Throw in an idyllic setting among the Hunter Valley grape vines, a relaxed, laid back feel and you've got the annual Shakespeare in the Vines event at Calais Estate winery on Saturday.

Essential Theatre artistic directors Amanda LaBonte and Sophie Lampel are very proud to be celebrating their 18th summer of Shakespeare in the Vines - a tour of Shakespeare's classics to some of Australia's most spectacular wineries and gardens.

Tempted by the prophecies of three mysterious witches, and encouraged by his power hungry wife, Macbeth will do anything to be King.

He is quickly lead into a nightmarish world of evil and deceit as he tries to murder his way to the throne of Scotland.

Shakespeare's rousing tragedy is filled with ferocious battles, supernatural horrors, stunning language, and some of the Bard's most vivid characters.

From a time where people are hooked on Game of Thrones and Black Mirror, where political ambition drives decisions at any cost, Essential Theatre take it back to where it all began with this iconic character. Macbeth promises to be raw, edgy and entertaining.

The Shakespeare in the Vines program has grown from strength to strength ensuring the longevity of this ambitious and entrepreneurial Victorian theatre company.
