Yes. This module is ideal for beginners with an espresso machine. You'll learn why some coffee beans work better for espresso than others, and how to avoid unnecessary problems with acidic, thin, or inconsistent shots.

In this module, you'll learn how the difference between single-origin and espresso blends affects brewing ease, consistency, and flavor. You'll discover which choice is better for espresso, cappuccino, or Americano, and why the wrong bean causes unnecessary adjustment problems for many beginners.

Robusta typically grows at lower altitudes, where coffee plants are more susceptible to insects and diseases. Therefore, the plant produces more caffeine as a natural defense. As a result, Robusta contains on average about twice as much caffeine as Arabica .

This higher caffeine content contributes to the more powerful and bitter taste of Robusta.

The video is approximately 7 to 8 minutes long. In a short time, you'll gain a practical framework that will help you choose coffee more consciously for your espresso machine, reduce guesswork, and minimize the need for corrections during brewing.

After purchase you will get immediate access to:

• the video module
• a summary PDF
  

The video explains the topic step by step. The PDF will help you quickly recall the key points later when choosing coffee beans or reassessing why a particular coffee does or doesn't work well in your machine.

Not every coffee is designed with espresso in mind. Some coffees require more precision in grind adjustment, brew time, and extraction, while others are more stable and forgiving in an espresso machine. In this module, you'll learn how to better assess this difference beforehand, so you experience less frustration while brewing your coffee.

Because individual online information is often contradictory and uses general terms like flavor, roast, or origin, while in practice you want to know: which coffee works best in my espresso machine? This module translates that moment of decision into clear, practical advice for home baristas who want to reduce guesswork and build control faster.

In addition, the Espresso Under Control series is the result of 10+ years of Specialty Coffee and Barista Workshop experience from Geertjandebaristaman.

The most logical next step is Module 2 – Arabica vs. Robusta . There, you'll learn how coffee composition influences strength, bitterness, body, and balance. If you'd like to further understand why certain beans react differently in your grinder and extraction, the module on roasting or extraction is a logical next step.

Yes. All modules in Espresso Under Control can be completed individually. So you can simply start with the topic you're currently struggling with. At the same time, the modules complement each other, giving you more control as you complete multiple steps in the series.

Yes. The modules are also available as a bundle . This is useful if you want to better understand multiple aspects of espresso at once and use the series as a complete learning path.

Module 10 is temporarily available for FREE as a bonus with a review. On the Module 10 product page , you can find out exactly how to leave a review and access the bonus module.

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.

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.
