Touching back on this after a 3rd listen. Like Nate, I also love rolling out in the morning with a small bottle full of cold coffee. I usually take my leftover pour-over (that I make extra on purpose) and toss it in a bottle overnight in the fridge.
That cold, bitter taste is my first bottle during the ride and a great contrast to the sweet of my food and other drinks. I will also snag a cold coffee sometimes mid-ride at a gas station during my long endurance rides for the same reason.
