Caffeine content of Coffea arabica var. laurina

Thomas W. Baumann · Phytochemistry 49(6) · 1998 · agris.fao.org

The measurement behind the Laurina caffeine figure. Establishes roughly 0.6% caffeine by dry weight against about 1.2% for standard arabica.

How much weight this carries

Well established. Safe to rely on as stated.

What it says

  • Laurina measures around 0.6% caffeine by dry weight — Approximately half the roughly 1.2% typical of standard arabica.

What it does not say

  • Half is not decaf. A cup of Laurina carries far more caffeine than a cup of decaffeinated coffee, and describing Laurina as a decaf alternative for caffeine-sensitive drinkers is a meaningful error.

Recorded because the errors in this subject all point one way: toward claims more confident and more flattering to decaf than the evidence supports.
