The Rum roller brings three elements, zero dilution, chilling and motion, the rum drinking experience. The stainless steel chilling balls are essential as aged rum should not be served with traditional ice because the ice will slowly bruise the aged rum. Bruising will result in an inconsistent taste from beginning to end, as well as loss of aroma and flavour. A simple wrist motion rolls each of the chilling balls around the bottom. The outward curve prevents them from rolling out while sipping. The glass profile flares out at the top to help release aromas while drinking. Tongs are included for safe and clean handling of chilling balls. The Rumroller's chilling & motion, with zero dilution, will take your enjoyment of drinking rum experience to the next level.
