This logo incorporates a swizzle stick (the stick to stir in mixed drinks, from the company name) with an elegant S.
A focus on typography, the S is hand drawn. The spine is doubled, the beak hugs the top of the swizzle stick, and the finial hugs the circle at the bottom of the swizzle stick. The circle on the swizzle stick is the same color as the dot on the eye, connecting the text with the symbol.
The colors are inspired by Spanish Queen Olives, the "gold star" olive used in martinis.
