Wells and Young's Brewery has teamed up with The Royal Botanic Gardens at Kew to launch a new beer in the UK.

Young's Kew Gold is a beer inspired by hops grown at Kew Gardens, with a percentage of each bottle sale being donated to the work that RBG Kew undertakes to restore habitats and save endangered plant species.

John Lonsdale, head of public programmes and curatorial support, said: "Kew is working to increase and share our acquired knowledge of plants, their potential uses and the importance that they have on surrounding biodiversity. As Kew approaches its 250th Anniversary in 2009, we are delighted to be working with our longstanding supporters, Wells and Young's."

The new product is a light, golden ale that is bottle conditioned which means that it is the closest beer to cask ale that can be got in a bottle.

Young's Kew Gold is part of the new range of Young's bottle conditioned beers which also include Young's Bitter and Young's Special London Ale.
