How Much Caffeine Is In Cold Brew?
The caffeine content of cold brew varies greatly. You can buy this coffee in a ready-to-drink state at a supermarket, from a coffee shop, or制作冷冲泡咖啡浓缩物yourself. Each option can have widely different amounts of caffeine.
例如，Stok Cold Brew每份咖啡因145mg。来自Stumptown的类似饮料每份有279毫克。作为一个过高的例子，Bizzy的每份有750毫克（1); however, this is not a typical caffeine level for a cold brew.
From Starbucks, a tall cup of cold brew has 155mg of caffeine. In comparison, a similar drink at Dunkin Donuts has 174mg per serving (2).
400mg is regarded as a safe intake of caffeine per day, so most of these beverages are within a healthy range (3).
Why does It have more caffeine?
Cold brew has a lot of benefits包括较高的咖啡因含量。由于咖啡与水的比率，自制版本最初具有更多的咖啡因。初始批次使用的咖啡比产生相同液态的热酿啤酒方法多两到三倍。
A coldbrew concentrate can have over 500mg of caffeine per 8oz of liquid, while a hot brew of equal volume usually has about 100mg. However, the resulting mixture is not a ready-to-drink beverage like the hot brew method.
Well, Is It Stronger?
Surprisingly, if ratios of beans to water are equal, caffeine is higher in hot brew coffee. This is due to the effect hot water has on caffeine in the beans.
咖啡因的溶解度主要是由温度驱动的，因此，在较高的温度下，咖啡因明显比在较冷的温度下溶解在溶液中。
Quite differently to this process, 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.
Many ready-to-drink cold brew have more caffeine than their chilled coffee counterparts because manufacturers use more coffee in the production process. However, if you make your own batch of this drink, 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.

FAQs
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. Here’s where wecompared iced coffee and cold brew.
Cold brew does not necessarily have more caffeine than espresso. On average, 50ml of cold brew has about 85mg of caffeine, equivalent to 30ml of espresso. It might seem like cold brew contains more caffeine because of the way it’s prepared and consumed. But simple mathematics tells us it does not.
Many people consume cold brew faster. Cold brew is a refreshing coffee drink, so people tend to drink it differently to regular coffee. The jitters can come from the rate of caffeine consumption and not necessarily the amount. However, people on coffee forums say they’re more likely to get jitters from regular coffee than cold brew. So this is also a subjective matter.
