11 ESPRESSO MACHINE MODS: EASY UPGRADES FOR BETTER COFFEE
You don’t need to buy the most expensive home espresso machine if you have a few tricks up your sleeve!

Want to turn a good espresso machine into a great espresso machine? A great espresso machine into something top-of-the-line? Then you’ve come to the right place!
In this post, I’ve rounded up the 11 best espresso machine mods. Some are easy swaps, others require a bit of technical know-how, but all are guaranteed upgrades. For tastier espresso, a more efficient workflow, or a fresh new look, keep reading.
The Best Espresso Machine Modifications And Upgrades
In compiling this list, I drew not only on my expertise and that of the Home Brews Coffee team, but I scoured coffee forums and surveyed a broad range of coffee professionals and serious home espresso enthusiasts. What follows are the mods that everyone agreed made the most significant impact on their espresso journey.
1. Adding a PID Controller
A PID controller controls boiler temperature and thus brew temperature. Compared to the pressure stats found on cheaper machines, a PID provides a more stable brew temperature — and a more delicious espresso (1).
Installing a PID is one of the most popular mods because it makes a huge difference in espresso quality, but it’s not the easiest. You’ll need a good understanding of the internal layout of your machine and some basic electrical skills.

2. Changing the Steam Wand
Many entry-level espresso machines include steam wands with frothing aids – like a Pannarello wand, for example. These make it easier for a novice barista to produce an airy milk foam, but in doing so, they eliminate a lot of the fine control over milk texture.
Once you’ve mastered the frothing technique, consider updating your machine with a professional-style steam wand. Your lattes will thank you!

3. Changing the Steam Tip
Even easier than changing the steam wand? Change the steam tip! This controls the speed of frothing, making it easier to steam milk.
If steaming is too quick, you can slow it down using a 1 or 2-hole steam tip. This is an especially good idea if you’re steaming small volumes of milk. On the other hand, if steaming is frustratingly slow, you might want to switch to a 3 or 4-hole tip for more power.

4. Adding an Adjustable OPV and Pressure Gauge
An overpressure valve (OPV) lets you adjust the pump pressure and thus brew pressure. Fancier models often have an adjustable OPV, but it’s an increasingly popular modification for cheaper machines. We now know that different coffees extract best at different brew pressures (2).
Of course, if you’re adding an OPV, you’ll also want to add a pressure gauge to see which brew pressure yields the tastiest espresso shot. That makes this mod one of the more complicated in terms of tools and skills required.

5. Adding Flow Control
These days, flow control (aka pressure profiling) is all the rage with serious espresso nerds. It lets you optimize extraction by varying the pressure as you pull a shot. Some high-end machines have this option built-in, like the La Marzocco GS3, Lelit Bianca, or Slayer.
There are after-market mods for those that don’t, which consist of a controllable valve and pressure gauge. ECM/Profitec makes one for E61 group heads, and the Smart Espresso Profiler from Naked Portafilter works with nearly any machine (3).
6. Upgrading the Shower Screen
The shower screen creates an even flow of water over the puck of ground coffee in the filter basket, a key to proper extraction. There are several inexpensive ways to upgrade your shower screen.
You can get a “precision” shower screen, which is carefully machined to produce a more even flow of water. Or you can further upgrade to a coated shower screen, which stays cleaner by resisting the build-up of coffee oils.
7. New Filter Baskets
Most inexpensive espresso machines come with pressurized filter baskets, which are designed to give a great-looking espresso. If you want a great-tasting espresso, it’s worth the very inexpensive upgrade to a non-pressurized basket — provided you also have access to a decent burr grinder.
Want to take it a step further? Invest in a precision basket, which is carefully machined to yield fewer clogs and better extraction.

8. Bottomless Portafilter
Okay, this isn’t exactly a mod, but it’s a popular addition to any espresso lover’s arsenal of accessories. Also known as a naked portafilter, a bottomless portafilter doesn’t have spouts at the bottom; instead, the filter basket is exposed.
Sure, this can be frustrating, but it’s also an incredible learning opportunity. If you’ve prepared your coffee puck poorly, brewed espresso will spurt all over the place. Plus, once you’ve mastered your technique, the sheer beauty of a perfect shot falling from a bottomless portafilter is unmatched.

9. Group Head Thermometer
Adding a group head thermometer is common on heat exchanger espresso machines because you don’t set the brew temperature directly in this style of machine. So adding a thermometer allows you to know your brew temperature precisely.
Because different brewing temperatures are ideal for different roast levels of coffee (for example, light roasted coffee extracts better at slightly higher temperatures), a group head thermometer is a great mod if you like to experiment with different specialty coffee beans (4).

10. Steam Wand Controls
Steam wand controls are a matter of personal preference, just like the steam wands themselves. Some people prefer joysticks for their instantaneous response, whereas others like the more tactile control of a knob.
Most manufacturers are consistent with a particular style, but many distributors will let you swap one for the other when you purchase. You can also make the change yourself at home, provided you have a bit of technical know-how.

11. Aesthetic Changes
While some people declare aesthetic adjustments a waste of money, I strongly disagree. If you’re buying an expensive espresso machine, spending a bit more to have it perfectly suit your space is well worth it for the smile it’ll bring to your face each morning.
Common aesthetic changes include swapping plastic knobs and handles for wood accents, adding stylish panels, or powder coating the machine to match your decor.

Which Espresso Upgrade Is Right For Me?
Does a list of 11 feel like an overwhelming number of possibilities? Don’t worry. It’s easy to narrow it down to just one or two that will best help you get more bang for your buck.
- Suppose you have an inexpensive appliance-grade espresso machine (like Cuisinart, Breville, Delonghi, and so on). In that case, the first thing you should do is swap the pressurized filter basket for a non-pressurized basket. It’s affordable and easy to do. Want to work a little harder? The next step would be an upgrade to a more professional steam wand. These machines also typically come with cheap plastic tampers, which you should replace with a heavier metal tamp as soon as possible.
- Entry-level prosumer espresso machines (like the Gaggia Classic Pro or Rancilio Silvia) are the most popular to mod. They’re relatively inexpensive upfront and have plenty of open space inside for adding new plumbing or wiring. If you have one of these machines, adding a PID, an OPV, and/or a pressure gauge is a great start. You could also upgrade the shower screen or switch steam tips.
- Upper-level prosumer espresso machines already have a lot of features, so in these cases, you’ll either be adding advanced functionality or adjusting the machine to suit your taste. In terms of features, a flow control device adds a whole new variable to optimize extraction. You might want to try a bottomless portafilter, change out the steam wand controls, or make aesthetic changes to suit your preferences.
- If you have a heat exchanger prosumer machine, a grouphead thermometer is an easy mod that can have a big impact.
