Yep, best to look online. It is based on (apparently) the recipe for the very first vermouth ever, with Giuseppe Carpano apparently being the inventor of vermouth as a commercial category of aromatized wines. It kind of tastes like a mix of a typical (if a bit rich) sweet red vermouth, with the vanilla and dried fruit aspects reported of Carpano Antica, but not as intense. I also had Cocchi Torino and they end up being very similar in terms of taste.
I enjoyed a lot of head-to-head testing on vermouths and Negronis. I find the Cocchi Storico much more complex and use it in most cocktails that expose the vermouth. OTOH, the Carpano is my choice for a Negroni (my notes):
Excellent bitter(sweet) with the Cocchi Storico, layered, orange glints and notes. Even better with the Carpano Antica Formula, which gives a more harmonious drink.
