Breville the Bambino Plus (BES500)

Espresso quality and the instrumented test

TechGearLab is the only source found that measured the machine with instruments. A 19 g dose yielded 34 g of espresso in an average of 25 seconds, and the extraction yield was 18.4% by refractometer against the 18-22% band they cite as the industry standard. Their overall score was 72 out of 100, third of 11 machines, with ease of use at 9.1 — the highest in their group — and espresso quality at 6.5. They describe the espresso as rich and creamy with good color, a mellow flavor followed by bolder notes and occasional harsher notes. Crema was weaker than ideal: the portafilter spouts have aeration inserts that introduce air, and the resulting crema had larger bubbles that dissipated quickly. There is no pressure gauge, so dialing in is by time and yield only.

Milk, steam and cleaning

The automatic wand has three milk temperature settings (Warm, Ideal, Hot) and three foam settings (Low, Medium, High), and it purges itself when you lower it. TechGearLab produced acceptable steamed milk and decent microfoam in under a minute, but could not produce quality dry foam and saw scalding and boiling at the highest setting; their advice is to use the medium presets or lower. The wand pivots front-to-back but not side to side, so pitcher angle is awkward. Descaling takes about 8.5 minutes with you present for the whole cycle, a backflush is prompted after 200 shots, and neither alert can be overridden. The drip tray holds little: TechGearLab measured 5 in of cup clearance and says the tray must be emptied each use, while Tom’s Guide reports a delayed full indicator and recommends emptying it after every use.

Durability, warranty and upkeep

Owner durability reports span under a year to 4.5 years, and they are anecdotes, not a failure rate. One owner’s first unit died within a year but was replaced under warranty with a unit still running at three to four years; another machine died at 4.5 years of daily use from scale; a heavy user at 4-8 double shots a day reports two years with no trouble; and a refurb owner reports two years with no faults. The recurring owner-side fault is the steam wand — clogging with milk or limescale, with the machine’s own blocked-wand detection cutting out mid-steam. One Australian repair shop attributes a stuck cleaning cycle to a faulty flow-meter connection that stops the board from measuring the cycle, after which the cycle cannot be re-entered. Scale is the upstream risk: Breville’s own manual warns hard water degrades flow, temperature and espresso taste, and owner advice is to fix the water rather than descale harder.

The warranty is 2 years, one of the few things here that is unambiguously better than the cheaper alternatives. No service-parts catalog for the pump, thermocoil or control board was found in this check, so the electronics are not something to count on fixing. Running costs beyond beans and milk are Breville cleaning tablets and descaling powder, which the tester treats as a separate purchase; GearLab’s model gives $0.75 per shot lifetime cost and 203 shots to recover a $500 list price.

Which model this is

This page covers the Bambino Plus, model BES500, sold in the US as BES500BSS1BUS1 and in the UK and elsewhere under the Sage brand as SES500, with black, sea salt and damson blue colorways. Don’t confuse it with the cheaper Bambino BES450, which has a manual steam wand and a smaller tank. The two share the 54 mm portafilter, PID control and ThermoJet heater, but the Plus adds the automatic steam wand, a larger tank and a three-way solenoid valve. Breville’s US page and the US manual both list ThermoJet; one UK comparison page says otherwise, and the US first-party documentation is the one to trust.

Is it worth it?

At $399.95 — where Breville’s own page sat during this check, and where a tracked low stood on 2026-09-29 against a typical $498 — this is a defensible buy. At the $499.95 list, Tom’s Guide’s verdict is that it is pricey for an entry-level machine, and it points at a $129 Casabrews 3700 and a $299 De’Longhi Dedica Maestro as comparable-spec rivals. GearLab’s own numbers support the caution: the Barista Express scored 8.0 on espresso quality to this machine’s 6.5, for a $700 list. Buy it for the automatic milk wand, the footprint and the 2-year warranty; do not buy it for craft, do not expect pressure feedback, and budget for a real grinder and for water good enough not to need aggressive descaling.
