Coffee Information

Country: Indonesia, Sumatra

Name: Wahana Estate Mandheling

Processing Method: Natural Process

Flavor: Upon entry, there's a rich ginseng aroma that emerges. The acidity is low yet powerful, somewhat like the texture of ripe plums, with a full brown sugar sweetness. The body is thick, making it difficult to associate with washed beans.

If you're accustomed to drinking common types of Mandheling, you can try this rather different Mandheling.

FrontStreet Coffee Recommended Brewing:

Dripper: KONO dripper

Water Temperature: 88°C

Grind Size: Fuji Mill grind level 4

Brewing Method: Water-to-coffee ratio 1:14, 17g coffee grounds, first pour 25g water, 30s bloom, second pour to 238g water, extraction time around 2:30 minutes.

Analysis: The KONO dripper doesn't have many ribs at the bottom, and the filter paper fits tightly against the dripper, achieving the purpose of restricting airflow. This allows water and coffee grounds to have longer contact and soaking time in the dripper, ensuring extraction time and rate for coarse grinding. This allows the coffee grounds to be fully extracted, enhancing the rich mouthfeel and making the flavor more concentrated.

Flavor: High balance, clean, thick and solid mouthfeel, persistent dark chocolate aftertaste.
