Milk Frothers: How to Choose the Best Frother for Lattes, Cappuccinos & Cold Foam
What Is a Milk Frother?
A milk frother aerates milk to create foam for lattes, cappuccinos, macchiatos, cold coffee, matcha and hot chocolate. Handheld frothers provide inexpensive manual frothing, while automatic electric milk frothers can heat milk and produce hot or cold foam at the touch of a button. More advanced models can create fine microfoam for latte-style drinks and work with dairy and plant-based milks.
Find the Right Milk Frother
The best milk frother isn’t necessarily the most expensive one. The better question is what kind of drinks do you want to make?
If you simply want extra foam on morning coffee, a $15–$20 handheld wand may be enough. If you regularly make cappuccinos or lattes, an automatic electric frother that heats and froths milk removes several steps. And if your goal is fine microfoam for flat whites or latte art, look for a machine specifically engineered for finer foam texture.
Quick Milk Frother Buying Guide
| Type | Best For | Heats Milk? | Main Advantage | Typical Tradeoff |
|---|---|---|---|---|
| Handheld wand | Occasional coffee, travel | No | Cheap and compact | Requires manual frothing |
| Automatic jug | Lattes and cappuccinos | Usually | One-touch convenience | Higher price |
| Multi-function frother | Several drink styles | Yes | Multiple foam textures | More controls/cleaning |
| Microfoam frother | Flat whites, latte art | Yes | Finer foam | Usually costs more |
The distinction matters. A milk frother and steamer can replace the separate heating step required by a handheld wand, while specialized microfoam machines provide substantially more control over texture.

Featured Milk Frothers to Compare
These products illustrate the three main buying levels: inexpensive handheld, affordable automatic and more advanced automatic frothing.
1. Zulay Milk Boss — Simple Handheld Frothing
The Zulay Milk Boss represents the simplest route into milk frothing.
Instead of heating milk, its powered whisk rapidly incorporates air into milk you’ve already heated—or cold milk for iced drinks. Zulay describes it as suitable for lattes, cappuccinos and matcha, and the current battery-included Milk Boss is designed with a detachable whisk for easier rinsing.
Its advantages are price, portability and storage. A handheld wand occupies very little space and can also mix matcha, powdered beverages and other drinks.
The compromise is that you control the process. There is no automatic temperature setting and no integrated milk heater.

2. Instant Pot 4-in-1 — Everyday Automatic Frothing
For shoppers who want the machine to handle more of the work, the Instant Pot 4-in-1 Milk Frother moves into automatic territory.
Instant provides four functions:
- Cold foam
- Light warm foam
- Dense warm foam
- Milk warming
Instant specifies a 17-ounce capacity and says the machine creates microfoam from both dairy and non-dairy beverages.
This combination makes the Instant especially relevant to someone who wants one appliance for morning lattes, cappuccinos, cold coffee and warm milk without paying for dozens of settings.

3. Dreo BaristaMaker Air — More Foam Options
The Dreo BaristaMaker Air is a step up for shoppers who want more control over drink preparation.
Dreo lists eight settings, a 9-ounce capacity and compatibility with dairy and non-dairy milk. The company recommends beginning with cold milk at roughly 45–60°F and using barista-grade plant milk when possible.
The Air is also compact at 3.8 inches wide and 8 inches high. Dreo specifies a maximum 4 ounces for thick foam and a 10-ounce MAX STIR marking, so it is particularly appropriate for one-drink-at-a-time preparation.

4. Dreo BaristaMaker — For Microfoam & More Control
Move beyond the Air and the full-size Dreo BaristaMaker becomes a substantially different appliance.
Dreo specifies 30+ foam options, three microfoam styles—flat white, latte and cappuccino—hot and cold thick foam, adjustable temperatures from 130°F to 170°F, automatic shut-off and a 600W US-version power rating.
Its vessel holds 27.1 ounces, although actual maximum frothing capacity is 8.5 ounces and maximum stirring capacity is 15.2 ounces.
This is the category of machine to investigate when foam texture itself becomes part of the hobby rather than merely wanting some foam on top of coffee.

Electric vs. Handheld Milk Frothers
This is the first decision most shoppers should make.
Choose a handheld milk frother when:
You already have a convenient way to heat milk, don’t want another countertop appliance, need something inexpensive, or want a frother that can easily fit into a drawer or travel bag.
A wand also gives you direct control. Move it through the milk until you reach the amount of aeration you want.
Choose an automatic electric frother when:
You make lattes or cappuccinos regularly and value repeatability and convenience.
Instead of heating the milk separately and manually whisking it, an automatic machine can perform the heating and frothing cycle for you. Models such as the Instant Pot also let you choose between cold, light warm and dense warm foam.
What Is Microfoam?
Not all foam is the same.
Traditional frothy cappuccino milk can have a relatively airy structure. Microfoam consists of much finer bubbles integrated into the milk, producing a smoother, glossier texture.
That difference becomes particularly important for flat whites and latte art.
Dreo, for example, markets its full-size BaristaMaker around microfoam and provides dedicated flat-white, latte and cappuccino foam settings.
If your objective is simply a thick foamy cappuccino, you may not need to pay extra for that degree of control.
Can You Froth Oat, Almond and Soy Milk?
Yes—but results vary.
Plant-based milks differ significantly in protein, fat, stabilizers and other ingredients. Consequently, two cartons labeled “oat milk” can behave differently when aerated.
Dreo recommends barista-grade plant-based milk for its BaristaMaker Air and advises starting with cold milk.
Instant likewise says its Milk Frother is designed to create microfoam from both dairy and non-dairy beverages.
If plant-based coffee is your everyday routine, this deserves its own buying decision rather than assuming a machine that performs well with whole milk will produce identical results with every milk alternative.
Hot Foam vs. Cold Foam
Hot foam is the traditional choice for cappuccinos, lattes and macchiatos. The appliance heats the milk while introducing air.
Cold foam is designed for iced coffee, cold brew and other chilled drinks. It adds texture without heating the beverage.
If you regularly alternate between hot and iced coffee, look specifically for a machine offering both hot and cold frothing modes rather than assuming every electric frother does.
The Instant 4-in-1 provides both, while Dreo’s BaristaMaker line also supports hot and cold foam preparation.
What to Look for Before Buying a Milk Frother
The number of modes printed on the box shouldn’t be the only deciding factor. Focus on these practical differences:
Capacity matters. Frothing capacity can be much lower than the vessel’s total capacity because milk expands as air is incorporated. Compare the manufacturer’s frothing fill line rather than simply comparing pitcher sizes.
Cleaning matters. Milk residue can dry quickly. Removable whisks, accessible interiors and dishwasher-safe components can make a major difference if you use the machine daily.
Think about your milk. If you primarily use oat, almond, soy or coconut milk, investigate the manufacturer’s plant-milk recommendations.
Check automatic shut-off. This is a useful feature for an appliance combining heat and electricity. Dreo’s full-size BaristaMaker, for example, specifies automatic shut-off and dual temperature sensors.
Don’t pay for settings you won’t use. Someone who makes one cappuccino every morning may get more value from a straightforward four-function machine than from dozens of foam combinations.

Milk Frother FAQ
What does a milk frother do?
A milk frother incorporates air into milk to create a lighter, foamy texture. Depending on the machine, it may also heat the milk and offer different hot, cold, dense or microfoam settings.
Is an electric milk frother worth buying?
It can be worthwhile for people who regularly make lattes, cappuccinos or other milk-based drinks. Electric models automate more of the heating and frothing process than handheld wands.
Can a milk frother heat milk?
Some can. Automatic models such as the Instant Pot Milk Frother include a dedicated milk-warming function. Handheld frothing wands generally do not heat milk.
Can you make cold foam with a milk frother?
Yes, provided the machine includes a cold-frothing mode. Instant lists cold foam among its four functions, and Dreo’s BaristaMaker series includes hot and cold foam options.
Can you use a milk frother for hot chocolate?
Many automatic machines can warm or stir milk for hot chocolate, although capabilities vary by model. Check the manufacturer’s instructions before adding powders or ingredients directly to a frothing jug.
What’s the difference between a milk frother and a milk steamer?
A frother primarily incorporates air to create foam. Traditional steam wands heat milk with steam while simultaneously allowing a barista to introduce air and texture the milk. Many countertop appliances marketed as “frothers and steamers” use electric heating rather than a true espresso-machine steam wand.
