Does iced (cold roasted) coffee have more caffeine retained in the beans than hot coffee?

Answer 1

All coffee beans are roasted prior to becoming coffee. Roasting is strickly a hot, dry method of cooking. Lighter roasts DO, however, retain more caffiene. Espresso roast actually contains less caffiene. But it is concentrated.

Answer 2

You cant cold roast coffee. You need heat to roast. If you are referring to brewed coffee, I would hazard a guess that there would be less caffiene leached from the grounds if you only used cold water.
