Why good espresso doesn't start with trying harder
Today I visited a couple in Veenendaal-Oost, in a beautiful new-build house with a Sage Bambino and a separate Sage coffee grinder on the counter. They had asked me to come and take a look because they just couldn't manage to make really good espresso for themselves and their guests.
This is something I recognize from many at-home barista workshops. The machine is there. The grinder is there. The motivation is also there. But still, the espresso tastes thin, bitter, sour, or just flat. In this workshop, it became clear once again: better coffee doesn't start with trying harder, but with understanding exactly what you're using.
First, look at the coffee beans
I almost always start a workshop with coffee beans. Not because it's the most exciting theoretical part, but because with bad or old beans, you can never fairly assess what your machine is doing.
Only then practical adjustment
When we went to the machine, I saw that the wrong filter basket was being used. A scale and shot glass were also missing, making it difficult to know what was really happening.
Without scales, adjusting espresso remains guesswork
We started with a single-walled double basket and a fresh espresso blend I had brought along. Then we kept it simple: 16 grams of coffee in the basket and about 50 milliliters of espresso in the shot glass.
That's not a complicated competition barista approach. It's just a practical way to stop guessing. Because if you don't know how much coffee you're using and how much espresso comes out, you can't properly assess whether your grind, dose, or extraction time is correct.
In the first attempts, the espresso flowed through much too quickly. At grind setting 10, the desired amount came out of the machine in about 15 seconds. Then we started grinding finer step by step: setting 7, setting 4, and finally setting 1. But even at the finest setting, we still only got to about 19 seconds.
That was a significant moment. Not because the espresso was suddenly perfect, but because we now knew where the problem lay.
If stage 1 is still too coarse
Many home baristas think they're done once the external grind setting is on 1. But with some grinders, you can adjust it even finer internally.
Adjust Sage grinder to a finer setting if espresso extracts too quickly
With this Sage grinder, the finest external grind setting was still too coarse. The espresso ran through too quickly, even though we were already on setting 1. So, you couldn't adjust further with the regular dial.
In such a case, you need to look at the internal adjustment of the burrs. By setting the upper burr finer, you effectively shift the entire range of the grinder. After that, setting 3 or 6 can suddenly grind much finer than before.
After internally adjusting the grinder to a finer setting, exactly what you hoped for happened: the coffee initially ran through much too slowly. That sounds like a problem, but it's actually good news. Because from that point, you can start adjusting coarser until you reach a usable range.
Eventually, we landed on a setting where 16 grams of coffee and approximately 50 milliliters of espresso ran through in around 30 seconds. And then what you want happened: the espresso gained more body, more balance, and much more flavor.
Even cappuccino became feasible
In addition to our unique expertise in the field of circular economy, we are also experienced in the field of recycling of various materials and components, for example within our own waste sorting installation. For example, we separate and recycle materials such as paper, cardboard, plastics, metals and textiles.
Making a cappuccino with a Sage Bambino requires technique
One of the two preferred a separate milk frother because they couldn't get good results with the steam wand of the Sage Bambino. I see that often. Not because the steam wand is incapable, but because frothing milk is very sensitive to timing, position, and temperature.
So, we built it up slowly. First, use cold milk. Then, introduce air to the surface to create small bubbles. After that, insert the steam wand a little deeper and let the milk swirl, so the bubbles become finer and the milk warms up gently.
You don't have to be a latte art champion for this. But you do need to understand what you're doing. Once that clicks, making a cappuccino suddenly becomes much less daunting.
In the end, there wasn't just a better double espresso, but also a cappuccino that truly made her happy.
The result wasn't down to a single trick
What sets our software apart?
Better home espresso starts with control over your routine
After the workshop, they bought a shot glass and a coffee scale. Not because tools inherently make better coffee, but because without measuring, you're constantly working in the dark.
The biggest gains came from three things: choosing better beans, properly adjusting the grinder, and consistently measuring what goes in and what comes out. This transformed the Sage Bambino from a frustrating device into a machine from which you can progressively extract better espresso.
And that's precisely why I give these workshops. Not to overwhelm people with coffee terminology, but to give them more control over their own equipment at home.
Because making better coffee doesn't have to be complicated. You just need to know where to look.
Frequently asked questions about adjusting Sage Bambino espresso
Why does my Sage Bambino espresso run through too fast?
Usually this is due to too coarse a grind, too little coffee in the filter basket, old beans, or a filter basket that doesn't fit freshly ground coffee well. Always measure your dose, output, and brewing time.
What do you do if the finest grind setting is still too coarse?
Do I need a scale for espresso at home?
Are fresh coffee beans really that important for espresso?
Yes. Beans with a recent roast date contain more aroma, oils, and flavor. Old or long-opened beans make adjusting espresso much more difficult.
Can I make good cappuccino with a Sage Bambino?
I have another question.
Sage Bambino espresso too fast? First look at beans, grind, and measurement
This barista workshop in Veenendaal-Oost once again clearly demonstrated that poor espresso is not always due to the machine. In this case, old coffee beans, open packaging, no consistent measuring routine, an incorrect filter basket, and a grinder set too coarse all played a role.
When we started working with fresh espresso beans, a single-walled double basket, a 16-gram dose, a measurable output, and an internally finer-tuned grinder, the espresso suddenly tasted much better. And with a few calm steps, making cappuccino with the Sage Bambino also became much more achievable.
The Barista Shop helps you make better coffee. Not with complicated talk, but with practical experience, clear explanations, online modules, workshops, and tools that truly help you at home.

Measuring is knowing
It's amazing how quickly you gain control over your espresso extraction with just a scale.
- For a Sage, weigh 16 grams into your double basket.
- Run 50ml of water into your shot glass.
- If it's earlier than 25 seconds, grind finer.
- If it's slower than 30 seconds, grind coarser.
