Hancocks was described in court as the instigator of the plot
A brewery boss who was jailed for plotting to contaminate a rival firm's products has had an appeal to reduce his sentence dismissed.
Michael Hancocks, the managing director of Birmingham-based Aston Manor Brewery, was jailed for 18 months in August for concocting a plot to contaminate the production line of Hereford-based cider-maker HP Bulmer.
Although the scheme never got off the ground, the 63-year-old from Hafod Road in Hereford was jailed for conspiracy to defraud.
The Appeal Court in London dismissed his appeal against the length of his sentence on Thursday.
Hancocks had been described in court as the "prime mover" in a plan to pour yeast-based contaminants into Bulmer's production line.
His firm, Birmingham-based Aston Manor Brewery, was in direct competition with Bulmer's in the cider market.
