This is the only brand of vermouth I buy. Some things are too good to mess with.
This ad is from the May, 1964 issue of Playboy Magazine. I will probably share more scans from it at my other blog, liliales.
Classic Martini: 3 oz premium gin, 1/2 oz (1 tbs) Noilly Prat dry (French) vermouth, shake and strain and garnish with a lovely lovely olive. And an onion, if you're me. This is the contemporary standard of six parts gin to one part vermouth. People who sneer at vermouth probably aren't tasting the best stuff. It's not a martini without it.
Mer's Perfect Manhattan*: 3 oz premium bourbon, 1/2 oz Noilly Prat dry vermouth, 1/4 oz Noilly Prat sweet (Italian) vermouth, shake and strain into a cocktail glass or pour over a rocks glass with ice. Garnish with two cherries, because the bourbon makes them delicious, and you can share one.
*Usually a Perfect Manhattan has equal parts sweet & dry vermouth. A regular Manhattan has only sweet vermouth, and a Dry Manhattan only dry, both traditionally with a couple of shakes of bitters, which you leave out of the Perfect. I like my own balance best. However you make it, the proportion of four parts bourbon to one part vermouth works nicely.
