Build Quality - Engineered for Longevity

Constructed with heavy-duty stainless steel, the BUNN Speed Brew Elite not only looks professional but is built to withstand the rigors of daily use.

Step-by-Step Usage Guide

  1. Prepare the Coffee Filter and Grounds: Insert a filter into the basket and add the appropriate amount of ground coffee. This setup is crucial for achieving a clean and rich coffee taste.
  2. Measure Water: Fill the carafe with the desired amount of water. This determines the amount of coffee you will brew, allowing for consistent flavor strength.
  3. Load Water into the Reservoir: Pour the measured water into the reservoir, ensuring the water level is visible through the clear window. This step is key to maintaining the precision of the coffee volume.
  4. Position the Carafe: Place the carafe below the basket to catch the brewed coffee.
  5. Initiate Brewing: Close the reservoir lid to start brewing. This action activates the brewing process, leveraging the hot water already heated to the ideal temperature.
  6. Dispense Coffee: The coffee will dispense based on the volume of water added, ensuring each brew is perfectly tailored to your needs.
  7. Turn Off the Hot Plate: After use, it’s important to turn off the hot plate to preserve the coffee’s flavor and prevent overheating, which can lead to a burnt taste.


In addition to speed, the BUNN CSB2B Speed Brew Elite doesn’t compromise on coffee flavor. Its built-in temperature-regulated tank ensures that the ideal temperature is reached for each brew, guaranteeing a rich flavor and aroma. Whether you prefer a strong, full-bodied coffee or a milder, more delicate taste, this coffee maker can satisfy your taste buds.
