The cider producer and apple grower has been processing more than 90 per cent of the UK's annual blackcurrant harvest since 1998.
The blackcurrants are processed for the makers of the popular cordial Ribena as part of a long-running partnership between Thatchers and Ribena, which is now owned by Lucozade Ribena Suntory.
Every year, Thatchers employs an additional 20 people during the harvest season, processing 10-12,000 tonnes of blackcurrants and 450 tonnes of apples per day during the autumn. Every July and August, harvesters drive up and down the 1,619 hectares of Ribena's blackcurrant bushes. The berries are then hauled to Thatchers where they are processed and transported to Ribena's headquarters in Coleford, Forest of Dean.
After his visit last month (August 2015), John Penrose MP said: "Ribena isn't just a part of everyone's childhood; it's a global business with sales all round the world - just like Thatchers Cider in fact."
Thatchers managing director Martin Thatcher said: "We were delighted in showing John Penrose, our local MP around today."
