One of world's largest private cognac collections on sale

Bay van der Bunt claims his is the world's largest and most unique private cognac collection- and he's putting it up for sale.

He started buying bottles of cognac some 40 years ago, following in the footsteps of his father and grandfather, despite the fact that he doesn't drink.

The collection in Holland includes 5,000 bottles of old spirits and liqueurs, with some dating back to the French Revolution and Napoleon Bonaparte.

The 63-year-old collector says he never thought of it as an investment, and now he is selling it with "pain in my heart".
