Here’s a comparison of the strength, blend and size of the serving:
Coffee: 75 mg per small cup
Decaffeinated coffee: 3 mg per small cup
Tea: 17 mg per small cup
Some pain killers: 50 mg per individual dose
Coke: 20 mg per small glass
The freshness of your coffee will depend on if you purchased canned, bagged or single-serve coffee. Canned coffee stays fresh for over two years, thanks in part to the strength of the seal. Bagged and single-serve coffee will stay fresh for up to one year after it was roasted.
