Thanks for the review. One question: what is the shelf life of this non-alcoholic liqueur? Does it require refrigeration?

An absolute favorite! Amaro Montenegro's bitter fruitiness is perfect in a manhattan or reverse manhattan - delicious.

Cocchi Americano is definitely a favorite. I slightly prefer spirit-based liqueurs as the shelf life is longer. For vermouth or Cocchi, I store in the fridge, but even then it is important to use relatively quickly. Some favorite drinks that use Cocchi Americano: Cocchi Irlandese, Vesper, Corpse Reviver #2. Really, you can add it to any drink to cut the sweetness and add a little bitter goodness.
