When zombies attack or when the electric grid is taken down by an EMP or solar flare, trade must go on.

Currently, about 90% of U.S. dollars exist only digitally. Even if fiat cash remained valuable post-apocalypse, it would be pretty hard to come by.

Bitcoin and other cryptocurrencies are great, but still rely on electricity and the internet to function.

So what are the best off the grid currencies for a worst case scenario?

A currency stores the value of labor or goods that are otherwise hard to store, trade, and transport.

A Proper currency will not physically deteriorate over time. It will be widely useful, all the better if you can use it yourself, worst case scenario.

Here are the five best off the grid currencies to hoard, or have the means to create.

1. Distilled Spirits AKA Moonshine–Hard Freakin' Alcohol!

We would never advocate that you break the law, except for right now when we encourage you to break any stupid laws against brewing your own hard liquor. Or try to navigate the legal minefield of home brewing, either way.

Whiskey was the currency of choice for Western Pennsylvanians after the Revolutionary War. Instead of hauling grain to market over hill and through dale, they converted it to whiskey. This was much easier to transport and trade since it had high value for a low volume. The scumbag Alexander Hamilton ruined that by demanding a whiskey tax paid in coin. This set off the Whiskey Rebellion which set the precedent for the terribly cronyistic and centralized government we have today.

But anyway, alcohol sales are generally recession proof. Worst case scenario, you can drink your money and drown your sorrows.

Amazon actually sells a stove top distiller… FOR DISTILLING WATER you degenerates.

Another easy way to distill alcohol is by using a big pot where you slowly boil your fermented mash. Place a smaller bowl that floats in the mash, and then a larger bowl over the top of the pot. The idea is that as the alcohol boils off, it collects on the bottom of the larger bowl covering the pot, and drips into the smaller floating bowl.

If you have access to below freezing temperatures, another makeshift method is to strain the alcoholic mash, and freeze it. The water will freeze before the alcohol, so any remaining liquid is your moonshine.

Alcohol is also a great disinfectant, and preservative.

2. Ammunition. The Silver Bullet of Currency.

Just make sure your ammo is for widely used guns. I'm not sure how much your 7.62×54 Russian is going to trade for on the apocalyptic market.

Of course, your bullets could rust and deteriorate, but kept under the right conditions, they should outlive you.

It also helps if you can make your own ammunition. So go ahead and buy up a crapload of brass casings, lead, gunpowder, and a loading press.

Worst case scenario, you just bought yourself a lifetime supply of cheap bullets.

In terms of using it yourself, there is obviously protection from people and animals, but also hunting. Squirrels will start tasting like chicken pretty quick.But stick to the .22s for squirrel hunting, anything bigger and

But stick to the .22s for squirrel hunting. Anything bigger and we're talking squirrel puree.

3. Soap. This gives money laundering a whole new meaning.

If you have water, fats, and lye, you can make soap. Soap is actually pretty rare these days. Real soap is a chemical reaction between lye and fat. Most commercial soap is just chemicals and fragrance.
