The Grassoti is very good but I have very few dry vermouths to compare with. General things I noticed vs M&R: Grassoti is lighter, less dry and has a wider bouquet of floral notes. I generally find it far more pleasant than M&R.
I decided to try an olive brine on its own because I am not a big olive eater (or rather was...they are quite good with a dirty martini). But had already fallen for the dirty gin martini and wanted to make it at home so bought Fever Tree based on my love for their tonic water.
Thank you! I had a lot of fun while, planning, making the drink and then setting up & taking the shot! (Also a fine excuse to pick up Viski crystal 😁)
