Greene King has become the first brewer in the UK to be awarded the Red Tractor certification for all its beers - an independent mark that guarantees the quality and origin of ingredients.

The Red Tractor scheme, which also guarantees certain ethical production methods of food and drink, now appears on over £7.5bn worth of food and drink in the UK.

David Clarke, chief executive of Assured Food Standards, which runs the Red Tractor scheme, said: "Congratulations to Greene King on being the first brewers to gain Red Tractor across all their beers. It is something of which everyone in the company can be extremely proud. 

"They have an impressive set-up based on traditional brewing methods, using top quality local ingredients and with excellent controls throughout the supply chain. It offers them the opportunity to communicate an extremely positive and relevant message to consumers, which we are only too pleased to endorse."

Steve Magnall, Greene King brewing and distribution director, said: "Our brewers and tasters are obsessive about quality and consistency and, in addition to rigorous controls and processes in the brewery, we insist on a series of checks with suppliers."
