Spar has almost completed an overhaul of its own-label range as it looks to boost its share of sales in store.
Four lines have been added to its relaunched soft drinks range and the recipes and taste have been improved on 11 lines.
Spar soft drinks were worth £20m in retail stores and offered retailers higher margins than big brands, said Spar UK.
The retailer is currently reviewing its range of own-label household products, completing a benchmarking exercise across all own label categories begun in 2009.
Its attentions will then turn to fresh and grocery.
Spar has also launched price-marked packs across most of its frozen food to create a consistent value message.
