This 25.5mm by 34mm composite cork is specifically designed for corking Belgian Ales. This fits the Duval, Unibroue, and most American craft brew Belgian ale style bottles that are sealed with a cork.
This can be inserted in a Belgian style ale bottle with a floor corker only (a hand corker is not strong enough). You need to press down only part way when corking with a floor corker to sucessfully use these corks. Some brewers put a #6.5 stopper on the pushing shaft of their floor corker, so it does not go down all the way, preventing you from fully inserting this cork into a Belgian ale bottle (it is supposed to be inserted half way).
See the required wire tie downs when you put this in your cart. Wire tie downs can be secured with needlenose pliers. Pack of 30.
