Fullers will launch in the U.K. its first permanent cask beer in more than 20 years with the addition of Discovery to its beer portfolio.

It will be sold alongside sister brands London Pride and ESB in all Fullers pubs and bars beginning this month, as well as in free-trade pubs that currently stock Fullers.

The beer, which Fullers hopes will attract new drinkers to the category, will also be available in supermarkets in 500ml bottles.
