No. The Bevi machines are designed so that flavor/enhancement concentrate travels independently from each BiB (flavor concentrate box) directly to the beverage dispensing nozzle. When selected, the flavors do not mix beforehand, but are injected directly into the water stream as it leaves the nozzle.
Since the flavors do not mix inside the Bevi and use individual nozzles to infuse the water stream as it is being poured, there is no risk of residual flavors crossing over between drinks.
🪄 Tip: When dispensing a drink, the selected beverage options on-screen remain active for a few seconds before clearing. Users should observe the screen and be aware of their beverage selections before dispensing.
