Atkin writes for a number of publications, including: a monthly column in Woman and Home, the Wine List Inspector for The Economist's Intelligent Life and Wine Editor at Large at Off Licence News. He also regularly contributes to: The World of Fine Wines, Imbibe, and Australian Gourmet Traveller Wine. On television, he appears regularly on BBC One's Saturday Kitchen as one of the programme's wine experts. In September 2012, Atkin appeared on a BBC One Inside Out programme about the English wine industry. On radio, he does interviews on Radio 4's Today Programme and Eddie Mair's PM show, among others.
Atkin judges several international wine competitions: he is as co-chairman of the International Wine Challenge and chairman of the New Wave Spain Awards, the South African Top 100 and the Vins de Pays Top 100. He speaks and teaches at wine conferences, wine associations, consumer, corporate and charity events.
Atkin is one of the Three Wine Men (together with Olly Smith and Oz Clarke), which holds events around the UK to bring wine consumers together with wine and food retailers and producers. Atkin's  have been published in The Guardian, The Telegraph and The World of Fine Wines and exhibited in Beirut, Gigondas and London.
Previously, Atkin published a column in The Observer, Observer Food Monthly, and his interviews were published in The Guardian and The Observer (such as this account of the wine interests of David Ginola or this interview with Gérard Depardieu).
In early 2010, Atkin's weekly column in The Observer was reduced to two or three wine recommendations and he moved to The Times the following month, where he had a weekly column for a year. Atkin commented: "I am sad that The Observer has decided to reduce the scope of its wine coverage at a time when people need reliable advice more than ever. I will miss the challenge of writing what was (I hope) an engaging, informed and entertaining piece each week". In protest, a Facebook group called "Save the Wine Column" was formed and quickly amassed considerable support. At the time several newspapers had slashed their wine columns, for example The Sunday Times (Joanna Simon), The Independent on Sunday (Richard Ehrlich), and The Wall Street Journal (Dorothy Gaiter and John Brecher).
Atkin holds a BA from Durham University in Modern Languages and a master's degree from the London School of Economics in European Studies. He became a Master of Wine in 2001, winning the Robert Mondavi Award for the best theory examination. He is a Caballero del Vino, a Chevalier du Tastevin and a member of the Ordre du Bontemps.
