Good Morning Gentle Readers,
TWC doesn't like fake corks or screwcaps on principle. It doesn't sway me one inch that natural cork has shortcomings. If God intended wine bottles to be plugged with synthetic corks he would have given us synthetic trees. Oh, I'll get email about that.
One shortcoming of synthetic cork is that sleek, minimally invasive, high dollar corkscrews, like the Rabbit for instance, act as if the cork is made of paraffin. The corkscrew worm, a technical term, slides right back out like a hot knife through butter, leaving the bottle still corked. Then you have get out the fat boy. No, not Willie Nelson's fat boy, you'll still be able to get at the wine, you'll just need the corkscrew that looks like a fence post auger.
On a slightly different note I have a client who is developing a process to make a better synthetic cork. It's proprietary at the moment so I don't know much about it except that he loves wine and he's in the plastics business. That ought to work.

Oh, and about Willie's fat boys.....
