The four-strong range is all carbonated and made from an apple juice base.
Thor Original has a straight, dry, apple flavour; Thor Fire has added ginger; Thor Ice has added mint and Thor Thunder added caffeine.
“When it comes to drinking out, we found that many of the soft drinks on offer were uninspiring and to be endured rather than enjoyed,” said Alistair Scahill, founder of Thor Drinks.
“While a lot of the alcoholic options are given sophisticated profiles, the soft drinks on offer didn’t seem to match this. We wanted to redress the balance with an exciting and premium alternative to alcohol.
“We have used a lot of complex flavours to create Thor drinks, making them much more appealing and enjoyable to drink.”
The brand is aimed at 24 to 40-year-olds with a recommended selling price of £3 per bottle. There are plans for limited editions and seasonal flavours.
