I brewed for a year without measuring ABV. Here's what happened.

Not cracked. Not leaked. Exploded. I woke up thinking someone had broken in. Walked into the kitchen and found my cabinet dripping with what used to be a Belgian golden ale. Glass everywhere. Smelled incredible, tasted like regret.

My fault entirely.

I'd bottled too early because I "felt like fermentation was done." No measurements. No gravity readings. Just vibes and impatience.

Here's the thing nobody told me when I started homebrewing — ABV isn't just about knowing how strong your beer is. It's about knowing whether fermentation is actually finished. Yeast doesn't care about your bottling schedule. It will keep eating sugar inside a sealed glass bottle until something gives.

The math is stupid simple btw. Take a gravity reading before fermentation (OG), take one after (FG), subtract them, multiply by 131.25. Done. I use this ABV calculator now because it also does temperature correction automatically which — trust me — matters when your sample is warm.

Started doing this consistently around batch seven. My beer got noticeably better within three batches. Not because the formula is magic, but because suddenly I could see exactly where I was screwing up.

Ignorance feels fine until your cabinet smells like a brewery at 2am.

Measure your gravity. Every time. Don't be me.
