Cold brew coffee is generally less strong than French press coffee. This is because cold brew coffee is made by steeping coffee grounds in cold water for an extended period of time, typically 12-24 hours. This slow method of brewing results in a coffee that is smoother, with less bitterness and acidity, but also less concentrated. In contrast, French press coffee is made by steeping coffee grounds in hot water for a shorter period of time, resulting in a stronger, more robust coffee. However, the strength of coffee can also depend on various factors such as the type of coffee beans used and the brewing ratio, so it can vary from person to person.
