EZ Cap bottles are a great alternative to traditional beer bottles for your beer. The grolsch-style swing caps create an airtight seal which locks carbonation in and keeps beer fresh. Also, fresh crown caps are not required every time, though the gaskets may need to be changed occasionally. EZ Cap bottles are also great for kombucha! These EZ cap bottles are clear and can be used to bottle just about anything. With two convenient sizes available, you can start out small or go big right away!
