Homemade lemonade, with or without mint. Blood orange juice - Waitrose does a good one. Cawston Press rhubarb and apple. San Pellegrino orangeade; I recently found a can which I think was described as "Italian style" or similar, which had more orange in than the usual version and was nicer. Any of Cornish Orchards' juices or fizzy drinks, though I don't know how available they are outside Cornwall.
