THE FIVE TASTES, READvs All-lots average
Acidity5.7RESTRAINED

Acids run below the comparison — expect a soft, rounded cup rather than sparkle.

Aroma3.9STRONG

An expressive aromatic feedstock — fragrance carries from dry grounds through the cup.

Flavor4.3RESTRAINED

A simpler, more linear flavor — comfort profiles and blends suit it.

Sweetness4.2RESTRAINED

Natural sugars are calmer than peers — build sweetness through the Maillard phase.

Body3.6STRONG

Lipids and polysaccharides build real weight — holds up in espresso and milk.

07THE ROASTING PLAYBOOK
How to get the most out of it · derived from the chemistry
01
Build depth early

Acidity is gentle — a slightly longer Maillard adds roundness without flattening the cup.

02
Build sweetness in the Maillard

Natural sugars are on the calmer side — stretch the yellow-to-brown phase for rounded sweetness.

03
Position the light body

Frame the delicate mouthfeel as transparency, not a flaw — strongest in filter.
