400mg is regarded as a safe intake of caffeine per day, so most of these beverages are within a healthy range (2).

Why does cold brew have more caffeine?

Homemade cold brew initially has much more caffeine due to the coffee to water ratio. An initial batch of cold brew uses two to three times more coffee than a hot brew method that yields the same liquid amount.

A cold brew concentrate can have over 500mg of caffeine per 8oz of liquid, while a hot brew of equal volume usually has about 100mg. However, the cold brew method’s resulting mixture is not a ready-to-drink beverage like the hot brew method.

Caffeine’s solubility is primarily driven by temperature, such that at higher temperatures, significantly more caffeine will dissolve in solution than at cooler temperatures.

Cold brew has more caffeine because the brewing process uses more coffee. More coffee means the brew has more potential to become extremely potent. If hot brewing used as many beans as most cold brewing methods, the resulting beverage would have much more caffeine.

Coffee to water ratio is the biggest factor in caffeine levels of cold brew coffee.

Many ready-to-drink cold brews have more caffeine than their chilled coffee counterparts because manufacturers use more coffee in the production process. However, if you make your own cold brew, you can control the amount of caffeine. Simply use less concentrate in your morning cup if you want to lower your caffeine intake. Alternatively, you can increase the amount of concentrate if you want more caffeine.
