  • Fermentation and drying methodGeorge Howell says processing continues through drying on-farm, but the exact fermentation and drying protocols are not published.
  • Roast dateNo bag-specific roast date is published.
  • Formal grade fieldThe roaster publishes Kenyan AB screen grade, but the site schema cannot represent AA or AB; the generic grade field remains Not specified.
  • Numeric public sentimentThe qualifying exact-coffee source is qualitative and publishes no score.

From the producer

Patrick Mathagu manages Mamuto Farm in Kirinyaga, continuing the quality-focused work of his late father, Walter Mathagu. Coffee is processed and dried on the farm, then rests in parchment for approximately six weeks before final milling.

From the roaster

George Howell presents Mamuto AB as a fuller-bodied counterpart to the farm's more floral AA selections, with blackberry, blackcurrant, and plum in a light roast.

Why this coffee is noteworthy

A long-running direct farm relationship: George Howell Coffee has bought Mamuto since 2006. This AB selection emphasizes body and deep fruit while preserving the farm's signature blackberry character.

The honest process breakdown

WHAT DID THEY ACTUALLY
DO TO THIS COFFEE?

01
Lot identity

Confirmed Mamuto Farm, Patrick Mathagu, Kirinyaga, December 2025 harvest, washed process, AB screen grade, and 5,070-foot elevation.

02
Variety relationship

Connected the existing Field Blend record because the exact page identifies SL34 plus unspecified heirloom varieties.

03
Independent evidence

Replaced mismatched historical Coffee Review scores with one current exact-coffee qualitative Home-Barista source; no number was manufactured.

What was added?

Four editorial sections, current $34 availability, 1,545-meter converted elevation, harvest, mixed-cultivar relationship, and a transparent one-source qualitative sentiment record.

What wasn't added?

No cultivar proportions, lot-specific fermentation/drying method, bag roast date, or numeric public score was inferred.

Why it matters

The profile now separates the current December 2025 AB release from older Mamuto reviews and represents its documented mixed cultivar identity without creating a new variety.

What you might taste

Blackberry, blackcurrant, and plum with fuller body and a long finish.

Outside reviews and internet discussion — is kept clearly separate from our own review. When we taste it, our full review appears here.
