This study of the brandy trade explores the origins, production and marketing of brandy from the Cognac region in the seventeenth and eighteenth centuries. Professor Cullen shows that the brandy trade was based on a sophisticated regional economy, which, by 1720, had become a key component of French involvement in the modern international trading system. Notwithstanding competition from a surplus in other cereals and from foreign markets, regional specialization in the Charente was an indispensable element in ensuring the quality of stable output, and was recognized in the region's success in attracting foreign houses, such as Martell and Hennessy.
