How long will distilled water stay fresh not opened?

Answer 1

As anyone who has read about historical sailing ships knows, fresh water goes bad in about one week, depending on the container and environment. As every educated person knows, sailing ships always held to a coast, both to avoid getting lost, and to be able to land and reload fresh water every few days. Every grade school student knows that Columbus and his crews only survived to reach the West Indies because they were able to collect rain water on the way. Without the storms they encountered, they would never have survived two weeks on the water they brought with them. That water would have killed them all after a maximum of 10 days. Fresh water always goes bad when exposed to light and air.

Answer 2

It would last as long as you can keep the water in the bottle clean and free of germs. Water is non perishable

Answer 3

Pretty much indefinitely.
