Coffee is good. Really good. But which coffee will give you the biggest boost? That’s a question many of us ask ourselves when we’re dragging our asses into the coffee shop each morning or digging through the cupboard to find the grinds.
Well, it’s no surprise that espresso has a high caffeine content: that’s 45-75 milligrams per ounce. Drip coffee sports a mere 20 mg per ounce but size is a big deal, as all of us have grabbed the 16 oz coffee at the shop: so two ounces of espresso is around 150 mg of caffeine, 12 oz of drip coffee hits the 240 mark, 16 oz. of drip equals around 320 mg and a 20 oz hits around 400 mg of caffeine.
