"Steaming with this revolutionary steam tip creates the finest, most silky cappuccino foam I have ever served at Vivace." - David Schomer
At Espresso Parts, we are always looking for processes that will create a better preparation method and higher quality coffee beverages. As a result we have been honored to be a part of many special products related to the furtherance of specialty coffee quality. The Sproline by SS&W is just one of those projects, however it is also one of the most compelling.
The work related to these items is that of Shojiro Saito, our partner in Japan. Several years ago he created the idea of brewing high quality teas on an espresso machine. While the idea of brewing tea on an espresso machine was not new itself, the processes created by Shojiro to create a quality tea beverage were. When introduced to Espresso Parts, we asked the question, about coffee and how the system might work. A year later Shojiro responded with what we now call the Sproline of Screens, and steam tips.
So, what is the process used to create the incredibly tight bubble structure created by these tips? It is called Hydrodynamic cavitation.
Hydrodynamic Cavitation occurs in liquid when bubbles form and implode in pump systems or around propellers. Pumps put liquid under pressure, but if the pressure of the substance drops or its temperature increases, it begins to vaporize just like boiling water. Yet in such a small, sensitive system, the bubbles can't escape so they implode and this implosion creates what we refer to as nano bubbles. This process as it relates to Tea and coffee milk steaming was recently provided a patent in Japan, to our firm SS&W.
What is unique about our method is that we have created high and low pressure zones on the output side of the tip. The resulting high and low-pressure zones create Hydrodynamic cavitation and thus an implosion of the smaller micro bubbles created when steaming milk. The bubbles create such a tight bond that the structure creates a glossy surface to the milk that holds shape and pattern for a very long time. The effect of the nano bubble structure also keeps the gas bubbles of the coffee from escaping the surface of the beverage, and damaging the latte art and/or foam structure on top of the beverage.
Independent Coffee Houses and Baristas around the world are just learning of our new methodology, and are blown away by the quality of the milk created by these tips. Espresso Parts is proud to work with not only Shojiro, but all that who continue to look for additional methods that create quality within our industry.
Sproline Foam Knife 1 Steam Tip will fit Commercial La Marzocco and Slayer Espresso machines. It will also fit directly onto the stock Nouva Simonelli 'Oscar' model steam wand.

While Espresso Parts appreciates those with Home Espresso Brewing equipment, we are unable to determine fitment of our parts to the various model home and semi commercial espresso machines. We hope within the year to develop products that will address this market.

Works awesome on my HX machine. I had to remount my steam wand assembly at a bit of an outward angle to achieve the necessary 45-55 degree insertion angle that this steam tip requires. After a few weeks of use I've got incredibly consistent microfoam that holds for a long time. I'm using it in conjunction with the La Marzocco GB-5/FB-80 wand.

Makes a huge difference on my la Marzocco G/3 I use nonfat milk and its the only way to make the right milk texture

I am using this foam knife steam tip on Nuova Simonelli Oscar. You should be able to realize the "difference" as soon as you start to use this tip.

Takes a little getting used to, as this works very differently than other tips. Once you figure it out, the results are awesome.

This tip works amazingly well on my GS3. The foam is really tight and designs hold for a really long time. With practice, you can do tiny amounts of milk (cortado and macchiato).

Using it on my Astoria SAE/JUN 1 group and it works great. Had to replace my steam arm with a La Marzocco 'GB-5/FB-80' Steam Wand (MZ_T2001) but that was easy and definitely worth it. Took just a few times to get the hang of it. Now producing better micro foam than I ever have.

The foam knife tip makes a really great addition to the GS/3. It is so easy to make incredibly great microfoam that you can even go hand-free Works really well with small milk quantity (12oz motta pitcher) too.

I am using this foam knife steam tip on a La Cimbali M29. Generally speaking, I have a great love for the original M29 steam capacity and tip and really have nothing but great experiences with them...in fact I'd classify my milk skills as well above average with the original gear

Ideal for small milk quantities steaming. Just missing five stars because of the price.

It's almost cheating. Encouraged by the foam knife, I am wondering how the vortex holds up.

This tip is working great on the GS/3. Very happy with the performance as advertised regarding quality and durability of micro-foam. Since the technique does not have to involve a stretching phase, the tip is especially useful for small amounts of milk where there is so little time to adjust and work. I'm sure there was a lot of RD to create this product, so I understand the price has to be up there to pay it off, but I still can't help feel that it's too much and I would join Todd in giving it two stars on price. But performance-wise it's up there.

I have a ECM single group machine and have difficulty to form good foam due the limited steam power. Many tips bought but neither of them have both speed and power. This is the only one that provide both the speed (velocity) and power for good micro foam. Recommend and worth every penny. SimonCHAN from Hong Kong

Similar performance to another after-market microfoam tip I have, but this one is a bit faster (and far more expe$ive). Performance: 4 stars. Price: 2 stars.
