M Restaurant has announced that it is to sell its bottle of 1894 cognac for over £6000 for a 25ml shot – that’s the price of cognac history. The bottle is reputedly the first blend ever produced by Jean Fillioux, who founded the Fillioux cognac house. Snippets of history such as this are often priceless in the cognac world. Over the years we have sold many such historically important bottles to luxury hotels in London. The ultimate in super-premium spirits, these too have been sold by the measure for thousands of pounds. But to command this sort of price tag, each must have a story attached. Many were produced in the pre-Phylloxera era (pre 1875), when cognac production was considerably different from today, and produced by old family firms that may no longer be in existence. The vintage may also be attached to an event in history, such as the beginning of the French revolution in 1789, which adds to its interest and value. Selling very old cognac is a proven way of increasing bar takings but beware, establishing authenticity is a specialist business; we have been undertaking it for decades.
