SCA CERTIFIED HOME BREWER LOGO
The SCA recognizes home brewers that meet their longstanding rigorous technical requirements. These requirements are based on decades of industry knowledge and research by the Coffee Brewing Center.
All SCA Certified Home Brewers have met these requirements, which are based generally on proper water temperature, brewing time, and ability to brew within the SCA Golden Cup recommendations.
If a brewer passes all of the tests in the certification procedure, as conducted by the SCA, that brewer will be eligible to be recognized as an exemplary home brewer and join the short list of SCA Certified Home Brewers.
The Breville Precision Brewer has met these SCA requirements when using the "Gold" setting and the Cone Filter basket.
Assembly
BEFORE FIRST USE
Unpack all parts and accessories before removing and safely discarding all packaging material and promotional labels. Ensure the power cord is unplugged from the power outlet.
Wipe the exterior stainless steel housing with a soft, damp cloth. Wash the lid, brew basket, cone filter insert, mesh basket filter, and carafe in warm, soapy water and a soft cloth. Do not use abrasive cleansers, pads or cloths which can scratch the surface. Rinse and dry thoroughly. Press carafe drip stop ensuring it can freely move up and down.
10
WATER HARDNESS SETTING
When first turned on, the machine will show 'HArd' on LCD, asking you water hardness level. Press SELECT dial once. Dip the water hardness test strip into the filled water tank for 1 second, remove and wait for 1 minute to reveal the result. Rotate SELECT dial and press the dial to select the level according to the number of dots shown on the strip. To reset water hardness, please refer to FACTORY RESET (page 18).
FLUSHING FOR FIRST TIME USE
1.Ensure that the empty coffee basket and empty carafe (with assembled lid) are inserted into the machine.
2.Fill the water tank with fresh cold water to the MAX mark on the water tank. Plug into power outlet and press the START|CANCEL button to turn the machine on. Rotate the SELECT dial to FAST. Press the START|CANCEL button. The machine will dispense all the water from the tank, through the system & into the empty carafe.
3. After flushing, empty the basket and carafe.
NOTE
We recommend to flush once more in Fast mode.
Operation
BREWING A CARAFE
Ensure the brew basket is clean and the drip stop seal in the bottom of the basket is clean and free of coffee particles.
1.Select the correct basket & filter for the amount of coffee you’re making. When brewing between 2 and 8 cups, we recommend you use the Cone shaped filter basket insert with paper filter (Cone paper filter is not included). When brewing more than 8 cups, use mesh basket filter or flat bottom brew basket with large paper filter.
OR 
OR
8+ CUPS
CAUTION
Filling the basket without a mesh basket filter or filter paper may cause the basket to overflow during the brewing cycle.
2.The LCD will display the basket setting - "Basket" or "Cone". To change the basket type, rotate the SELECT dial to Settings & press the dial. Rotate the SELECT dial to the basket type, press the SELECT dial to set.
3.Fill the water tank with fresh cold water up to the MAX marking on the water tank.
11
NOTE
This machine will brew all the water in the tank. Ensure the tank does not contain an excess amount of water.
4.For the very best tasting coffee, we recommend using freshly roasted whole bean coffee and grind with a burr grinder directly before you brew. The grind should be medium/coarse, never use coffee ground for espresso as your coffee basket may overflow.
5.Grind enough coffee beans for the volume you’re making. For a full 60oz carafe,
we recommend 3.5oz (99g) of coffee, approximately 12 level Breville measuring scoops. Roughly 1 scoop for every 5oz. Refer coffee/water ratio chart on page 16.
6.Insert the correct filter paper, cone or flat bottom, or mesh basket, into the brew basket, then, add your ground coffee. Insert the brew basket into the machine.
NOTE
Never use both mesh basket filter and paper filter at the same time.
NOTE
Coffee with superior taste & clarity will come from using a paper filter.
NOTE
The mesh basket filter will allow some fine coffee grounds to brew into the coffee. This will appear as sediment in the cup or carafe.
This is normal. Only use the mesh basket filter provided as others may cause the machine to overflow.
7.Lock the carafe lid and place the carafe under the drip stop outlet.

CAUTION
The carafe MUST be in place before you brew with water level higher than ‘SINGLE CUP’ line. Otherwise the coffee basket will overflow.
NOTE
Always ensure your carafe is clean and empty before brewing. Residual coffee will affect the taste and liquid in the carafe will cause it to overflow.
NOTE
Always ensure your carafe is EMPTY before brewing to prevent overflow.

8.Rotate the SELECT dial to the desired mode. Press the START|CANCEL button. The machine will display the progress:
•The machine will remind you to insert either cup or carafe where applicable
•Heating: the heating system is being pre-heated to the optimal temperature
•Blooming: the bloom phase of preparation is in progress
•Brewing: brew water at the correct/ selected temperature is being delivered to the ground coffee
9.When your coffee is ready, the machine will beep 3 times. The machine will display the “Time since brewed”.
NOTE
Never fill the water tank once the coffee machine has started a brewing cycle.
BREW MODES
•FAST: This mode is to deliver the fastest brewed coffee. This coffee machine is one of the fastest 12 cup (60oz) brewers.
•GOLD (recommended): This mode has been certified by the SCA (Specialty Coffee Association) to meet their rigorous technical requirements using the cone filter basket.
•STRONG: This brewing mode delivers a stronger tasting coffee.
•MY BREW: Allows you to customize every brew setting.
•Bloom Time: Coffee bloom occurs when hot water hits the ground coffee. This setting allows you to adjust how long the bloom time lasts. We recommend 30-60 seconds. During this time the brewing cycle pauses to allow coffee to naturally bloom. See ‘TIPS’ for more about Bloom Time.
•Brewing Temp: You can adjust the temperature of the brew water being delivered to the ground coffee to suit your favorite coffee. See “TIPS” for more about setting brew water temperature.
•Flow Rate: You can adjust brewing time to control contact time by adjusting the water delivery speed. Choose between Slow, Medium, and Fast (default).
•Pour Over: If you are using the Pour Over Adapter, this must be turned on.
(Included in BDC455 only. Sold separately at Breville webpage).
•OVER ICE: This is to make stronger coffee for ice coffee.
•Fill the water tank with the amount of water you want to brew up to 20oz line and start brewing. After brewing, pour over ice. See ‘TIPS’ for details.
•COLD BREW: Cold Brew coffee is brewed differently to traditional coffee. It uses cold, not hot water. Your brewer uses the “Full Immersion” method of brewing cold brew which steeps the water and coffee together over an extended duration – typically between 4 - 14 hours. This method creates an intense smooth coffee with little bitterness. Brew ratios are also different, and much higher than normal. Breville recommends
a brew ratio 2-3 times higher than average, approximately 3 Breville scoops to every 5oz of water.
•See ‘TIPS’ for step-by-step guide of brewing Cold Brew.
•Brew time is adjustable.
NOTE
OVER ICE mode and COLD BREW mode will be disabled if there is more than 20oz of water in the tank.
13
SINGLE CUP/SMALLER VOLUMES (LESS THAN 4 CUPS, 20OZ)
1.Your Breville Precision Brewer will recognize when the brewer has less than 4 cups (20oz) of water & will adjust the brew settings, automatically, to make the best possible tasting coffee. Fill your
cup with fresh cold water and then pour it into the water tank, ensuring the water level stays below the SINGLE CUP line.
NOTE
DO NOT fill the water tank more than SINGLE CUP line or the volume of the cup used to receive the coffee. It will overflow as the machine brews until the water tank becomes empty.
2.Place your empty cup underneath the brew basket outlet.
3.We recommend using cone filter basket insert for single cups. It ensures proper contact between the brew water and the ground coffee.
4.To change the basket type, rotate the SELECT dial to Settings and press to enter the Settings mode and select "Basket Type".
5.Rotate the dial to select “Cone”, and press dial to select. “Cone” will be displayed on the LCD.
6.Insert the Cone filter basket into the brew basket. Use the alignment marks as a guide.
7.Place a cone shaped paper filter into the cone filter basket.
8.Grind the correct amount of whole bean coffee for the amount you are brewing. 1 level Breville scoop of ground coffee is suitable for 5oz (150ml) of water.
9.Select desired brewing mode, Fast, Gold, MyBrew or Strong.
10.Press START|CANCEL to begin brewing.
