While I much prefer more vermouth in my Martini than is used here, I think this version provides the "dryness" that most drinkers expect from a gin Martini and yet still gives them a little bit of culinary interest from the vermouth. So while I typically wouldn't recommend serving a 3-to-1 Martini to a random customer who just asks for a (gin) Martini, I think this version would work well for that and begins to provide the customer a little bit of insight as to what they might be typically missing in a Martini
