The 3 Golden Rules of Espresso – Why Your Shots Keep Changing (and How to Stop It)

Yes. This module is especially helpful for beginners, because you'll learn how espresso becomes logical once you're working with a set system. Instead of guessing or constantly trying something different, you'll learn the three measurable factors that determine whether a shot is balanced.

In this module, you'll learn how to make espresso controllable using three fixed rules. You'll discover how these three factors interact, what to maintain, what to adjust, and how to gradually brew more consistent espresso on virtually any espresso machine.

The video module lasts about 10 minutes . You'll learn a practical, down-to-earth system that you can immediately apply when making espresso.

After purchase you will get immediate access to:

• the video module
• a summary PDF
  

The video explains the system step by step. The PDF helps you quickly return to the basics during practice, so you don't have to guess again when a shot doesn't go as expected.

This is often because there's no established system used during the setting process. If the three rules in this module aren't applied, variation arises without you knowing exactly where it comes from. In this module, you'll learn how to reduce these variations to a controllable process.

Because a lot of free information offers isolated tips, while you need a clear system for espresso. This module boils down the basics to three measurable rules that together ensure control, repetition, and better extraction. This makes it practically useful, even if you've already watched a lot of individual videos or blogs.

All modules in the Espresso Under Control series also emerged from 10+ Specialty Coffee and barista workshop experience from Geertjandebaristaman .

If you want to better understand why different coffee beans react differently to grinding and extraction, Module 6 – Light / Medium / Dark roast is a good fit.

If you want to be sure you're working with fresh coffee that can still perform well, Module 7 – Roast Date and Freshness is also a logical addition.

Yes. All modules in Espresso Under Control can be completed individually. This is also one of the most crucial modules in the series, as it brings together a lot of previous knowledge and practical application at the machine.

A digital coffee scale and a shot glass make this module much more practical. This allows you to better monitor the system inside the module while brewing espresso.

Yes. The modules are also available as a bundle . This is useful if you not only want to learn how to brew espresso reliably, but also want to better understand which beans, roast, and freshness are best suited to that.

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.

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.
