Operating the Infuser is relatively straightforward. The pressure gauge and pre-infusion help produce balanced extraction and rich crema. Volumetric control allows customizing shot volumes. The steam wand makes microfoam for lattes and cappuccinos. The hot water spout heats cups.

Selecting Coffee Beans and Grind Size

A superior coffee experience starts with the right choice of coffee beans. For the Breville Infuser, it is recommended to choose freshly roasted single-origin beans and adjust the grind size according to the type of coffee desired (espresso or lighter Americano). The freshness of the beans directly affects the flavor and aroma of the coffee, while the proper grind size ensures that water flows evenly through the coffee grounds, achieving ideal extraction.


When used with a good grinder and fresh beans, the Infuser can produce cafe-quality espresso with excellent crema and bold, nuanced flavor. The steaming performance produces creamy, sweet milk, though it can be somewhat slow compared to pro machines. Overall it performs very well for a home model under $500.

The model utilizes digital PID temperature control technology to precisely manage the water temperature, avoiding fluctuations during extraction and ensuring that each cup of coffee achieves the ideal taste and aroma. PID control not only improves the consistency of the coffee but also allows users to adjust the temperature according to different coffee beans and personal preferences.

15 Bar Italian Pump

The Infuser™ is equipped with a 15 bar Italian pump, a standard feature in many high-quality espresso machines. This pump provides the necessary pressure to extract espresso, forcing hot water through finely-ground coffee beans. The high pressure ensures optimal extraction of coffee oils, flavors, and aromas, resulting in a rich and flavorful espresso shot with a thick layer of crema.

Thermocoil Heating System

The Infuser™ features a 1600W thermocoil heating system. This system rapidly heats the water to the ideal brewing temperature and maintains it consistently throughout the extraction process. Consistent temperature is crucial for optimal espresso extraction, as it ensures that the coffee grounds are evenly saturated and that the flavors are extracted consistently.

PID Temperature Control

The Infuser™ incorporates PID (Proportional-Integral-Derivative) temperature control, a digital technology that precisely regulates water temperature. PID control minimizes temperature fluctuations during the brewing process, ensuring consistent and optimal extraction for every shot. This results in a more balanced and flavorful espresso.

Pre-infusion Function

The Infuser™ includes a pre-infusion function, which involves a brief period of low-pressure water flow before the full 15 bar pressure is applied. This pre-infusion gently soaks the coffee grounds, allowing them to expand and release gases before the main extraction. This process helps to ensure a more even extraction, reducing the risk of channeling and resulting in a smoother, more balanced espresso.

Pressure Gauge

The Infuser™ features a pressure gauge that allows users to monitor the extraction pressure in real-time. This visual feedback helps users understand whether the espresso is being under-extracted (low pressure) or over-extracted (high pressure). By adjusting the grind size, dose, and tamp, users can achieve the ideal extraction pressure, indicated by the needle in the middle of the gauge, for a perfectly balanced espresso.

The Razor™ Precision Dose Trimming Tool

The Infuser™ comes with a unique accessory called The Razor™ precision dose trimming tool. This tool is designed to level the coffee grounds in the portafilter basket after tamping, ensuring a consistent and precise dose for every shot. This consistency in dosing is crucial for achieving a balanced extraction and a flavorful espresso.

Volumetric Control

The Infuser™ offers volumetric control, allowing users to program and save their preferred shot volumes for single and double espressos. This feature ensures consistency in the amount of espresso dispensed, making it easier for users to achieve their desired coffee strength and volume. Users can also manually override the programmed volumes for more control over the extraction process.

61oz Removable Water Tank

The Infuser™ is equipped with a 61oz removable water tank, which is a generous capacity for a home espresso machine. This large tank reduces the frequency of refills, making it convenient for users who brew multiple espressos throughout the day. The removable design also simplifies cleaning and refilling.

Steam Wand

The Infuser™ includes a steam wand that is used to froth milk for lattes, cappuccinos, and other milk-based espresso drinks. The steam wand is powerful enough to create microfoam, which is the finely textured milk with tiny bubbles that is essential for latte art. The wand is also adjustable, allowing users to control the steam pressure and direction for optimal milk frothing.

Hot Water Outlet

The Infuser™ has a dedicated hot water outlet that delivers instant hot water on demand. This feature is convenient for making Americanos (espresso diluted with hot water) or for preheating cups before brewing espresso. Preheating cups helps to maintain the temperature of the espresso, ensuring a better tasting and more enjoyable coffee experience.

Stainless Steel Milk Jug

The Infuser™ comes with a stainless steel milk jug, which is used for frothing milk. Stainless steel offers excellent heat conductivity and retention, which helps to better control the temperature and texture of the milk, resulting in finer and denser milk foam. The jug is ergonomically designed for easy grip and pouring, making it convenient for users to create latte art.

Extra-Tall Cup Clearance

The Infuser™ offers extra-tall cup clearance, allowing users to use taller cups or travel mugs to directly receive espresso. This design takes into account the needs of users in different scenarios, whether for daily use or takeaway, and enhances the convenience of use.

Commercial-Style Portafilter

The Infuser™ is equipped with a 54mm commercial-style portafilter, the same type used in professional cafes. This portafilter can hold more coffee grounds, contributing to a more even extraction of the coffee, enhancing its taste and flavor. In addition, the commercial-style portafilter is more durable and can withstand frequent use, extending the life of the machine.

Integrated Tamper

The Infuser™ is equipped with an integrated and removable 54mm tamper, allowing users to tamp the coffee grounds before extraction easily. The tamper features a magnetic design that can be easily attached to the portafilter for convenient access. This design not only saves space but also reduces the number of steps users need to take in the coffee-making process, enhancing the convenience of use.


The Infuser has proven fairly durable with regular maintenance. Following Breville’s cleaning and descaling instructions is important for longevity. Key weak points include potential leaks and pump issues after prolonged use. But many owners report years of consistent use with proper care and filtered water.

Accessories and Additional Features

The Breville Infuser comes equipped with a range of accessories to enhance the brewing experience. These include single and dual-wall filter baskets to suit different types of coffee grounds, a professional-quality tamper for proper coffee compression, and the Razor™ dose trimming tool for precise coffee dosing. Each accessory is designed to optimize the extraction process, ensuring that every espresso shot is perfect.


A common complaint with the Infuser is noise during operation. The vibration pump and internal thermojet heating create noticeable hums and whirs during brewing and steaming. The lack of insulation results in increased noise levels. Some owners compare it to a small blender. While not unusable, it may be distracting early in the morning.


The Infuser requires regular cleaning and maintenance for optimal performance. Breville provides clear instructions for backflushing and descaling. The manual purge function helps clean the steaming system. Users advise sticking to filtered water and descaling monthly.

The drip tray can splash during purging and may need frequent emptying. Some report the rubber portafilter gasket can become messy. Overall the Infuser isn’t too difficult to clean relative to other home espresso machines, as long as maintenance procedures are followed.

Additionally, the Breville Infuser features an auto-purge function that automatically purges the heating system after steaming, which helps reduce lime buildup and extend the lifespan of the machine. Regularly performing the cleaning and descaling guidelines provided by Breville can maximize the machine’s performance and ensure the taste of the coffee.

Use Cases

The Breville Infuser is ideal for espresso enthusiasts who want to make high-quality espresso drinks at home. It has the power and features to produce espresso shop quality results. The semi-automatic operation allows controlling shot volumes. It can make anything from straight espresso shots to cappuccinos and lattes with latte art. The Infuser is also compact enough for small kitchens.

User Feedback

The majority of positive reviews praise the Infuser for producing rich, flavorful espresso with excellent crema that rivals coffee shops. Many owners say it makes the best home espresso they’ve tasted when used properly. Fans say the pressure gauge and pre-infusion help optimize extraction. The steaming performance gets more mixed feedback - while the steam wand can produce high quality microfoam, some feel it is underpowered and too slow compared to professional machines.

Critical reviews largely focus on reliability and durability. A common complaint is water leaking from multiple areas over time. Some report pump issues and problems descaling after a year or two of use. This suggests the Infuser may not have the longevity of pricier commercial machines with its mostly plastic internals. Many advise using filtered water and following descaling procedures precisely to maximize lifespan.

Noise is another downside, with the vibration pump and steaming producing a fair amount of noise. The small water tank capacity and tricky portafilter cleaning are other annoyances owners point out. However, most agree the espresso quality outweighs these flaws given the reasonable price.

Satisfied owners say with fresh beans and dialing in the right grind, the Infuser delivers cafe-caliber drinks. They feel it is an excellent home model for under $500 compared to more expensive machines. Overall, feedback indicates the Breville Infuser performs exceptionally well for semi-automatic espresso when maintenance guidelines are followed.
