Cold Beer and Regular Coffee Are High in Caffeine
Is your cold drink stronger than regular coffee? It turns out this is a trick question. A cold beverage may not actually extract as much caffeine as hot brew methods, but often the finished beverage is concentrated enough to compete with hot coffee.
This is because a cold drink is usually made with a ton of coffee grounds, but then the barista dilutes it with some water, milk and / or ice. The caffeine content depends on how concentrated the original drink was and how much of it in your drink. This makes it difficult to predict the caffeine content.
Take Starbucks cold drink, for example. A 16-ounce cup contains 200 milligrams of caffeine, compared to 165 milligrams in a cold coffee of the same size. So cold beer is stronger, isn’t it?
But they are made differently: Iced coffee starts with double strength hot coffee and poured onto the ice (which dissolves into the coffee, diluting it). To prepare a cold drink, you need to soak a large amount of coffee in a little cold water for 20 hours. In this case, the cold broth is more concentrated. But if you ordered 16 ounces of hot coffee, of course no ice, there would be 310 milligrams of sweet, sweet caffeine in a cup of the same size .
On the other hand, if you buy a bottled cold drink and drink it without thinning, you will have a serious dose of caffeine: for example, 279 milligrams in a 10.5 ounce bottle of Stumptown , which beats our hot drink example above in ounces. comparison of ounces.
