so the modified wine stopped, all you did was remove the metal thing inside and cut a decent sized hole on the bottom? are there any uses for the metal thing inside the wine stopper?
Other way around I figured out. Cut the tip off, then push the metal cap out from the hole you created. There is also a nylon o-ring in the stopper to maintain rigidity, you'll want to leave that in there as it helps to hold the tubing in place.
I saved my metal cap thinking I could use it for something, tossed it a few weeks ago.
I got a four pack, Purple, Orange, Green & Blue (unfortunately, you're not able to pick colors), so I did the Purple first as a test (least favorite color). It worked the first time, so I am stuck with Purple for the time being.
As
@Tweak stated, no noticeable taste. Even if there was a slight taste, the tradeoff would be worth it to me.
Sorry for the threadjack. Kind of has to do with carbed GonGs though.
