Q. Which is better: A 2-hole or 4 hole steam wand tip?
A. We tested these two tips on the Rocket Giotto Evoluzione, which comes standard with a 2-hole tip but has a 4-hole tip upgrade option.
We found that the 2-hole tip gives you a little more control, but requires that you work the milk a bit more to produce a nice microfoam. The 4-hole tip required less 'stretching', and heated the milk faster, but it has a lot more power so you need to use at least a 20 oz. pitcher. It definitely rolls the milk smoothly.
But keep in mind that this applies only to machines with larger boilers; if you have a machine with a small single boiler, a 1-hole steam tip is your best bet. If your boiler isn't big enough, you won't have enough steam power to achieve good results. For example, the Rancilio Silvia V3 performs better with a 1-hole tip than the 3-hole tip that was originally included on the first iteration of the machines.
