The Buyer | Helen McGinn on why she had to write a supermarket wine guide

“I’m asked for wine recommendations every single day. When the idea of this book came along, I knew I had to do it.” That’s how Helen McGinn describes her new book - The Supermarket Wine Guide - that promise to be a definitive guide for the best quality and value wines up to £20 available on a UK high street. Buying wines is how she first made her way in wine, as a wine buyer for Tesco, but recommending them helped her move into her now successful broadcast and writing career - it all started with The Knackered Mother’s Wine Guide way back in 2013. Here she explains what you can expect from her supermarket wine guide when it is published in May.
