In North Sumatran coffee markets, the growers sell their coffee in wet parchment form. The coffee is sold by weight, but measured with a 2 liter volume canister called “tumba”. It equals 1.2 kg roughly.

The coffee parchment must be sold wet, meaning the moisture content is still high sometimes even 50% and the buyer, usually a middleman, will pay the weekly market price to the grower for this wet parchment coffee.

The Long rainy season here dictates many of the processing methods, and trading practices. It may seem odd to an outsider, but the system works. As long as no one abuses it. That’s another story.
