So, which is stronger? If you compare the same amount of cold brew to iced coffee, the cold brew is going to have more caffeine. This is because the ratio of coffee to water is so much greater, with iced coffee being more diluted.
However, cold brew is slightly higher in caffeine than iced coffee. Additionally, a 16-ounce (473-mL) serving of cold brew also contains more caffeine than a 1.5-ounce (44-mL) serving of espresso. Although cold brew is made using more coffee beans than hot coffee, it may have slightly less caffeine in some cases.
One of the biggest myths about cold brew is that it's always strong and highly caffeinated. This isn't exactly true. What is true is that because it's brewed with a higher ratio of coffee to water, the concentrate that is made can have considerably more caffeine than the same volume of hot brewed coffee, even espresso.
However, most cold brews are in fact brewed stronger than hot coffees. Our cold brew recipe uses an 8:1 ratio of water to coffee grounds, making it twice as strong as the common hot brew ratio of 16:1. Remember though, that you're usually watering down cold brew with ice, water, or the milk or creamer of your choice.
Cold brew usually has more caffeine than iced coffee. Iced coffee is regular hot coffee served over ice, so it can quickly become diluted. Because of this, an equal amount of cold brew coffee will have more caffeine than iced coffee because it is not as diluted.

Iced Coffee vs Cold Brew
The difference between cold brew and iced coffee is that iced coffee is brewed with hot water while cold brew is brewed with cold water.
Cold brew is a different beast entirely. 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. This alone leads to a higher caffeine concentration.
Cold brew is stronger than espresso. It has a higher caffeine content because the coffee is steeped in cold water for a longer period of time. This results in a less bitter flavor and a smoother texture. And the longer you leave it, the stronger it becomes!
The coffee brand that has the most caffeine content is Biohazard Coffee, with 928 mg of caffeine per 12-oz. mug.
An Australian study investigating five popular types of coffee brewing methods has found that espresso contains the highest concentration of caffeine.
The most concentrated coffee type is a ristretto – this contains relatively the highest level of caffeine. However, a lungo is larger and thus contains more caffeine than a ristretto. Based on concentration levels of caffeine, these would be the strongest coffee types: RISTRETTO.
An Americano contains less caffeine than cold brew coffee does. This is because while making both coffee drinks, an Americano only uses two shots of espresso, whereas cold brew uses coffee beans that have been steeped for a longer duration of time.
Even if you would normally add a whole bunch of extras to a conventional cup of coffee, there's a good chance you'll love untainted cold brew. This is because cold brew coffee is naturally smoother and sweeter than regular coffee, eliminating the need for excessive quantities of cream, sugar and so on.
Because cold brew uses time instead of heat to extract the coffee's oils, sugars and caffeine, the end result is generally less acidic and bitter than iced coffee. If you're short on time, you can use purchase a pre-made option from the grocery store.
Cold brew coffee contains compounds that may reduce your risk of heart disease, including caffeine, phenolic compounds, magnesium, trigonelline, quinides, and lignans. These increase insulin sensitivity, stabilize blood sugar, and lower blood pressure ( 9 , 10 ).
Many of their drinks are made with 3 shots so that can be up to 225mg of caffeine in a single cup of joe. Your average concentrated cup of cold brew contains 150-250mg of caffeine, and a Starbucks Cold Brew has a caffeine content of 200mg in their Grande (16 fluid ounce option).
Because cold brew is made with cool water, it tastes slightly sweeter, a bit milder and way less acidic than your average iced joe. Though the aroma and flavor will be less intense, they won't change dramatically over time like hot coffee.
Higher Concentration of Caffeine
For example, a 16 ounce cup of Starbucks cold brew coffee has about 200 mg of caffeine. Caffeine is a compound that can sharpen your mental faculties and keep you more awake.
Iced coffee, like hot coffee, keeps you awake while also assisting you in staying awake. Caffeine is present in coffee, tea, chocolate, and cocoa as well as other drinks and foods. Cold brew coffee is made from water extracted through an unheated process that is cooled in a refrigerator after it has been extracted.
Cold Brew: Cold brew usually contains around 200 mg of caffeine per 16 ounces. Iced Coffee: Iced coffee has an average caffeine level of about 85 mg per 8-ounce cup of brewed coffee.
Your steeping time is too short or too long
However, the brewing process slows down in a cold fridge. So, add at least another 3 to 6 hours for fridge brewing. If your brew is too weak, steep the grounds for a couple more hours next time.
Cold brew coffee is simply a concentrate of coffee that's brewed for many hours at room temperature, then poured over ice and diluted with water, milk, or a milk substitute.
Accountant Lee Dae-hee told AFP he drank iced Americanos exclusively because it was a faster and more efficient caffeine hit, essential in South Korea's hard-driving “ppalli-ppalli” — hurry-hurry — work culture.
