Milk and Art

Background

It's hard to pin down when exactly latte art was invented, or who invented it. Coffee geek lore has it that Espresso Vivace's David Schomer was the first American to really nail it back in the mid-eighties. In Italy, meanwhile, a gentleman named Luigi Lupi was doing the same thing around the same time. 

One thing's for sure, though: Developing perfect latte art is a bit like beginning an exercise regimen. Things may start out a little awkward and puffy, but you're guaranteed steady (if modest) progress if you hang in there. Though there is disagreement within the coffee world about what milk's proper texture ought to be, we (along with pretty much all the other specialty coffee companies) prefer to craft a silky "microfoam" – something akin to wet paint or "white chrome," as Schomer himself put it all those years ago.

What you'll need

Milk_pour Nozzle
If you have a 12-oz. pitcher, fill it with about 10 oz. of milk; 14 oz. will do in a 20-oz. pitcher. 
In either case, this is about a pinky's width below the bottom of the nozzle.

Angle the pitcher and so that your steamwand is aimed diagonally into the milk's lower right quadrant.

Place the tip of the wand a centimeter or two below the milk's surface and turn it on. You'll hear a tearing sound. Don't let it frighten you. After about two seconds, quickly but purposefully submerge the wand below the surface of the milk – not so deep that you hit the side of the pitcher, not so shallow that you continue to create bubbles.

Submerging the wand will create the "whirlpool" motion necessary to break down bubbles and create microfoam.

Once your milk has reached the appropriate temperature (between 140-145 degrees Fahrenheit), turn off the steam wand. Purge it, and give it a few vigorous wipes with a clean towel.

Milk_tap Swirl

Tap the pitcher on a flat surface to break any remaining bubbles. Give it a few swirls to equalize the texture. The consistency should resemble wet paint, or “white chrome,” to borrow a phrase from Espresso Vivace's David Schomer.

To achieve exquisite latte art, begin pouring your milk slowly. Start with a narrow stream to avoid breaking the espresso's crema. Once your drink is about half full, lower your pitcher's spout so that it's almost touching the liquid. This will guarantee strong contrast. Continue pouring.

Pouring a Heart

Pour2 Crush

To form a heart, create a white dot with your milk. Once the drink is almost full, raise your pitcher up a few inches from the drink (while still maintaining your gentle pour), and "cut" it down the middle. Serve to your crush, and smile coquettishly.

Pouring a Rosetta

Lastone Rosetta2

To form a rosetta, create the same white dot by starting your pour close to the espresso’s surface. As you pull away, gently rotate your wrist from side to side.  Don’t forget to breathe. You carry all your stress in your rosetta leaves.

Continue moving wrist side-to-side while keeping pitcher’s spout close to the surface of the drink.

Lift your pitcher a few inches and reduce the speed of your pour. The height, along with the thin stream, will allow you to cleanly cut the rosetta down the middle.

Serve, then exhale and wipe your sweat-drenched brow. To guarantee excellent art, consider practicing this routine 500 times each day for three years.
