Fase 1 – Koffie begrijpen

Harvesting Methods and Coffee Brands – Why Not All Coffees Are Equally Easy to Brew

Some coffees remain difficult to fine-tune, because the choices made before roasting already affect your espresso.

In this video module, you'll learn why some coffee beans brew more smoothly, cleanly, and predictably than others — and how you can recognize this before you buy it.

✔ Understand why some coffees are easy to adjust and others remain structurally unstable in extraction
✔ Learn how harvesting and sorting influence crema, run-off and flavour balance
✔ Recognize why major coffee brands and specialty roasters often make completely different choices

✔ Discover what to look for on the packaging to quickly identify difficult-to-brew coffee
✔ Avoid having to keep making corrections on your machine while the real problem is already in the coffee

Why some coffee is difficult to brew

You adjust the grind, try again, and yet the espresso remains disappointing.
The flow remains fast, the crema remains thin, and the taste remains flat or bitter.

Many home baristas then look for the cause in their machine or technique.
But in many cases, the problem starts earlier — with the coffee you use.

I see this happen regularly during barista workshops.
The espresso remains difficult to adjust, no matter how often someone adjusts the grinder.
When we work with different coffee afterwards, something striking suddenly changes.

The espresso flows through more slowly.
More crema is forming.
The flavor becomes fuller and rounder.

And then the same reaction often follows:

So that's why my coffee never worked properly.

Good coffee is often surprisingly easy to brew on an espresso machine.
Not because the machine works differently, but because different choices were already made before burning.

In this module, you will discover how choices in the coffee chain—long before you open the bag—determine how predictably coffee brews on your espresso machine.

You learn to recognize why some coffee beans are much easier to use for espresso, while other coffee remains structurally difficult to fine-tune.

That insight helps you choose coffee more consciously and prevents you from continuing to look for solutions in your machine while the problem starts somewhere else.

What you learn in this module

In this video module you will learn:

why some coffee is easier to adjust on an espresso machine
why other coffee remains difficult to predict during extraction
what role coffee brands play in the choices that have already been made for you
what to look out for when buying coffee for home use

The explanation is based on insights from more than ten years of barista workshops, in which the same pattern recurs:

Good coffee is easier to brew and produces a balanced espresso faster.

Who is this module intended for?

This module is designed for home baristas who find that espresso remains difficult to get right, even when adjusting their grind.

If you work with an espresso machine such as a Sage, ECM, Rocket, Rancilio, Ascaso, La Marzocco , or another semi-automatic espresso machine, this module helps you understand why the choice of coffee beans plays a major role in the result you get in your cup.

This module belongs to the Espresso Under Control series.

This module is part of Espresso Under Control — a series of short video modules for home baristas who want to better understand how coffee, extraction, and technique are interconnected.

Each module covers one part of the espresso process, from choosing coffee beans to extraction and maintenance of your machine.

The modules are 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 espresso sometimes turn out well right away — and remain difficult with other coffee?

By following the modules step by step, you gain more insight into the choices that influence taste, extraction, and consistency.

Within the series Espresso Under Control

Within Espresso Onder Controle, this module forms the step between choosing coffee and learning to use coffee predictably on your espresso machine .

After this module on Harvesting Methods and Coffee Brands , you can continue with:

→ Module 06 – Branding: light, medium or dark roast
→ Module 07 – Burn date and freshness

Together, these modules help you understand step by step why coffee behaves a certain way on your espresso machine.

Who is this module for?

This module is intended for home baristas who:

keep turning their grinder, while the espresso hardly improves
notice that some coffee beans are much more difficult to adjust than others
wondering why one coffee produces little crema and tastes flat, while another coffee performs better straight away
want to buy coffee more consciously for their espresso machine and avoid bad purchases

Whether you're working with a Sage, ECM, Rocket, Rancilio, Ascaso, or La Marzocco , this module will help you understand why the quality of the coffee beans, even before brewing, makes a huge difference in how your espresso adjusts.

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 module, you will look differently at coffee that is difficult to brew.

You understand:

why espresso can sometimes be difficult to adjust, even when your machine is in good condition
why brand or packaging does not automatically say anything about how predictably coffee brews
why some coffees produce more crema, more body and a balanced taste much faster
How Pre-Roasting Choices Influence Your Espresso Machine Experience

This makes it easier to recognize coffee that better matches what you expect from espresso.

You will not only learn to look at coffee beans differently, but also to look differently at the moment when you think:

“So that's why my coffee never worked properly.”

What you get

Video module of approximately 7–9 minutes
Clear PDF summary with the most important insights
Direct access after purchase
Practical explanation based on more than 10 years of barista workshops by Geert-Jan de Baristaman

Recommended (try this right away):

Pick up your next bag of coffee beans and pay close attention to what's on the packaging, including origin information, brand transparency, and roasting date.

Logical next step

Roasting – light, medium, or dark roast – here you'll discover how the roast profile of coffee further determines how easy or difficult your espresso is to brew.

And like every module within Espresso Under Control, this one also ends with one goal: less guessing, more control.

Frequently Asked Questions - Harvesting Methods and Coffee Brands

Is this module suitable for beginners?

Yes. This module is specifically designed for home baristas who find that some coffees are much easier to brew than others. No prior knowledge is required. The explanation will help you quickly identify which beans are likely to work better with your espresso machine when buying coffee.

What exactly will I learn in this module?

In this module, you'll learn about the choices made before coffee even reaches the store. Think of harvesting methods, sorting, and how coffee brands source their coffee. These choices determine how predictably a coffee brews and how much control you ultimately have over your espresso machine.

How long is the video for this module?

The video module lasts approximately 7 to 9 minutes . In a short time, you'll gain a practical framework to help you better read coffee packaging and avoid bad purchases.

What do I get after purchase?

After purchase you will get immediate access to:

the full video module
a summary PDF

The video provides the explanation and context. The PDF will help you quickly find the key insights later when you're out buying coffee.

Why is one coffee easier to make than another?

Not every coffee bean is equally consistent. Differences in harvesting, sorting, and purchasing can result in coffees with greater variation in ripeness and quality. This variation is noticeable when brewing espresso. In this module, you'll learn which signals on packaging can help you choose more predictable coffee.

Does more expensive coffee automatically make better espresso?

Price can be an indicator of quality, but it's no guarantee. In this module, you'll learn how to use the information a brand provides on its packaging to choose coffee that's best suited to your machine and brewing method.

Which module should I follow next?

A logical next step is Module 3 – Countries & Flavor Profiles . There, you'll learn how origin influences flavor and how to use that information when choosing coffee beans.

If you're primarily interested in learning how to brew espresso consistently, Module 8 – The Three Golden Rules of Espresso is a strong next step.

Can I also follow these modules separately?

Yes. All modules in Espresso Onder Controle can be taken individually. This allows you to start with the topic where you expect to gain the most benefit. At the same time, the modules are interrelated, giving you a clearer overview when taking 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.

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.
