What is a Bar Top Closure?

Bar Top BottleBar top closures or (cork stoppers) combine a cork shank with a wider cap that is made to seal glass bottles made for liquors, spirits and fortified wines, as well as some vinegars and oils. The cork shank is designed to fit snugly in a glass bottle to create a proper seal while the cap sits on top of the bottle neck for easy removal.

Designed for repeated use, these stoppers maintain product freshness and protect bottle contents from contamination. For these reasons, finding the right fit for your bar top cap can be a critical factor in packaging your special spirit or condiment. In fact, the right closure can be a critical part of the overall packaging aesthetic.

To find a proper fitting bar top cork stopper, you want to make sure that the shank (or cork) is wide enough to create a tight seal within the bottle.

Parts of a Bar Top Closure

A bar top closure, or cork stopper, includes a cap and a shank. The cap can be made of plastic, aluminum, wood or the same finish as the shank. The shank can be natural or synthetic cork.

The two dimensions following the name of this closure are the CAP diameter x SHANK diameter (in mm). You need to find the shank diameter measurement to find a compatible bar top closure.

Finding Your Fit

As a general rule, you want a shank (cork) that is 1 mm larger in diameter than the bottle neck width to ensure that your top fits tightly.
