@wesheadley… “Will all wine be in screw-cap bottles in 20-30 years?”
You know… good question. Yes. I have a wine cellar with a few hundred bottles of red wine. I am seeing better wine having screw caps. At first I was very skeptical… the long tradition… the ability of oxygen to slowly age the wine. The technology to construct a cork. But the amount of tannins in good quality wine has been coming down over the years so that wine sold today is to be consumed in the next few years as opposed to cellared for a decade or two. I don’t see that trend ending. More and more I see real corks only used in top tier wines for connoisseurs.
