Cold brew coffee is a smooth and refreshing drink that many people enjoy, especially during warm weather. Unlike regular coffee, which is made with hot water, cold brew is made by steeping coffee grounds in cold water for 12 to 24 hours. This slow process brings out a rich, sweet flavor that many coffee lovers adore.
Because of its unique brewing method, cold brew often tastes less bitter and is easier on the stomach. It also tends to have more caffeine than hot brewed coffee but just how much more? Let's find out.
How Much Caffeine Is in Cold Brew Coffee?
The amount of caffeine in cold brew coffee can vary a lot. On average, a cup of cold brew has between 150 to 300 milligrams of caffeine per 12 ounces. That’s more than a regular cup of hot coffee, which usually has around 95 milligrams in the same amount.
Cold brew is stronger because it uses more coffee grounds and a longer brewing time. Some brands and coffee shops make it extra strong, while others dilute it with water or milk. That’s why the caffeine content can be different depending on how it’s made.
Factors That Affect Caffeine in Cold Brew
1. Coffee Bean Type
Some beans have more caffeine than others. For example, Robusta beans have more caffeine than Arabica beans.
2. Brew Time
Longer steeping times usually mean more caffeine. Most cold brews are steeped for 12 to 24 hours.
3. Coffee-to-Water Ratio
Using more coffee grounds makes the cold brew stronger and more caffeinated.
4. Serving Size
Bigger cups mean more caffeine. A 16-ounce cold brew will have more caffeine than an 8-ounce one.
5. Dilution
Many people add water, milk, or ice to cold brew. This lowers the caffeine per sip.
Is Cold Brew Coffee Too Strong?
It depends on how your body reacts to caffeine. Some people can drink cold brew and feel great, while others might feel jittery or anxious.
Tips to enjoy cold brew safely:
- Start with a small cup.
- Add water or milk to reduce caffeine.
- Avoid drinking it late in the day.
Too much caffeine can lead to trouble sleeping, upset stomach, or fast heartbeats. So it’s important to know your limits.
