Yeah, the difference is naturally occurring L-theanine.
Energy drinks like Monster add it in to prevent the "jittery" feeling that is associated with coffee. Teas like assam and mate have l-theanine, but I'm not sure about cold brew - maybe it allows for more extraction with the longer brew time?
Some nootropic-minded folks supplement with powdered l-theanine for this reason.
