Bottling and Storing Cold-Brewed Coffee? I'm a bit of an iced-coffee snob – I love a good, rich tasting coffee, and love the smooth flavor of cold-brewed coffee; unfortunately, the only time I have to make it is the weekends, and it lasts for one to two days in the fridge before being consumed, leaving the rest of my week relegated to Keurig brewed over ice, or a trip to Starbucks.

I had the thought to brew coffee on Saturdays and to store it in lock-top amber bottles in the refrigerator on Sunday, but I wanted to know how long I could expect the coffee to be safe to drink? Is there anything I can do differently to extend the shelf-life of my 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.
