Take a large mixing glass and place ice cubes in it according to your need.
Note: Make sure to use a large mixing glass so the drink does not spill.
Once you add the ice cubes in the glass, pour ½ oz of gin
and ½ oz of dry vermouth into it.
Now, stir the liquors very briefly until they mix well.
Note: Do not make the mistake to shake the mixing glass, as it will water down the drink.
Strain the cocktail into a martini glass that is already chill and top it with a fresh lemon twist.
Garnish the Gibson Cocktail with lemon twist.
Drink or serve the cocktail and enjoy!
