You have a capsule coffee machine and are thinking about switching to a portafilter. What changes? Is it really that complicated? And does the coffee taste better afterward?
In short: A lot changes. It's not complicated. But there's a learning curve ahead. And the espresso? That'll knock your socks off.
We'll show you what you need to know before buying, which accessories are really necessary, and how to nail your first espresso shot.
Capsule vs. Portafilter: What's the Real Difference?
A capsule machine is designed for maximum convenience: insert capsule, press button, done. Pre-dosed coffee grounds, fixed water amount, no mess, minimal effort. The result is a functioning espresso, but not a particularly good one.
The main reason is the brew ratio. A typical capsule machine brews with around 5 grams of coffee and fills the cup with 50 to 70 grams of water. That's a ratio of about 1:10. The espresso becomes thin, lacks body, and has no texture.
With a portafilter, we brew with 16 to 18 grams of coffee and extract about 45 grams into the cup for a double espresso. Ratio: 1:2.5. For a single espresso, the ratio is the same. It's a fundamentally different drink. Stronger, fuller, silky. None of that comes out of a capsule.
| System | Coffee Amount | Output | Ratio | Character |
|---|---|---|---|---|
| Capsule machine | ~5 g | 50–70 g | ~1:10 | thin, watery, little texture |
| Portafilter | 16–18 g | ~45 g | ~1:2.5 | strong, full-bodied, silky |
At your first sip from your own portafilter, you might be startled. This espresso is strong. Exactly as it should be. But also exactly how you'd get it at the first Italian gas station on the way south.

The Grinder Comes First, Not the Machine
This is the most important sentence for everyone starting out: The grinder is more important than the espresso machine.
An espresso machine is basically hot water under pressure. What controls the espresso is the grind size. Ground too coarse, the water runs through too quickly and the espresso becomes watery and under-extracted. Ground too fine, too much resistance builds up and the shot takes forever or stops completely. The grinder is your most powerful control.
As a rule of thumb, we recommend splitting your budget in half. 50 percent for the portafilter machine, 50 percent for the grinder. If you invest 600 euros, buy a machine for 300 and a grinder for 300 euros, not a 500-euro machine with a cheap grinder added.
For beginners, there are now very good grinders under 300 euros. The G-Iota DF54 is a well-known example with excellent value for money. If you want to approach grinder selection systematically, you'll find an overview by grinder type and budget in our grinder articles.
Manual grinders also work very well with a portafilter if they grind fine enough. For daily use, electric grinders are more convenient. But if you grind manually in the morning, you'll have a more relaxed routine. We have several manual grinders in stock and provide recommended grind sizes for espresso.
Portafilter machines with built-in grinders sound convenient. We advise against them: the integrated grinders are almost always the weakest part of such combo machines. More on that here.
The Accessories You Really Need
Besides the machine and grinder, you'll need a few more things. The list is manageable.
Scale (Essential). This is absolutely crucial. You need to know how much coffee you're using and how much espresso lands in the cup. Without a scale, you can't work reproducibly or adjust the grind size meaningfully. A simple kitchen scale works to start. Our espresso scale with timer.
Tamper. For even compression of the coffee grounds in the portafilter. Often included with the portafilter. But a good tamper with the right diameter makes the work noticeably easier. Tampers in our shop.
Knock box. The container where you knock out the spent coffee puck. You can also knock it straight into the trash, but the basket likes to fall out and that's annoying. Our knock box.
Barista towels. You need at least two separate towels: one for the portafilter, one for the steam wand. Never use the same one for both. Barista towels in a 3-pack.
Milk pitcher. If you want to steam milk, you'll need a pitcher. We've developed our own stainless steel versions that are a joy to use for beginners and advanced users alike. Milk pitchers in our shop.
Plan for roughly twice as much space as your capsule machine takes up. Machine, grinder, knock box, scale—it all needs room. If you have a narrow kitchen, you should measure before buying.
Making Espresso: Step by Step
The routine at the portafilter becomes second nature after a few tries. Here are the parameters, assuming a double basket that holds 16 to 18 grams of coffee. For smaller baskets, keep the brew ratio and scale down.
The grind size is your most important control. If the shot runs through in under 20 seconds, the coffee is ground too coarse: grind finer. If it runs too slowly or not at all, it's too fine: grind coarser. This is how you dial in the right setting.
"Put a small notepad and pencil next to your espresso machine and jot down: how much coffee, grind setting, output grams, brew time, and how it tasted. After a few tries, you'll have your recipe and can always come back to it."

The Three Most Common Beginner Mistakes
These mistakes happen to almost everyone. It helps to know them in advance.
1. The double-walled basket. Many entry-level portafilter machines, including the De'Longhi Dedica, come with a double-walled basket. This basket has only a single hole on the underside instead of many small holes. It creates artificial backpressure and thus crema, regardless of how fresh or coarse the coffee is.
The problem: You don't get honest feedback on your grind size. The result always looks the same no matter what you do. Switch to a single-walled basket as soon as possible. Double-walled vs. single-walled basket
2. Stale coffee. Fresh coffee releases CO₂ during brewing and builds resistance. Stale coffee doesn't. Only buy coffee that's at most two months old from the roast date. Good roasters put the roast date on the bag.
3. Machine not properly preheated. A machine like the Dedica shows brew readiness after a few minutes, but the portafilter is still cold at that point. Solution: Run a blank shot of hot water through the inserted portafilter, then pull your espresso.

Which Coffee Is Right for Capsule Switchers?
If you're coming from a capsule machine, you're probably used to dark, strong flavor notes: chocolatey, somewhat bitter, heavy body. That's a good starting point.
Start with espressos that are dark roasted and forgiving. Even if you make a mistake at the beginning, it still tastes good. Lighter roasted coffees are complex and rewarding, but they forgive little when it comes to grind size and brew temperature.
For us, the Compadre is a good entry point: strong, chocolatey, classic Italian, and very forgiving to prepare. If you want a slightly more complex start, the Apas is a good choice. If you want to try different styles first, the Espresso Sample Set is a great start.
Over time, you'll get to know your taste and can work your way further into the world of specialty coffees. But there's no rush.
Summary
Switching from a capsule machine to a portafilter is a real commitment: more space, more accessories, a small learning curve. But the curve is short. And what's waiting on the other side is an espresso that's nothing like what comes out of a capsule.
The key takeaways: Buy a good grinder first, not the most expensive machine. Invest in a scale. Get fresh coffee. Write down your first recipe.
