In 1905, Ludwig Roselius patented a decaffeination process using hot water and benzene to remove caffeine from raw coffee beans. He founded the brand Kaffee HAG and later introduced Sanka, which gained popularity in the US market. Early marketing promoted decaf as a healthier choice but faced issues due to the use of benzene as a solvent.

Decaffeination with Organic Solvent The decaffeination process using organic solvents like methylene chloride or dichloromethane is similar to the original process. These solvents are used to extract caffeine from coffee beans by steaming or heating them up in hot water. Despite concerns about their safety, well-processed decaf coffee using these solvents remains below the recommended limits for exposure.

'Supercritical Carbon Dioxide' Decaffeination Process 'Supercritical carbon dioxide' is a unique method that uses CO2 under specific temperature and pressure conditions to act as a liquid and extract caffeine from coffee beans. This process does not alarm people because CO2 is naturally occurring and not considered scary in normal amounts.

Decaffeinated coffee is often described as 99.7% caffeine free, but it actually contains up to 0.3% caffeine by weight according to EU legislation. This reduction from normal caffeinated coffee is significant, going from around 1-2% down to under 0.3%. However, decaf coffee can still contain a small amount of caffeine that may not be detectable by standard testing devices due to its low concentration.

Chlorogenic acids, present in high quantities in decaf coffee, are polyphenols that contribute to gut health. Decaf coffee contains loads of CGA and polyphenols, which can benefit gut health without the stimulating effects of caffeine.

Roasting decaf coffee beans is challenging due to the irreversible structural changes that occur during processing, making them more porous and altering their heat transfer properties. This results in a different roasting process compared to regular coffee, often leading to inconsistent roast levels and oily-looking beans.

Decaf coffee stales faster than caffeinated coffee of kind of matching roast levels. Decaf is more porous, allowing oils and air to affect it more easily.

The Importance of Freshness Dark roasted decaf coffee stales quickly, losing quality and flavor within two weeks. Many cafes overlook the freshness of decaf, leading to a lack of investment in its quality. Buying great decaf from a roaster that cares deeply about their product is crucial for an enjoyable experience.
