## What the Brand Says

> Sumatra - Alko Co-Operative Carbonic Maceration Natural Varietal – Andung Sari, Sigarar UtangPreparation – Carbonic maceration naturalLocation – Kayu Aro, Kerinci, SumatraAltitude – 1300 maslImporter - Nordic Approach Producer Overview The Alko co-operative has about 416 members covering a growing area of about 320 hectares. They grow coffee from 1300 - 1650 masl, its mixed varieties, but mainly Sigararutang and Andung Sari. This carbonic maceration natural processed coffee is an experimental micro lot processed from coffee grown by Fatar and Horti Tani. Their coffee was selected for this special process due to the high quality and very even ripeness of the harvest. Finding coffee like this from Sumatra is quite a challenge! Coffee from Indonesia often doesn't showcase the bright, intense, fruity profile that we enjoy from many other origins. This is often simply because producers aren't focusing on the correct techniques required for these coffees. This micro lot is truly stunning and showcases some incredible flavours. Harvesting and Processing: The coffee was processed using the following method: Manual hand sorting and water flotation to remove defects Fermenting in sealed containers for 96 hours. Coffee dried in a thin layer for 5 days undercover. The coffee layer was built up to slow down the drying taking about 25 days. Tasting Notes: Tropical fruits including pineapple, prune and dark chocolate. This is a stunning carbonic maceration natural showcasing intense fruit flavours.
