Our 18.5mm high top glass cork is our first ever glass based cork. We have found that this cork works with our range of polo bottles. However we recomend to all of our customers to test the corks and bottle with their products first before commiting to larger order.


The cork is manufactured by Vinolok corks and is of the highest quality. They have provided us with some handy tips to see if this cork works for your bottle.


  1. Make sure the inner neck diameter of your bottle matches the size of the cork. In this case the inner meaurement should be 18.5mm
  2. Test the corks on several bottles! The corks should be easily inserted and removed by hand.
  3. Apply a shaking test. Lift the bottle up by the cork only and give it a little shake. The cork should not fall out of the bottle.
  4. Lastly do the leak test. Fill the bottle and leave laying on it's side for 5 minutes to ensure there are no leaks.


This cork will suit any premium spirit such as gin, whisky, rum etc. This really is a special cork so if you are looking for something special for your product, look no further.
