One might have trouble topping this bottle of Cognac for rarest tipples in the world:
Said to be the last remaining hand-blown jeroboam (6 litre, smaller bottle shown above) bottle in the world and believed to have travelled with the army of Napoleon Bonaparte as it waged war against Austria and the British. The Dutch Republic fell to French troops in the same year. Bought from a Chicago collector in 1990 for more than €24,000. Estimated value €138,000.
Of course you can purchase some old and rare Joan’s Hole Vintage Damson gin at a fraction of the price.
