The Bunn Velocity Brew GRB is a basic coffee maker that brews quickly (in under three minutes), eliminating the need for pre-programming features. However, some owners say it produces weak coffee. Durability is a major plus, with many owners saying it lasts for years.
No programming features, but fast brew times. The Bunn GRB is a basic coffee maker without advanced programming features common to many automatic drip coffee makers. It has a stainless-steel-lined water reservoir that constantly heats the water to maintain a consistent temperature, enabling it to brew a full 10-cup pot of coffee in three minutes.
The water temperature also contributes to exceptional coffee. To obtain the richest flavor without over-extracting, coffee should be brewed between 195 and 205 degrees Fahrenheit. The Bunn maintains the temperature of water stored in the reservoir at a constant 200 degrees Fahrenheit. However, the ideal brew time is approximately six minutes, so some users say this machine produces weak coffee because the grounds aren't exposed to the hot water long enough. On the other hand, owners say that because it brews so quickly, there's really no need for the ability to program it in advance.
No automatic shut-off, but easy to use and clean. The biggest inconvenience in using the Bunn GRB coffee maker is that you need to remember to turn it off because it lacks an automatic shut-off feature. The water reservoir is constantly on, so it's also wise to unplug it when you'll be gone for several days.
This coffee maker is very easy to use; simply fill the basket and turn it on. As long as the water reservoir has had ample time to heat the water and it has enough water in it to produce a full pot, it brews in three minutes. However, water does tend to evaporate from the reservoir over the course of a few days, so users suggest checking the water level regularly.
Durable product, basic appearance. Bunn's product line has a reputation of lasting for years of regular use, and this model is no exception. Many owners report owning this model for years without problems, although there are a few isolated complaints of issues such as malfunctioning electrical connections or heating elements.
There's nothing special about the Bunn's appearance. It has black housing with a stainless-steel panel on the front of its basket housing where the warmer on/off switch is located. For those who wish, the coffee maker is also available in white as the Bunn Velocity Brew GRW. Owners say it's not offensive to look at, but it doesn't have the sleek, modern look of comparable automatic drip models.
Easy-to-use basic coffee maker. The Bunn Velocity Brew GRB is basic in its operation and appearance compared to other coffee makers, but owners are mostly pleased with the speed and consistency with which it produces coffee. However, if you prefer to wake up to a fresh-brewed pot, the programmable Cuisinart Brew Central DCC-1200 (*Est. $80) is a better choice.
