Still, even some cold brews that are brewed and sold as ready-to-drink (RTD) beverages contain higher levels of caffeine than your standard drip brew.įor instance, Stumptown Cold Brew Coffee is one of the first that comes to mind. However, as a concentrate, cold-brew coffee is also typically cut with water or creamer, which levels things out a bit. This alone leads to a higher caffeine concentration. While heat helps extract more caffeine, cold brew is typically brewed as a concentrate, with a higher than normal coffee-to-water ratio of between 1:4 and 1:8, compared with a more typical drip coffee ratio of 1:15 or 1:25. And though the numbers tend to vary by agency, the level of daily caffeine intake that is considered safe is between 400 and 450 milligrams.Ĭold brew is a different beast entirely. And a venti blonde roast is listed at a whopping 475 milligrams, according to Caffeine Informer.Ī single venti drip coffee from Starbucks alone contains more caffeine than the average American ingests in a day, according to a 2012 report by the FDA, which showed that number was around 300 milligrams of caffeine per person per day. Up that to a 20 fluid ounce venti (591 milliliter) and you're looking at 415 milligrams of caffeine. Its Pike Place house brew is listed at 260 milligrams for a 12-fluid-ounce (355-milliliter) cup. Starbucks, on the other hand, changes its caffeine content based on the roast level.
The caffeine content value changes dramatically, based on who you ask or where you buy your coffee.įor example, a 14-fluid-ounce (414-milliliter) cup of coffee from Dunkin' Donuts is listed at 210 milligrams of caffeine and a 24-fluid-ounce extra large (710-milliliter) has 359 milligrams of caffeine.
