The rule
When to layer
Layer for visual drama and staged sipping — floats on sours, pousse-cafés, and cream-topped builds.
Skill · Layer slowly over a spoon
Stack liquids by density for bands of flavor and color.

The big idea
Layer by density: heavy and sweet first, lighter liquids floated slowly over a spoon.
Keep these
Density usually tracks sugar — pour heaviest first.
Use the back of a barspoon; fast pours pierce layers.
Wine floats on sours (New York Sour) are the most useful home application.
Serve promptly — diffusion blurs bands as it sits.

Bottom · densest
Syrups and sweet cordials go in first.
Middle
Liqueurs, citrus bases, and sours next.
Top · lightest
High-proof spirits, dry wine, cream — pour over a spoon.
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
Read the drill, then make the drink once focusing on that cue — repetition beats another paragraph.
