This is the one to get
Color: Black
I find having separate controls for temperature and foam density is critical and this model nails it. The "newer model" listed in the product description eliminates the separate controls and does not function as well. This frother also has nice features such as the ability to produce cold foam and easy cleaning. It is also extremely quiet. I've tried several mid-range electric frothers and this is the best.

So far. so good.
Color: White
This is my 3rd frother that I purchased from Amazon. The others were brand name frothers that broken within a few months of use. I won't name here (hint: begins with an N and ends with an o) This Milk frother from Maestri however works excellent. Multiple heat and drink settings and makes the perfect foam every time. I especially like how the pitcher is removable from the electric base and can be washed with out worry. easy to use. Just read the manual to understand all the settings, makes a perfect froth in less than 2 minutes. I've only had this for a few weeks but I am impressed.

Loving it so far!
Color: White, Color: White
02 Nov 2025 I've only used this twice and I already love it. My main reason for buying it is for protein hot chocolate I drink twice a day. I previously made it at the stove and that took 13 minutes of constant mixing to reach 160°. My hot chocolate is 1 cup of milk, 1 tbsp each cacao powder and panela (sugar), 1-2 tbsp collagen powder, vanilla extract, and 1 whole egg. I premix everything before pouring it into the frother because, while it may be able to handle the powders, there's no way that whisk will be able to break the whole egg enough to thoroughly blend it before it starts cooking. I'm totally fine premixing the night before and heating it in the morning. I made the first batch this morning with 2 cups of milk doubling only the cacao and sugar which brought it to just below the top max line, and it came out perfect. It was smooth and there was no burnt taste. I used the recommended hot chocolate attachments, lowest froth setting, and 160° temp setting. I had almost no froth in my hot chocolate which was perfect. I removed the pitcher as soon as it was done to prevent any burning. I checked the temp with a thermometer and the temp was actually 165°. I don't really know if that would impact the taste if there was less milk. For the 2 cups, it was still perfect. I do wish there was a little more temp control like a 150° or 155° setting. I also wish it was able to give you the temp as it was heating in case you want to pull it off just before it hit the set temp. The bottom right button is superfluous. It helps with the foam setting, but you can also simply press each of those buttons directly. Cleaning is super easy, just remove the pitcher and attachments. I love that the attachments are magnetic, but I recommend taking them out before pouring because the magnets aren't that strong. All in all, great for the price and perfect for my needs.

Outstanding machine with loads of uses
Color: Black, Color: Black
First off the TLDR: If you have an espresso machine, buy this. The Maestri 4 in 1 is a solidly built little machine that I truly enjoy using. It has a one piece stainless steel pitcher that is dishwasher safe and the spinner has a removable metal frother. So the only plastic touching your beverage is the small plastic spinner. As of January 2026, there is a coupon for $20, off making it $48 and for this price it simply cannot be beat. Now, if you’d like to know why I bought this over the Velvitiser read on. This is meant to be detailed and helpful for those looking at these two machines or wanting to get the most out of this one. First, cost did not really factor in. I mean I’m not looking to get ripped off, but I would rather wait and save for a superior machine, than purchase an inferior one that I will be unhappy with and is likely to break on me. Just getting that out of the way. Also I looked at the new hot and cold cocoa maker that comes with the hot cocoa mug and the iced chocolate milk glass, as well as a starter kit of 10 cocoa pouches, 5 hot and 5 cold. $179. So why did I get this instead? 1. The Velvitiser, while a beautiful machine (and it is pretty) uses a proprietary hook type spinner to whisk the cocoa while it heats it. Because of this, it is designed to be used with their proprietary hot cocoa packets, which is why 10 are included. You can upgrade to 40. And of course more are on the site. There are also subscription options. However this unit was specifically designed for the cocoa butter content, size of granules, and melting point of their chocolate, you cannot use ANY OTHER chocolate, powder, matcha, etc with it - and doing so VOIDS your warranty. Now people have done it, mostly after a year when the warranty runs out. But they risk burning out the motor. The Maestri on the other hand can use just about anything. As long as you don’t drop a whole azz bar of chocolate in the thing, you’re golden. So far, the chocolate I’ve used is: Cocoa powder, Ghirardelli Sweet Ground Chocolate, and Ghirardelli white chocolate which I grated. They worked beautifully and the drinks were delicious. Also, unlike the Velvitiser, “based on the Aztec Molinillo”, I can grate and use Abuelitas Mexican Chocolate. Take that! Also, this machine goes beyond chocolate, see point 3 for other options. 2. It only holds 8 oz. Well technically 9oz but it counts on 8 oz of milk and an oz of chocolate. Hope you’re not married. Or have a boyfriend. Or a big mug. I wanna make a hot chocky for hubby and me. If I’d gotten this I would have had to make the first mug, give it to him, refill with more milk, more chocolate, and wait for the machine. And let’s be honest, by the time my mug was ready, his would be empty. 😩 The Maestri holds two cups or 16oz, and if you pour that into the pitcher you are still well under the Max Fill Line. It’s plenty to share or for my biggest mugs it’s also great when I make iced drinks or soup which brings me to 3. The Velvitiser was very limited. I had my choice of hot cocoa or the next big thing, COLD cocoa newly introduced in September 2025. That’s it. And I hope you like their flavors cause they are your only options. Now I’m not gonna lie, they look delicious. And they almost had me with the banana milk. But they are clearly operating on a subscription model here. Also, I wanted more options. So the Maestri whispered cold foam and here we are. I’m glad I went with this because yes, the Maestri 4 in 1 will do cold foam. It will also do all kinds of cold drinks. If you have an espresso maker buy this. I should probably put that at the top. Mix any of your syrups or sauces with milk and hit the first button (snowflake). Cookie Butter Milk. Hazelnut Milk. I will buy banana syrup and have Banana Milk (I hope it tastes like Banana Runts), And you can use it to mix up your morning protein shake, as long as it’s not super thick (this is not a blender). I make protein coffee so this is a HUGE step up from my old crappy shaker with the little wire ball in it. Of course you can heat and foam your milk for cappuccinos and lattes, middle button. But I also take out the foaming ring and use that setting to make veggie broth, miso soup, and vegan ginger chik’n broth. As long as you don’t have veggies or other chunks in there you can heat up/cook any clear broth. The last button is the Cocoa button. I’ve made tons of stuff with that. Hot chocolate, mocha, golden milk, matcha, and even chai. Be sure to heat your water and milk using the machine, then steep your tea. Remove your tea bag or loose tea and spices before you run the machine again to add your sugar. None of this was possible with the Velvitiser. This machine looks nice on my espresso bar, I like that the pitcher is held to the base magnetically. I love how easy it is to clean. But most of all I absolutely love how versatile it is. I’ve only had it a short period of time but it has become central to my drink making. I use it each morning for my espresso, I use it to make an iced drink at some point during the day, and it’s winter so I am using it to make a broth most days as well. So yeah, glad I went with the Maestri 4 in 1. It’s my favorite new addition to the espresso station.
