Spar has declared its debut wine festival a success after sales rose 8.3% during the six-week promotion.

South African wines were the biggest hit, with sales up 237% between 22 April and 2 June. Promotions included 25% off 35 SKUs.

"We took special care to choose ranges that would fit in with consumer trends and activities South African wines to tie in with the World Cup and wines from France to give a balance of styles and depth of choice," said Spar's wine buying director, Chris Lewis. "We plan to roll the festival out again at a ­similar time next year."
