lt the EZ cap bottle has a special closure, more commonly known as a “grolsch” Style closure, which is a wire bale which swings a ceramic cap and rubber gasket upward and over the neck to seal the bottle. The most obvious advantage to this Style of bottle is that it is easily resealable. These great bottles are smooth sided, making labeling very easy! they are thicker and stronger than regular bottles. One interesting point is that since the tops are reusable, they are more environmentally friendly. These traditionally styled bottles call attention to the craftsmanship put into the contents. Perfect for showcasing your special beers.
