Bottle caps come in tons of colors and designs. They also come with both oxygen absorbing seals and regular seals. Stick to silver or black if you plan on entering homebrew competitions. Make sure to leave the caps mark free as well.
Are oxygen absorbing caps a savior or a waste of money? Oxygen absorbing caps are touted as being able to absorb extra oxygen in your brew once capped. Apparently, the technology starts as soon as they get wet so sanitizing activates the caps. I’ve tried both with no difference and have seen many people claim the same. Of course, they only cost about one to two dollars more so I buy them anyway. I don’t mind spending a few bucks on the off-chance they save my beer from oxidation.
Saving bottle caps can come in handy for collecting, crafts or even currency in the apocalypse. A twist top comes off without our trusty bottle opener but as homebrewers we care about pop toppers. Use a quarter placed on top and a wide-holed opener to prevent damage to the caps. You might have to pry on several sides but it will come off in perfect condition.
The bottle caps are nice because they have a small footprint so you can collect many of them. They can also be recapped on bottles if you enjoy saving the whole shebang. Trust me on the space issues as I’ve completely run out of room for bottles.
Bottle caps make some absolutely badass art. My favorite is a coffee table covered in caps with resin poured on top. Country or state shaped wood pieces with bottle cap slots are really cool for representing that region. Finally, if you are really artsy you can make whole murals out of bottle caps. They look amazing but I’m definitely not capable of making one.
A metal handled capper or bench capper are your best options if you plan on bottling a lot. They accept crown caps that fit nearly all 12oz and 22oz bombers. I use the universal capper for all my capping. Here’s my review on it.
Swing top bottles are your alternative to regular capping. They consist of a bottle, metal hinge, and a rubber stopper. I think of the green Grolsch bottles when I hear flip top. Don’t use them as the green bottles won’t protect your beer! Some homebrew stores sell them in a 750ml version if you want to try them. I really don’t like flip tops but appreciate their bottle bomb prevention.

Now go out there and brew something and don’t forget to admire that little metal hat next time you grab a cold one!
