After completing all taste evaluation questions in session
2, participants were asked questions on their knowledge
of closure-related issues and their attitudes toward
different closures. On completing all test questions for
both sessions, participants were compensated $25.00.
Data analysis. All of the resulting data was analyzed
with either SPSS statistical software (version 11.5; SPSS,
Inc., Chicago, IL) or Statistica statistical software (version
6.1.264.0; StatSoft, Inc., Tulsa, OK). For participant demographic
questions and wine consumption habits, closure
knowledge, and attitudes, descriptive statistics were used
to determine the percentages of subjects in various subcategories.
For questions regarding the wine types typically
consumed and the places where the consumers typically
bought their wine, the participants were instructed to
choose all that applied, thus multiple answers were permitted.
Therefore, the percentages of each category were calculated
by dividing the answer count by the total number
of participants in the particular test.
