As an experienced barista and coffee taster with 20 years under my belt, I can tell you that the best coffee isn’t always the one with the most caffeine. In fact, when you’re sipping on your morning brew from your favorite coffee shop online, you might not be aware of the fascinating journey those beans have taken from the coffee roasters to your cup, especially if you’re indulging in a fine Colombian Coffee.

I prefer decaf coffee… well, do you know what “decaf” means?

What about :
Low caffeine level in coffee by Nature
And not Decaf coffee?
 
A coffee can be low in caffeine by Nature when you purchase 100%  Arabica Beans grown in high altitudes, 1200 masl and up in Tropical climates like the mountains of Colombia.

The mountains in Colombia go from 1200 masl (meters above the sea level) to 1850 masl , the highest the mountains the less caffeine in the beans.

Colombia produces  only ARABICA BEANS which have softer characteristics and less caffeine different than ROBUSTA BEANS for example from in Brazil where the altitudes are from 800 masl to 1200 masl where the caffeine concentration is higher just by nature.
 
ARABICA Beans have between 0.8 to 1.4% caffeine level,
ROBUSTA Beans  have between 3 to 7% caffeine level
 
Being this said then let’s define DECAF coffee:  it is an Industrial chemical process and it will never be 100% free of caffeine, the beans lose the flavor and aroma of the natural coffee and  it will always have a remaining % beside the effects it can cause to your health since those additions in the process used to extract the caffeine are:
*CO2 pressure with carbon dioxide
*Benzene solvent
*Methylene Chloride
*Ethyl acetate extracted from sugar cane
And the best option which would be the healthiest  but the more expensive is:
*Vapor / Water (Swiss water).
 
Before you take a DECAF coffee ask for what kind of process was used to extract the caffeine, instead try to drink high altitude Arabica coffee which is low in caffeine just by nature and will not affect your health in the long term.
