How far ahead can you make party drinks? A make-ahead clock for juice, syrup, cream and bubbles

Ingredient	Holds	Where
Spirits, vermouth, bitters	Days to weeks	Sealed; opened vermouth in the fridge
Simple syrup 1:1	About a month	Fridge
Rich syrup 2:1	Several months	Fridge
Lemon or lime juice	Best same day, up to about a day	Fridge, airtight
Cream or egg mix	A few hours is safest	Fridge, never out for long
Bubbles, ice, herbs	Add at serving	In the glass

Rules of thumb that vary by source. Water-based syrups last longer when sealed and chilled, and juice or puree syrups last far less.
