Pouring good latte art is half good steamed milk and half pouring technique. This guide focuses on the steaming.
Good coffee need not be a luxury! My Gaggia was fairly inexpensive, but it's not the best—especially at steaming. Know your machine (and its limitations) and you'll do well with it.
I use a 12-ounce pitcher and a thermometer, both from Rattleware. You can use a larger size if you want, but I think this is an easier size to control—and the perfect amount for a latte!
This is the right amount of milk for my cups, approximately 3 fluid ounces of milk. I know it's to the bottom of the thermometer clasp. You can also measure it. Don't want to come up short!
Leaving the wand in I turn down the steam at this point or the Gaggia peters out before the end. (Like I said, not the best!) Just long enough to rebuild pressure; the light comes back on when ready.
Go forth and pour! ☕
