About the event

Join Professor Tim Spector, co-founder of ZOE and leading researcher in nutrition and health, with Spencer Hyman for an evening introducing Tim’s new book, Ferment. Focussing on the science of fermentation, this session will take a deep dive into polyphenols, macronutrients, and micronutrients: what they are, why they matter for health, and how they show up in foods such as chocolate. Taste along with some chocolates as you learn about the role of fermentation in chocolate in developing both the flavour and nutritional value of chocolate. You’ll also hear about why chocolate is a ‘health food’ and how you can use your sense of flavour to help move away from scoffing ultra-processed foods.

The tasting will run from 18:30-20:00 on Friday 10 October, 2025 at the Fidelio Cafe, Farringdon. Please note: this event will take place before the 2025 Cocoa Runners Craft Chocolate Fair, which takes place on Saturday 11th and Sunday 12th October, 2025.

About the Cocoa Runners Craft Chocolate Fair 2025

For the third year running, Cocoa Runners are hosting their ever-popular Craft Chocolate Fair on the 11th and 12th October, 2025. Meet craft chocolate makers from across the UK and beyond at the indoor market, and join a series of talks, tastings and experiences in our beautiful tasting room. The events will take place at the Fidelio Cafe and Concert Venue in Farringdon, London from 10am-5pm.

Following the success of the past two Craft Chocolate Fairs and previous sold-out events at Canopy Market, this year’s Fair will see even more bean-to-bar chocolate makers bringing their chocolate to London, including Chocolarder, Friis Holm, Pump Street, Choco Del Sol, Bare Bones, Neary Nogs, Fjak and more.

Ticketed talks and tastings will take place across both days. Due to the popularity of previous years, we’ve now introduced free, pre-bookable tickets; they will guarantee you entry to the fair during your time slot without queuing.
