Breville the Bambino Espresso Machine – Brushed Stainless Steel, BES450BSS1BUS1

Product Overview

Breville the Bambino is a compact semi-automatic espresso machine designed for preparing espresso and manually textured milk drinks at home. The configuration associated with ASIN B0B1JPPG2L is the brushed stainless steel U.S. model BES450BSS1BUS1, also identified by UPC 021614803269.

The machine uses Breville’s ThermoJet heating system, which reaches its operating extraction temperature in about three seconds. Espresso preparation uses a 54 mm portafilter with single-wall and dual-wall filter baskets. The brewing process includes low-pressure pre-infusion followed by approximately 9-bar extraction from a 15-bar pump. Electronic PID temperature control is used to maintain more stable brewing temperature.

A manual steam wand is included for texturing milk for drinks such as cappuccinos, lattes, and flat whites. The front controls provide preset one-cup and two-cup volumetric shots, steam activation, and hot-water delivery. A removable 47 fl oz water tank supplies brewing, steaming, and hot-water functions. The Bambino does not include a built-in coffee grinder, so appropriately ground coffee must be supplied separately.

Technical Specifications

ThermoJet Heating System

The ThermoJet system is designed to bring the machine to espresso-brewing temperature in approximately three seconds. This reduces the initial warm-up period compared with many traditional boiler-based machines.

Fast system readiness does not remove the need to manage other temperature-sensitive components. Running hot water through the portafilter and cup can help warm those parts before extraction when desired.

Espresso Extraction

The Bambino begins extraction with low-pressure pre-infusion. This gently wets and expands the ground coffee before full extraction pressure is applied.

Breville specifies approximately 9-bar extraction delivered by a 15-bar pump. The machine’s electronic PID system helps regulate brewing temperature, while final espresso quality also depends on grind size, dose, tamping, coffee freshness, and technique.

54 mm Portafilter System

The machine uses a 54 mm portafilter and includes both single-wall and dual-wall filter baskets. Single-wall baskets are intended for users controlling grind, dose, and tamp with freshly ground coffee.

Dual-wall baskets provide additional flow restriction and can be more forgiving when using pre-ground coffee or coffee with less precise grind consistency.

Milk Steaming

The Bambino uses a manual steam wand rather than the automatic milk system found on the Bambino Plus. The user controls the position of the milk jug, aeration, temperature, and texture.

The steam wand can create microfoam suitable for milk-based espresso drinks and latte-art techniques. Milk residue should be wiped from the wand promptly after steaming and the wand should be purged after each use.

Hot Water Function

The Bambino dispenses hot water through the steam wand when the hot-water control is selected. This function can be used for Americano-style drinks or warming cups.

Hot water and steam can cause burns. Cups and containers should be positioned securely before activating either function.

Control Interface

The front control panel includes dedicated buttons for one-cup extraction, two-cup extraction, hot water, and steam. The espresso buttons use volumetric dosing and can also be programmed for customized shot volumes.

Water Tank

The removable rear water tank has a capacity of 47 fluid ounces, equivalent to approximately 1.4 liters. The tank should be filled with potable water to the indicated maximum line.

Breville advises against using liquids other than water in the reservoir. Milk, cleaning chemicals, coffee, or flavored liquids should not be placed in the water tank.

Product History

Breville introduced the Bambino as a compact alternative within its home espresso-machine range. The BES450 was designed around a small countertop footprint while retaining Breville features such as low-pressure pre-infusion, PID temperature regulation, volumetric shot control, and manual milk steaming.

The Bambino is related to the Bambino Plus, but the two models use different milk-steaming systems. The Bambino uses a manually controlled steam wand, while the Bambino Plus adds automatic milk texturing functions.

The BES450 remains part of Breville’s compact espresso-machine family and uses the company’s 54 mm portafilter ecosystem.

Customer Feedback Summary

This section summarizes recurring themes in publicly available customer feedback and independent evaluations. These observations are subjective experiences and are not verified product specifications.

Positive feedback commonly focuses on the rapid ThermoJet heat-up time. Users often report that the short startup period makes the Bambino convenient for preparing one or two drinks without the longer warm-up associated with some traditional espresso machines.

The narrow footprint is another frequently praised characteristic. Owners with limited counter space often value the machine’s compact width, particularly when pairing it with a separate grinder.

Espresso performance is generally viewed favorably when the machine is paired with appropriately fresh coffee and a capable grinder. Users frequently note that the included single-wall baskets provide greater control, while dual-wall baskets make pre-ground coffee easier to work with.

The manual steam wand also receives positive feedback for its power relative to the machine’s small size. Users who learn manual milk texturing often report satisfactory microfoam for cappuccinos, lattes, and similar beverages.

Reported limitations include the lack of a built-in grinder and automatic milk texturing. Users seeking an all-in-one or more automated system may find the additional grinding and steaming steps less convenient.

The lightweight, compact construction can also require one hand to stabilize the machine while inserting or removing the portafilter. Some owners additionally mention the need for regular cleaning around the steam wand and drip tray because of the small overall footprint.
