The brand, which was initially launched in London last year, will see its official England off-trade launch this year following strong sales through stores in London and Scotland.
A marketing campaign this spring will include a TV advert - the first in a series for the year - promoting the concept of Magners served over ice.
Marketing director Maurice Breen said: “Consumers have responded very positively to our unique product served over ice.”
Breen said off-trade sales in the UK had grown quicker than expected, but the company had no plans for new cider variants.
Magners will be launching a 750ml crown-cap bottle in April.
