Majestic consolidated its reputation for having the best-trained staff in drinks retailing by picking up eight awards at the WSET graduation ceremony in London's Guildhall on Monday night.
The chain was by far the biggest winner on the night, which was attended by hundreds of guests from around the world who came to congratulate this year's prizewinners and Diploma graduates.
Majestic retail director Greg Jones said : "The fact that we received so many awards is a testament to our recruitment and our product training programme."
Waitrose, Oddbins and Jeroboams were also represented among the winners.
This year's top Diploma student was Anne McHale of Berry Bros & Rudd, who follows in the footsteps of Jancis Robinson MW and Arabella Woodrow MW by winning the Vintners' Cup.
Chief executive Ian Harris said that 21,420 people took a WSET qualification in 2006-07 - a 20 per cent increase on the previous year. 21,420 students took a WSET course in 2006/7.
