But while Epic said it had sold 600,000 bottles in Sweden since March, Lion said the slimline cans were a "new format" in the Swedish market and consumers hadn't responded as favourably to the product as expected.
Liz Read, Lion's external relations director, said the firm had stopped supplying Steinlager Pure to Sweden.
Read said Systembolaget liked the Steinlager brand and the company was having discussions with its Swedish distributor regarding selling the beer in a bottle format in that country in the future.
"Regarding Epic's assertion that it has beaten Steinlager in Sweden, it hadn't occurred to us there was a battle going on and we're delighted to see another New Zealand beer brand doing well elsewhere in the world," Read said. "Internationally, Steinlager is now selling about 13.5 million bottles annually."
Epic, which brews its beer in Otahuhu, was shipping two 12-metre containers, containing around 77,000 bottles, to that country every month.
Nicholas said Epic's Swedish distributor had initially thought it would take six months to sell the first container-load of Armageddon.
"It lasted three weeks," Nicholas said. "Armageddon has struck a chord with the Swedish people and they are drinking it very well."
He said Epic had also entered the on-premise market in Sweden.
"The initial trial of 100 kegs disappeared the day they went to market with it," Nicholas said.
He said Epic had sold so well in Systembolaget's 80 premium stores that there was now an opportunity for its products to be ranged in the all of the Government monopoly's 422 liquor outlets.
