Multiple responses are valid for how long coffee creamer may sit out on the counter. There are several coffee creamers, which is bewildering.
When it comes to how long coffee creamers last, whether or not they are made with dairy is more important.
Dairy-free products can't have any milk in them, but "non-dairy" creamers might have a very small amount of milk or milk protein.
The National Dairy Council says that UHT milk is pasteurized at a higher temperature than normal to kill all bacteria.
UHT-treated items like coffee creamers may sit unopened on a counter for a long time due to their sanitized container.
Once opened, the difference between dairy and nondairy creamers becomes less essential than liquid vs powder.
