What happened to Bunn my Cafe MCU?
A discontinued model, the BUNN My Cafe MCU was great in its heydey. Unfortunately, that day has come and gone. But don’t despair! BUNN now makes the My Cafe MCR, which dispenses coffee from 4-16 oz in 0.25 oz increments (but has 6 oz and 8 oz default sizes) using single-serve cartridges.
What is a Bunn my Cafe MCU?
A versatile single-serve system, the durable BUNN My Cafe MCU has a 14 oz reservoir and 4 removable drawers for K-Cups, grounds, tea bags, or hot water only. Now-discontinued, check out the Keurig K-Slim instead. The Coffee Maven’s editors select and review products independently.
What happened to Bunn?
The fight was being pushed out of Bunn who could not be faulted for effort, but there was just no way back and two minutes into the sixth round he was put out of his misery as a chopping right had him down, landing outside the ropes and while he rose, that was it.
Is the Bunn my Cafe MCU water try removable?
The biggest shortcoming to note in this BUNN My Cafe MCU review — the water try is not removable. For those who frequently use their machine, this isn’t a big deal. If you only use it occasionally, though, you may not enjoy having stagnant water sit in the machine.
