Can you put coffee in a glass beer mug?

Here are a few things to consider:

* Size: Beer mugs are usually quite large, so it might be a bit much coffee for one person.

* Material: Glass mugs are fine for both beer and coffee. You can use a beer mug for iced coffee or hot coffee.

* Appearance: It might look a little unusual to use a beer mug for coffee, but it's perfectly acceptable.

Ultimately, it's up to your personal preference. You can use a beer mug for coffee if you want to!
