As opposed to traditional ice cubes, the Avanti® Granite Whisky Pucks do not melt, ensuring your whisky or favourite spirit remains chilled without diluting or compromising the flavour. Cut from natural granite, the shape and size are perfect for whisky tumbler glasses allowing the discs to sit on the bottom of the glass whilst at the same time cooling. They are reusable, non-porous, odourless and do not impart flavour. They offer a perfectly chilled drink from the first sip to the last!
