Freezing brewed coffee

1

The other day, I had stupid idea:

What if I made my coffee in big batch and freeze what I did not manage to drink?

Let's put away why would I even want to do it. And for sake of argument, I know it is probably bad idea, but still:

Why is it bad idea?

Freezing the coffee in an ice cube tray makes for a non-diluted cup of iced coffee later. – Peter H – 2015-03-27T20:52:35.423

This is a perfectly good idea, if you freeze the coffee as cubes and plan to use them to chill your iced coffee without watering it down.

If you plan to simply freeze the coffee for drinking later I can imagine it being a bad idea, because you will lose some of the flavor. If you even poured milk or cream into the coffee you're planning to freeze, I would even recommend less freezing it, because no kind of milk products can be safely frozen and those are always better used fresh.

5There are no safety issues or even necessarily quality issues about freezing milk products (beyond the typical frozen-food freshness dates), so that is not correct. And saying the coffee will "lose some of the flavor" I thought was implied by the question. The author I assumed wanted to know why and perhaps to what effect. – Robert Cartaino – 2015-03-11T14:00:19.783

@RobertCartaino There are various sites claiming that thawed milk is not quite as desirable for drinking as fresh milk, the texture will become grainy and you may not be satisfied with the end result. This article states, that also the flavor of the milk my be affected. I guess flavor-loss through freezing is a common problem with any product. This question on cooking SE may provide an answer.

@Alex No health risks though, right? (And is there any product which does not suffer from being frozen?) – Dr Eval – 2015-03-11T17:30:14.330

@Poldie If it's still good when freezing it (check best before: xyz, there's no health issue. I don't know about a product that does not suffer quality when freezing, but in the linked question there are some points on how to freeze correctly to keep quality issues at a minimum. – Alex – 2015-03-11T18:16:38.017

Water dissolve the coffee powder, and as the water gets cooler it's capability to dissolve diminishes. This means that the slower you cool the coffee the more coffee-grounds you'll get at the bottom.
