The Truth About Beer Bottle Ridges

Beer bottles don't actually have exactly 21 ridges. That's a myth that's been floating around

forever. The truth is way less precise. Those ridges, called knurls,

vary wildly between brands and bottle styles. Some have 18, others have 24,

some even more. Their real purpose is just giving you grip and helping with the capping

process during manufacturing. There's no magic number that prevents leaks or cracks. Bottle makers simply

pick whatever works for their specific design and equipment. So next time someone drops this fact

at a party, you can politely correct them. “if you found this interesting,
