresso Under Control series is built and how to best use it.

This module is part of Espresso Onder Controle —a modular training program for home baristas who want to better understand their espresso step-by-step and brew it more consistently. Each module covers one crucial part of the process, so you can learn specifically where your greatest gains lie.

What will change after this module?

After watching this introduction, you'll look at good espresso at home differently.

You understand:

that good coffee does not come out of an espresso machine by itself
that control starts with choices that you learn to understand and repeat
that the series is constructed as a logical system, not as individual coffee tips
which topics will help you step by step to make better espresso at home

This makes it easier to get started in a targeted manner, without getting lost in scattered advice, YouTube videos or conflicting information.

After this module you will also know what your first real step is:

the coffee beans you buy.

That's why the series starts with Module 02 – Arabica vs Robusta , in which you discover how two different types of coffee beans can give a completely different taste character.

What you get

Free video module of approximately 2–3 minutes

Recommended (try this right away):

Next time you have a cup of coffee, pause for a moment and ask yourself:

Do I know why this coffee tastes like this, or do I hope it turns out well?

Logical next step:

Arabica vs. Robusta – here's what two different types of coffee beans mean for the taste, strength, and anticipation in your cup.

And like every module within Espresso Under Control, this introduction also revolves around one goal: less guessing, more control.

Frequently Asked Questions

Who is this free introductory module intended for?

This free introductory module is designed for anyone who wants to make better coffee with an espresso machine, but finds that good results still depend too much on chance. Whether you're just starting out or have been making coffee for a while without really understanding why the flavor varies, this module will help you understand the basics of the series and get off to a good start.

What exactly will I learn in this introductory module?

In this module, you won't learn directly how to adjust your espresso, but you will learn how the series is structured and why control begins with the choices you make before and during brewing. You'll discover how to use the modules, what to expect from them, and why good coffee isn't about luck, but about repeatable steps.

Is this module also useful if I have been making espresso for a while?

Yes. This module is especially valuable if you've been making espresso for a while but find your results remain inconsistent. You'll quickly gain insight into what this series focuses on: not on individual tricks, but on consistent choices that influence flavor, consistency, and control.

Will I only get a video or also a summary?

After accessing this module, you'll receive a short video and a summary PDF. The video provides the context and explanation. The PDF is intended as a concise memory aid, allowing you to quickly recall the key points later.

Do I need to take this module before viewing the other modules?

That's the smartest route. This introduction explains how the series works and helps you understand why the topic order makes sense. This way, you'll get more out of the paid modules. At the same time, you can also take the other modules separately if you already know where you're struggling.

What's the best next step after this free introduction?

The next logical step is Module 2 – Arabica vs. Robusta . This is where the first real coffee choice begins: which type of coffee bean suits your taste preference, strength preference, and coffee drinking style? This is often the first factor that influences your final espresso.

Do I need any additional tools to start this series?

You don't need any additional tools for this introductory module. If you want to gain more practical control over your coffee afterward, a digital coffee scale is one of the first useful tools. It replaces guesswork with fixed amounts, making your results more consistent right away.

Is this module really free?

Yes, this introductory module is free. It's your first introduction to the Espresso Under Control series, allowing you to discover, risk-free, whether this learning method is right for you.

Can I also buy the modules separately?

Yes. All modules can be taken individually or purchased individually. At the same time, they are interrelated, providing more context and coherence if you take multiple modules 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.
