Hand-built in Seattle, WA, Slayer machines are known worldwide for their signature style, excellent build quality, and of course, their unique and rewarding approach to espresso brewing. The single group machine packs the Slayer pedigree and patented technology into a compact and beautiful package - and with their myriad customization options, you can truly make it your own.

Built on Slayer V3 grouphead technology, the single group is built for low- to mid-volume commercial environments, or very lucky homes and offices. It's got a three-stage paddle group for optimal flavor profiling, a saturated grouphead for consistent heat management, a 58 mm bottomless portafilter and shot mirror, and even a new Teflon-coated dispersion screen that both provides a smooth and steady shower of water and is a breeze to keep clean.

Built to Impress

Under the hood, Slayer's patented needle valve is the master of your extractions, allowing you to dial in your desired pre-brew flow rate for precise control over your shots' flavor. An expansive set of electronic controls featuring a glass touchscreen interface allows the user to set everything from brew boiler temperature and steam boiler pressure, pre-brew timers for semi-automated brewing, a power-saving weekday and weekend schedule, to tweaking the brew pump pressure and PID parameters. The PID-controlled 1.1 L brew boiler with a pre-heat coil ensures shot-to-shot temperature stability, and a digital pressure transducer keep the 3.3 L steam boiler running at the optimal pressure to the tenth of a bar. Speaking of steam - you'll not be left wanting, with a commercial-style steam wand with multiple steam tip options. A 20 ounce pitcher of cold milk will find its way to warm and silky microfoam in seconds, just like on a larger Slayer, or other commercial machines. And with a 1300 W heating element on 120 V power, steam production won't slack even across back-to-back milk drinks.

Advanced Espresso

Straight espresso enthusiasts, be prepared for the whole new level of deliciousness that awaits you. Slayer doesn't pull shots like most machines, to the great benefit of your taste buds. Rather than utilizing a line-pressure preinfusion, the needle valve restricts the flow rate in Slayer's pre-brew setting. This allows low-flow brewing to fully saturate the puck and begin extraction, while ever so slowly ramping up pressure. Flip the paddle from the center stage pre-brew over the left stage full-pressure brew, and you'll get the proper 9 bar extraction pressure and full flow through the puck. Want to ramp back down to the pre-brew flow rate? Just switch the paddle back to center, and you can dial in the flavor of your extractions however you wish. You can enhance the sweetness of your shot by extending your pre-brew time, or go for a touch more brightness by switching to full pressure early, then ramping back to pre-brew, and finishing again at full pressure. A syrupy, delicious, and well-rounded shot is now even more accessible, and old standby favorites can find even more depth of flavor when dialed in.

Slayer single group

Ordered machine on Nov 24th, received on Dec 11th. Machine is built with attention to detail and looks beautiful in the kitchen. Espresso is sublime and steaming power seems endless. Initial setup takes a bit of patience but well worth the time. Ryan has been great through with the sale and follow up process!

This brings the wow factor!

I've had my eyes on this machine for quite some time, and have done extensive research. Constantly debating whether this would be too much machine for me, is this really necessary, would I be happier with a lesser machine (Linea Mini, Vesuvius, used La Marzocco or Synesso), etc? Mind you, I started with a Breville Barista Express, then to a Rocket Evoluzione v2. I pulled the trigger on this machine because of the unmatched ability to "Flavor Profile", not to be confused with pressure profiling. I love the idea that I can control the flavors being extracted from the expresso without changing any of the other variables like grind size and dose. Right away, this machine is stunning! The Peruvian Walnut looks great and has the high quality feel. The portafilter has a counterweight to give it a really nice balance. The size is perfect for home use, definitely does not take up a lot of space and will fit very easily under any cabinets. It's nice that you can easily just pull the cup tray off to adjust the needle valve, but because of the ambient heat from the boilers, the handles get extremely hot! So, you will need a towel or gloves to lift it if the machine is still on. The steam power is very strong, I'd say it's on par with most commercial espresso machines on the market. It is a "Burn me" wand, so be careful and use a damp towel, as you always should. Those considering this machine know that you need a grinder that can grind very fine. I currently use a Mahlkonig K30 Vario and it does not grind fine enough, so I'll be purchasing a Compak E8 or E10 (recommended by Slayer) very soon so I can utilize this machine to its full potential. Keep in mind that choosing the right grinder for this machine is crucial. Slayer has the best customer service, they've been able to answer all of my questions, some have been very very specific and they respond right away! Because of this, I completely trust their recommendations, they won't stir you wrong. Since these machines are drop-shipped from Slayer, they have each and every one bench tested before leaving their facility to be sure it's in perfect working order. They even supply a 3/8" compression fitting to 3/8" OD, so all you need is the 3/8" tubing and you're ready to go! If I had to change anything, it would be to have the steam wand on the other side where the hot water tap is, or make it interchangeable. Maybe it is and I just haven't figured it out. =P This is just my own personal preference because I hold the pitcher with my left hand. It is more difficult to reach over the huge steam wand with my right hand to turn off the steam. I guess I'll have to adjust and learn to steam with my right hand. Also, the touch screen on the UI is a little difficult to use. I've noticed that you need to swipe your finger across in a slow smooth motion for it to detect. It's not nearly as responsive as your smartphone so be patient with it. The UI is nicely placed on top by the cup tray, instead of underneath the drip tray like the 2/3 group machines. This is great because you can keep on eye on the brew temp, steam pressure, pre-brew and full-brew times. Match this with the Acaia Lunar scale to automatically monitor yield weight and flow rate and you feel like you have control over everything! It's a match made in heaven! Overall, I'm thoroughly enjoying it, it's such a beautiful piece of machinery. The temperature is very stable, strong steam pressure, easy to use once you figure out the quirks. I still give this machine a 5 star review because there's no machine that's perfect and they will always have their pros and cons. I feel like the pros far outweigh the cons, and I'm extremely happy with my purchase and my experience with Prima and Slayer! Would I recommend it? Yes, and no. Yes, if it's in your budget since it's a huge investment. It takes a knowledgeable person to use this machine and therefore, not for everybody! If simplicity is your cup of tea, I would suggest an AV machine, or something like a Linea Mini and still be able to give you that professional feel and power. This machine is more for people who like to experiment with flavors, and have full control over their machine. It can be used for small to moderate volume cafes since you can use Auto Pre-Brew to save a specific profile. Great job Slayer and thank you Prima Coffee!

Breaks constantly

Bought this less than a year ago. It breaks constantly. Ive had to replace the pump assembly, the pressure gauge and the pressure release valve on the steam boiler. Ive had service people out to fix the overflow tube that takes water from the actuator to the tray after each use, it leaks constantly because its badly designed and kinks and stains the counter, but it still leaks, there‰Ûªs nothing they can do. I have to keep a dish under the machine to catch the water so the one thing it used to do well - look nice- no longer applies. All told Ive probably had service people here on 6 occasions, at close to 1000 dollars in labor. And despite all that it still doesn‰Ûªt work. Just today the actuator has spontaneously stopped running water AGAIN, for the second time in a month, its totally unusable. In my conversations with employees at a local coffee chain that uses slayer, they‰Ûªve had chronic problems and are just waiting till the final death knell of their machines before they switch. Maybe I just have a lemon, but it doesn‰Ûªt sound like it. Get something else.

Makes Everyday Better

I purchased the machine as a demo model. I was told the pump needed replacing due to an upgrade. I live in Portland, OR. I drove the machine up to the main office in Seattle. They put in the new pump for me and showed me how to replace every part that needed replacing on a regular basis. Best customer service ever. My only complaint is now that I make the best espresso drinks at home, it’s difficult going to other baristas and finding them wanting.
