Unique innovations of the Breville BDC400BSS Precision Brewer Glass Coffee Maker include the adjustable bloom time, flow rate, temperature, and special modes like Gold Cup and Cold Brew.

The coffee maker also features a unique “Steep and Release” technology. When brewing small cup volumes, the Steep & Release valve holds the water in contact with the coffee even without the glass carafe in place, ensuring optimal extraction.


The Breville BDC400BSS Precision Brewer Glass Coffee Maker is a 12-cup drip coffee maker with a 60oz capacity. It has a powerful 1650W heating system and precise PID digital temperature control. The machine is made of glass and brushed stainless steel for durability.

Features - Precision Control for the Perfect Brew

What sets the Breville BDC400BSS Precision Brewer Glass Coffee Maker apart is its level of customizability and precision. It comes equipped with:

  • Adjustable bloom time, temperature (197-204°F), and flow rate
  • Flat bottom and cone filter baskets
  • Pour over adapter for Hario and Kalita drippers
  • Auto start and keep warm features

These allow you to optimize every parameter to coax the best flavor out of your coffee. The Gold Cup mode meets SCA standards automatically.

Coffee Quality

Users praise the smooth, balanced flavor with no bitterness. The flat bottom filter yields a cleaner cup. Coffee color and crema are excellent. Temperature precision prevents over or under extraction. Coffee temperature can reach 197-204 degrees Fahrenheit to ensure optimal extraction. The Breville BDC400BSS Precision Brewer Glass Coffee Maker is suitable for various types of coffee beans, including single origin, blends, light, medium, and dark roasts, allowing you to choose according to your preference.

Brewing Type and Compatibility

This is a drip coffee machine that uses flat bottom or cone filter baskets. It is not compatible with coffee pods or capsules.

Additionally, the Breville BDC400BSS offers two types of filter baskets: a flat-bottom and a cone-shaped. The flat-bottom basket is ideal for fast, even extraction of larger volumes of coffee, suitable for robust, dark-roasted beans; while the cone-shaped basket is better for precise extractions, highlighting the unique flavors of single-origin or lightly-roasted beans.

Suitable Coffee Types

The precise temperature control allows for optimal flavor extraction from various roast levels, whether it’s light roasts with fruity notes or dark roasts with rich, chocolatey flavors. The Cold Brew mode shines for richer, smoother iced coffee.

Water Reservoir

The water reservoir capacity is unknown. The 60oz carafe allows brewing up to 12 cups at once.

Temperature Control

PID (Proportional-Integral-Derivative) control is an advanced control technology used to maintain precise temperature during the brewing process. By continuously adjusting the output power of the heating element, the PID system ensures that the water temperature is always within the set range, optimizing the extraction rate and flavor expression of the coffee. Precise temperature control is crucial for brewing coffee as it directly affects the flavor, aroma, and mouthfeel of the coffee. Water that is too hot can lead to over-extraction, resulting in bitter and burnt flavors, while water that is too cold can lead to under-extraction, leaving the coffee tasting weak and watery.


Unique innovations include the adjustable bloom time, flow rate, temperature, and special modes like Gold Cup and Cold Brew.
