Watch this space! Sadly, we don't have any coffees from Sumatra available at the moment.
There are very few coffee estates, or even co-ops, in Sumatra. Instead, a huge number of tiny growers - farms rarely exceeding three hectares - sell small quantities of coffee at their local village market. These farmers - many of whom are women - bargain hard, and prices for semi-prepared coffee are very high compared to Latin American and African standards.
