9 reasons why people replace their old milk frother with a glass non-toxic frother

Grab your own frother tonight. Take out the whisk, hold the jug at an angle under the kitchen light. Dull spots, fine scratches, a bottom that’s lighter than the rim.

That’s not limescale. That’s the non-stick coating that was on it when it was new.

Researchers counted what is released after heating just once.

And in your jug, a whisk spins over that exact bottom twice a day.

In this jug, your milk touches glass and stainless steel. There’s no layer, so there’s also nothing that can wear off.

In the meantime, pay attention to what it says on other boxes. “PFOA-free” sounds reassuring, but PFOA is one substance from a group of more than ten thousand. What the inside is made of is almost never listed.

You don’t have to believe a label if you can see right through it.

With a coated frother, you’re scrubbing inside a jug with a brush. And that scrubbing is exactly what damages the coating you wanted to get rid of.

Milk residue doesn’t stick to glass. Run it under the tap, rinse twice, done. No sponge, no scraping off crust.

The jug also comes off the base, so it can go straight into the dishwasher. With most frothers, the electronics are in the jug—and then you can’t.

The most-mentioned compliment in our reviews isn’t about the foam. It’s about this.

And really, just in the dishwasher?

The glass jug, the lid, and the whisk are dishwasher-safe. Never submerge the motor base—it stays on the countertop.

So nothing ever really sticks?

Almost never—and we’re not going to pretend it’s zero. With hot chocolate and thick plant-based milk, a thin film can remain. The difference from before is that it comes off, because there’s no worn coating for it to cling to.

Weak foam with big bubbles isn’t because a device is too weak. It’s because it spins too fast in milk that’s too hot.

Foam gets firm when air is whipped into small bubbles, at a temperature where the milk protein can still support those bubbles. If the whisk goes too fast or the milk gets too hot, small bubbles collapse into big ones. It looks good for a moment, then sinks into your coffee within two minutes.

So the difference is in the settings: how fast the whisk spins, for how long, and at what temperature. Those three are fixed per program, put together with coffee lovers and baristas.

That’s why that foam cap stays put until the last sip.

Milk sticks as soon as the base goes above 70 degrees. A brown crust, every time. That’s why manufacturers put a non-stick coating in between. And it wears out.

This base stops at 65 degrees. Just below that line.

That’s also not coincidentally the temperature baristas stick to. That’s when milk is naturally at its sweetest. Above 70, it doesn’t get tastier—it gets flatter.

We didn’t cover up the problem. We removed it.

Warm thick foam for cappuccino. Warm thin foam for latte and flat white. Cold foam for iced coffee. Heat and stir for milk for tea.

And hot chocolate, with its own temperature of 75 degrees. That’s the button you’ll press most often this winter.

It starts by default on warm thick foam, so most mornings you just press start.

One button, five results. No second device for summer and no little pan for winter.

With most frothers, plant-based milk is where you notice the device can’t handle it. A thin layer of bubbles, and three seconds later it’s gone.

Not here. Oat, almond, soy, coconut, and whole milk all make a foam cap that stays put.

No special barista version needed. Just the carton that’s already in your fridge.

Most frothers are matte black plastic with a button on top. Fine, but you put them away after use because they don’t look good.

This one is 11.5 by 11.5 centimeters and 20.5 tall, with a clear glass jug on a sleek black base. In the reviews, people spontaneously call it a jewel in the kitchen.

That sounds like a minor detail. Until you realize you grab it twice a day.

Glass is still glass. Drop it on a tiled floor and it’ll break, and we’re not going to sugarcoat that.

But this isn’t goodbye. The separate glass jug costs 34.95 and a new whisk 19.95. The motor base just stays put.

With a coated frother, it works the other way around. Once the coating is worn out, the device is worn out. There’s no part that restores that coating, so the whole thing gets thrown away and you buy a new one.

Wear is depreciation there. Here, it’s simply a part.
