Yes, one minute is the sweet spot for most of us living at sea level. Bring your water to a rolling boil—that aggressive, angry bubbling where it looks like a tiny volcano—and let it go for sixty seconds. That’s it. You can sing half of “Happy Birthday” while watching it steam. Why a minute? Because that’s how long it takes to kill the nasty stuff: bacteria, viruses, and parasites that would love to throw a party in your gut.
But What If You Live in the Mountains?
Here’s where things get slightly more complicated, like your first time using a French press. At higher altitudes—say, above 6,500 feet—water boils at a lower temperature. It’s like trying to cook pasta in a weak volcano. The CDC says you need to boil for three minutes up there. So if you’re camping in the Rockies, bring a timer. Otherwise, you might as well be sipping lake water with a smile and praying your immune system is on vacation.
Fun fact: I once boiled water for five minutes at a cabin in Colorado because I panicked. The water tasted like a rusty spoon, but hey, no dysentery. So over-boiling is safe—just annoying. It’s like overcooking a steak: you won’t die, but your taste buds will judge you.
