What Does 60 Proof Mean
But where did this whole proof thing come from? Well, it's got a pretty cool history. Back in the day, the British Navy used a technique called gunpowder testing to determine if a liquor was strong enough - if it could ignite gunpowder, it was considered proof!
This method was a bit unreliable, to say the least, but it led to the development of more modern methods for measuring alcohol content. Today, we use fancy instruments like hydrometers to get an accurate reading. It's amazing how far we've come, right?
