Closest to Dry sour. A quarter less sugar. Sharper and more spirit-forward.
Sugar is 22% of the build. In the usual range.
There is no correct ratio - a drier palate genuinely wants less sugar, and how ripe your limes are moves the answer week to week. So this names the template a build is nearest rather than marking it right or wrong, and only warns when a drink sits far enough outside all of them to be a mistake rather than a preference.
The balance chapter covers what moves the ratio, and what to add when a drink tastes wrong.
