Breville Bambino Espresso Machine (BES450BSS) Review — Compact Powerhouse for Home Baristas
In today’s world of home coffee brewing, space, speed, and quality matter just as much as price. The Breville Bambino Espresso Machine (BES450BSS) aims to hit the sweet spot: a compact, budget-friendly espresso machine that heats up in seconds and still produces café-quality shots. But does it truly deliver, or is it just another entry-level appliance with limited potential?
In this in-depth review, we’ll explore every aspect of the Bambino—from design and features to performance, milk frothing, cleaning, pros and cons, and long-term value—so you can decide if it deserves a place in your kitchen.
First Impressions and Design
The Bambino lives up to its name—it’s one of the smallest espresso machines in Breville’s lineup. Measuring just over 6 inches wide, it’s compact enough to fit comfortably in tight kitchens or on crowded countertops. The brushed stainless steel finish gives it a sleek, modern look, and while some parts are plastic, the machine overall feels sturdy and well-built.
The layout is clean and intuitive. A few buttons control all functions, so you won’t be overwhelmed by menus or digital screens. It’s minimalistic in the best way, designed to give you the essentials without unnecessary complexity.
Build Quality and Durability
Despite its small footprint and relatively low price point, the Bambino feels robust. The portafilter and baskets have a solid weight to them, and the stainless steel housing suggests durability. At just over 10 pounds, it’s light enough to move easily, yet heavy enough to feel stable when locking in the portafilter.
While it doesn’t match the all-metal construction of higher-end machines, it’s more than reliable for daily home use. With regular care, the Bambino should provide years of service.
Key Features of the Breville Bambino
The Bambino’s appeal lies in its clever balance of compact design and professional-level features. Here are the highlights:
1. ThermoJet Heating System
This is one of the Bambino’s biggest selling points. Unlike traditional espresso machines that require 10–15 minutes to heat up, the ThermoJet system reaches the right brewing temperature in about 3 seconds. This means you can go from cold start to pulling a shot almost instantly.
2. 15-Bar Italian Pump
The Bambino uses a 15-bar pressure pump to extract espresso. The machine also includes low-pressure pre-infusion, gently soaking the grounds before ramping up to full pressure. This results in more even extraction and better-tasting espresso.
3. Compact Footprint
At around 6 inches wide, the Bambino is one of the most compact semi-automatic espresso machines available. Perfect for apartments, small kitchens, or anyone who doesn’t want their coffee setup to dominate the countertop.
4. Manual Steam Wand
The Bambino includes a steam wand capable of producing true microfoam for lattes, cappuccinos, and flat whites. It doesn’t have preset automatic frothing functions, which means you’ll need to learn technique—but that also means you can create barista-style textured milk with practice.
5. Stainless Steel Portafilter
The 54mm portafilter comes with both pressurized and non-pressurized baskets, giving you the flexibility to use pre-ground coffee or freshly ground beans.
6. Energy Efficiency
Thanks to the ThermoJet heating system, the Bambino consumes less energy and switches into standby mode after a period of inactivity.
Ease of Use
Breville designed the Bambino with simplicity in mind. You’ll need to grind and tamp your coffee manually (no built-in grinder), but the actual brewing process is straightforward. Insert the portafilter, choose your single or double shot button, and the machine does the rest.
Because it’s semi-automatic, you’ll need to refine your grind size, tamp pressure, and shot timing to get the best results. Beginners may need a few attempts, but once dialed in, the Bambino produces consistent, flavorful espresso.
Espresso Quality
This is where the Bambino really shines. Thanks to its combination of pre-infusion, stable brewing temperature, and adequate pump pressure, the shots it produces are rich, aromatic, and topped with a layer of golden crema.
The flavor profile is balanced and smooth, especially when paired with a quality burr grinder and fresh beans. It may not match the consistency of machines double or triple its price, but the results are far superior to most entry-level alternatives.
Milk Frothing Performance
The manual steam wand is another standout feature of the Bambino. Unlike many budget machines that include underpowered frothers, this wand has enough strength to produce silky, textured milk suitable for latte art.
Transitioning from brewing mode to steam mode takes only seconds, thanks to the ThermoJet system. Steaming small amounts of milk is quick, but larger quantities may take longer compared to commercial-grade machines. The steam wand control is simple—essentially on or off—so you won’t have fine-tuned adjustment, but the overall frothing performance is impressive for such a compact model.
Cleaning and Maintenance
Maintaining the Bambino is relatively straightforward:
-
Daily cleaning: Knock out the used puck, rinse the portafilter, purge the steam wand, and wipe down surfaces.
-
Drip tray: The tray is small, so it needs to be emptied frequently.
-
Water tank: The rear-mounted reservoir is removable for refilling and cleaning.
-
Descaling: Like all espresso machines, the Bambino should be descaled regularly to prevent mineral buildup, especially if you use hard water.
Breville includes a cleaning tool for the steam wand nozzle to prevent clogging. With basic maintenance, the Bambino is a low-hassle machine.

Who Should Buy the Bambino?
The Breville Bambino is best for:
-
Coffee lovers who want authentic espresso at home without a large machine

Beginners looking to step up from pod systems or entry-level appliances
-
Apartment dwellers or anyone with limited counter space

Home baristas who enjoy milk-based drinks and want a capable steam wand
-
Buyers seeking a balance of affordability, speed, and espresso quality
It’s not the ideal choice if you want a fully automated, one-button system or if you regularly brew multiple drinks in quick succession. For those needs, a higher-capacity machine or one with automatic frothing might be more suitable.
Value for Money
At its price point, the Bambino is a strong value. It provides café-level espresso quality, fast startup, and a reliable steam wand in a compact, attractive package. While you’ll need to invest in a good grinder to unlock its full potential, the overall setup remains affordable compared to mid-range or premium machines.
The Bambino proves that you don’t need to spend thousands—or dedicate half your kitchen counter—to enjoy high-quality espresso at home.
Final Verdict
The Breville Bambino Espresso Machine (BES450BSS) is one of the best compact semi-automatic machines for beginners and intermediate home baristas in 2025. It combines instant heat-up, consistent brewing, and surprisingly strong steaming capabilities in a small, stylish design.
It does have limitations—such as minimal adjustability and the need for a separate grinder—but for its size and price, it outperforms expectations. If you want a reliable, space-saving machine that makes real espresso and foamed milk without fuss, the Bambino is a top contender.
In short: fast, compact, and capable—an excellent choice for anyone starting their espresso journey or upgrading from pods to authentic espresso.
