Ngila Estate Kent AB
86.0Cup Score
Grown on the edge of Tanzania\u2019s Ngorongoro Conservation Area, this washed Kent AB lot comes from Ngila Estate\u2014a farm nestled between cloud forest and the wildlife corridors that cross northern Arusha. At 1,600 metres above sea level, cool temperatures and rich volcanic soils provide the foundation for bright, structured coffees like this one.
Harvested in July and August 2024, the cherries were carefully hand-sorted, pulped, and washed on-site at Ngila, then fermented for 15 hours before being dried on raised beds for two weeks. Once fully dried, the lot was hulled and prepared for export at Rafiki Mill in Moshi.
Ngila has a long history in Tanzanian coffee, first planted in the early 1900s and now run by Vera St\xfccker and a dedicated local team. The farm is Rainforest Alliance certified, and sustainability runs through everything they do\u2014from tree planting and biochar use to water conservation and community investment.

Roasting Notes:

Probably should have stepped down to 40 instead of 30 around the 7 minute mark, and increased airflow a bit (from 25->30) around that same time.

Reckon if I had to repeat this, it would be:

Preheat: Drum 80, Air 25, Burner (Manual) 100, SV=230
Pre-charge @BT = 230: Burner off, beans in
Post-charge: SV= 200, Burner 60 (No change to drum or air)
At dry end: Burner 50 (No change to drum or air)
1 minute to FC: Burner 40, Air 30
@ 12% development: Burner 20 (No change to drum or air)
@ 20% development: Burner off
@ 25% development: Drop

Cupping Notes:

Tried as Clever Dripper - very sweet, very clean acidity. No harsh notes; though sweet/acid notes are quite mild.
