Waitrose has recruited a buyer for German, Eastern European, North American and English wines.
Ken Mackay MW - the youngest current Master of Wine - will join the BWS department on March 10 from wholesale distributor Willoughby's.
Buying manager Justin Howard-Sneyd MW will give up direct buying responsibilities and will focus entirely on running the team.
From the summer, Mackay will also be responsible for buying New Zealand wines. Buyer Andrew Shaw will take on the Rhône and the south of France.
Waitrose has also recruited Anne Jones as information manager. She will be responsible for producing the Waitrose wine list, co-ordinating in-store publications and providing information for the website.
Waitrose will run a month-long French Wine Showcase from March 26. It will feature 48 wines including Taittinger Rosé NV (£31.99 reduced from £38.99), Champteloup Vieux Vauvert 2006/07 (£4.79 down from £5.99), Domaine de Buganay Provence Rosé (£6.39 from £7.99) and Domaine des Eyssards Bergerac Rouge 2005 (£4.49 from £5.99).
Waitrose has increased its range of wines in 25cl and 50cl bottles by more than 50 per cent, partly by rolling out its eight-strong Vin à Deux range.
