Coffee Quality:

Reviewers praise the smooth, flavorful coffee produced by the Breville, comparable to expert pour over results. The precise PID temperature control and adjustable bloom times extract maximum flavor from the beans.

The PID (Proportional, Integral, Derivative) temperature control is pivotal in achieving the perfect extraction. This system continuously calculates temperature variations to maintain heat within the optimal range for coffee brewing, ensuring every cup reaches the potential of its flavor profile.

Understanding the Science of Coffee Brewing: The brewing temperature and time are critical factors in coffee extraction. The optimal brewing temperature for coffee is between 195°F and 205°F. At these temperatures, the water extracts the flavors and oils from the coffee grounds efficiently without causing over-extraction or bitterness. The PID controller in the Breville Precision Brewer meticulously maintains this temperature range, ensuring each brew is as flavorful as possible. Moreover, the bloom phase—where hot water first contacts the coffee grounds—releases carbon dioxide and prepares the coffee for optimal flavor extraction, a principle well understood in the coffee aficionado community.

Temperature Control:

The PID controller enables precise temperature adjustment from 195°F to 205°F, ideal for coffee extraction.

The use of PID temperature control technology in the Breville Precision Brewer ensures precise heat management during brewing, minimizing temperature fluctuations that can affect the taste and extraction efficiency of your coffee. This leads to a consistently superior cup of coffee, regardless of the variety or origin of beans used.

Brewing Pressure:

Pressure comes from the 15 bar Italian pump, which allows modulation of flow rate.


Breville designed the first drip machine with precision PID temperature control and adjustable bloom time and flow rate, allowing specialty café style results at home.

Additional Features:

The Precision Brewer has an auto-start mode to schedule brewing. A keep warm function holds coffee at the perfect temperature.

Water Tank Capacity:

The 60oz water tank allows brewing full batches without frequent refilling. The average household can brew several days of coffee before needing to add water.


The brewing process involves some minor pump noise similar to a home espresso machine. It’s not disruptively loud.


The stainless steel construction is BPA free. The 110V-120V electrical system meets safety standards. An auto shut-off stops heating if the carafe is removed mid-brew.


1650 watts power the heating system. The power cord length is 2-3 feet.


The removable parts are dishwasher safe. Backflushing the system periodically is recommended along with descaling as needed.
For regular maintenance, ensure the removable parts such as the carafe and filter basket are cleaned after each use to prevent oil and residue buildup. Utilize a soft, damp cloth to clean the machine’s exterior and avoid harsh chemicals that can damage the stainless steel finish. Regular descaling is crucial, especially in areas with hard water, to prevent mineral buildup that can interfere with machine performance. The descaling process is simplified with the LCD prompts guiding you through each step when it’s time to descale.


Paper filters need occasional replacement. Descaling solution should be cycled through every 3-6 months to prevent mineral buildup.
