According to a recently released ongoing study, ACNielsen, which monitors primarily chain groceries/drug/liquor retailers, reports that screwcap closures continue to grow...and sell.
ACNielsen estimated that in their segment of retail screwcaps represent $200 million in sales, with 4% of market share---but with a growth of 50% since March 2006 alone!
ACN also cited a growth in number of wines under screwcap at 66% in 2006, with 552 total (213 domestic, 339 imports).
Note: ACNielsen reports on retail sales for essentially chain grocery/drug retailers, so it represents only a portion of the market. Few indie retailers, very little of the Northeastern non-chain markets, and no restaurant/on-premises activity, etc.
