BOTTLE CAPS - AMERICAN FLAG

Bottle Caps - American Flag Oxygen Absorbing

• Commercial quality beer bottle caps to keep your brew safe and sound from bottling day until you're ready to enjoy it.
• You will get a good firm seal that will last through transport, gift giving, and storage with these American flag bottle caps. These bottle caps crimp down onto the beer bottle and make a firm seal.
• They don’t rust or leak and they contain an Oxygen absorbing agent in the liner, which means you won’t get any unwanted oxidation. A good value for a great product.
• 26 mm diameter caps fit American bottles. Some imported bottles and some sparkling wine bottles use a 29 mm cap instead. We recommend test fitting prior to filling if you're re-using an imported bottle.

Important to Note

• It is recommended that you only sanitize as many caps as you'll require at the time of bottling. The oxygen-absorbing agent is activated when the cap gets wet. If wet caps are saved for later use, they'll still function as a normal cap, but the oxygen absorbing agent may be depleted.

Other Notes

• Dedicated brewers will know that beer exposure to oxygen should only occur before fermentation and not after
• It's the same with food - oxygen will damage food so that's why many foods are packaged in plastic with 'oxygen scavenging' features - look at potato chips, the bags they come in are filled with nitrogen!
• If you are trying to minimize the amount of oxygen in your bottled beer, mead or wine, you may want to consider using oxygen absorbing caps.
• The bottling process can add unwanted oxygen into the beer if you are not careful and too rough with your wort.
• To remediate this you can do things like being careful with your pouring into the bottle and using a bottling wand.
• If you want to do more than that, the bottle caps can help remove the oxygen that sits above the surface of the beer and between the bottle cap.
• If you are looking to cellar or age your beer, these caps could help you achieve your goal.
