How Long Does Hardtack Last and How to Store It

During the Civil War, a warm cup of coffee and a few pieces of hardtack might have been the day’s meal before marching and fighting. The poor storage conditions meant that the hardtack was not only particularly HARD, but also infested with beetles.

Dipping hardtack into coffee was a process that helped with two things:

  1. It softened the rock hard ration
  2. It made the bugs scurry out of the biscuit

This is an example of hardtack storage at its worst. There are several reasons that modern hardtack is much better.

You can store hardtack a few ways to ensure that it lasts a very long time and is still edible when you need it most. In modern times, your hardtack can act as a vehicle for other spreads and foods. It was the sheer lack of resources that forced people to eat only hardtack during tough times.

Let’s look at how we can store hardtack for even longer than 2 years!

A stack of dry hardtack can be vacuum sealed. The hardtack can even be wrapped in paper towels, and then vac-sealed to last for at least 5 years. This means you can stack this hardtack up in the pantry or even in a designated Tupperware container.

You could also use Mylar bags to store your hardtack for the long term. By using Mylar bags, you can store more hardtack together in one spot. I would recommend nothing bigger than a 1-gallon bag.

Add an oxygen absorber to each Mylar bag and fill them up with a decent amount of headroom. These Mylar bags can then be sealed using a hair straightener or an iron. These bags are heat-sealed, which is a great feature.

Mylar bags and oxygen absorbers are the same items used to store long-term food like rice and oats.

To take it one step further, you could even store several of those Mylar bags of hardtack into a plastic bucket with a lid. This keeps the Mylar bags safe from puncture, and also keeps the hardtack protected from being crushed.
