BOTTLE CAPS - COLD ACTIVATED

Bottle Caps - Cold Activated Oxygen Absorbing

• Cold Activated 26 mm crown bottle caps.
• These caps will turn blue and display a "Ready To Drink" message when they reach a cold enough temperature 5° Celsius and below.
• These caps also have an oxygen absorbing liner that will absorb any oxygen left in the head space.
• This helps reduce the oxidation that happens during the bottling process, keeps your home brewed beer tasting fresher, and can extend it's shelf life.

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.
