The Breville Precision BDC455 comes in a brushed stainless-steel exterior, making it durable. 

Not only that, but the material also gives the coffee maker an elegant look and feel. 

The BDC455 has a long, narrow base that supports the coffee maker’s heating system and the thermal carafe

A 60-oz. water reservoir sits directly on top of the heating system, and it can brew up to 12 cups of coffee in one sitting. 

The water reservoir is also labeled, so you will know how many cups you are potentially brewing. 

This coffee maker also comes with a massive filter basket that can cater to both cone-style and flat-bottom style filters. 


Being one of Breville’s top-of-the-line coffee makers, the Precision BDC455 comes with the latest technology that enables it to brew a yummy batch of coffee every time. 

This coffee maker comes with a proportional, integral, derivative (PID) controller and a thermo-coil heating system for precise temperature control.

The BDC455 features a motorized pump with three flow rates for optimum contact time. 

Another impressive thing about Breville’s BDC455 is how it pre-infuses and blooms the coffee grounds for optimum extraction. 

Its “showerhead” technology means that the coffee machine evenly sprays water over the coffee grounds in the filter. 

Then, the “steep & release” technology holds the coffee grounds in the brewing chamber to steep them a bit in the water. 

As a result, the coffee grounds can “bloom” for a while to get their full flavor. 

What is nicer is that you can fully adjust these settings to your liking. 

Brew Settings 

The Breville Precision BDC455 provides six brewing modes – five presets and a setting for your customized cup of coffee. 

Here are the preset coffee modes: 

Gold Cup 

In “gold cup” mode, the BDC455 brews coffee according to the Specialty Coffee Association’s standards. 

Here, the coffee machine automatically adjusts the temperature and brewing time, and all you will need to do is follow the proper coffee-grounds-to-water ratio. 

Cold Brew 

Cold brews are increasingly becoming popular these days due to their unique and complex flavor. 

However, making a cold brew can be difficult. 

Luckily, the Breville BDC455 comes with a “cold brew” setting for your convenience. 


Normally, it takes the Breville Precision coffee maker takes about six to eight minutes to pour a pot of coffee. 

However, “fast” mode cuts brewing time to half, only taking about three to four minutes. 

Strong Brew 

As in its name, the “strong brew” automatically increases temperature and lengthens brewing time for a stronger cup. 

You can further strengthen its taste by adding more coffee grounds. 

Over Ice 

The “over ice” mode makes an even stronger and more concentrated brew to counteract the ice’s melting effect. 

My Brew 

The “my brew” mode enables you to make your customized cup of coffee. 

Here, you can tweak various parameters such as the brew time, bloom time, temperature, water flow rate, etc. 

Aside from these modes, the Breville BDC455 also has a “pour over” mode. 

However, this requires you to purchase the pour-over adaptor, which some users find expensive. 

Filter Options 

The Breville BDC455 has three filtering options. 

The reusable mesh filter is ideal when brewing large quantities. 

However, the machine also provides ten paper filters which many users prefer since it gives a cleaner brew. 

The cone filter is for smaller brews, accommodating up to eight cups of coffee.


Who is it for? 

The Breville Precision BDC455 is indeed an impressive coffee maker with its high-tech features and technology. 

With its adjustable settings, this coffee maker is more suited for those who like to experiment and tweak with their coffee cup. 

Many recommend the BDC455 for aspiring baristas or more advanced coffee machine users. 

Potential Drawbacks 

A potential drawback would be that the Breville BDC455 is not the cheapest coffee maker in the market, considering its features. 

Moreover, the BDC455 can be a bit overwhelming, especially for beginners.

Its various options and settings can mean some coffee drinkers might need a bit of time to get used to it. 


The Breville Precision BDC455 is one of pride and joy.  Its features entail versatility and adaptability as users can fully tweak and make a coffee cup to their liking. 

Regardless of a customized cup or not, this coffee maker’s advanced technology ensures that every cup you brew is up to standard. 



How to clean and maintain the Breville Precision BDC455? 

The Breville Precision BDC455 is easy to clean due to its brushed stainless-steel exterior. 

All you need to do is wipe down the machine using a soft cloth while you can wash the removable parts with soap and water. 

This coffee maker also comes with a “descale” indicator to let you know when it needs descaling. 

How to descale the Breville Precision BDC455? 

To descale the BDC455, first, turn the machine off and remove the water tank. 

You can use a descaling solution or a 50-50 mixture of distilled vinegar and water and pour it inside the water reservoir. 

Turn the coffee maker for it to brew out the mineral build-up. 

Repeat the entire process until the water becomes clear. 

Compared to other coffee makers, the Breville BDC455 only takes about 15 minutes to descale.
