Recapping Beer for a Special Occasion
Now that you can get custom bottle caps, why not take any beer and recap it for a special occasion? Weddings, bachelor/bachelorette parties, birthdays, corporate events, awesome parties: they all deserve memorable caps.
But can you recap a commerically purchased beer without the beer going bad? Wouldn't it lose carbonation and flavor? BottleMark conducted a two-week long experiment to find out. The answer? Yes, you can! IF you follow a few precautions...
Recapping Experiment Summary

We purchased a craft beer six-pack, recapped three bottles, and left three bottles untouched. We tested at three time intervals: four days after recapping, one week, and two weeks. At each interval, we opened one control and one recapped beer and compared carbonation and taste. Results?

How To Recap a Beer
What you need:
- Beer
- Bottle Capper (available at your local homebrew store or online in "wing" and "stand" varieties for $15 to $50).
- Special Occasion Caps from BottleMark
- Sanitization solution/method (caps should be sanitized before use, otherwise evil can get in the beer. See about our caps for recommendations.)
- Bottle Opener
The Procedure
- Thou shalt choose a recapping date close to thy special occasion. The closer to the event itself, the better! Four or fewer days shalt thou count. Seven days shalt thou not count. Fourteen days is right out!
- Thou shalt sanitize the custom caps. For Beer's sake, don't forget this step!
- Thou shalt uncap and recap one beer at a time. Recap swiftly, exposing the bottle as little as possible to the demon oxygen, naughty in Beer's sight.
- Thou shalt enjoy an awesomer bottle among friends on thy special occasion.
Follow these commandments and the blessings of Beer be with you!
