Duff Energy Drink is a novelty energy drink that is based on the Homer Simpson's favorite beer in the cartoon series The Simpsons.

The 12 ounce can has the exact same design as the TV show - but it is not beer!

The drink reportedly has an orange flavor.

The Caffeine in Duff

The can lists caffeine as 114mg but they also list 25mg of guarana, so we estimate the drink to be around 120mg of caffeine since guarana provides some caffeine.
