Leith Distillery says:

'Perpetuity is our infinite blend Scotch whisky. With the launch of Batch I, we began a process that will go on, we hope, in perpetuity. Inspired by the concept of an infinity bottle, we found some exemplary casks of Single Grain and Single Malt Scotch whisky, and carefully blended them together. We will then add further casks of different whisky into the blend, before bottling half of that for future batches. This process will be repeated again, and again, and again, creating an increasingly complex blend assembled from multiple spirits.'
