Special four hole steam tip
This included steam tip in the steam tip pack from Rocket is untraditional, because its a four hole steam tip with a center hole and three in the outer ring of the tip. I haven´t tried it yet, even though I have got one, simply because I can’t seem to found out how it can be logically good when frothing milk? More of that below the attached picture – but i theory it would be as aggressive as a normal four hole steam tip and therefore also non-preferable when having a small espresso machine like described before.
The three zones that will be created by this steam tip is equal to the three hole tip, but the center hole will beside these three areas, push the milk downwards and thereby create resistance in the three areas (In my mind). I will try it below and comment if this will be my new favorite steam tip or it will be kept hidden once more.
The result of the steam tip testing is listed in the above chart, where the frothing time is giving per. combination as well as the difficulty attached to it. The results were supportive of my previous assumptions regarding the increased speed of frothing when using more steaming holes – in other words the frothing is much faster when using a steam tip that allows more hot steam to merge with the milk. I found the standard four hole tip very useful when chasing the lowest amount of time spent on frothing – but the special four hole tip weren´t as quick as the standard, which impressed me a lot.With that said, speed isn’t everything, especially not when the primary focus is upon taste and quality – like mine is. I don’t really give a …. if it takes 20 sec. or 10 sec. as long as I get the best/optimal result. So which steam tip would I use myself? Hmm, well I honestly have been using the standard four hole tip for a week by now and I´ve got to know it better than the rest of the steam tips pack – but I’m actually most joyful upon the three hole tip, because it gave me the best velvety results.I blame it on the time, because I have been practicing with the four hole tip and therefore is used to its quickness of frothing, but with the three hole tip I got those extra seconds, where I could fine-tune my technique and create a bit more richer, smooth and velvety micro foam. This test where also performed with a 0,35 l. pitcher, which is kind of small when using a four hole tip, so I would properly use the four hole tip when frothing in a 0,6 l., 0,75 l. or 1,0 l. pitcher – nevertheless its always nice to have the option to change around a bit.* I would like to comment especially on the special four hole tip, because I was not very pleased with it during this test, because it sprayed milk out of the pitcher and also created some very big bobbles, when the whirlpools conflicted with each other. Therefore Im certain that I´ll never use this steam tip again and due to that it will be the worst steam tip choice of the pack.What does very easy, easy, medium and hard mean?
- Very Easy – the best possible condition when frothing milk, even a newborn coffee enthusiast will not experience any kind of trouble in the pursuit of great micro foam. The milk merging with the hot steam in the pitcher just flows with each other and you are left only to control the steam handle.
- Easy – its no big deal frothing milk and if you want to produce some excellent frothed milk in front of your friends, then nothing will stop you. This level doesn’t require much experience when frothing milk, just the basics about when to stretch the milk and stop heating it.
- Medium – The milk can be a challenge, but if you have patience and focus you´ll get the job done perfectly. This level requires some attention in the frothing action and is therefore not a simple job, if you want to be rewarded with the perfect micro foam.
- Hard – The hunt after the perfect micro foam is long gone and you have to struggle to get a decent result. This levels requires every aspect of your concentration and the possibility of failure is greater than success.
Choice of milk result
I can honestly say that between these five chosen milks lays a huge difference in taste and frothing ability – take for example the skimmed milk with 0,1% of fat, this milk separated when being frothed, leaving a very poor result when poured into the cup. This meaning that the skimmed milk at 0,1% is already out of the competition before is really started, because it was the only that separated, was thin tasting. The second skimmed milk with 0,5% fat were a bit easier to frothed and had some great quality such as great sweetness, thickness and excellent bobbles, but it were lacking when it came to support the coffee flavors and keeping a great depth in flavor.
The whole milk was honestly the most easy milk to get some great frothing results with, but the fat taste of cream affected the final cup a bit too much, to make it the best pick. Therefore was the five milks cut down to two, where they actually did great both. I couldn’t really tell them apart, so I would go for the low-fat milk, because it has better options for purchase than the special developed Barista milk.
A final note within the frothing area would be, that frothing the milk actually became more successful when giving the steam tips with more holes, because of the greater steam power and hereby action within the pitcher. The air simply became better incorporated in the milk comparing to the two holed tip for example.
I now this have been an extremely long article and I could have divided it in two or three parts, but I thought it would be interesting reading for you guys, so I wouldn’t have you all waiting for the other parts. Hope you enjoyed this review and thereby create your own opinions :)
The Rocket Evoluzione v2 also did magnificent doing these tests, because it just frothed all these milk test without even a single drop in steam capacity even once. Im truly glad for this wonderful machine, its just keep impressing me and increasing my passion for coffee, quality coffee.
