The best milk frother for oat milk
Why oat milk foams differently, why barista editions matter, and four UK frothers with the controls that help, from Melitta, Lakeland, Dualit and Smeg, with prices checked 3 Oct 2026.
The best milk frother for oat milk is less about the machine than you might expect: the milk itself makes the biggest difference. Barista oat drinks are made to heat and foam without splitting, while standard oat milk often gives thin, short-lived foam in any frother. That said, a frother with gentle heat and a choice of light or dense foam gives you more control. This guide explains why oat milk behaves differently, what to look for and four frothers sold in the UK, with prices checked 3 Oct 2026. We haven’t tested this in person. Picks are based on maker and retailer specs and current prices. Read how we compare.
Why oat milk foams differently
Dairy milk foams well thanks to its proteins and fat. Oat milk has much less protein, so standard cartons often foam weakly or collapse quickly.
- Barista editions add oil and stabilisers such as potassium phosphates so the drink holds a foam and resists splitting in hot coffee.
- Temperature matters. Sage UK’s latte recipe suggests keeping non-dairy milk to about 55°C because it can separate if it gets hotter. Alpro’s barista oat pack says steam to a maximum of 65°C, and Sainsbury’s own barista oat says up to 70°C.
- Brand matters. Sage’s Milk Café user guide notes that some milk brands produce more froth than others, and that some soy milks froth while others don’t. The same applies to oat drinks.
Our guide to the best oat milk for coffee compares barista editions and their heating advice.
Who it isn’t for: anyone using dairy milk. Almost any frother will foam it well.
Best milk frother for oat milk: what to look for
None of the frother listings we checked on 3 Oct 2026 had an oat-specific setting. So look for:
- Light and dense foam options, so you can go lighter if oat foam turns stiff or bubbly.
- A cold froth setting, because chilled oat milk can make good cold foam.
- Moderate heat. A frother that heats to the top of its range may push oat milk past the temperature its maker suggests.
- A non-stick or dishwasher-safe jug, because oat drinks can leave a film.
Who it isn’t for: people happy with a handheld wand. See our best handheld milk frother guide for those.
Budget pick: Lakeland Milk and Hot Chocolate Frother
The Lakeland Milk and Hot Chocolate Frother is £44.99 at Lakeland, checked 3 Oct 2026. Lakeland lists four settings and says milk is heated to 60 to 80°C, with a non-stick interior. Note that the top of that range is above what Sage and Alpro suggest for plant milk.
Who it isn’t for: anyone who wants a frother listed for plant milk. Lakeland’s listing doesn’t mention it.
Best for named plant milks: Melitta Cremio II
The black Melitta Cremio II is £46.99 at Currys, checked 3 Oct 2026. It’s the only frother we checked whose listing names a plant milk: Currys says you can choose “any milk from lactose-free, soya or full cream”. Currys lists a 250ml capacity and mentions hot chocolate and iced coffee.
Who it isn’t for: anyone who wants oat named outright. Soya is mentioned, but oat isn’t.
Best for larger batches: Dualit Milk Frother Max
The Dualit 84150 Milk Frother Max is £98.99 at Currys, checked 3 Oct 2026, prices can change. Currys lists a 580ml capacity, and Dualit describes its VortecS whisking system.
Who it isn’t for: single-cup households. A 580ml jug is more than one latte needs.
Most control: Smeg MFF11
The black Smeg MFF11BLUK is £149.97 at Currys, checked 3 Oct 2026, prices can change. Smeg UK lists six pre-set programmes covering hot and cold milk with light or dense foam, plus manual hot and cold modes, induction heating and a dishwasher-safe carafe.
That range of light, dense and cold options gives the most room to adjust for oat milk. There’s more in our Smeg milk frother MFF11 review.
Who it isn’t for: anyone on a budget, or anyone wanting to set an exact temperature. Smeg lists programmes, not a temperature dial.
Tips for frothing oat milk
- Use a barista edition and shake the carton well.
- Start cold, straight from the fridge if your milk’s instructions allow.
- Try the light foam setting first, then dense if it’s too thin.
- Don’t re-heat. Alpro’s pack advises against re-steaming.
- Clean the jug straight away.
For cold drinks, see our milk frother for cold foam guide.
Who it isn’t for: anyone who likes very hot coffee. Oat milk works best a little cooler.
Downsides
- No frother we checked lists an oat setting, so some trial and error is likely.
- Standard oat milk may foam poorly in any frother.
- Frothers with fixed programmes can’t be set to a precise temperature.
- Prices can change.
