When to layer
Layer for visual drama and staged sipping — floats on sours, pousse-cafés, and cream-topped builds.

Technique
Pour liquids slowly in density order so they stack in visible bands instead of mixing.
The big idea
Layering stacks liquids by density — sweet and heavy first, lighter spirits and creams floated slowly over a spoon for bands of flavor and color.
Density usually tracks sugar content; pour heaviest first.
Use the back of a barspoon to spread each layer instead of plunging.
Floats on sours (e.g. red wine on a New York Sour) are the most useful home application.
Patience beats volume — fast pours pierce layers.
Serve promptly; diffusion blurs bands over time.

Heaviest liquid first
Syrups and cordials anchor the bottom.
Spoon on the surface
Pour each lighter layer over an upside-down barspoon.
Lighter liquid last
Spirits and cream float on top when poured slowly.
Pour the densest liquid first. Rest a barspoon on the surface and pour the next liquid slowly over the back of the spoon so it spreads instead of plunging.
In the glass
Open a recipe, focus on this move once, then make it again next week.
