Eden Pale Ale is a 4.8% ABV golden beer made with British malts and Continental and New World hops. It is flavoured with saffron and alecost, a herb that was used in beers in the 16th century, and grown at the Eden Project.
The brew is part of a deal that will give St Austell pouring rights at the tourist attraction.
James Staughton, managing director of St Austell Brewery said: “We are delighted to be working with Eden on this exciting collaboration. It seems a very natural partnership between such close neighbours.
“Eden Pale Ale will be an excellent addition to our range in the exciting new craft beer market and we look forward to developing a selection of Eden-inspired beers using ingredients grown just down the road at the famous attraction."
