Built with the commercial-grade components and handmade craftsmanship you've come to expect from Rocket Espresso, the Rocket R58 Dual Boiler offers you double boiler functionality and dual PID temperature control — all in a plumbable, classically styled chrome and stainless-steel housing. Features of the new V2 model include a stronger chassis complete with nylon rails for a seamless drip tray fit, an upgraded magnetic drip tray closure, and an updated control board for optimized steaming and brewing.
Features & Functionality of the Rocket R58 Dual Boiler Espresso Machine - V2
- Dual Boiler: Working independently for both brewing and steaming, the dual boiler along with thermo siphon system design allows for stability in the espresso boiler and increased levels of steam pressure and hot water from the service boiler. The brewing boiler holds 0.58 liters while the hot water/steam boiler holds 1.7 liters.
- Dual PID Temperature Control: Program steam and brew boilers with an electronic remote-control PID that plugs into the side of the machine and does not interfere with the R58's classic styling.
- Commercial Rotary Pump: Quieter than most other rotary pumps, the R58's pump gives you the ability to adjust the pump pressure with the external pressure adjustment controls while monitoring through the pressure gauges.
- Pre-Infusion: To extract the full flavor and aroma when you brew your espresso, the R58 has a dual pre-infusion system encompassing a working piston and static pre-infusion chamber.
- Pressure Gauges: With two pressures gauges on the face of the R58, one monitors the pump while the other monitors the boiler pressure.
- Commercial Parts: Keeping up to its high standards, Rocket made sure that the R58 was made of quality commercial parts, including the E-61 brewhead, rotary pump and heavy weight portafilter (with single and double baskets).
- Plumb It!: Standard with a 2.5 liter water reservoir, a control switch allows you to plumb the R58 right into your kitchen's water line.
- Upgraded and Additional Steam Tip: The steam tip now features a 1.2mm diameter hole, and you get a replacement tip for down the road!
- Handcrafted: Each machine is unique and hand crafted in Italy. Small warps in the case are normal and part of each machine's unique assembly process.

Ask a Question
Really like the fill tray at the front of the GS/3. Filling the R58 could be a problem as it will sit under a cabinet.
Question: does the R58 have any small wheels for pulling out and filling? Seems it would be difficult to pull out to fill the reservoir.
Thanks. The videos with Gail are great!
I tend to use the machine in the morning 1-2 cups prior to going to work and then 1-2 cups in the evening when I'm home, more on a weekend around 5-6 cups in a day. What's the general consensus - leave it on or put it on a timer?
Really thinking about this machine for home use and settings like small events. Seems to be fairly on par with the La Marzocco GS/3, which is surprising with such a drastic difference in price point.
One question I do have concerns pre-infusion. Is this just a built in pre-infusion? Can you control it or set the time yourself?
Any other additional thoughts would be great!
I shared all my experience and posted it on coffeegeek dot com (SCG doesn't allow to post a link of a website). You can find it in the forum under "rocket R58 v2 experience sharing". Hope it will help.
My question is, what should be the proper ritual to making myself a latte every morning? My biggest questions are around cleaning, but here's what I gather so far. Any advice on something I'm missing or something I'm doing that is not necessary would be greatly appreciated!!
1. Make sure there is enough water in the water tank
2. Turn machine on, wait 30-45 minutes
3. Run hot water through portafilter (manual says 1 cup? Do I do this every time??)
4. Pour milk into frothing pitcher (ice cold)
5. Let a little steam out of the steam wand
6. Froth milk and set aside
7. Let a little more steam out of the steam wand and wipe clean
8. Fill portafilter with coffee, tamp, put in machine
9. Lift lever half way for a few seconds, then all the way
10. Watch my espresso being poured (time it, 20-30 seconds for 2 oz), close leve
11. Remove portafilter, dump hockey puck
Cleaning... (this is where i'm most confused about the best way to keep my machine clean)
12. Do I place portafilter back into the machine and run water through it each time?
13. Remove basket from portafilter with tool and wash/clean each separately
14. Do I remove the basket (not sure what this is called, sorry) inside the machine with the rubber ring each time after I make coffee to clean?
The reason I ask about the cleaning is because I found grounds in my portafilter after I had cleaned it and placed it back in the machine from the previous use. I had NOT removed the upper basket/rubber ring after previous use. When I did that, I found grounds stuck around the ring, etc. So should I clean that everyday? Every time?
Thanks so much!
It sounds like everything you're doing is just about right! You don't need to run an entire cup of water through the portafilter each time, and just a little bit for a cooling flush. As far as cleaning, you do not need to remove the brew head gasket (that rubber ring) and brew head screen each time you brew. You can run some water through the brew head and/or rub a clean rag around the edge of the brew head to remove excess grounds after each brew. We also recommend back flushing and descaling regularly. I have included a few links to pages that outline those processes, and we recommend back flushing once every 1-2 weeks, and descaling this heat exchanger once every 2-3 months depending on how hard your water is. Hope this helps!
the R58 comes with an adapter for american plumbing. The connection would be R58, metric hose, adapter, 3/8" or 1/2" american hose(depending on your outlet), valve.
The american side is the same as the flexible hose for your sink. You may want a double outlet valve at your sink to supply your machine, if that is where it will be. One for your sink, one for your machine.
It's really not that hard, once you have the parts in hand. You may want a inline water filter, depending on your water. But, you can add that later.
Since I'm located partly in Europe as well in the US I want to make sure that I can use this machine at all locations.
I appreciate the answers given to previous questions, I'll certainly be following some of the advice given.

- Great machine, a few nitpicksReview by Brent
Quality Price Value
First, SCG is awesome to deal with. They worked with us on the price. They shipped instantly. They were patient and always available as we worked through the plumbing installation (see below) and asked general questions as we tried to figure out the machine, and what wasn't stated in the manual. So, SCG continues to be a stellar company to work with and kudos to them. Their customer service in the buying, negotiating, and set up were all top notch, and we highly recommend buying from them.
As to the machine, it is beautiful and well built. By and large it is an amazingly well designed machine. Even the packaging was top notch. We do have a few nits to pick, but none of them affect our overall pleasure and none of them should be a major deciding factor in considering this machine.
It took us about 4-5 tries to get our grind, tamp and pull to where the espresso "was better than" what we get from our local barista place, according to my wife. So, the machine has a learning curve, like any machine, but delivers a great result. The warmer on top is great, the controls are solid and it makes great coffee. It heats up in about 5 minutes, is appropriately quiet/noisy and it just plain works. Note, you do need to have about a half pound or more of coffee and a half gallon of milk allocated just for your training, which would be true with any new machine Once you get it dialed in, the coffee and frothed milk are fantastic.
We are supremely pleased with the R58 and highly recommend it to anyone looking for a high end machine. So, what are our "nits" we pick? Again, these are fairly minor, but here they are:
1. PID location: The plug-in point for the PID is about the worst possible location. Left side, way in underneath the machine. Since most people are right handed, this is your "inferior" side and you can't quite reach it by touch. So, you have to get your head down on the counter and carefully insert the PID Pin connectioh or risk bending a pin. It seems like an afterthought location. How about putting it on the upper back or closer to the edge on the right or somewhere easily accessible?
2. Plumbing: SCG now includes a metric/english brass adapter which is a good thing. However, the adapter comes stuck to the inlet valve for convenience, but not water tight installed. They don't tell you this, and it looks installed. There are no instructions on exactly how the inlet, hose and adapter need to be configured. It took us 2 trips to the hardware store and two calls to SCG to get it right. A one page instruction sheet on how exactly to connect the various parts with a minimum of mistakes should be included.
3. Instructions- The included video is essentially useless. It is nothing more than a video of the "how to use the machine" section of the manual. The manual doesn't include a bunch of useful information. For example, every picture in the manual shows the right side pressure gauge as "working", at 1 bar. However, when resting there is no pressure to the brew head, so the right side gauge is at 0 until you pull. Well, given the manual always looks like that gauge should work, we thought something was wrong. Manual should explain the brew head pressure gauge only shows pressure when you pull a shot. There are other similar discrepancies or lack of info in the manual.
As we said, these are pretty small nits and we still would buy the R58, even knowing the "nits." We are very pleased, and way over caffienated from enjoying the machine so much! (Posted on 9/2/2014)
- a real machine for real espresso connoisseurs at home.Review by Charlie
Price Value Quality
So here's the verdict: Skip the "pressure ramping" gimmick or any of the other nonsense they're trying to upsell. This machine gets it right- perfectly right. It looks great in my kitchen. It outputs EXACTLY the quality I would expect from Intelligentsia, Vivace or any of the other "synesso shops" that have popped up in Los Angeles lately.
The R58 to me is great coffee without hipsters. If I had to buy it again I'd say the La Spazial "Dream" would be a candidate- though as a beginner the lack of volumetric on the R58 force me to time shots and measure volume, which forces me to learn it correctly. And if I were running a cafe... the GS/3 would be the "one"- just because of its 20 amp and volumetric- allowing you to "fire and forget". (Posted on 4/23/2014)
- An Almost perfect Espresso Machine. Beautiful! Review by Steve San Diego
Quality Price Value
I keep the PID controller connected, and monitor the recovery until I get a good feel for the machine. The machine's brew boiler recovery time is exceptionally fast, and is about 15-20 seconds. Nothing like a 1400 Watt heating element. That's less time than it takes to knock out your portafilter grounds and then refill it. Because it is 15 amp only machine, with brew boiler priority over the two boilers, it has a minor quirk. One boiler can run at a time, but they are quickly switched on and off by an internal microprocessor to maintain temperature stability, and to keep the total instantaneous current load below 15 amps. You can steam milk first, and go right into brewing coffee, as the brew boiler gets priority from the machines's internal Microprocessor. If you choose to pull your shots first, pause for about 30-45 seconds before you steam milk. That gives the machine time to recover the brew boiler temperature, at which time it switches the Steaming boiler back on line. If you don't wait, you will run out of steam midway through steaming your milk. Once again, monitor the PID controller and wait for the default display of the brew Boiler to reach its preset temperature. It's set at 105C at the factory. That a good for a dark roast, but I use Lavazza Top Class, a medium roast, and prefer a setting of 106C. My experience and preference is higher Brew temps for lighter roasts and vice versa. Anyway, it recovers quickly, and you're off to steaming your milk.
It makes a lot of steam. I switched the tip from the 1.5mm holed tip to the provided 1.2mm holed tip. A small crescent wrench works well. It will heat a small carafe of milk a little too quickly to make good foam with the larger tip. For larger quantities, say 16 ounces + when you're making multiple lattes, use the larger 1.5mm tip. For best results and to avoid overly frothy milk, Don't angle the tip at first, and keep it aligned vertically just below the milk's surface, allowing a small hiss of air to be injected into the milk, until the temp is between 100-110F, then submerge the tip at an Angle of about 15-30 degrees, and let the milk swirl until it's about 150-155F. No more than 160F to avoid scalded milk.
Is this machine better than a single boiler or a single boiler hear exchange machine? Yes, way better. It is far superior to my Andreja Premium, which I've owned for 10 years. It is far better than my 1st generation Izzo Duetto, which I thought that machine was heavily flawed and unreliable. That's why it's now a 3rd Gen Machine. I understand the newest version of the Izzo Duetto rocks, but it still suffers from lack of cup clearance between the brew head and drain tray.
Expensive yes, but ITS WORTH IT! Did I mention it's very beautiful sitting on your counter! (Posted on 2/8/2014)
- Great Machine Overall. Pay attention to plumbing!Review by J White
Quality Price Value
External controller - I don't intend to fiddle with it much except to adjust the temp for new coffee blends and occasionally turn on the steam boiler, so I like the fact that the classic styling is not ruined with a glaring digital display. One of the main reasons I picked it over other PID controlled machines, including the Vetrano 2B
Switchable Steam boiler - 90 percent of the time this machine is used for espresso but I do make milk drinks for visitors and the kids, so I like that I can turn that on and off. This is another of the deciding factors for me. FYI the time from cold to full steam is about 6 minutes.
Easily removable drip tray - Easy to remove and clean and the magnets ensure that it stays in place.
Overall aesthetic - I just really like the looks of the cup rail. It looks both elegant and sturdy, and looks like something from a professional machine. It's a petty thing but for some reason it stands out for me. The gauges are large and readable but not out of place. Little things like the real screwed on name plates, where most machines in its class have stickers, and the disk covering the expansion valve drain. And once again no glaring PID display.
Quality accessories - The portafilters and tamper that came with the machine are better quality than those provided with the other machines I've owned. The included smaller hole steam tip was a nice touch.
Loud - For a rotary pump machine it is suprisingly loud. It has a buzzy sort of sound that seems like it might be from parts vibrating together. In addition the pump is just louder than it was on my first generation Vetrano, and has a whine when it comes up to the full 9 bar pressure. It's not horrendous but not what I expect from a rotary pump machine. I would almost knock a quality star from it for that.
Drip tray size is ridiculous - It is so shallow front to back that if you don't have a portafilter in the group you WILL have water everywhere, for example when you are cleaning the group. Of the three machines I've owned, it is the worst by far. In addition it is pretty shallow, if you are not plumbing the drain you'll be dumping it a lot (but if you're a neatnik that might not be a bad thing).
Controller connection - It is described on this site as a USB connection, I wish it was. It is actually a 25 pin serial connection that can be tricky to connect if you are not looking directly at it, and if you're a ham handed person you could potentially bend pins.
British Plumbing fittings - This is a real gotcha! The water fitting on the machine and on both ends of the supplied hose are a British fitting. You are simply not going to connect this with anything in your house without an adapter, and you will not find one at the local hardware store. One can be purchased from Seattle Coffee Gear separately. My only knock against SCG. Some sort of adapter to US standard plumbing fitting could only cost a few bucks at cost, pitch one in the box SGC! I was really frustrated when I found this out and had to wait for one to be mailed. To their credit SGC did send an adapter out for free, but it would have saved me some time and frustration if they had just done that up front. Good thing it has a tank!
I am not an expert on milk drinks but I found that using the included optional steam tip did make it easier to froth smaller amounts of milk, which is all I ever do, and it seems to have more than enough steam power.
Overall I love this machine and I'm happy with the purchase. It looks great, and the build quality seems excellent. Most importantly, it makes a great espresso. I would definitely buy it again and would recommend it to others. Even with it's flaws, I think it is a five star machine. (Posted on 2/7/2014)
- Very nice machineReview by Bill
Price Value Quality
In short, really like the machine. The build is very solid. The valves for steam and hot water are very positive - no cranking down hard to close. And, most importantly, the temp and pressure are always consistent. So any 'defects' are my technique as this machine really seems to be able to make a great cup.
I put the machine slightly low on price rating for only one reason - I suspect a cheaper machine could make just as good a shot. However, the build quality and design are probably what you are paying for and those seem worth it if you've got the cash.
One minor complaint ... Rocket claims the machine was set at 9bar out of the factory. Maybe it was, but it wasn't set there when it got to my house. My first shots were barely getting to 7bar. Now I'm one of those geeky engineer types so I was pretty sure I could figure out how this thing should work and, even with the blind basket in the portafilter, it couldn't get past 7.5bar. So I pulled out my tools. Turned out the locking nut on the pump adjustment under the machine was barely tight. So, either they never got it set or they didn't lock it down and things moved (not sure I buy that). Anyway, a few 'turns and tests' later and I've got it dialed in (actually, may be a little high but close enough). If you're not handy, this might be a bit of a pain. So, if you get one, check the pump pressure. On the upside, the adjustment is pretty easy to make.
All in all though, great machine. Consistent performance. Never have to wait for hot water, steam or a pull. With that plus the build quality, I would recommend this to others. (Posted on 12/22/2013)
- High quality, serious espresso machine with a few flawsReview by Bruce
Price Value Quality
Cons: 1. Drip tray too small - one is constantly cleaning up spillage due to too small a surface area for normal extraction procedures. 2. Absence of reservoir gauge. 3. Absence of timer clock. 4. I'm still having trouble getting a nice, dry "puck" with extractions. 5. Configuration of steam wand, water wand, group-head and lever results in crowded ergonomics - one has to carefully negotiate a path to the lever to initiate an extraction. (Posted on 12/5/2013)
