I bottled my wine bottles with a Portuguese floor corker, but the dimple is still in the agglomerated cork after a year.

I was told to:

  1. Wait three weeks with the bottle upright.
  2. Store a year with the bottle upside down to keep the cork wet.

What measures can I take to minimize that dimple? Why doesn't it show up on commercial bottles?

I'm just hearing about potentially hacking in a broader surface with a shaft collar at the end of the aluminum rod that presses in the cork.


Using a coin reasonably smaller than the 18.5mm diameter to reduce the pressure and spread out the force over a larger area is another hack.
