There is definitely more caffeine in cold brew. The reason is extraction time.Results:
Straight up: Very smooth, little brightness or acidity. Caramel, cocoa, and earthiness much more apparent.
Mixed 50/50 with milk, sugar, and ice: Tasty, but I need more coffee flavor. Perhaps a darker roast next time.
10 hrs later, I am still wired. Perhaps there is a higher caffeine concentration? I only had 8 ounces of the coffee.
Next time, I am going to increase the amount of coffee.

Water temperature affects not only the rate of extraction, but also the substance that is extracted.Did you try more coffee and like it better? I wanted to like cold brewed coffee but in the final analysis it felt like I was only getting 1/2 the coffee taste, so I abandoned it. All the top end brightness was gone when brewing that way, leaving only the body. It tasted quite good when mixed with lots of milk, but I generally like to drink mine black, so I continue to hot brew.
