I love drinking wine. I've lived in Italy for 3 years and, now, the German wine region for 3 years. What is the truth about wine corks? Wine comes in bottles with various tops, but is one top better for preserving wine quality? I am traditionally programmed to thing that screw-top wine is cheap, but is a screw-top bad for quality? Is it perhaps simply a marketing perception? We all believe screw-top wine is cheap; therefore, wine makers only put screw-tops on their cheap wine.
