Have you ever thought if the amount of caffeine in hot brewed coffee and cold brew coffee is the same? Most of the time I drink cold brew. I like cold brew concentrate a lot, and I was wondering how much caffeine there is in cold brew coffee.
So, I’ve done 11 hours of extensive research reading scientific papers and studies to learn all the details about how and what affects the amount of caffeine in cold brew concentrate. To make it more clear to you, I’ve also written how much caffeine is in all the different cold brew concentrate brands.
It will be interesting to learn about caffeine and how coffee beans are made.
How Much Caffeine in Cold Brew Coffee?
The caffeine content of cold brew coffee is 200 mg per 16 oz (473 ml) drink. When it comes to caffeine, there isn’t much difference between a cup of hot brewed coffee and a cup of cold brewed coffee. The amount of caffeine in 16 oz. of hot brew coffee is close to 190 mg.
Cold brew concentration, on the other hand, has more caffeine than cold brew coffee. The difference between cold brew coffee and cold brew concentrate is the coffee-to-water ratio.
When it’s time to serve, cold brew concentrate is diluted with ice, milk, or water. The amount of caffeine changes, then.
In short, an 8-ounce dose of hot brew coffee, cold brew coffee, or coffee made with cold brew concentrate has between 95 and 105 mg of caffeine.
In the U.S., 85% of people drink at least one caffeine-containing drink every day. The average amount of caffeine people take in each day is 165 mg, which is about the same as two cups of coffee. Coffee is the most common way for people in the United States to get caffeine. Tea, soda, energy drinks, and food are the next most common ways.
Here is a table summarizing the different coffee concentrates along with their respective caffeine content:
|Caffeine Content (mg)
|Cold Brew Coffee (16 oz)
|Hot Brew Coffee (16 oz)
|Cold Brew Concentrate
|Starbucks Cold Brew Concentrate (11 oz)
|Starbucks Cold Brew Concentrate Espresso (1.5 fl oz)
|Starbucks Cold Brew Concentrate Caramel Dolce (per oz)
|16 mg (diluted 1:2)
|Starbucks Nitro Cold Brew (12 oz)
|Starbucks Nitro Cold Brew (16 oz)
|Chameleon Cold Brew Concentrate (8 fl oz)
|Kohana Cold Brew Concentrate (per fluid oz)
|Homemade Cold Brew Concentrate (8 oz)
|Grady’s Cold Brew Concentrate (8 oz)
Please note that these values are approximate and can vary based on factors such as coffee bean type, grind size, brewing time, and other brewing variables.
What Factors Affect the Caffeine Content of Cold Brew Coffee?
The amount of caffeine in cold brew coffee depends on the type of coffee bean, how it’s ground, how it’s brewed, how long it takes, how hot the water is, how much coffee you use, and how much water you use. Caffeine is a natural part of coffee beans, and it does not change when the beans are roasted.
Coffee Bean Type
Among the two types of coffee beans, naturally robusta beans have more caffeine than arabica beans. In fact, a study from 2016 suggests that robusta beans have twice the amount of caffeine as arabica beans.
Dry arabica coffee beans weighing 1 kilo have 34.1–38.5 mg of caffeine.
Dry robusta coffee beans weighing 1 kilo have 68.6–81.6 mg of caffeine.
Brewing coffee with smaller coffee grounds produces high caffeine coffee. Espresso made with small grind coffee is high in caffeine, as caffeine in one shot of espresso has 63 mg.
That is why coffee made with smaller grounds in a larger volume has more caffeine.
Brewing Time and Temperature
Caffeine and the temperature of the water are very important. Hot water speeds up the process and gets more caffeine out of the coffee than cold water. Because caffeine dissolves at 100 degrees, making coffee at a lower temperature can change how much caffeine is extracted.
But when analyzing caffeine, brewing time is not a significant component.
Coffee To Water Ratio
The coffee-to-water ratio has the greatest influence on the caffeine content of the brew. The type of water will not affect the caffeine extraction but will impact the flavor and aroma of coffee.
There are many things that affect how much caffeine is in the bean. There are also more than a dozen kinds of cold brew concentrate.
