Charles Metcalfe and Kathryn McWhirter wrote their first book on Portuguese wines over 20 years ago.

Charles is one of the most spontaneous and amusing wine critics in Britain, and a well-known face on British television, having been part of the ITV This Morning team for 12 years. He was a co-founder of WINE International magazine, and is co-chairman of the International WINE Challenge, the world’s biggest wine competition. Before turning to wine, he was a professional singer. He spends much of his time entertaining all sorts of audiences with wine-related topics, particularly, at present, the wines of Portugal.

Kathryn was drinks correspondent for the Independent on Sunday for nine years, sometimes also writing about food. She wrote and edited the Which? Wine Guide and Good Wine Bar Guide for the Consumers’ Association, as well as wine list reviews for the Good Food Guide, and was editor of Wine & Spirit magazine.

Together Charles and Kathryn have written books about wine and matching wine with food for Sainsbury’s, Tesco and Marks & Spencer, as well as other publishers.
