Bottling and Storing Cold-Brewed Coffee?
Most cold-brew advocates that I have seen actually create a coffee concentrate, that they then dilute to drinking strength.

This article from The Nourishing Gourmet is typical in indicating that the concentrate can be held for about one week; the recipe at The Chow says 5 days.  Bon Appetit is an outlier claiming you can prepare the concentrate up to two weeks ahead of time.

The general consensus is clearly that you should be able to get through the work week, in any case.
