I make cold brew coffee for the week. The glass container I use is roughly 64 ounces. When I make it, I use about a cup and a half of ground coffee. I don’t use a scale to tell you the amount in grams.

So, 1.5 measuring cups of ground coffee steeped for 24 hours to make 64 ounces of black coffee. What is the approximate caffeine content of the entire pitcher?
