Thermojet Heating System: Instant Readiness for Espresso Enjoyment
A standout feature in the Breville Bambino BES450BSS is its rapid thermojet technology. The machine is extraction-ready in just 3 seconds, a serious game-changer for busy mornings or quick coffee breaks. No need to wait several minutes or pre-plan your cup.
Real-world benefit: Many users report making several espressos in succession with minimal heat lag—a true advantage for households or offices with multiple coffee drinkers.
Automatic Microfoam Milk Texturing for Effortless Lattes and Cappuccinos
With its automatic steam wand, the Bambino lets you set milk temperature and texture to your liking. It creates barista-style microfoam, key to latte art and flavor harmony in milk-based drinks.
Common question: Can beginners get good results? Absolutely. The auto feature reduces guesswork, so you won’t struggle with scalded milk or inconsistent foam.
Low Pressure Pre-Infusion: Smoother, More Balanced Espresso Shots
Set your shot up for success with the Bambino’s low pressure pre-infusion, which gently introduces water to the coffee for even grounds saturation. This helps avoid bitter or weak pulls.
For example, users consistently note rich crema and smoothness—even with budget or pre-ground coffee.
Digital Temperature Control (PID): Consistency You Can Taste
The built-in PID controller delivers water at the right temperature every time. This technology is often reserved for higher-end coffee machines.
The result is a reliable, repeatable shot—helpful if you want your morning espresso to taste the same each day.

Review Feedback Highlights
This machine is amazing for its size. It heats up in seconds and makes rich, smooth espresso with perfect crema every time. The steam wand works great for lattes and cappuccinos, and cleanup is super easy. The stainless steel build feels solid and looks great on the counter. Perfect for anyone who wants café-quality coffee at home without taking up much space.
The media could not be loaded.Well, allow me to say, this is the first machine I have had since the 1980s was it and that one Hoovered. Finally tried a unit, one of the many seemingly all variants of the same 51mm units. I had to send it back because, while very nice at the price point I feel it (and they) are probably best – and aimed at – milk coffee drinks and not actually espresso.Some, seems all similar did, have something the Bambino lacks – more metal. In feel (if there is such a thing) they, or at least mine – felt substantially more robust. It felt actually like better quality. But I couldn’t adjust the water and couldn’t get enough coffee in the portafilter. Maybe, some other options would fit the 51mm unit. I couldn’t confirm it.This unit has a lot of plastic in it including the group head. BUT! It can adjust/learn pump-run time (adjust the water volume indirectly). The temperature is non adjustable. But I don’t think water temp (as long as it is very near boiling) is really a variable most home espresso drinkers would benefit from – especially the beginners and novices.With the thermocoil design I understand it has, it heats in like 3 literal seconds. Steam is good (but I drink simple espresso so I am honestly not much help in evaluating that part). The wand has good articulation.I do like that Breville is big enough that plenty of 54mm baskets, portafilters, screens and papers are available – including bottomless.While I do like the unit’s function and it has everything I wanted, it does feel cheap for the value proposition. I don’t think it will hold up well for the length of time I keep appliances. It might. But, I do worry that the fact it knows how long it has been powered up/plugged in – makes me wonder if Breville embedded a count-down timer to planned obsolescence. I hope not, but the manual is clear in disclosure that it’s recording usage data.I added a picture of three pucks/cakes (whatever term you like) within the first 24hours of receipt. The two dark ones were with pre-ground 6 month old (or longer) coffee and the third was with Folgers Classic drip grind.Yes, I do wish the entire Breville line was built on a standard 58mm group head (I do prefer a thinner cake per dose). And I do worry if it has an internal count-down to death timer and if the plastic will hold up.Edit: (added a bottomless portafilter and IMS basket)They — finally — came today. While these are aftermarket non-Breville parts, I added a video of a shot. (Replaced that because it was a little dark – new video has a little spurt – welcome to aftermarket bottomless portafilters. It happens sometimes)I don’t claim to be an expert since it’s been 35, idk 40ish years since I have had an espresso machine. I’m just now re-learning how to do it (or learning this machine); but, since I detest coffee snobs who discourage much more than they impress, I wanted to share.No, I’m sure it’s not
