The source introduces a Nicaraguan Laurina offering and discusses the variety's association with naturally lower caffeine. That botanical description is different from a coffee that has undergone a decaffeination process. Neither should be interpreted as a guarantee of zero caffeine in a finished drink. The source distinguishes naturally lower-caffeine pointed Bourbon from coffee that has undergone decaffeination; these are different production routes and should be labelled clearly.
Ask for the producer, variety, harvest and available product information. A commercial description such as half-caffeine needs support if the exact amount is important to the buyer; it should not be inferred from a variety name alone. Origin and processing also remain relevant to the sensory profile.
Treat the coffee as an individual lot when brewing. Use a measured recipe and record sweetness, acidity, body and finish rather than judging it only by the caffeine story. This profile does not establish medical suitability or provide a laboratory result. Questions requiring a precise caffeine amount call for reliable information about the actual product and serving.

A good question can make a better brew.
