The Food Chain

Taste, it turns out, is not a matter of opinion. Scientists have discovered that your perception of taste is informed by your genetics.

When we eat or drink something, we may be having an entirely different experience to the person we’re sharing a meal with, or the chef who has prepared it, or the critic who has recommended it.

In this programme Ruth Alexander explores her likes and dislikes and how they might be informed by biology.

Ruth meets Laura Kent of the Yorkshire Wine School in the UK who helps her learn about her sensitivity to acidic and bitter flavours. Ruth speaks to Anne Fadiman, writer and Professor of creative writing at Yale University in the US, who dislikes wine, despite her wine critic father loving it. Danielle Reed, Chief Science Officer at the Monell Chemical Senses Center in Philadelphia, US, explains the science. Tim Hanni, Master of Wine, and author of ‘Why You Like The Wine You Like’ argues that the wine industry is not paying enough attention to individual tastes. Where does this new science leave wine competitions? David Kermode, judge at the IWSC, International Wine and Spirits Competition, makes the case for the experts.

The business of food tours

Food tours are becoming one of the fastest-growing parts of the travel industry, with tourists increasingly choosing to explore cities and cultures through what they eat.

In this episode, Ruth Alexander explores the global rise of guided food experiences and the people building businesses around them.

In Manchester, food tour guide Julia Fairburn takes Ruth through some of the city’s best-known food spots, explaining how successful tours combine local history, storytelling and carefully paced eating experiences designed to leave visitors with lasting memories.

Eric Wolf, founder and executive director of the World Food Travel Association in Valencia, Spain, explains how food tourism has expanded worldwide into a multi-billion-dollar industry, as travellers increasingly seek authentic and immersive culinary experiences.

We also hear from Judith von Prockel, who began creating holidays centred around food experiences more than two decades ago, long before culinary tourism became mainstream. She reflects on how attitudes towards food travel have changed and why people are increasingly planning trips around what they want to eat.

And in Malaysia, Pauline Lee from Simply Enak describes the work involved in creating memorable food tours in a growing and increasingly competitive market, where guides must balance logistics, hospitality and cultural storytelling alongside the food itself.

From hidden local gems to global tourism trends, we explore why food tours have become big business — and what travellers are really looking for when they book them.
