Espresso Variables - Coffee Explained (Ep. 4)

An in depth review of all the espresso variables that really matter! Learn to make great coffee, and understand how these variables interact. There is often so much confusion around which variables to adjust and when, but I hope I can help you understand the best approaches to take.

Awesome video! I'm relatively new to home espresso brewing.. What would you say is the impact of using coffee beans that have aged, or are otherwise less than ideal? I got some cheap beans to practice with before I spend more on high-quality beans. Is the extraction slower/more difficult?
Another question actually: here you explain that you do not consider pressure to be one of the variables that you can change, same as shot time. I have this problem where, to get a shot time close to the 30 second mark, my pressure ends up around 13 bar, rather than the typically recommended 9 bar. I adjust the grind such that I end up in the right ballpark for timing, but then my pressure seems way too high? Any thoughts? Or is this also just a function of using poor quality/old beans? Or is my pressure gauge lying!? 😂

Thanks for the hard work, and happy to see your channel growing steadily!

Ok, I watched quite some videos from your channel today (being stuck on the couch with lumbago) and as already mentioned, the content is simply high quality even for someone like me being non professional.
What would you advise to someone who only loves coffee with some sugar? Is the exploration of all the various facets made more difficult by sugar? I have somehow the feeling that my preference is depriving me from exploring more of this world that you're describing.
