# FAQ — Milk Frothers & Steaming

**What's the difference between frothing and steaming milk?**
Steaming heats milk while incorporating air to create microfoam—that velvety texture you want for lattes and cappuccinos. Frothing is just adding air without much heat, giving you bigger, wetter bubbles. For espresso drinks at home, you really want steaming. If you're just topping coffee with foam, a basic frother works fine.

**Can I use cold milk straight from the fridge with a steam wand?**
Yes, and actually you should. Cold milk froths better because the temperature difference helps you control when the foam breaks down. Start with the tip just barely submerged to draw in air (you'll hear a chirping sound), then lower the wand once you've got good volume. Aim to get milk to around 150–155°F before you stop steaming.

**How do I avoid scorching milk when steaming?**
The biggest thing is positioning—keep your steam wand tip near the surface of the milk and angle the pitcher so the milk swirls. If you bury the tip too deep, you'll generate too much heat in one spot. Also, don't steam past 155–160°F; once milk gets hotter than that, it starts tasting scalded and breaks down the proteins that create good foam.

**Are electric milk frothers good enough for espresso drinks?**
Electric frothers are convenient for quick hot foam, but they won't give you the velvety microfoam texture that works well with espresso. They tend to make bigger bubbles and less integrated foam. If you're serious about lattes and cappuccinos, a steam wand on an espresso machine or a handheld steam frother will give you better results.

**Which handheld milk frother should I buy if I don't have an espresso machine?**
I've had good results with battery-powered aeroccino-style frothers—they're fast and consistent. The key is milk quality and temperature control, not the frother itself. Look for one with a whisk (not a paddle) for better microfoam, and make sure it has a descent lid so you're not wearing hot milk. Most decent ones run $30–60.

**Why does my homemade milk foam separate into liquid and bubbles?**
That usually means your foam broke down because the milk got too hot or sat too long before you poured it. If you're using a handheld frother, try using it right before you pour—don't let the foam sit in the cup. If you're steaming, watch your temperature and avoid reheating milk that's already been frothed once.

**What type of milk froths best?**
Whole milk froths easiest because the fat helps stabilize bubbles and adds sweetness. Skim milk works but creates bigger, wetter bubbles that don't integrate as smoothly. Oat and soy milk can work well too—oat milk especially has gotten better for steaming over the last few years. Avoid ultra-high-temperature (UHT) milk if you can; it won't froth as well.

**Do I need to purge my steam wand before and after frothing?**
Yes—purge for a second before steaming to clear condensation, and definitely purge right after while there's still pressure. Milk proteins will dry and cake on your wand otherwise, and that's annoying to clean. Wipe the tip with a damp cloth immediately after each use, and backflush (if your machine allows it) once a day.

**How do I clean milk out of a steam wand properly?**
Wipe the outside tip immediately after steaming while milk is still wet. If it dries, soak the wand in hot water for a few minutes to soften it first. Use a damp cloth or soft brush to gently scrub around the holes—don't jam anything into them. Once a week, backflush (run steam without milk) to clear the inside, or soak a removable wand in hot water with a bit of espresso machine cleaner if buildup happens.

**Can I steam milk in a regular pitcher, or do I need a special milk pitcher?**
A proper milk pitcher (usually stainless steel, 12–20 oz) makes steaming way easier because of the shape and spout control. Regular kitchen pitchers work in a pinch, but they're usually too wide or deep, making it hard to position the wand correctly and pour latte art. The angle of a barista pitcher also lets you create that crucial swirl in the milk during steaming.
