This week, we bring you a very special live Wednesday edition of Beer Sessions Radio featuring Tristram Stuart, an international award-winning author, speaker, campaigner and expert on the environmental and social impacts of food waste. His books have been described as "a genuinely revelatory contribution to the history of human ideas” (The Times) and his TED talk has been watched over a million times. National Geographic featured Tristram's food waste activism on the cover of their May 2016 issue. The environmental campaigning organization he founded, Feedback, has spread its work into dozens of countries worldwide to change society's attitude towards wasting food.

He is also the founder of Toast Ale, a beer launched in the UK in 2016 that is made using fresh, surplus bread.
