Venison is the name given to any of the species of deer sold as meat in the UK. The lean, red meat is low in fat and full of flavour and has become popular and widely available. Deer can be classified as wild deer, park deer (reared in herds that roam parklands) or farmed deer (rearing varies from free-range to intensive). The most common varieties of deer in the UK are red, fallow and roe.
