We do that coffee thing too.Drink out of mason jars so if you want to save the rest of your drink for later you can screw the lid on and place it in the fridge without worrying about it spilling.
Another similar tip, put any extra coffee left over from brewing in the fridge. You can use it later for iced coffee or to bake with.
We used to brew coffee specifically to make iced coffee (even though we always have extra in the mornings) and then sit there like idiots while we wait for it to get cold in the freezer or become impatient and water it down with ice. You live and you learn.We do that coffee thing too.
