She will take on buying for Australia, New Zealand and some other areas for the company.
Knowles joins the Wine Society’s seven-strong team of Pierre Mansour, Sebastian Payne MW, Joanna Locke MW, Marcel Orford-Williams, Toby Morrhall, Mark Buckenham and head of buying Tim Sykes.
Sykes said: “We look forward to welcoming Sarah to our team. Her experience as a buyer and her achievement in expanding the wine range of Amathus, both wholesale and retail, plus her flair for quality, makes her an excellent addition to the team.”
The Wine Society is a mutual which sells only to its members, with no outside shareholders.
