Yes, we have a year supply of that brand and like all freeze dried it lasts 25 years. Anymore than a year, you better be in the country with other resources. If not, you'll die if urban first and then suburban. We're suburban.
The trick is to have enough water supply so you don't have to eat it dry out of the can. Remember, you have 50 gallons of potable water in your hot water heater. Attach a short hose with a valve to your drain plug. If you live rural and have a stream/river, you will still need filters. Also, I just bought a Solar Oven (Google)that will heat/boil/cook as long as the Sun is out.
Last thought: If disaster is heading your way, fill up every bathtub and container you can before the water mains break. You also have drinkable water in your toiler tanks (suggest filtered). Get a 5 gallon tub and plastic bags to deal with your feces so you don't have to waste water for flushing.
I have a WaterBob in the closet. Cheap insurance for water in an emergency. All you need is about 30 minutes notice.
If you know ahead of time a storm or other short term emergency coming your way and suspect the power will be out, there are many things you can do to make life a bit more comfortable.
Fill every container you have with tap water.
Stuff the freezer with water jugs/bottles as the more that’s frozen, the longer it takes your food to thaw.
Cook up what doesn’t need refrigeration - baked goods will last a few days.
Cooked meals will last a couple days in a fridge without electricity.
Eat down on ice cream as that will melt first. Yippee!
Clean the house while you can.
Get the dishes and laundry done while there’s still water and electricity.
Sanitize the bathrooms and kitchen because you don’t want to start an emergency situation with an already dirty house.
Vacuum, sweep and mop.
Take a bath!
If you’re lucky and your trash pick up will come before a hurricane, then make sure everything that needs to be trashed is on the curb so it isn’t rotting in your house.
