New Andreja owner with microfoam problem - Page 6

Good point about the thermometer, it will take that back. But do try dropping the pitcher to just below the tip, this seems to get a nice foam with the small bubbles that your are looking for, ie riding the foam up. If you drop it too close to the end, then the evil soap bubbles will surface.

the only thing i see wrong is that youre not sinking the tip in toward the end, this should help spread the stretched milk everywhere. it looks perfect, its just not distributed throughout the pitcher

I'm still struggling with my Vetrano as well, so I'm no expert. But when I look for differences between your video and Cannonfodder's, I see a difference in the angle of the steam wand. Cannonfodder seems to have the wand at more of an angle, while yours appears to be pointing almost straight down. Does this make any difference?

I'm also still a bit confused about the movement I'm supposed to be creating in the pitcher. Should I be creating a whirlpool effect like I would see in a draining sink, or should it be a vertical whirlpool swirling from top to bottom?

Cheers,

Andrew

HBL has an Andreja with a lower volume tip than your Vetrano, so the optimal techniques aren't the same. Looking at the video, I would have stretched for longer and introduced slightly more air during the stretching phase, assuming the goal was to produce a cappuccino (as opposed to the wisp of foam of a latte). There wasn't enough foam for a proper pour, but still it was apparent that the microfoam had already separated or was never successfully integrated. The low-volume tips don't rock-n-roll the milk aggressively, so you need to thunk-n-swirl more at the end to assure a homogeneous mixture (I also like a little side-to-side swish motion for combining microfoam).

I'm also still a bit confused about the movement I'm supposed to be creating in the pitcher. Should I be creating a whirlpool effect like I would see in a draining sink, or should it be a vertical whirlpool swirling from top to bottom?

For most espresso machines, including the Vetrano, I prefer this direction:

I angle the wand more for the low-volume tips since they don't push the milk around easily. Otherwise the whirlpooling is more like a draining sink. Practice creating the desired motion with water (be careful to watch the water temperature to avoid scalding yourself!).

Different machines require different techniques. My Gaggia Factory lever (the photo above), my Isomac and my Faema all use different techniques.

You video looks close, very very close. I would offer to stop by if I were traveling in your area but your location is not set in your profile. I will be in Newark, Philadelphia and New York City the last week of the month.

Keep in mind that you can also steam too quickly. That is not normally a problem with a home machine but the commercial machines with 2bar steam boilers will actually heat milk too fast. I was discussing it with Jim a couple of days ago. The accepted minimum to develop the sweetness in the milk is 15 seconds.

I agree with the whirlpooling. As far as I know for latte's you don't need a lot of foam. Stretching 'till about 70F is enough. After that it's whirling the foam throughout the rest of the volume of milk. The better the rolling vortex and whirlpool the tighter I find the foam gets. I don't let it sit at all after frothing either. Knock it to get out the larger bubbles, give it a good spin and pour right away. The best vortex comes with with the wand at a good angle, just off to the right and pointing to where a good clockwise roll starts happening.
