A SURVEY CONDUCTED BY THE CALIFORNIA WINE CLUB
shows that most consumers view wines with screw caps to be the same quality as wines with corks.
More than 50% of responders viewed screw caps as having the same quality, while 35% believed they were less quality. Only 2% of respondents believed screw caps were of higher quality, while 10% said they did not drink wines with screw caps.
At the same time, 65% of respondents said they would not be disappointed if the wine they ordered at a restaurant arrived in a screw cap. The responders were split on whether or not restaurant wine lists should specify which bottles have a screw cap, with 50.5% saying yes, and 49.5% saying no.
The California Wine Club was started in 1990 by Bruce and Pam Boring, and is one of the largest wine clubs in the country.
