new stainless steel synesso steam tips 6-hole

We unboxed our new 1mm orifice 6 hole stainless steel steam tip this morning and installed. It is almost the same as the 4 hole 1.5mm tips. Technically the speed should be the same, but the affect is better due to a greater distribution i.e. smoother.

Synesso standard was 1.8mm 4-hole tips, however we set our clients up and have always recommended the 1.5mm orifices as that had the best effect for us. cumulative 1.5×4= 6 output. Our new SS tips are 1×6= 6 output. The reason for the switch is that stainless steel will be much easier to clean. It takes a lot of money to caste your own forms out of stainless steel, so the normal route is to make it brass and then chrome plate. Our previous tips were all chrome plated brass, and sure the chrome flaked off, and chrome is not the best clean surface, but way better than brass or copper.

[apparently] six holes at 1mm, and 4 holes at 1.5mm do not equal the same thing because.. is it pie r squared? I am not a math person, but im going to look this up and update this post.

On bar the question was asked- whats the difference. Technically smaller holes put out higher pressure with lower volume over time. Larger holes are lower pressure with higher volume. The pressure in the steam tank is a constant, or lets say it is for the sake of discussion. if you put your finger over a hose nozzle the water will spray out much faster, but the amount of water decreases. steaming milk type products requires a certain amount of turbulence to mix air into the liquid and add texture (kind of like making amazing foam in a bubble bath). we can try to foam something up, but the deeper question is what allows us to create tight foam. Fats and sugars are the answer, as well as increasing those through developing them with heat, which is what we do when steaming milk. and the crazy thing is we think about this everytime we make your latte.
