Although its cask range was only launched three months ago, the company's 3.8% abv Fuggles Bitter - described as an easy-drinking bitter with floral aromas - and the 4.2% abv Goldings Ale - a golden ale with delicate fruit flavours - are now available in 500ml bottles. The beers, which have a retail price of £1.69 and £1.79 respectively, are already being distributed to the off-trade and wholesalers.
MD Paul Simpson said: "Our aim is to increase consumers' knowledge of our beers and develop their understanding of what goes into a great pint."
Two additional products, called Challenger Special and XB, will be available in bottles from the middle of next month.
The launch coincides with this year's annual Great British Beer Festival, which opens the doors at its Earls Court venue from 1 to 5 August.
