Grwpiau o fusnesau yw clystyrau bwyd, sydd â’r un diddordeb mewn cydweithio er lles pawb. Eu nod yw sicrhau nad yw busnesau’n gweithio ar eu pennau eu hunain, yn enwedig busnesau bach a chanolig, a’u cysylltu â systemau arloesol.  Mae dros 450 o gwmnïau yng Nghlystyrau Cymru, ac maen nhw’n creu busnes drwy annog mwy o gydweithio yn y sector.
Food clusters are groups of businesses with a common interest working together for the benefit of all. They aim to remove the isolation of firms, especially SMEs and connecting them to innovative systems.  There are over 450 companies involved in the Welsh Clusters, generating business through increasing collaboration within the sector.
