Visiting South Australia often entails visiting lots of wineries. We stopped at Sevenhill winery in the Clare Valley, which is owned by the Jesuits and which produces all of the sacramental wine for the Catholic church of Australia. I learned some things about communion wine that I never realized before, making me curious about Lutheran and other churches’ practices.
Sevenhill sacramental wine, I was told, is made according to the exacting standards and requirements of canon law. So its characteristics will apply to most wine used in the Roman Catholic Church.
