ROCKET PORTA VIA REVIEW: FIRST PORTABLE PROSUMER MACHINE

Does anyone really need a portable prosumer espresso machine? I tested the Rocket Porta Via to find out.

Are you so keen on your espresso machine that you can’t imagine a vacation without it? You’re not alone. The team at Rocket Espresso knows precisely how you feel, and that’s why they designed the Porta Via.

It’s billed as the world’s first truly portable prosumer espresso machine, which struck me as an interesting but potentially impractical concept. Does this machine have a valid use case, or is it just a gimmick?

I reviewed it myself and spoke with local on-the-move coffee businesses to learn more. Read on for answers.

A Full Review of the Rocket Porta Via

The Rocket Porta Via is designed for the espresso lover on the go. Indeed, the name is Italian for “take away.” But this isn’t the sort of portable espresso machine you toss in your backpack for the weekend; it’s a full-blown prosumer espresso machine in a box (1).

Keep reading for all the details about this unique brewer and find out if it’s the travel companion you’ve been waiting for. Spoiler alert: it’s likely not.

Key Brewing Features And What They Mean

First and foremost, the Porta Via makes exceptional espresso. It’s not just good for a portable espresso machine; it makes good espresso — period.

At its heart is an innovative 40-ounce heat exchange boiler with two separate chambers, a 0.5 L brew boiler and a 0.8 L steam boiler. This setup lets you brew and steam simultaneously while maintaining a tiny footprint.

An integrated PID controls the boiler temperature, which provides improved temperature stability and accuracy compared to a pressure stat. However, be aware that it isn’t user-adjustable. You’ll need to use cooling flushes if you want to tweak the brew temperature.

You’ll find the traditional 58mm diameter E61 group head on the front of the machine and a high-end Ulka vibration pump inside (2). These are components commonly found in prosumer machines but never (until now!) seen in portable options.

The front of the Porta Via has a professional quality pressure gauge to monitor the boiler pressure. Honestly, I prefer a pressure gauge that reports brew pressure – a more useful metric, in my experience. But any pressure feedback is better than none.

What It’s Like To Pull Shots With The Porta Via

User-friendliness is where this machine kind of falls flat for me. What it gains in portability, it loses in practicality, as it needs to be assembled before use. That really limits the number of people who will find value here. 

Assembly is undeniably quick and easy, especially once you’ve done it a time or two. With its compact size and 1050 Watt heating element, you can set it up and be ready to brew in as little as 15 minutes. 

The water reservoir is unusual. While most espresso makers have a plastic tank hidden at the back of the machine, the Porta Via has a stainless steel reservoir protruding from the top like a chimney. This is smart because it allows for a relatively large capacity (2.9 liters) without forcing a more significant footprint.

With the machine assembled and heated, and the water tank full, pulling a shot is identical to any other semi-automatic E61 machine. Prepare the portafilter, slot it into the group, and use the lever on the size of the group to start and stop the shot. There is no automation here – no presets, no digital display.

I was impressed by the number of accessories included, all of which slot cleverly into the carrying case. While most manufacturers might toss in a cheap plastic tamper, the Porta Via comes with a hefty metal tamper, a set of porcelain cups and saucers, and a 12-ounce frothing pitcher.

Cleaning and Maintenance

The day-to-day cleaning and maintenance involved with the Rocket Porta Via are the same as for any prosumer-grade espresso machine. Backflush as the manufacturer recommends, use filtered water, and generally keep the exterior tidy and free of coffee residue.

The only challenges arise if something goes wrong. While the E61 group head is widespread and accessible to service, the internals of this machine are unique. Because it’s designed to be compact, things are pretty cramped, making service more of a challenge, especially if you hope to DIY. Likewise, the unusual boiler design will be foreign to many technicians, so you’ll probably want to deal with the manufacturer or distributor directly if something goes wrong.

Steam Power Takes A Back Seat

Steam power isn’t a high priority for this espresso machine, but the milk frothing system is perfectly adequate.

In my testing, the steam pressure hovered around a modest 1.2 bars, and it took me less than 30 seconds to steam 6 ounces of milk for a latte. That’s nothing to complain about, especially from a portable machine.

Unfortunately, there is no dedicated hot water wand nor means of getting hot water from the steam wand, so Americano lovers will have to travel with a kettle as well (3).

No Compromises To The Legendary Rocket Quality

Rocket espresso machines are well known for their build quality and stylish branding, with the iconic R logo and rocket-styled feet. This is no accident, according to founder Andrew Meo. Rocket is a relatively new brand, and he wanted to go above and beyond to stand out from its more established competitors.

That commitment to quality is apparent in the Porta Via espresso machine, which features stainless steel throughout, including the casing, drip tray, and even the water reservoir. The chrome-plated brass bottomless portafilter is commercial grade, and the hard shell carrying case is incredibly durable when packed away, with heavy-duty clasps locking it in place.

Size, Weight, And Portability

Let’s talk about what portability really means in this context. The Porta Via packed into its case measures 17.5″ deep by 21.7″ tall by 9.2″ wide and weighs 65 pounds. As a fairly small lady, I would describe it as “packable” rather than “portable.” I need a dolly to get it from my home to my car and assistance to lift it into the trunk. 

On top of that, it needs to be paired with a decent espresso grinder. The baskets aren’t pressurized, which is absolutely a good thing, but it means that pre-ground coffee simply won’t produce great shots.

Do The Ends Justify The Costs?

I have a hard time recommending the Porta Via. I simply can’t wrap my head around who this machine is really for. 

It retails at just under $3000 before taxes. At that budget, you can easily find other, more practical and feature-heavy heat-exchanger or dual-boiler prosumer espresso machines for home use. They just won’t be packable.

Conversely, there are more practical options for most forms of travel if you’re willing to forgo the prosumer quality. Pretty much any espresso machine is packable if you save the box and styrofoam it came in. I’d be more inclined to pack my little Breville Bambino for a road trip than to fill my trunk with 65 pounds of espresso maker.

I know what you’re thinking: what about espresso carts or catering companies? Those are use cases for a premium portable machine. True! But everyone I spoke to in this industry already had a decent single-group prosumer espresso machine and a system for carting it around. It’s a problem that can be (and has been) solved without designing a whole new espresso machine like the Porta Via.

Don’t Buy the Rocket Porta Via If…

• You don’t care about portability: If you don’t need a portable espresso machine that can hit the road with you, the novelty of Porta Via’s design will wear off pretty fast. Instead, look at the Rocket Espresso Appartamento, another compact heat exchanger machine designed for home use. Or upgrade further to something like the Rocket Mozzafiato, Rocket Giotto, or Rocket Espresso R58.

• You care a lot about portability: On the other hand, if you want a portable espresso machine that you can toss in a backpack or carry around in your pocket, the Porta Via is not the one. Consider something like the Flair or the even tinier Wacaco Picopresso. Both of these options, which cost less than $200, produce cafe-quality shots – though neither froths milk.

The Verdict

The Rocket Porta Via targets a particular niche. It’s for the frequent traveler who values great espresso as much as a comfortable bed in their hotel room, AirBnB, or RV – and who has a budget to justify it. If that’s you, then I definitely recommend you look more into this unique portable espresso machine. But if it’s not, the Porta Via is more of a novelty, and you’re better off spending your cash elsewhere.
