Quick Summary
Quick Mill QM67 Evo
With a large water tank and commercial espresso machine technology, the Quick Mill QM67 Evo is perfect for the prosumer's home kitchen or office. If you're looking for cafe quality at a lower price, it's a solid choice.
Rocket R58
Boasting powerful steaming, commercial grade parts, and plumbing options, the Rocket R58 can support a small business or become your favorite home espresso machine. It's the best bet if you're a restaurant owner or you require a direct connection to your water line.
Similarities
Semiautomatic Machine Type
The Quickmill QM67 Evo and the Rocket R58 are semiautomatic machines with levers for manual brewing.
To begin brewing, the user pushes the lever into position. Once the correct volume has been achieved and the espresso shot looks ready, the user pushes the lever in the opposite direction to end the brew cycle.
Semiautomatic machines take a certain amount of skill to operate, as opposed to automatic machines that dispense a programmed amount of water.
On the other hand, you’ll gain greater control of the brew process. You can be as creative as you want and pull longer or shorter shots on demand.
Output Capacity
Capable of making 20 espressos per hour, the Quickmill and Rocket models are high-performance machines for the home environment.
This type of output capacity is also suitable for many small businesses with a lower volume of espresso production.
When you’re shopping for a machine for business purposes, you’ll want to calculate your average espresso production volume to select an accommodating machine.
Dual Boiler System
Brewing and steaming require different temperatures. For this reason, many espresso machines have systems specially designed for simultaneous brewing and steaming.
The Rocket R58 and Quickmill QM67 Evo have dual boiler systems (a boiler dedicated to each function) to provide stable brewing and steaming temperatures at all times.
One of the advantages of this system is steady steaming. It will also allow for quick brewing as it minimizes the need for flushing the group head before pulling a shot.
PID Temperature Control
With PID temperature controllers, these espresso machines create advanced thermal stability in addition to the ability to adjust group boiler temperatures.
PID controllers are often favored in industrial equipment for their dependability. They use an algorithm to continuously monitor variables and recalibrate for better temperature regulation.
The Quickmill QM67 Evo temperatures are adjustable in increments of one degree Celsius or Fahrenheit.
You can set the Rocket R58’s temperatures in Celsius or Fahrenheit with the easy external controller that provides other options like multiple language settings.
E-61 Commercial Group
An E-61 commercial group enhances the performance and thermal stability of these espresso machines.
The group shuttles water between the boiler and the group head at a constant rate to keep the brew temperature optimal.
Temperature stability can improve consistency from espresso to espresso and enhance results.
Pre-Infusion
In espresso machines with pre-infusion, there is an initial phase of brewing that ensures full extraction and well-developed flavor in the espresso.
During pre-infusion, water is released into the group head to gently permeate the entire coffee puck. This guarantees that no coffee particles are left unextracted.
The Quickmill QM67 Evo and Rocket R58 both come with automatic pre-infusion to make it easy.
Pressure Gauges
These espresso machines are equipped with two important pressure gauges that increase close monitoring of internal functions.
Via the brew pressure gauge, you’ll be able to see how many bars of pressure the pump is applying during the brew process. If the pressure is off, it’s likely time to make adjustments to your brew ratio.
The boiler pressure gauge gives you a reliable market of when it’s time to brew and steam, which is particularly helpful when you've just turned the machine on and you're waiting for it to warm up.
Hot Water Spigot
With built-in hot water spigots, you can make Americanos on one machine and avoid the need for using multiple pieces of equipment.
Espresso machines without hot water spigots can be economical due to limited features, but making Americanos (or teas) necessitates an external hot water device.
In an office environment, the addition of the hot water spigot is usually helpful for space-saving reasons alone.
Cup Warmer
Beyond providing a place to stow espresso cups, the warming areas on top of these espresso machines make toasty cups.
Preheated cups keep beverages warm for longer periods of time so that you can enjoy a hot latte at a more relaxed pace.
Without a cup warmer, if you want a preheated cup, you add a splash of hot water from the spigot as early as possible in the drink making process to reduce the wait time.
Since your cups will already be warm with the Rocket and Quickmill models, making drinks will be quicker and easier.
Key Differences
Plumbing Options
The Quickmill QM67 Evo is a pour-over espresso machine with a water tank that is manually refilled as it gets low.
Combining the best of both worlds, the Rocket R58 comes with a water tank for manual refilling as well as the option of plumbing the machine into a water line. This way, you’ll get a direct feed and can skip filling the water tank.
While a manual reservoir does allow you to use the machine away from a water line, a plumbed-in machine increases efficiency and cuts down on the daily maintenance of a water tank.
Pump Type
With a rotary pump installed, the Rocket E58 is quiet. Owners of espresso machines with rotary pumps find these parts to be long-lasting, which is a definite plus.
The Quickmill QM67 Evo’s vibratory pump is a little louder, but the machine does come with special technology to make it quieter than the average vibe pump.
While the rotary pump offers longevity, the vibe pump tends to be a low-cost option that’s easy to replace.
Water Tank Size
Both of these espresso machines have decently sized water tanks that home users and many small business owners can utilize.
The Quickmill QM67 Evo’s 3-liter water tank is a bit larger than the Rocket R58’s 2.5-liter tank.
This is a good thing as the Quickmill model operates solely with the water tank, as opposed to the Rocket model, which can switch over to the direct-connect function.
Steam Boiler
There are some differences in these espresso machines’ steam boilers that will create slightly different effects.
The Rocket R58’s 1.8 liter insulated copper steam boiler is powerful. Its copper construction supplies corrosion resistance and antimicrobial properties.
The Quickmill QM67 Evo’s 1 liter boiler with T.E.A. coating provides extra protection against the possibility of metal leaching.
In terms of steam power, the Rocket will have more, but the Quickmill has plenty of steam reserves for typical usage at home or in a low-volume environment.
Quick Mill QM67 Evo Hinged Water Tank Lid
A hinged lid on the Quickmill's water tank offers immediate and super fast access (the Rocket R58’s lid must be completely removed to get to the water tank).
It’s one of those design details that makes everyday operation just a little bit smoother and easier.
Rocket R58 Metal Tamper
The metal tamper that comes with the Rocket R58 has the proportions and weight needed to apply adequate and even pressure when tamping.
Better tamping leads to better extraction. An uneven tamp or too little pressure can throw off the results and create underdeveloped (or over-extracted) flavors.
Another factor that makes baristas love metal tampers is the aesthetic. There’s just something about a sleek metal tamper that a plastic one doesn’t deliver.
Price Considerations
We carefully consider every aspect of our espresso machines with different budgets in mind to bring our customers the best equipment at the lowest prices.
We offer the Quickmill QM67 Evo at Majesty Coffee for $2,195 and the Rocket R58 for $3,000.
So Which Should You Buy?
As home espresso machines, the Quickmill QM67 Evo and the Rocket R58 provide excellent performance and the opportunity to hone your craft with manual dosing.
The Quickmill model is a great option for beginners to cut their teeth on as it’s a little more pared down in functionality while offering professional results.
Both of these machines are also ideal for offices looking to ditch the middleman and serve cafe-quality espresso beverages at work.
When it comes to small businesses like restaurants, the Rocket model is a solid choice. There's a bit more power and versatility with features like a larger steam boiler and the direct-connect function.
The direct water feed is especially beneficial during peak hours when back-to-back coffee orders are coming in.
As far as your choice for a home machine goes, we think it will come down to personal preference, but you’ll likely be very happy with either. These machines aim to please.
