The price of Hennessy depends greatly on a number of factors, including location and bottle size. Each store or restaurant sets its own price for a given quantity of Hennessy.
Not only does the cost of Hennessy cognac depend on location and bottle size, the cost is also affected by which collection the Hennessy is from. For example, a bottle of Hennessy V.S generally costs less than the same size bottle of Richard Hennessy and other reserved varieties. Likewise, purchasing Hennessy for immediate consumption in a bar or restaurant often carries a higher price tag than the same amount in a bottle.
