Overview
The Bunn GRB Velocity Brew is a 10-cup home coffee brewer with an internal always-hot stainless steel water tank, a drip-free carafe, and a multi-stream sprayhead, designed and assembled in the USA.
Bunn's home brewers work differently from most drip machines because the tank stays hot between brews rather than heating water on demand, which is what makes the roughly 3-minute brew time possible. That design means a required initial setup where the tank fills and heats before the first pot tastes right, and several reviewers describe a real learning curve in the first day or two of ownership. It's a repeat-purchase brand for a number of reviewers, some on their third or fourth Bunn over multiple decades.
- Internal always-hot stainless steel tank
- Brews 4 to 10 cups, 20 to 50 ounces
- Designed and assembled in the USA
- 3-year manufacturer warranty
Who it's for
Suits households that brew coffee daily and want speed and consistency over configurability, especially anyone replacing a worn-out prior Bunn. Casual or occasional coffee drinkers who don't want to keep the tank filled and heated between uses will find less benefit from the always-hot design.
What buyers say
From Amazon customer reviews.
Long-time owners describe this as a repeat purchase across multiple units and years, with several noting the water tank takes longer to reach full temperature during initial setup than the manual suggests, sometimes a full day. Reviewers consistently praise the drip-free carafe and front-fill design, and one reviewer noted the machine requires Bunn's specific filter size, calling it a minor inconvenience rather than a real drawback. Comparisons against other 10-cup drip machines in the reviews favor Bunn on both brew speed and taste.
Strengths and trade-offs
Drawn from this product's published specifications.
- Brews a full pot in about 3 minutes
- Drip-free carafe design reduces counter mess
- Multi-stream sprayhead for even extraction
- Requires Bunn-specific filter size
- Initial tank heat-up can take longer than expected
- Suited to daily rather than occasional use
Performance notes
The internal tank holds roughly 70 ounces of water at a near-boiling temperature at all times, so brewing starts the moment water is poured in rather than after a heating cycle, cutting full-pot brew time to around 3 minutes. The multi-stream sprayhead showers water evenly across the grounds bed, which several reviewers credit for a less bitter cup than machines that saturate unevenly. The drip-free carafe design arcs the pour into the cup and wicks residual coffee back in, reducing counter drips during serving.

Questions about the Bunn 38300.0063
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
How fast does the Bunn GRB Velocity Brew make coffee?
It brews a full 10-cup pot in about 3 minutes because the internal tank keeps water hot and ready between brews.
Does the Bunn GRB need special filters?
Yes, it uses Bunn's own filter size rather than standard basket filters, which reviewers note is easy to find but is a required accessory.
Why isn't my first pot from the Bunn GRB hot enough?
The internal tank needs time to reach full temperature after initial fill; reviewers report the first several pots can run cooler until the tank is fully primed.
