After many requests, we were finally able to get all of our dual boiler espresso machines in the same place at the same time — these guys have very busy schedules! But once we cornered a La Marzocco GS/3, Rocket Espresso R58 and Breville BES900XL at our Bellevue retail location, Gail made short work of a very thorough comparison.
First off you may be wondering why you’d choose a dual boiler machine to begin with. One of the primary benefits they offer is that you can control the temperature of the brew boiler independent of the steam boiler’s function. You can also brew and steam at the same time, producing cafe-quality lattes and cappuccinos in a snap. Each of the dual boiler machines we carry offer something a little bit different … here’s a quick overview:
La Marzocco GS/3
Originally designed by La Marzocco for roasters to use to test their espresso roasts, the smallish stature yet commercial grade components have made the GS/3 a sought-after home espresso machine for truly committed enthusiasts. Because it technically is a commercial machine, and can be used in very low volume commercial environments, its shot and steaming performance is most like that of a much larger pro model. The steaming is fierce and forthright, the shot temperature consistent throughout and it features an internal reservoir or plumb-in option. This is the machine for those that appreciate high quality with a little brand cachet.
Rocket Espresso R58
The R58, on the other hand, is a decidedly home-oriented espresso machine with commercial-grade components. Featuring an E61 brew head, a removable PID interface and an exceptionally polished stainless steel case design, it also has a convertible water source and a large steam boiler. While the GS/3 will steam your milk a bit faster, the R58 does enable you to work your milk a little bit, which is perfect for those with mid-range milk frothing skills. If you love the look of polished stainless steel and want a machine that recalls the classic design of early espresso machines, the R58 is a solid choice.
Breville Dual Boiler
Finally, we have the BES900XL, which is Breville’s entry into the dual boiler ring. Like their entire suite of products, this espresso machine is designed from a home appliance perspective — smaller footprint, increased ease of use and some people-friendly elements like an integrated storage tray and the ability to move the machine around on a wheel that’s integrated into the bottom. It has the smallest boiler set of the trio, making its steaming functionality much slower, which can be great news to anyone just learning how to make the fine micro foam necessary for latte art. It’s also the most budget-conscious of the lot, so definitely a great choice for folks who don’t want to drop a few thousand bucks for an espresso machine.
