Buy the Breville Milk Cafe if you froth for more than one person. It holds 740ml (25 fl oz), enough for about 3 cups, on a 500 watt induction base, and lists at $199.95. The Nespresso Aeroccino 4 is the countertop pick for one or two drinks: 120ml (4 oz) of foam or 240ml (8 oz) of hot milk, a smaller footprint, and a lower price. Same job, two different scales. Pick by how many cups you pour, not by which brand you already own.
Capacity is the whole decision
Everything else follows from the jug size. The Breville Milk Cafe BMF600 runs a 740ml stainless jug that sits on an induction heating base, which heats the jug directly instead of through a hotplate, so the milk warms evenly and the jug itself is dishwasher safe. That capacity is the point: three cappuccinos in one go, or a big batch of hot chocolate. It comes with two frothing discs, one for latte texture and one for the thicker cappuccino foam, and a set of temperature settings covering Cold Stir, Warm, Optimum Temperature, and Hot. There is a measuring cap for adding cocoa or powder mid-mix. It is a stainless machine roughly 6.4 by 7.5 by 10.4 inches, so it takes real counter space.
The Aeroccino 4 is built for the single-serve rhythm most Nespresso owners already have. Its jug tops out at 120ml of foam or 240ml of hot milk, which is one latte or two small drinks before a refill. What it lacks in volume it makes up in options: four froth styles, two types of hot foam plus hot milk and cold foam, selected with capacitive touch buttons. It is small, about 4.3 by 4.3 by 7.4 inches, dishwasher safe, and drops to under half a watt in standby. If you already pull a shot from a Vertuo or Original machine, this is the frother the system was designed around.

One thing the table flattens: texture. The Breville's two discs let you push toward wetter latte foam or stiffer cappuccino foam on purpose, which matters if you care about pour consistency across a batch. The Aeroccino gives you preset styles rather than swappable discs, so you choose from what Nespresso tuned rather than dialing it yourself. Neither makes true steam-wand microfoam. Both make good enough foam for a home latte, and both fall short of what a proper steam wand does on an espresso machine.

Which one fits your kitchen
Go Breville if you make drinks for a household, want hot chocolate in the same machine, or care about controlling foam texture with the two discs. The 740ml jug is the reason to spend more, and induction heating is the reason the milk warms cleanly. Go Aeroccino 4 if you are a one or two cup person, already run a Nespresso machine, and want something small that lives on the counter without dominating it. The four presets cover most home drinks, and the smaller price and footprint are the trade for the smaller jug. If you are still deciding whether a standalone frother is even the move, our guide to coffee machines with an automatic milk frother covers the all-in-one route instead.

FAQ
Which holds more milk, the Breville Milk Cafe or the Aeroccino 4? The Breville, by a wide margin. Its jug holds up to 740ml, about 3 cups, while the Aeroccino 4 tops out at 120ml of foam or 240ml of hot milk, which is one or two drinks per batch.
Does either make hot chocolate? The Breville Milk Cafe is set up for it, with a measuring cap for adding cocoa or powder once mixing starts. The Aeroccino 4 does not list hot chocolate as a function, though warm milk plus your own mix still works.
Do I need a Nespresso machine to use the Aeroccino 4? No. The Aeroccino 4 is a standalone milk frother that works on its own with any coffee, but it is designed to pair with Nespresso Original and Vertuo machines, which is why it suits owners of that system.
