Brewing Like the Pros

The BUNN BTXB BT BT Speed Brew 10-Cup Thermal Carafe Home Coffee Brewer mimics commercial brewing with its always-ready hot water tank. Most cafes rely on similar hot water tanks to achieve optimal and consistent brew times and temperatures when demand is high. The BUNN home brewer replicates this instant brewing capacity in your kitchen.

With hot water ready at a pro-recommended 200°F, the grounds can be saturated immediately, fully extracting flavor quickly. The shower head evenly distributes the heated water over the grounds for a balanced, robust cup every time.

Cafe-Quality Taste

While most home brewers slowly drip hot water sporadically over grounds, the BUNN machine mimics professional espresso makers with a pressurized, continuous pour over the bed of grounds. This turbulence and constant soaking optimizes contact between water and coffee.

The result is a bold, layered cup with a smooth acidity, rich mouthfeel, and enticing aromatics reminiscent of your favorite coffee shop. The insulated carafe preserves these flavors and fresh-brewed warmth for hours.

Convenient and Durable

With straightforward controls, durable stainless steel construction, and workhorse performance, the BUNN BTXB speed brewer aims to please both casual coffee drinkers and caffeine enthusiasts alike for years to come.

Rapid Brewing Technology: The Secret Behind BUNN’s Speed

The BUNN BTXB Speed Brew’s remarkable 4-minute brew time is the result of its unique internal hot water tank. This commercial-grade stainless steel tank maintains a reservoir of 70oz of water at a consistent 200°F, the ideal temperature for optimal coffee extraction.

Unlike traditional drip brewers that heat water as needed, the BTXB has hot water instantly available. This eliminates the waiting time for the water to heat up, allowing the brewing process to start immediately once you add your grounds.

The multi-stream sprayhead then evenly showers the coffee grounds with the perfectly heated water, ensuring thorough saturation and maximum flavor extraction. This pressurized spray also creates turbulence within the coffee bed, similar to commercial espresso machines, further enhancing the extraction process.

This combination of instant hot water and optimized sprayhead technology enables the BTXB to brew a full pot of coffee in a fraction of the time compared to conventional drip brewers, all without sacrificing flavor or quality.

Flavor Extraction: Mimicking the Barista’s Touch

The BUNN BTXB doesn’t just brew quickly; it brews exceptionally well. Its design is rooted in the science of coffee extraction, mimicking the techniques used by professional baristas to achieve a rich, flavorful cup.

The key lies in the combination of precise water temperature and even saturation. The BTXB’s hot water tank ensures a consistent 200°F brewing temperature, the gold standard for extracting the full spectrum of coffee flavors.

The commercial-style sprayhead plays a crucial role by evenly showering the grounds, maximizing contact between the water and coffee particles. This results in a more balanced and flavorful brew, avoiding over-extraction and bitterness.

Additionally, the sprayhead creates a gentle turbulence within the coffee bed, similar to how baristas agitate the grounds during manual brewing. This turbulence helps to evenly distribute the water and ensures that all the grounds are fully saturated, contributing to a more consistent and flavorful cup.

Versatility: More Than Just Coffee

The BUNN BTXB offers more than just rapid coffee brewing. Its versatility extends to other hot beverages and uses.

Need a quick caffeine fix on the go? The BTXB can brew a single travel mug (20oz) in just 2 minutes, perfect for busy mornings.

It also features a dedicated hot water spout, allowing you to dispense hot water on demand for tea, instant oatmeal, or other uses. This added functionality makes the BTXB a valuable addition to any kitchen.
