The video above is an updated, more recent post. The original recipe video (I ripped the videos from Small Screen Network before they shut down) uses Dry Sack Medium Sherry (a blend of Amontillado, Oloroso and Pedro Ximenez) and Fee Brother's Peach Bitters. So it's quite a bit less dry than a version using just Amontillado and The Bitter Truth Peach Bitters (which are much more bitter than the Fee's). The Trident is a drink I really gravitated to when it came out, maybe as much for the drink itself as it encouraged me to explore my own Negroni variants. I personally like using Krogstad Aquavit (it's a cleaner, crisper flavor than the oloroso cask barrel aged Linie) and a 50/50 split of Amontillado and East India Sherry.
