A survey of 1,000 regular wine drinkers in late 2006 found that three-quarters of respondents thought screwcaps were acceptable, compared to 64 per cent in 2006.
A "significant minority" of natural cork fans did not see screwcap as part of the romance of wine, according to the report.
Strategy and brand consultancy Wine Intelligence also says that store check data collected in January 2007 and April 2005 shows a significant increase in the number of products sealed with screwcap in the UK market.
"Over the past four years, we have seen an unprecedented shift in UK consumer behaviour and attitudes to wine bottle closures," Wine Intelligence operating director Richard Halstead said.
"The evidence presented in this report shows the extent to which screwcaps now play a part in sealing wine sold in the UK, and the levels of resistance still apparent in the market to this new style of closure."
