John Schreiner’s passion for wine has caused him to lead a double life. The Saskatchewan native had a 40-year career as a business writer with the Financial Post. But a tour of the Robert Mondavi winery in Napa in 1974, conducted by the legendary winemaker Zelma Long, sparked an intense interest in wine. Since then, he has developed a parallel career as a wine writer, starting with regular columns in the Financial Post and Vancouver Magazine.

His major focus has been on writing books about wine. The first was The World of Canadian Wines, published in 1984. The third edition of The Wineries of British Columbia was released in 2008 and the fourth edition of John Schreiner’s Okanagan Wine Tour Guide will be released in the spring of 2012. The companion book, John Schreiner's BC Coastal Wine Tour Guide, as released in May 2011. In total he has sold over 50,000 copies of wine related books.

One of John’s previous books, British Columbia Wine Country, won a World Gourmand award for photography, a gold medal in the 2004 Vancouver Magazine Awards, and two silver medals in the 2004 Cuisine Canada competition. A member of numerous wine societies and an award-winning home vintner, Schreiner has toured wineries in virtually all of the world's major wine regions. He is a graduate of the German Wine Academy and has judged in wine competitions in Canada and abroad. He is the former chair of the selection committee of the Vancouver Playhouse International Wine Festival.

His articles on wine appear in Wine Access, in Savour magazine, on PlanitBC.com, in several community papers and on his blog, http://johnschreiner.blogspot.com. He also has a weekly wine commentary on CKNW radio in Vancouver.
