The Breville Bambino Plus BES500BSS is the smallest semi-automatic espresso machine Breville makes, at just 7.7 inches wide. It uses the same ThermoJet 3-second heating system as the Barista Pro and adds an automatic milk frother with 3 temperature and 3 texture settings. No built-in grinder, no LCD display, no fancy interface. The pitch: a compact, no-nonsense espresso machine for people who already have a grinder (or plan to buy a good standalone one) and want quality espresso without giving up half their counter.

The Bambino Plus is the smartest espresso machine purchase in the Breville lineup for anyone who already owns a quality grinder. You get the same ThermoJet heating element and PID control as the Barista Pro for $300 less, plus an auto-frothing milk wand that turns out workable microfoam without technique. The 7.7-inch footprint is the smallest in Breville's semi-automatic line. The tradeoffs are real: no built-in grinder (you supply one), no hot water spout for Americanos, single boiler workflow, and the proprietary 54mm portafilter. But the espresso quality ceiling, paired with a quality grinder, is genuinely close to machines twice the price. If you have $450 and a Baratza Sette 270, you have a setup that pulls shots most coffee shops would envy.
Bottom Line: Best compact espresso machine if you have a grinder. If you do not, the Barista Pro at $750 is the more sensible all-in-one. The Bambino Plus rewards good grinders ruthlessly - pair smart.

This is where the Bambino Plus surprises people. The same ThermoJet heating element and PID system used in the $850 Barista Pro pulls clean, balanced shots in the Bambino Plus chassis. The 19-bar pump is regulated down to 9 bars at the group head (standard extraction pressure). Pre-infusion soaks the puck before full pressure hits, reducing channeling. Temperature stability is ±2°F shot-to-shot, slightly worse than the Pro's ±1°F but better than the Express's ±3-5°F.
The catch: shot quality is almost entirely dependent on your grinder. With a Baratza Encore ESP ($250), you get acceptable medium-roast shots. With a Baratza Sette 270 or DF54 ($350-400), you get clean light-to-medium roast extractions. With a Eureka Mignon Specialita or Niche Zero ($500-700), you get shots that hold their own against $1,500-2,000 setups. The Bambino Plus does not limit your espresso ceiling - the grinder you pair with it does.
Same 3-second cold-start heat-up as the Barista Pro. From the moment you press the power button, the machine is ready to brew before you finish dosing into the portafilter. Brew-to-steam transition takes another 3-5 seconds. This is the single biggest workflow advantage over traditional boiler machines and the standard Barista Express. You stop pre-heating; you just turn it on and use it.
The PID-regulated ThermoJet also means shot temperature stays consistent across a session. Your fifth shot tastes like your first - assuming the same grind, dose, and beans.
The feature that distinguishes the Bambino Plus from the cheaper Bambino. The auto-frother is a single-button milk steaming system with two adjustments: milk temperature (3 settings, roughly 122°F / 140°F / 158°F) and texture (3 settings from flat white to cappuccino). You insert the steam wand into a milk pitcher, press the button, and walk away. The wand textures the milk to your selected temperature and foam level, then shuts off automatically.
Results are workable but not artisanal. The auto-frother produces consistent flat whites and lattes with passable microfoam. Cappuccino foam is acceptable but lacks the glossy stretch of barista-textured milk. For most home users who do not want to learn manual steaming, the auto-frother is good enough that you stop missing the manual control. For experienced baristas, switching the wand to manual mode is straightforward and gives you full control.
In manual mode, the steam wand produces respectable pressure for a single-boiler compact machine. You can texture 8-12 oz of milk for flat whites and small lattes. The single-boiler limitation applies: 5-10 second transition between brew and steam temperatures, and no simultaneous brewing-and-steaming. For 1-2 drink sessions this is invisible. For 4+ drinks back-to-back it gets slow.
Low learning curve for the machine itself - it does few things and does them simply. Dose, tamp, brew. Auto-frother for milk. The real learning curve is on the grinder side. The Bambino Plus rewards consistent dosing (weigh your shots), even tamping, and proper grind adjustment, just like any other semi-automatic machine. With a quality grinder and basic technique, most users pull good shots within 1-2 weeks of daily practice.
Same chassis, same ThermoJet, same espresso quality. The Bambino (BES450) at $300-400 has a manual steam wand only - no auto-frother. The Bambino Plus (BES500) at $450-500 adds the automatic milk frother with 3 temperature and 3 texture settings.
Verdict: If you are confident steaming milk manually, save $150 with the standard Bambino. If you want push-button milk for lattes and cappuccinos, the Bambino Plus auto-frother earns the premium.
Same ThermoJet heating element, same PID, comparable espresso quality. The Barista Pro adds a built-in conical burr grinder, LCD display, hot water spout, and larger 2-liter water tank for $300 more. The Bambino Plus saves money and counter space if you already own a grinder.
Verdict: Already own a grinder? Buy the Bambino Plus, save $300. No grinder? The Pro's all-in-one design saves you a separate grinder purchase. Pair the Bambino Plus with a $400 grinder and your total cost matches the Pro - but you get a much better grinder than Breville's integrated unit, and the grinder survives future machine upgrades.
Different machines entirely. The Gaggia Classic Pro ($450) is a traditional boiler single-boiler machine with a 58mm portafilter, commercial-grade components, and a massive modding ecosystem. The Bambino Plus uses modern ThermoJet inline heating and proprietary 54mm portafilter.
Verdict: Bambino Plus is the modern, convenient choice. Gaggia is the enthusiast, upgradeable choice. Both are valid at the $450 price point.
The Breville Bambino Plus is the smartest compact espresso purchase Breville sells, but only for the right buyer. If you already own a quality grinder, this machine punches well above its $450-500 price tag and produces espresso comparable to setups twice as expensive. If you do not own a grinder, the Barista Pro or a Gaggia Classic Pro plus standalone grinder are better routes. Pair the Bambino Plus with the best grinder you can afford and you have a setup that grows with you for years.
No. The Bambino Plus has no built-in grinder - you supply pre-ground coffee or grind separately. If you do not own a grinder, factor that cost in: a quality starter grinder like the Baratza Encore ESP is $250, bringing your total to $750. At that point the Barista Pro ($750-850) with built-in grinder is the better all-in-one. The Bambino Plus only makes financial sense if you already own a grinder or plan to invest in a high-end standalone unit.
The Bambino (BES450) is the entry-level model at $300-400. It has the same ThermoJet heating and 19-bar pump but uses a manual steam wand. The Bambino Plus (BES500) at $450-500 adds the automatic milk frother with 3 milk temperature and 3 texture settings. If you are confident steaming milk manually, save $150 with the Bambino. If you want push-button milk frothing for lattes and cappuccinos, the Bambino Plus is worth the upgrade.
Real espresso quality, with caveats. The 9-bar extraction pressure (regulated down from the 19-bar pump) and ThermoJet PID-controlled heating produce clean, balanced shots when paired with a quality grinder and fresh beans. Many serious home espresso enthusiasts use Bambino Plus units as their daily driver. The caveats: 54mm proprietary portafilter, single boiler with no simultaneous brew-and-steam, and dependence on whatever grinder you pair with it.
Budget pairing: Baratza Encore ESP ($250) - acceptable for medium roasts and beginners. Mid-range: Baratza Sette 270 ($400) or DF54 ($350) - stepless adjustment, much better for light roasts. Premium: Eureka Mignon Specialita ($500) or Niche Zero ($700) - reference-quality grind consistency. The Bambino Plus reveals what your grinder can do - pair it with a poor grinder and you get poor espresso; pair it with a quality grinder and you get shots competitive with $1,500 machines.
Approximately 3 seconds from cold start to brew-ready, using the ThermoJet inline heating element. Switching from brew temperature to steam temperature takes an additional 3-5 seconds. This matches the Barista Pro's heat-up time and is dramatically faster than the standard Barista Express (30-45 seconds) or traditional boiler machines (3-5 minutes from cold).
Yes, with varying results. Oat milk (especially barista blends from Oatly or Minor Figures) textures well and produces good microfoam. Almond milk steams adequately but tends to separate and produces thinner foam. Soy milk performs reasonably but can curdle at higher temperatures. Coconut milk produces inconsistent results. For best non-dairy texturing, use barista-formulated oat milk and set the auto-frother to the lower temperature setting (140°F vs 160°F).
Yes, but with a workaround. The Bambino Plus does not have a dedicated hot water spout. To make an Americano, run hot water through the empty portafilter (no coffee) using the brew button, or use a separate kettle. Most Bambino Plus owners use the kettle method for cleaner results. This is one of the few features the Barista Pro has that the Bambino Plus lacks.
Yes. Reddit's r/espresso community has multi-year tracking threads showing Bambino Plus units pulling clean shots after 5+ years of daily use with proper descaling. The ThermoJet element is less prone to failure than traditional boilers because it heats water on demand rather than maintaining a heated reservoir. Regular descaling every 2-3 months (or when the descale light activates) is the main maintenance requirement.
No. The Bambino Plus uses Breville's proprietary 54mm portafilter, same as the rest of the Barista lineup. This limits your accessory ecosystem - you cannot use standard 58mm baskets, IMS precision baskets, or most aftermarket tampers. Breville-compatible 54mm accessories are available, but the selection is narrower than the 58mm market.
Depends on grinder ownership. If you already own a quality grinder, the Bambino Plus at $450-500 matches the Barista Pro's espresso quality at half the price. If you do not own a grinder, the Barista Pro's built-in unit saves you from buying one separately. Total cost ends up similar either way, but the Bambino Plus path gives you a better long-term grinder that you can use with future machines. Most experienced espresso buyers recommend the Bambino Plus plus a standalone grinder for the upgrade path it preserves.
