I'n not sure if this happens to you, but recently we have been having leftover coffee.
We make the same amount every morning, but sometimes Ruben doesn't have any.
Throwing it away makes me feel sad and slightly guilty.
I remembered I had those glass bottles I showed you a few days ago.
So, I pulled one out, poured in the coffee, and put it in the fridge.
I enjoyed it later that evening with a mini muffin.
It was perfectly chilled.
If you ever have this issue, try it.
