Quick Overview

Product description

"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 was coined 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.

This tip is fabricated with a female 1/8" British Standard size and thread, which is unlike most metric threads used by the most common espresso machine parts manufactures. The Sproline Foam Knife 1 Steam Tip will fit Commercial La Marzocco and Slayer Espresso machines. It will also fit directly onto the stock Nuova Simonelli 'Oscar' model steam wand. It will not fit equipment that uses an M10 metric size and thread, such as is found on many commercial and pro-sumer manufactures steam wands.

Made in Japan.

Works great with Rocket Giotto (with adapter) Review by WL
Item Rating

I was advised that it won't fit but using an adapter from the hot water arm of my Giotto Premium Plus V2, it works perfectly. Creates the best microfoam out of all steam tips I've tried.

Wallet lightener, nothing more Review by uscfroadie
Item Rating

What a waste of $115. This tip is no better than the standard tip that came on my GS/3. Beautifully made, but for $115, it had better be. The performance is not better than what I got as standard equipment. Definitely a try before you buy item.

Not compatible Review by Lulu
Item Rating

I bought the sproline foam knife steam tip to use with my Victoria Arduino Adonis which has a stainless steam wand just like the one that comes with other simonelli models such as aurelia appia etc. However the tip is not compatible with my steam wand and I knew that. I sent an email to Espresso Parts inquiring about the adapter with no response. After researching online I ordered a GB-5/FB-80 steam wand because the foam knife is compatible with it. But I'm still interested if anyone knows where I can find an adapter to make it fit my original steam wand. Thanks.

Excellent Tip Review by Jerred
Item Rating

I replaced my Vesuvius steam wand/tip with a GB-5 Wand and the Sproline Foam Knife. It used to be quite difficult to get any microfoam on my cappuccinos prior to using this tip. There is a bit of a learning curve but first try out of the gate I was able to get a MUCH better drink.

It' s incredible Review by Gilberto

Ineffective for Me Review by CO_Espresso_Pro

I've now made a few hundred 6oz cappuccinos with this tip. For my application it's substantially inferior to the standard tip that comes with the GS3. This might be because I'm steaming very little milkā€”it may work better for larger drinks. Or on a different machine. It's coming off this weekend.

Expensive Tip Review by Danny

This is an expensive tip that has produced minimal results for me so far. For the price it should come with a tutorial video.
