Greene King has become the first UK brewer to be awarded Red Tractor certification for its entire beer portfolio.

The Suffolk brewer impressed Assured Food Standards - which runs the Red Tractor scheme - by using traditional brewing methods and sourcing its barley from local farmers. ASF also applauded Greene King's tradition of using water from underground chalk wells.

"Our brewers and tasters are obsessive about quality and consistency and we insist on a series of checks with suppliers," said Greene King take-home and export director Neil Jardine. "We work closely with farmers to ensure we get the best-quality ingredients and that, even when crops vary as a result of the weather, they can still deliver a consistent and top-quality bottled beer."

Greene King's y-o-y value sales rose 30% in the eight weeks to 24 January, according to Nielsen.
