Bella also has a lower carbohydrate content than regular wine and features a nutritional panel on the bottle.
Rob Cameron, the label's winemaker and other founder, said a lot of work went into producing the low-alcohol sauvignon.
A block of vines is set aside and specially pruned during summer for the leaves to provide the grapes shade from the sun, which kept their sugar content - and the alcohol content - lower.
The grapes were harvested at night, two to three weeks earlier than they would be for regular sauvignon, which also kept the sugar content down.
Cameron said the location where the grapes for Bella were grown - in the Dashwood area of Marlborough, between the Awatere and Wairau valleys - had a microclimate that suited the production of a full-flavoured, low-alcohol wine.
"Our [growing] site is quite unique in that at lower sugar levels we do get good, ripe flavours."
Bella was proving popular with drinkers in Australia, Britain, Japan and Bulgaria, Lightbourne said.
Invivo is promoting Bella in British restaurant and bar chain Drake & Morgan. "The promotion aims to target consumers making healthy lifestyle choices in their New Year's resolutions," Lightbourne said.
He said Bella was also sold across the UK by high-end retailer Harvey Nichols.
Invivo does not own vineyards, but works with growers in Marlborough and Central Otago to source its grapes.
Cameron produces the white wines on contract facilities in Blenheim, while the reds are made at Mangawhai, north of Auckland.
