A Closer Look at the Carbon Dioxide Decaffeination Process
Our customers often ask us about how we decaffeinate our teas. Unlike other tea companies that use methylene chloride, a chemical solvent with reported health risks, we use carbon dioxide, a natural alternative to methylene chloride and the only decaffeination method approved for certified organic teas. Since we work so hard to source high quality organic teas, it’s just as important that our decaffeination process preserves our teas’ flavor and quality as much as possible.
To give you more information about how the carbon dioxide decaffeination process works: in a sealed chamber, moistened tea leaves are exposed to pressurized CO2, which has been liquefied under pressure. The liquefied CO2 bonds with the caffeine molecules in the leaves and after a few hours, the liquid is poured off and the tea is dried, evaporating both the CO2 and the caffeine. As caffeine is the only compound reduced, this process leaves the treated tea leaves more intact and flavorful than other methods.
We hope you’ll try all of our decaffeinated teas. Currently we offer a Decaf English Breakfast, Decaf Earl Grey, and Decaf Green in tea bags and a Decaf Black, Decaf Green, and Decaf Chai in loose leaf.
It’s important to remember that decaffeination does leave a trace amount of caffeine in tea, meaning the tea becomes decaffeinated, not caffeine free. If you are concerned about ingesting any caffeine at all, you’ll want to avoid decaffeinated teas and stick to herbal teas such as Chamomile, Peppermint, and Rooibos that never contained any caffeine. Note that Yerba Maté is our one herbal tea that does contain caffeine.
