Groot Constantia is South Africa's oldest wine estate, founded in 1685 by Simon van der Stel on Table Mountain's slopes, now hemmed in by Cape Town's suburbs. For three centuries, its wines reached remarkable tables.

Napoleon ordered a case a month of Grand Constance while in exile on St Helena. Frederick the Great, King George IV and Jane Austen all drank it. Baudelaire compared it to his lover's lips.

False Bay and the mountain together trap the southeaster's moisture, giving the Constantia Valley more rainfall annually than London. Cool conditions produce wines of striking elegance, from native Pinotage to the ancient Muscat de Frontignan still behind Grand Constance today.

VoiceMap's tours walk the living vineyard, introducing each grape variety and tracing wine from shoot to barrel. They follow the Cloete family's tenure, the Phylloxera blight of 1866, and the rare terroir that made this farm famous across three continents.
