Курс и Сертификация

Advanced espresso looks into the latest innovations in modern barista technique and recent developments in machine and grinder engineering. It also dives deep into the physics of espresso extractions and offers a big rethink on our approach to grinds distribution and the nature of channelling. You will finish this course with a clear picture of what science currently understands about espresso. In those areas where we don’t have the answers, guided by the unbelievable scientific knowhow of our Cambridge chemistry graduate and researcher Tom Hopkinson, and the generous mentorship of world expert in solubility science, Professor Steven Abbott, the BH Learn team begins to look into areas in espresso extraction that are still a mystery to science. New lessons will be added as part of our biweekly publishing schedule. See the current course curriculum below!

All of our courses and certifications are available with a BH Unlimited monthly subscription.

Advanced Espresso - Course and Certification

Processing is the second in a series of courses from Barista Hustle about coffee origin. Processing picks up where the Terroir course left off — at the precise moment that ripe coffee cherry is harvested. In this course, we learn about how coffee is looked after from the moment it ripens until it is dried and is ready to be roasted. We take an in depth look at washed, natural, and pulped natural processes, as well as looking into the most innovative new approaches to coffee fermentations around the globe. See the current course curriculum below! This is our biggest and most info packed course to-date.

Æ 1.03 Grind Size

As baristas, we’re used to discussing grind size on a regular basis, adjusting the grinder to produce finer or coarser grinds throughout the day to keep to the shot time in our recipe as the grinder heats up or cools down. However, when grinders heat up, the aperture between the burrs doesn’t seem to be changing – which means the nominal grind size hasn’t actually changed. Instead, the grind size distribution has changed. Understanding the concept of grind size distribution is key to understanding some of the more recent developments in espresso making.

Æ 1.04 Measuring Grinds

The complexity of grind size distributions that we discussed in Lesson 1.03 explains why it is so difficult to replicate the desired grind size on different equipment. Even grinders of identical models at identical settings will produce slightly different grind size distributions, thanks to small differences in alignment or wear on the burrs, for example.

For this reason, replicating recipes across two different sets of equipment (for example, in two cafes in the same chain) is not always straightforward. Using the same numerical grind setting, even on two apparently identical grinders, will not produce the same results.

It’s possible to communicate a target grind size by using a proxy measurement such as shot time, but even this has limitations. For example, a particular espresso recipe using a Mahlkoenig EK43, a recipe that tastes great on a well-aligned grinder, might suffer from underextraction flavours or even be impossible to achieve on a grinder that is less well aligned.
