Embu provides the regional context in the source's Kenyan coffee profile, while PB indicates a peaberry designation. An unusual seed form can be interesting, but it should not be mistaken for a variety or a promise of better flavour than every flat-bean lot. The article discusses an Embu peaberry lot with a reported review score, making the region, seed selection and individual evaluation three distinct parts of its identity.
The source also discusses an earlier reviewed coffee. Keep any assessment tied to the specific lot and date rather than transferring a score to all Embu coffees. Producer or station identification, processing, harvest and roast remain important when examining a current offer.
Use a measured brew and note the relationship between acidity, sweetness, texture and finish. Compare the seller's descriptions with your own observations after tasting. A regional guide becomes more useful when it helps distinguish products and understand labels, without claiming that BeanScene has judged the lot or verified another organisation's score.

A good question can make a better brew.
