In 1439, a council of the Greek and Roman churches was called at Florence. According to legend, during the meeting, the Bishop of Florence proudly served his local communion wine to one of the Greek bishops who proclaimed, ‘What lovely wine! It’s xantho! (yellow)’. The Florentines, mishearing the greek adjective as santo (holy), took this as a pronouncement of quality rather than colour, and the wine has been known as vin santo ever since.
