What’s the deal with screwcaps?
Screwcaps, actually known as Stelvins in the trade, are quickly replacing natural cork in many wine bottles. Natural corks are, well, naturally irregular. Some produce great seals, others less so, resulting in different bottles of the same wine behaving differently as they age. In addition, natural corks are prone to becoming corked: a chemical reaction, which can happen when bleaching corks, that imparts wines with a taint known as TCA. Screwcaps are perfectly uniform and provide a perfect seal for your wine, avoiding the issues that might arise with cork-finished bottles. Many high-end wines now use screwcaps, and they are the wave of the future.
