How Much Caffeine Is in Decaf Coffee and Tea?

Just How Much Caffeine Is in Decaf?

Ever since my week of clean eating, I've tried to limit the amount of caffeine I ingest. So instead of my normal morning cup of coffee, I've been substituting with green tea or, if I can't resist, a trip to the cafe for a decaf soy au lait.

Some days I go without, but I know that my regular cup of tea or decaf still has relatively small levels of caffeine in it. But since too much caffeine can lead to problems such as insomnia, nervousness, irritability, or irregular heartbeat, I'd thought I'd learn more about just how much caffeine is in those decaffeinated drinks.

Regular drip coffee usually contains about 85 mg of caffeine per eight-ounce cup, while the average cup of black tea contains about 50 mg and green tea 40-50 mg per serving. Want to know how decaf options compare? Read on after the break.

Drink Amount of caffeine
Average drip decaf coffee (16 oz.) 8.6-13.9 mg
Folgers Instant Decaf (16 oz.) None
Starbucks grande decaf latte (16 oz.) 6-32 mg
Starbucks grande brewed decaf (16 oz.) 12-13.4 mg
Decaf black tea (16 oz.) 4-20 mg
Decaf green tea (one serving) 1-8 mg

The coffee stats were taken from a study published in the Journal of Analytical Toxicology, which found that caffeine levels in different decaf options vary widely. In fact, the researchers tested out several Starbucks espresso samples and found a wide range in caffeine levels but noted that some Starbucks grande decaf lattes — which are made with two shots of espresso — contain as much caffeine as a can of Coke!

I love the taste of coffee, so I'm probably going to continue ordering an occasional cup of decaf. After all, going decaf means much lower levels than a regular cup of Joe. I may steer clear of those Starbucks lattes though. How about you; if you've gone caffeine-free, do you stop drinking all types of coffee and tea?
