Giles Fraser explores the place of wine in some religious traditions, as the blood of Christ, the nectar of the Greek Gods or Persian poets, to something forbidden or proscribed.

We start on a balmy evening in Napa Valley, with a sea breeze blowing through the vines at Marinda Kruger's vineyard. For her, life as a viticulturalist has an intimate connection to her faith.

Gisela H Kreglinger, theologian from a wine-making family, Catholic Priest, Father Marc Lyden-Smith and Muhammad Ali Mojaradi, translator of the Persian Sufi poets under the moniker Persian Poetics on social media, join Giles to consider the pleasures and prohibition of wine.

Many scriptures and religious poetry are awash with the stuff. Wine flows in heaven, goblets elicit a kind of spiritual ecstasy and Noah's first act after the flood? To plant a vineyard. What has been wine's significance in different religious traditions, and what does our relationship to it reveal about our earthly selves?
