A Guide on How to Steam Milk

If you know the how to steam milk the correct way, you'll find it is a delicious way to add flavor and sweetness to coffee, but without using any type of added sugars or sweeteners.

The steam and heat causes chemical changes to take place within the milk, and increases its volume, which is how the practice also got the name stretching in addition to steaming.

What You'll Need

• Cold milk
• Frothing thermometer
• Steaming Pitcher (cold)
• Steam wand

How to Steam Milk Steps

Begin with a cold, stainless steel pitcher and milk that's also as cold as possible, but neither should be near the freezing mark. Putting the pitcher in the freezer for about 10 minutes should get it to the right temperature.

The type of milk you use is mostly a matter of personal preference, although different kinds of milk do create different types of foam. For example:

Whole Milk
Whole milk undoubtedly offers the fullest, richest of flavors, although it is the hardest to work with in terms of achieving the right amount and size foam. In places where milk steaming is regarded as a work of art, such as France or Italy, whole milk is used most often.

2% Milk
Two percent milk provides the right balance for the best results when steaming or foaming, and it also offers a rather tasty, creamy flavor.

Non-Fat Milk
While non-fat or skim milk will be the easiest to foam for those just learning how to master the practice, it doesn't provide the richest of tastes.

The next step is to pour your choice of milk into a cold pitcher until it's about half full, allowing room for the foam. Using this particular method, attach the frothing thermometer to the pitcher until it reaches the desired temperature. Depending on personal preference, this could be anywhere from 145° to 165° Fahrenheit. The best thermometers clip on to the side of the pitcher for easier use.

Placing the pitcher under the steam wand, and ensuring the wand reaches to the bottom, turn the power on while starting to slowly move the pitcher. As the milk rises, the steaming pitcher will need to be slightly lowered. Ideally, the tip of the wand should then be a quarter to a half inch beneath the surface. It should remain there until the right amount of stiff foam appears. Take care not to completely pull the steam wand from the pitcher as it may cause the milk to spray out.

Learning How to Steam Milk Using the Correct Temperatures

The exact temperature for milk steaming will depend on how the coffee is actually being served and the type of cup used. It's also dependent on if the coffee will be drank right away. Which is when all types of coffee drinks taste the best, just after they've been freshly prepared.

Anything higher than 160° Fahrenheit may cause the milk to taste scalded, although some people do prefer temperatures up to 170° Fahrenheit. The 160 degree threshold is generally the ideal temperature of drinks that are being served "to-go" in the usual cups, or of those with whipped cream added to the top. As for how to steam milk at home with the right temperature, aim between 150° and 155° Fahrenheit for drinks poured into cups that have already been heated.

One trick to remember for the best results is, turn off the steam wand when the temperature reaches within five to 10 degrees from the desired mark. If you wait until the needle settled on 155° Fahrenheit, you would see the exact and final temperature may actually be too hot, scalding the milk and ruining the taste of the entire drink.

Important Tips to Remember on How to Steam Milk

Milk that is steamed to savory perfection will appear nearly completely smooth on the surface, but with tiniest hints of tight, bubbly foam. The air is what gives the milk its sweetness and full flavor, and without it, drinks would be dull and boring with a flat taste.

For the beginner, the inevitable larger bubbles will more than likely appear on a few occasions. Take it to heart that this happens to everyone and simply try again. Practice really does make perfect when it comes to learning how to steam milk.

Try tapping the container on a hard surface a few times to see if the bigger bubbles will settle and disperse, if so, you'll want to give the milk an extra boost by spinning the pitcher or container around in tight circles. Don't tap too hard, and if you've done it just right, it will now appear smooth with a lustrous sheen instead of the bubbly, dull appearance before spinning. The volume of the milk will also have increased by as much as 50%.

It's also important to try to gauge how much milk you will need, and only use that amount. Until you are able to tell just by looking, as the more experienced barista will often do, pour the milk into the cups you're using until they're about 75% full. Leave room for the foam and any extras to pre-measure.

While this isn't always necessarily precise, it's better than guessing when you are just starting to learn how to steam milk, practicing and experimenting with the various methods used.

The more milk you use for steaming, the more foam that will be created. However, if you end up using too little milk, you run the risk of it heating up too quickly. This doesn't allow the full flavor to develop.

Much like anything we do in life, it requires practice, patience, and attention to detail when you're learning how to steam milk for the best results.
