“If music be the food of love,” says Duke Orsino in Twelfth Night, “play on.” And play on they do, with food and wine. For the 11th year, Geelong’s Essential Theatre brings the Bard’s plays to wineries in Australia and New Zealand over summer. This year, Twelfth Night tours two countries in January and February following a premiere performance in Geelong the week before Christmas. The romantic comedy comes to SA twice, to Seppeltsfield in the Barossa Valley on January 26 and Coriole in McLaren Vale on January 27, and returns on February 15 and 16 to Sevenhill Cellars in the Clare Valley and Johnstone Oakbank in the Adelaide Hills on February 17.
