We have written before about the no love lost between superautomatic espresso machines and oily, dark roasted coffee beans, but when we got a machine in the repair center last week that was caked to the gills with coffee cement, we just had to film it and show you what we’re talking about.
Watch Gail take apart the grinder of a Saeco Vienna superautomatic espresso machine and show what happens over time to the internal grinders on these machines if someone is using super-dark and oily beans. We definitely recommend sticking with a lighter, drier roast for the long term health of your machine — and now you’ll see why!
We’ve said it before and we’ll say it again: Temperature, temperature, temperature. For truly great espresso, there is a fine balance between too hot and not hot enough — and maintaining the temperature from portafilter to lips is very important. Oh yes, yes it is.
The first step is to let your machine warm up all the way; often, folks think that as soon as the light goes out (generally around 1 – 2 minutes after turning it on), the machine is ready to rock. Not so! In fact, all that means is that the machine has reached ideal boiler temperature, but all of the other parts of the machine have not, so if you pull espresso right at that time, the water is going to cool significantly as it travels through colder apparatus to reach your cup. Depending on your machine, we recommend waiting anywhere from 10 – 30 minutes to allow your machine to reach an even heat.
Next step is to pull some water through the system to warm up the brew head, the portafilter and — if it’s a heat exchange — the copper tubing that pulls water from the reservoir to the brew group. Let it run through and fully warm up all the metal components.
Finally, make sure you’re pulling into a preheated cup; you can easily preheat by using the cup as the container to catch the water you just pulled through the brew group, or you can keep your cups on top of your espresso machine and let them toast as your machine warms up.

With so many different kinds of espresso machines on the market, researching which is the best for you can sometimes feel like popping open a big ol’ can of worms. Superautomatic or semi-automatic? Single boiler, heat exchange or double boiler? Is the E61 brew group really that great?
Our goal here at Seattle Coffee Gear is to provide as complete of a picture as we can about as many machines as possible. We read through user reviews to develop general pros and cons, have our techs test out the machines, experiment with different grinders to see how they perform with different machines and, ultimately, drink way more coffee than we should. All of this informs our YouTube videos, the writing we do here, our product descriptions and — one of the best resources we have — our Selecting an Espresso Machine Video.
If you’re just learning about espresso machines and aren’t sure what will meet your needs and budget, this video is a great place to start. We’ve organized the different machine classes by price range and compared their performance against each other, so you can see technical facts like how hot they brew or which type of pump they have and more subjective assessments such as the ease of use or quality of shot.
We’re constantly updating and adding machines, so definitely check out updated Crew Review videos once you hone in on the right machine for you.
We’re all more conscientious these days about our environmental footprint — what we do every day and how that impacts the world around us — and our pocketbook. What started as a random inquiry every now and again eventually developed into a dull roar…people want to find a way to keep their fully intact machine out of a landfill.
So we developed our Recycling Program to fill this need: we will break it down into all of its components, reuse any parts that are still good and then recycle most of the rest.
If you’re interested in the program, just contact us and let us know the make, model, age and condition of your machine. We’ll get back to you on how to deliver your machine to us. Feel good when you choose a new, upgraded model that your old machine is still being green!
We’re all looking for ways to stretch our loot a little further these days. Keeping your home espresso machine in excellent condition means you can enjoy high quality espresso for years to come at a significantly reduced cost than what you’d pay at a local cafe.
To that end, our techs offer a Tune Up service for both superautomatic and semi-automatic espresso machines. This is a popular service that we wanted to share with more people around the country (yes, you can ship your machine to us for this service) and so we asked Gail to describe how this service works, what we do, etc.
For those of you not into watching videos or if you’d like to contact us about having your machine tuned up, we have full detail on the service and a contact form here.
We admit it, we’re guilty. We thought that size did matter with regard to boilers on a semi-automatic espresso machine — namely, that two boilers was better than one. The hierarchy in our mind was:
- Single Boiler: From the Saeco Aroma to the Rancilio Silvia, the single boiler is a great little semi-automatic espresso machine that requires special attention to boiler temperature so that you’re brewing well below the steaming temp and not burning your espresso. With a single boiler, you’re not able to brew and steam at the same time — we recommend steaming first, then brewing.
- Heat Exchange: Instead of pulling your brewing and steaming water from the same vat, per se, heat exchangers like the Rocket Giotto Premium Plus or Quick Mill Andreja Premium transports fresh water from the reservoir through the boiler via a copper tube that is specifically designed in length and girth to heat the passing water to the optimum brewing temperature, not the steaming temperature. We are talking about a nearly 40F degree difference, so this improved temperature regulation significantly upgrades the espresso shot quality. This functionality also allows for simultaneous brew and steam.
- Double Boiler: Only a few models on the market, such as the La Spaziale Mini Vivaldi or Izzo Alex Duetto, feature absolutely separate boilers for steaming and brewing, which allows you to maintain disparate temperatures and brewing and steaming at the same time. You can generally program your preferred brew boiler temperature on these machines and, in the home espresso machine space, they generally feature a quicker recovery time than their heat exchange counterparts.
So, based on those assessments, you’d understand why we were confused by the more is better idea — that maintaining temperature is significantly easier when you’ve got two separate boilers doing their own thing.
However, in our recent research and education around the new line of commercial Faema machines we’re now carrying, we learned that our hierarchical view was incorrect — in fact, Italians haven’t been using double boiler technology for decades, believing that the heat exchange technology provides for significantly improved espresso due to one major reason: It’s alive!
Boiler water is considered ‘dead’ water because it’s sitting in a little metal unit cooking away. Over time, this results in a significantly increased alkaline content in the water (ah yes, that lovely scale we keep talking about so much) and a mineral imbalance in extraction. Basically, the flavor’s different.
Since heat exchange machines are continuously cycling fresh water through their siphoning system, they have an improved mineral balance and cannot become stale like the water in the double boilers might. So the flavor is significantly better and, therefore, preferred by connoisseurs the world over.
If you’re in the market for a ‘prosumer’ machine, this is definitely important information for you to mull over. Not only is the footprint smaller on a heat exchange machine vs. a double boiler, but it just might pull a better shot.
While single boiler machines are extremely cost effective, they do suffer from wide temperature fluctuations which can result in poorly extracted espresso. As such, the technique for ‘temperature surfing’ was developed by home espresso enthusiasts and you can watch as Gail goes through the process on a Rancilio Silvia. This technique can be applied to any single boiler machine — such as the Saeco Aroma, Ascaso Basic or Dream and any of the Gaggia semi-automatic espresso machines.
Does your bipass doser sometimes seem a little faulty? We occasionally get reports from customers that their older Saeco or Gaggia superautomatic espresso machine (which features a metal burr grinder instead of the newer ceramic grinder found on the most current models) is producing nothing better than dirty water every time they try to use pre-ground coffee in the bipass doser.
The cause? Static cling. In really dry climates, the static can build-up in the metal burrs, so when ground coffee is poured into the bipass chamber, it ends up clinging to the sides or going around the brew group instead of landing directly into it.
The best way we’ve found to counteract this issue is to add a little bit of moisture to your grounds before you pour them into the bipass chamber. The moisture and extra weight will make sure the majority of the grounds land in the right place and that you’ll brew a great shot of espresso.
