Can You Make Filter Coffee with an Espresso Machine?
Quick answer
- Espresso machines are built for pressure, not gravity. Filter coffee relies on gravity.
- You can force hot water through grounds in an espresso machine, but it won’t be true filter coffee.
- Expect a weak, muddy, or bitter cup. Not the clean flavor you want.
- It’s like trying to make soup in a toaster. Wrong tool for the job.
- Stick to your espresso machine for espresso drinks. Get a drip brewer for filter coffee.
- If you’re desperate, a French press or AeroPress is a better alternative than an espresso machine.
If you’re looking for a better alternative to an espresso machine for filter-style coffee, a French press is a great option.
- Wash in warm, soapy water before first use and dry thoroughly
- Not for stovetop use
- Turn lid to close spout
- Easy-to-clean glass carafe
Who this is for
- The home barista who’s curious about using their espresso machine for everything.
- Anyone who only has an espresso machine and needs a coffee fix, filter-style.
- Campers or travelers who might only have an espresso machine available.
What to check first
Brewer type and filter type
This is the big one. Your espresso machine is a high-pressure beast. Filter coffee makers are gravity-fed. They use different mechanics entirely. Trying to make filter coffee in an espresso machine is like trying to use a fire hose to water a delicate flower. It’s just not designed for that gentle, consistent flow.
Water quality and temperature
Even if you could force water through, the water itself matters. Filtered water is always best. For filter coffee, you’re aiming for water around 195-205°F. Espresso machines heat water differently, often hotter, and the pressure can change how heat transfers. This difference can really mess with extraction.
Grind size and coffee freshness
This is critical for filter coffee. You need a medium grind, like coarse sand. Too fine, and it clogs. Too coarse, and it’s weak. Espresso machines need a super-fine grind to create resistance for the pressure. Using an espresso grind in a filter setup will lead to over-extraction and bitterness, or a complete clog. Freshly roasted beans are always ideal.
Coffee-to-water ratio
Filter coffee typically uses a ratio around 1:15 to 1:18 (coffee to water by weight). Espresso is much more concentrated, often 1:2 or 1:3. If you try to mimic a filter ratio with an espresso machine, you’ll end up with a huge volume of poorly extracted coffee.
Cleanliness/descale status
This applies to any coffee brewing. A dirty machine, whether espresso or drip, will make bad coffee. Scale buildup can affect water temperature and flow. If your espresso machine isn’t clean, whatever you try to make will taste off.
Step-by-step (brew workflow)
This is a hypothetical workflow. I’m not saying you should do this, but if you absolutely had to, here’s how you might attempt it. Remember, results will vary and likely won’t be great.
1. Prepare your espresso machine: Make sure it’s heated up and ready to go. Prime the pump.
- What “good” looks like: Machine is at operating temperature, ready for use.
- Common mistake: Trying to brew with a cold machine. This leads to poor temperature stability. Avoid by giving it ample time to heat up.
2. Grind your coffee: Use a medium grind, NOT your espresso grind. Think coarse sand.
- What “good” looks like: Uniform, coarse particles.
- Common mistake: Using the espresso grind. This will clog everything up. Use a separate grinder or adjust your grinder carefully.
3. Prepare the portafilter: Remove the basket. You’re not using it for its intended purpose. You might need to improvise a filter holder.
- What “good” looks like: Portafilter is clean and ready.
- Common mistake: Leaving the basket in. It’s designed for espresso pucks.
4. Improvise a filter setup: This is the tricky part. You need something to hold the grounds and let water drip through. A paper filter in a small cone that fits loosely into the portafilter might work, but it’s unstable.
- What “good” looks like: A stable setup that won’t collapse.
- Common mistake: Filter collapsing or not fitting. This will make a mess. Experiment beforehand.
5. Add coffee grounds: Place your medium-ground coffee into your improvised filter. Use a filter coffee ratio (e.g., 20g coffee for 300g water).
- What “good” looks like: Grounds are evenly distributed.
- Common mistake: Overfilling the filter. This will cause overflow.
6. Position the portafilter: Place the portafilter (with your improvised filter and grounds) into the group head, but don’t lock it in fully. You want a slight gap for water to escape slowly.
- What “good” looks like: Portafilter is seated but not locked.
- Common mistake: Locking it in too tight. This will build up too much pressure.
7. Initiate a very short pre-infusion: Run a tiny bit of water through, just to wet the grounds.
- What “good” looks like: Grounds are just saturated.
- Common mistake: Running too much water. This will push grounds through prematurely.
8. Attempt to brew: Slowly engage the pump, but very gently. You want a slow drip, not a pressurized stream. You’re trying to mimic gravity, but with a machine that wants to force.
- What “good” looks like: A slow, steady drip into your cup.
- Common mistake: Engaging the pump too hard. This will blast water through and cause channeling or overflow.
9. Monitor the flow: Watch for signs of clogging or too-fast flow. Adjust pump pressure if possible, or stop if it’s clearly not working.
- What “good” looks like: Consistent dripping.
- Common mistake: Ignoring obvious problems like spurting or no flow.
10. Stop when done: Aim for your desired yield. It might be a very small amount.
- What “good” looks like: You’ve collected your coffee.
- Common mistake: Over-extracting or under-extracting due to poor control.
11. Discard and clean: Carefully remove the portafilter and clean up the mess.
- What “good” looks like: Machine is clean and ready for its actual job.
- Common mistake: Leaving grounds and water in the machine.
Common mistakes (and what happens if you ignore them)
| Mistake | What it causes | Fix |
|---|---|---|
| Using espresso grind for filter coffee | Over-extraction, bitterness, mud, or a complete clog that won’t drip. | Use a coarser grind (medium, like coarse sand). |
| Using espresso ratio for filter coffee | Extremely weak and watery coffee, or a concentrated mess. | Use a filter coffee ratio (e.g., 1:15 to 1:18). |
| Forcing pressure instead of gravity | Channeling, uneven extraction, bitter or sour taste, potential overflow. | Use minimal pump engagement, try to mimic gravity flow. |
| Not improvising a stable filter holder | Grounds escaping, messy brew, uneven extraction, potentially no coffee. | Ensure your improvised filter setup is secure and won’t collapse under a little water. |
| Overfilling the improvised filter | Grounds overflowing the filter, leading to a muddy, undrinkable cup. | Leave space at the top of the filter for the water to bloom and drip. |
| Locking the portafilter too tightly | Excessive pressure buildup, potential damage, or no water flow. | Seat the portafilter loosely, allowing for controlled water escape. |
| Not cleaning the machine properly | Off-flavors, stale coffee taste, potential for clogs and poor performance. | Follow your espresso machine’s cleaning and descaling schedule religiously. |
| Expecting true filter coffee results | Disappointment, frustration, wasted coffee and time. | Accept that this is a workaround, not a replacement for proper filter coffee brewing equipment. |
| Using water that’s too hot or too cold | Under-extraction (sour) or over-extraction (bitter) due to temperature. | Aim for the 195-205°F range if possible, though controlling this precisely is hard here. |
| Attempting without proper tools/knowledge | Mess, wasted coffee, and a bad cup. | Know that this is a hack. A drip machine or pour-over is the right tool. |
Decision rules (simple if/then)
- If you want true filter coffee, then do not use an espresso machine because it’s designed for pressure, not gravity.
- If you only have an espresso machine and need filter coffee, then consider using an AeroPress or French press if available, because they offer more control than an espresso machine for this purpose.
- If your espresso machine’s grind is too fine, then do not attempt to make filter coffee because it will likely clog.
- If you notice grounds escaping your improvised filter, then stop the brew immediately because you’ll have a muddy, undrinkable cup.
- If the water is flowing too fast through your setup, then you are likely under-extracting and will get a weak, sour coffee.
- If the water is not flowing at all, then you are likely over-extracting or have a clog, and will get a bitter, burnt taste.
- If your goal is a clean, bright filter coffee, then an espresso machine is the wrong tool because its mechanics are fundamentally different.
- If you’re brewing filter coffee with an espresso machine, then be prepared for inconsistent results because controlling the variables is extremely difficult.
- If you have a dedicated drip coffee maker, then use that for filter coffee because it’s designed for the task.
- If you’re tasting extreme bitterness, then you’ve likely over-extracted, possibly due to too fine a grind or too much pressure.
- If your coffee tastes weak and watery, then you may have under-extracted, possibly due to too coarse a grind or not enough coffee.
FAQ
Can I just put grounds in the portafilter without a basket?
No, that’s a recipe for a huge mess. You need some sort of filter to hold the grounds and let the liquid pass through. Even then, it’s a hack.
Will it taste like espresso?
Not at all. It will likely taste like weak, muddy, or bitter coffee. It won’t have the body or crema of espresso, nor the clean flavor of good filter coffee.
What kind of coffee should I use?
Use the same beans you’d use for filter coffee. The key is the grind size and brewing method, not necessarily the bean origin, though freshness always matters.
Is this bad for my espresso machine?
Potentially. Forcing water through in an uncontrolled way could stress components. It’s definitely not what the machine was designed for.
How much coffee should I use?
Stick to a filter coffee ratio, like 1 gram of coffee for every 15-18 grams of water. For example, 20 grams of coffee for 300-360 grams (about 10-12 oz) of water.
What if I have an AeroPress?
An AeroPress is a much better option for a filter-style coffee if you don’t have a drip machine. It offers more control than trying to hack an espresso machine.
Can I use a paper filter with my espresso machine?
You can try to improvise, but standard paper filters won’t fit the portafilter properly. You’d need a very specific setup, and even then, it’s a struggle.
Is it worth the effort?
Honestly, probably not. The results are usually disappointing. It’s far easier and more rewarding to use the right tool for the job.
