Optimum texture of ice cream and sorbet is crucial to how it's flavor is perceived in your mouth. Too hard and it will be difficult to scoop and tastebud-numbingly cold. Too warm and it will be too sweet and syrupy. For optimum flavor and mouthfeel, store ice cream between 6 and 10F (-14 and -11C). If you're storing ice cream for long periods, store it between -5 and 0F (-21 and -18C).
