Let’s dive in and find out together, exploring the science and engineering that makes this compact machine a true contender.

A Brief History of the Espresso Machine

Before we delve into the specifics of the Bambino Plus, let’s take a quick detour into the fascinating history of the espresso machine. The quest for a faster, more efficient way to brew coffee led to the birth of the espresso machine in late 19th century Italy. Angelo Moriondo of Turin, Italy, is credited with patenting the first known espresso machine in 1884. This steam-driven “instantaneous” coffee beverage making device was more of a bulk brewer. It was a significant departure from the slower brewing methods of the time.

However, it was Luigi Bezzera, in 1901, who improved upon Moriondo’s design by introducing a machine that forced water and steam through the coffee grounds at pressure. This marked the true beginning of espresso as we know it. Over the years, refinements in pump technology, temperature control, and portafilter design have led us to the sophisticated machines we see today, like the Bambino Plus. The evolution of the espresso machine is a testament to human ingenuity and our enduring love for a great cup of coffee.

Understanding the Science of Espresso: A Delicate Balance

Espresso, at its heart, is a concentrated coffee beverage brewed by forcing hot water through finely-ground coffee beans under high pressure. But it’s more than just strong coffee. It’s a complex interplay of chemical and physical processes that, when mastered, result in a rich, aromatic, and flavorful experience, crowned by the signature layer of crema.

Achieving the perfect shot requires a delicate balance of several key factors:

• Water Temperature: The ideal water temperature for espresso extraction lies between 195°F and 205°F (90°C and 96°C). This narrow range ensures optimal extraction of coffee solubles without scorching the grounds.
• Pressure: Nine bars of pressure (approximately nine times atmospheric pressure) is the industry standard for espresso extraction. This pressure forces water through the coffee puck, extracting the desirable flavors and oils.
• Grind Size: Espresso requires a fine grind, similar in texture to table salt. The grind size affects the flow rate of water through the coffee and, consequently, the extraction time.
• Tamping: Applying even and consistent pressure (around 30 pounds) to the ground coffee in the portafilter creates a uniform puck, ensuring even water distribution during extraction.
• Pre-infusion: A gentle wetting of the coffee grounds before full pressure is applied, allowing for a more even and complete extraction.

Feature Highlight: PID Temperature Control - The Brains Behind Consistent Brewing

At the heart of the Bambino Plus lies its PID (Proportional-Integral-Derivative) temperature control system. Think of this as the machine’s brain, constantly monitoring and adjusting the water temperature with remarkable accuracy. Unlike simpler thermostats that switch on and off, causing temperature swings, the PID controller uses a sophisticated algorithm to maintain a precise temperature throughout the brewing process.

How does it work? The PID controller continuously measures the water temperature and compares it to the desired set point. It then calculates the necessary adjustments to the heating element, ensuring that the water stays within a very narrow, optimal range, typically ±2°F (±1°C).

Why is this important? As we discussed earlier, water temperature is paramount for proper espresso extraction. Slight deviations can significantly impact the flavor profile of your shot. The PID control in the Bambino Plus takes the guesswork out of temperature management, delivering consistent results every time. This feature alone elevates the Bambino Plus above many entry-level espresso machines, bringing a level of precision typically found in higher-end models.

Feature Highlight: Thermocoil Heating System - Rapid Heat-Up and Consistent Performance

Complementing the PID control is the Bambino Plus’s thermocoil heating system. This system utilizes a coiled stainless steel tube to rapidly heat water on demand. As water passes through the coil, it’s quickly brought to the ideal brewing temperature.

The Science of Thermocoils: This design offers several advantages over traditional boiler systems. Firstly, it significantly reduces heat-up time. The Bambino Plus is ready to brew in a mere 3 seconds, a remarkable feat. Secondly, it improves energy efficiency by only heating the water needed for each shot. Lastly, the stainless steel construction ensures durability and minimizes scale buildup.

User Benefit: No more tedious waiting for your machine to warm up. The rapid heat-up time is a game-changer, especially for busy mornings. Plus, the thermocoil’s efficiency contributes to lower energy consumption, a win for both your wallet and the environment.

Feature Highlight: Low-Pressure Pre-Infusion - Blooming the Grounds for Optimal Extraction

The Bambino Plus incorporates a low-pressure pre-infusion stage, a crucial step in achieving a balanced and flavorful espresso. Before applying the full 9 bars of extraction pressure, the machine gently saturates the coffee grounds with low-pressure water.

The Science Behind Pre-Infusion: This gentle pre-wetting allows the coffee grounds to “bloom,” releasing trapped gases and preparing them for optimal extraction. It helps to settle the coffee bed, preventing channeling (where water finds the path of least resistance, bypassing parts of the coffee puck) and ensuring even water distribution throughout the grounds.

Think of it like this: Imagine watering a dry potted plant. If you pour water quickly, it might just run off the surface. But if you water it slowly at first, the soil absorbs the water more effectively. Pre-infusion works similarly, allowing the water to penetrate the coffee grounds more uniformly.

User Benefit: Pre-infusion translates to a more balanced and nuanced espresso, with enhanced aroma, a richer crema, and a more consistent extraction yield. It’s a subtle yet powerful feature that significantly impacts the final cup quality.

Feature Highlight: Automatic Milk Texturing - Barista-Quality Microfoam at Your Fingertips

For those who enjoy milk-based espresso drinks like lattes and cappuccinos, the Bambino Plus offers an automatic milk texturing feature that simplifies the often-tricky process of creating microfoam.

The Art and Science of Microfoam: Microfoam is not just about froth; it’s about creating a velvety smooth texture with tiny, uniformly sized bubbles. This requires precisely controlling the introduction of air and heat into the milk, breaking down the milk’s fat and protein molecules to form a stable emulsion. Achieving this manually takes practice and skill.

The Bambino Plus Advantage: The machine’s automatic steam wand takes the guesswork out of milk frothing. You simply select your desired temperature and texture level, and the wand does the rest. An integrated temperature sensor monitors the milk temperature, automatically stopping the steaming process when the optimal temperature is reached.

User Feedback: While some experienced baristas might prefer the control of manual steaming, many users praise the Bambino Plus’s automatic system for its convenience and consistency. Reviews often highlight the ease with which they can create cafe-quality microfoam, even with limited experience. One user on Amazon stated, “The auto frothing is amazing! … It made excellent quality milk!” (Matthew, Amazon Review, June 17, 2023). However, it’s worth noting that some users have reported occasional inconsistencies with the automatic system, particularly with non-dairy milk alternatives.

Feature Highlight: 54mm Portafilter - A Commercial Touch

The Bambino Plus comes equipped with a sturdy 54mm stainless steel portafilter, a size commonly found in commercial espresso machines. This is a step up from the smaller portafilters often found in entry-level home machines.

Why Size Matters: A larger portafilter allows for a wider and shallower coffee puck, which promotes more even water distribution during extraction. This can lead to a more balanced and flavorful shot of espresso.

User Benefit: The 54mm portafilter not only contributes to better extraction but also provides a more authentic espresso-making experience. It feels substantial and well-built, adding to the overall quality feel of the machine. The portafilter comes with both pressurized and non-pressurized baskets, catering to different levels of experience and grind size availability.

Feature Highlight: 15-Bar Italian Pump - The Power Behind the Pressure

While 9 bars is the recognized standard for espresso extraction, the Bambino Plus boasts a 15-bar Italian pump. This might seem like overkill, but it’s important to understand the role of the pump in the brewing process.

The Importance of Pressure: The pump is responsible for generating the force needed to push hot water through the tightly packed coffee grounds. While 9 bars is the target pressure at the group head, a higher-pressure pump provides the necessary power to overcome resistance within the machine’s internal plumbing and deliver consistent pressure at the point of extraction.

The Bambino Plus Advantage: The 15-bar pump ensures that the machine can consistently achieve the optimal 9 bars of pressure at the group head, even with variations in grind size and tamping pressure. This contributes to a more reliable and consistent extraction, resulting in a richer, more flavorful espresso. It is also important to note that the extra pressure does not translate to a faster extraction. The flow rate is regulated to ensure the right contact time between water and coffee.

User Benefit: You can be confident that the Bambino Plus has the power to extract the full potential from your coffee beans, regardless of your experience level. This powerful pump is a key component in delivering cafe-quality espresso at home.

User Feedback: Reviews generally praise the machine’s ease of cleaning. One user noted, “Easy to clean” (Matthew, Amazon Review, June 17, 2023). However, some users have mentioned that the steam wand can be prone to clogging if not cleaned regularly.

Maintenance Tip: Regular cleaning is key to keeping your Bambino Plus in top shape. Make it a habit to wipe down the steam wand after each use and run a cleaning cycle with the provided tablets every few months, or more frequently if you use the machine heavily. Using filtered water will help reduce mineral buildup and thus the need for descaling. Breville also provides descaling powder and recommends descaling when there is scale buildup in the water tank.

A Brief Note on Coffee Bean Selection and Storage

As a coffee expert, I would be remiss not to mention the importance of using fresh, high-quality coffee beans. The Bambino Plus can work wonders, but it can’t perform miracles with stale or poorly stored beans.

Bean Selection: Opt for whole bean coffee and grind it fresh just before brewing. Look for beans with a “roasted on” date, not just a “best by” date. Aim to use the beans within 5-20 days of roasting for optimal flavor. Experiment with different origins and roast levels to discover your personal preferences.

Storage: Store your beans in an airtight container in a cool, dark place. Avoid storing them in the refrigerator or freezer, as this can introduce moisture and degrade the flavor.

Addressing User Concerns: A Balanced Perspective

While the Bambino Plus has garnered overwhelmingly positive reviews, it’s important to acknowledge some recurring concerns:

• Tight Group Head: Several users have noted that the portafilter can be difficult to lock into the group head, requiring significant force. This seems to ease up over time, as mentioned by user Stuart E. Schechter in his Amazon review dated February 8, 2019. He also suggested using olive oil as a lubricant.
• Steam Wand Blockages: Some users have experienced issues with the steam wand becoming blocked. Regular cleaning, as mentioned earlier, is crucial to prevent this. User PMJ also became familiar with removing the nozzle, cleaning it, and purging to solve this issue.
• Lack of Pressure Gauge: The absence of a pressure gauge is a drawback for some experienced users who prefer to monitor extraction pressure in real time.
• No Reset for Descale Mode: User PMJ pointed out that there is no reset for the descale mode, so one must complete the cycle before doing anything else.

It’s important to weigh these potential drawbacks against the machine’s many strengths and consider your own priorities and experience level.
