The importance of CO2 vs EA decaf.
Often overlooked, decaf teas have enjoyed steady popularity as an alternative for those seeking to reduce their daily caffeine intake. Firsd Tea offers many decaf tea products across types of tea, leaf cut, quality levels, and certifications.
It is helpful to understand how decaf teas are produced. Decaffeination is the process of extracting caffeine from tea (or coffee).
The 2 most common methods of large-scale decaffeination include:
The basic steps of CO2 decaffeination involve:
The CO2 process results in removal of 95-97% of total caffeine, which means caffeine levels of 0.2-0.4% caffeine by the leaf’s dry weight.
No- not all caffeine is removed during decaffeination. The US tea industry voluntarily accepts a standard of no more than 0.4% caffeine by dry weight. These teas are labeled as decaffeinated teas, and not as caffeine-free.
Caffeine-free is reserved for tea products that naturally contain no caffeine. Many herbal teas are caffeine-free.
