Caffeine on coffee has been on the spotlight lately. This is due to the fact that there are some food and drinks that have more than the recommended daily consumption of caffeine. This is why we are left to wonder, how much caffeine does our usual Starbucks, Dunkin Donuts or McDonalds coffee to go have?
Jessica Reynolds wrote that if you are a usual coffee to go drinker, you may not feel the caffeine effect difference. You may felt that the taste is different than the other though. But for sure, levels of Caffeine varies from different coffee brands.
Caffeine levels vary by coffee brand
A 16-ounce Starbucks coffee contains 330 milligrams of caffeine — more than twice the caffeine of a 16-ounce McDonald’s coffee, which contains 145 milligrams. Dunkin’ Donuts coffee contains slightly more caffeine (206 milligrams) than the McDonald’s brand, but clearly doesn’t come close to rivaling Starbucks.
Why the vast difference?
Caffeine levels in coffee depend on a variety of factors including proportion (the ratio of water to coffee), brewing method, roast and the type of coffee beans, said Zack Hutson, spokesperson for Starbucks.
“Of all the factors, proportion is the most important in determining the caffeine levels in a cup of coffee,” Hutson said. Starbucks uses two tablespoons of coffee grains per six ounces of filtered water.
Starbucks sticks to that ratio because that’s “the taste profile our customers love,” Hutson said.
Asked why their coffee had substantially lower amounts of caffeine compared to Starbucks, McDonald’s spokesperson Danya Proud said her company could not confirm the FDA findings, as “we do not know the process by which this calculation was made or what blend of our coffee was tested.”
McDonald’s would not disclose its coffee-to-water ratio, explaining that it is considered proprietary to the company’s coffee blends, Proud said.
