Brewer Greene King has launched a premium version of its India Pale Ale to offer drinkers a more robust beer.

Export Strength IPA, which is packaged in 500ml bottles rather than the standard 660ml size, contains 5% abv alcohol compared with the original's 3.6% abv.

It will be priced between £1.60 and £1.85.

Managing director Justin Adams said: "It contains a high concentration of hops, which gives it a fresh, aromatic character, so that you can drink it on its own or as an accompaniment to a meal."

India Pale Ale dates back to the 1800s when it was first brewed for export to India.
