A word of caution on synthetic corks. I purchased some, thinking they would be better than cork corks and wouldn't condemn any trees to death. The first 27, or so I used worked great. It was about 6 months later, I started to bottle and cork my next batch of wine. When I laid the bottles on their side almost all of them leaked. I had to re-position the cork on each bottle. The synthetic corks had gotten stiff over time. I've now gone back to cork corks.
