The company was attending CRS with the promise that it had 10,000 heating units to give away to the first retailers to sign up to the concept which has been a success in Japan.
Rashad Hussain, head of marketing at Essex-based Hot Shot, said: "We have had a tremendous response at the show, not only from independent retailers but also from buyers representing multiple retailers. There has even been an inquiry from a French visitor."
The range of six drinks, which are manufactured in Taiwan, include black and white tea and coffee variants and hot chocolate. The cans are warmed in a custom-built heating unit. Rashad said the cost to the retailer worked out at 48p a can plus VAT with an rsp of 99p.
