Dual boilers are where it’s at when it comes to controlling the temp of your shot while also sporting steaming functionality that is almost embarrassing in its ferocity.
These little babies come in variety of formats and price ranges, and Gail shows us models from Rocket Espresso (the R58, what!) and Quick Mill (the QM67, what!) to show you how their form, function, tech specs, internals and performance compare.
In the market for a big baddie? Is having control over your brew temperature and/or steaming enough milk to serve up cappuccinos to a small army a high priority for you? If yes, you probably should check out the Rocket Espresso R58 or La Marzocco GS/3 double boiler espresso machines.
Look we don’t want to tell you how to live, but we do care about you. So we’ve put these two popular machines side by side to show off their features, tech specs, internals and performance. Watch Gail walk us through this glorious adventure!
For years now, we have had a deep and abiding love for Rocket Espresso‘s heat exchange machines, so when their new dual boiler model, the R58, hit the market, you know that a dance party ensued. But aside from sharing some of the aesthetic principals of its Hx counterparts, how does the R58 compare? And why would you choose one style of machine over the other?
In this video, Gail does us the sweet favor of breaking it all down for us. She talks about functional and feature differences, why you’d want a dual boiler or a heat exchanger and then crafts cappuccinos on both styles of machine to demonstrate how they compare, performance-wise.
In The Great Espresso Machine Wars of 2011, the bloodiest battle was that between the rotary and the vibratory pump. Seriously; things got real.
You didn’t hear about it? Well, it’s really not something we like to rehash — and there were definitely lessons in there for all of us. But even though we’re not yet prepared to talk through it (too soon!), we don’t mind taking a couple of pumps apart and asking one of our favorite engineers for his input on how these bad boys work.
Watch as Gail and Bill Crossland go through the internals of a vibratory and rotary pump, discussing how they work, why you might select one over the other and what to expect from them. Then we measure the sound differential between the vibratory pump on the Rocket Espresso Premium Plus and the rotary pump on the Rocket Espresso Evoluzione to learn if the whole ‘it’s quieter!’ argument really holds water. Finally, we pull shots to see if there is a noticeable, practical difference in flavor between the two styles of machines.
Heat exchange espresso machines offer simultaneous brew and steam functionality by employing a large steam boiler with an embedded brew boiler and a dual pump. They’re easy to use and work well for the majority of home espresso enthusiasts who aren’t interested in dialing in and playing around with different temperatures.
We pit these two heat exchangers up against each other to see how their shots compare. Does the well-loved E61 group head make a discernible difference in the shot quality? Find out in this blind taste test!
If you want to make excellent espresso drinks at home, a double boiler machine allows you to demonstrate both your dedication to the cause and your enviable skills. Featuring separate boilers for steaming and brewing, these machines offer excellent temperature control and simultaneous brew/steam functionality.
If you drop serious coin on your home espresso setup, will there be a practical performance difference? What if you spend more on your espresso machine than your grinder or vice versa?
We asked Gail to test out an entry level (Capresso Infinity) and a prosumer (Mazzer Mini E) grinder with an entry level (Krups XP5280) and prosumer (Rocket Giotto Evoluzione V2) espresso machine to see how they compare. Do you get a better shot using a high end grinder with an entry level machine? What about an entry level grinder with a high end machine?
Our long love affair with Rocket Espresso has been taken to a higher level with their newest addition, the R58 dual boiler espresso machine. Featuring separate, insulated copper steam & brew boilers and a removable PID interface to control the steam boiler on/off, brew boiler temperature and the water source (either the internal water reservoir or plumbed-in), the R58 also has a dashing case design and a beautiful stainless steel cup surround.
Seriously, we’re not sure if it can get much better. We need a moment. While we collect ourselves, check out Gail’s from box-to-cappuccino introduction to the R58.
