If you actually want to taste the character of the vermouth (I think 10:1 is the limit) as opposed to just modifying the flavoring of the Sapphire, be sure to use a new bottle of Noilly Prat. Even when I cover the newly opened bottle with nitrogen and keep it in the fridge, my two most discerning Martini drinkers can tell the difference. They say it is least as much of a difference as power cords.
Best Martini s
I am tired of seeing threads only about things I don't drink(sorry beer and scotch fans). I like Martini's and maybe others out there do also. I prefer mine with Bombay Saphire gin and Noilly Prat French Dry Vermouth. Start with a boston shaker 2/3 full of ice cubes, then add room temp. gin (I usually use 2 jiggers of gin but I have large glasses) and then add a quick mist of chilled vermouth after the gin is comfortable with the ice and proceed to shake the hell out of it. Then strain into a chilled cocktail glass(I prefer Riedel crystal) with NO garnish, I once heard a saying "garnish is a speed bump on the road to bliss". Any other martini fans out there? what do you prefer?
