How To Steam Milk Using An Espresso Machine
How To Steam Milk: Steaming milk using an espresso machine might seem like a daunting task, but fear not – I’ve broken down the process into six simple steps. With a bit of practice, you’ll find yourself breezing through it in less than five minutes!
This recipe yields enough for an 8-ounce drink, but feel free to adjust the quantities to suit your preference. Assuming your espresso machine is all fired up and ready to go, let’s dive in.
Step 1: Measure The Milk
Pour 4 ounces (½ cup) of milk into a steaming pitcher. Most pitchers come with handy measurements etched on the side to make this step a breeze. Keep in mind that the milk will expand significantly as air is introduced during steaming.
Ensure your milk is cold for optimal results, as cold milk aerates more effectively. In warmer weather, you can even chill your steaming pitcher in the fridge beforehand.
Step 2: Position The Wand In The Pitcher
Comfort is key, even for aspiring home baristas. Position the steam wand towards one side of the pitcher, halfway down in the milk. This setup allows for easy maneuverability – simply move the jug up and down to switch between aeration and heating.
Make sure you can maintain this position comfortably to prevent wrist fatigue during steaming.
Step 3: Create The Foam
Activate the steam and lower the pitcher until the steam wand tip is just below the milk’s surface. This draws air into the milk, creating larger bubbles for a light foam.
The duration of this stage varies depending on your desired coffee drink. For a latte with a thin layer of foam, it may only take a few seconds, while a cappuccino might require up to 10 seconds for a 50/50 foam-to-milk ratio.
Step 4: Heat The Milk
Once you’ve achieved your desired foam, submerge the wand tip deeper into the milk to initiate the heating process. Ideally, the milk should form a gentle whirlpool motion around the wand.
This swirling motion ensures even heating and helps smooth out any larger bubbles, resulting in a uniform, silky texture.
Step 5: Know When To Stop
How To Steam Milk: The optimal temperature for steamed milk falls between 139 and 149°F, as recommended by the Specialty Coffee Association. While you’re still mastering the technique, a thermometer can help you hit the mark precisely. As you gain experience, you’ll be able to gauge the temperature by touch – the milk should feel hot but not scalding.
Once the milk reaches the desired temperature, turn off the steam and give the milk jug a gentle tap on the counter to eliminate any lingering large bubbles.
Pro Tip: Watch Your Temperature
Milk scalds around 170°F, resulting in a flavor you absolutely don’t want in your latte. If you hit this temperature, toss your milk and start over.
Step 6: Pour and Serve
How To Steam Milk: Using the milk right away is crucial; otherwise, it settles into two layers. If you’re not using it immediately, move the pitcher to swirl the milk around regularly to keep everything homogeneous.
For a great latte at home, pour the milk into the espresso in a circular motion to mix. If you have the skills, you can pour some decorative latte art. For a cappuccino, use a spoon to hold back the foam while you pour milk into the espresso. Then top with the foamed milk, using the spoon to scoop out any left in the pitcher.
Pro Tip: Cleanliness Is Key
Always clean the steam wand immediately after steaming your milk, even before enjoying your drink. First, purge it by releasing a quick burst of steam. Then wipe it down with a microfiber cloth. It’s 5 seconds very well spent.
How Do I Steam Milk Without A Steamer?
So you’ve just made espresso and need some frothed milk to top it off. But your coffee machine doesn’t have a steam wand. No problem. There are plenty of alternative ways to steam milk without an espresso machine.
Method #1: The Bellman Stovetop Steamer
The Bellman Stovetop Steamer is unique as the only way to truly steam (rather than froth) milk without an espresso machine. It’s a standalone steam wand attached to a little boiler that you heat on your stove, and you can steam milk using the exact steps above.
Method #2: Using A Jar
You can also froth milk using a jar although the result won’t be as good. Just follow the steps below:
1. Measure your milk into a glass jar with a tight-fitting lid, like a Mason jar or jam jar.
2. Shake vigorously until the milk is frothy.
3. Remove the lid and pop the jar in the microwave.
4. Cook in 30-second increments to heat the proteins in the milk and set your foam. Stop when you hit the 140°F sweet spot.
Method #3: With A French Press
How To Steam Milk: If you have a French Press at home, this is a better tool than a jar. Here’s how you can make ‘steamed milk’ with a French Press:
1. Heat milk using a microwave or stovetop to around 150°F, then measure it into a French press coffee maker.
2. Make sure the milk level is higher than the steel filter at its lowest point.
3. Pump the plunger up and down quickly to create air bubbles in the heated milk.
Method #4: Buy A Milk Frother
An automatic milk frother is the easiest way to froth milk at home, but they don’t come cheap. The best ones let you adjust the temperature and texture of the milk. A manual frother or frothing wand is a more budget-friendly option for aerating milk, but you’ll need to take care of the heating stage separately.
Method #5: Using A Saucepan And Whisk
Measure your milk into a small saucepan and place it on the stove over low-medium heat. As the milk warms, beat it rapidly with a balloon whisk until it is the temperature and foaminess you want.
What’s The Difference Between Steamed Milk And Frothed Milk?
The main difference between frothed and steamed milk is how it is made, which leads to other key differences. Steamed milk requires pressurized steam from a steam wand, which aerates and heats the milk. It is usually wetter than frothed milk. Frothing milk injects air into the milk any other way, and it can be hot or cold.
A skilled barista can make any milk texture using a steam wand, from an airy froth to a creamy microfoam. Most frothers are best for making lighter foams, though the expensive models might give you a creamier option.
What’s The Best Milk For Steamed Milk?
How To Steam Milk: Coffee experts generally agree that the best milk for frothing is whole milk or 2% milk. Let’s quickly look at why without diving too deep into the science.
Milk comprises sugar, fats, and proteins, and it is the ratio of these components that dictates the flavor and texture of your milk froth.
Milk with a higher protein-to-fat ratio, like skim milk or 1% milk, produces a stiffer, lighter foam. Milk with a higher fat content, like half-and-half for a breve, yields a very dense and creamy foam. Whole milk and 2% milk occupy a happy middle ground – a fluffy foam, rich mouthfeel, and gentle sweetness.
No matter which milk you choose, always use fresh, cold milk – the freshest you can find. As milk ages, the ability to make foam deteriorates. As with coffee beans, buy only as much as you’re likely to use in a week.
Non-Dairy Milk Alternatives
Plant-based milks are growing in popularity, so it is increasingly possible to make perfect microfoam without dairy milk. Look for a non-dairy milk labeled “Barista Style” for best results. These are specially formulated to mimic the protein-to-fat ratio of whole or 2% milk. Plan on adjusting your timing to accommodate the different properties of plant-based milk.
My favorite non-dairy milk for coffee is oat milk because it has a neutral flavor and natural sweetness similar to dairy milk. Almond milk is another good choice. Coconut milk and soy milk froth well but significantly alter the flavor of your drink – a pro or a con, depending on your taste.
Final Thoughts
How To Steam Milk: Steaming milk at home isn’t nearly as intimidating as you’ve been led to believe. With this guide, you can create steamed milk for creamy lattes and foamy cappuccinos. Just remember the two key stages – aeration and heating – and that there’s no substitute for practice, practice, practice.
