I’ve been a partner forever and I’ve never heard this. It doesn’t even make sense. We put both ice and dairy in peoples’ coffee all the time and always have. As long as the dairy isn’t out of temp (and therefore potentially growing bacteria in the first place) it should be fine.

***Assuming you are talking about brewed coffee such as pike***

It’s not due to the temps. It’s because the ice will melt and dilute the drink too much and it will become too watery. The “quality” of the drink won’t be to Starbucks standard. If a customer asks, we can do it though.

If it’s milk based such as latte: it’s because of the health factor and quality factor. Putting ice in a steamed milk will affect quality of the milk and will make it bad.

I’ve been told that if it’s a black coffee it’s fine, but if it has milk in it that it can create bacteria due to the temperature.

Um. Definitely not a health risk to put literal water into coffee...smh. 🤦🏼‍♀️ we do it everyday at my store..

I’ve never heard that it’s a health risk, just that it waters down your coffee

Try asking in r/coffee

Pretty sure it’s because it puts the drink in the temperature danger zone where bacteria can grow! Not positive though.
