I was at a cocktail dinner a few months ago where DeGroff was there and made several drinks that used this (and his bitters). By itself the amaro reminds me of Fernet-Branca, but more enjoyable at least to me. In cocktails (in small amounts) it is very nice . . . the bottle or the website has a mai tai variant using 1/2 oz of this that is surprisingly good.
