Glassware
Double Old Fashioned
A rocks glass with room for a full measure of ice and a drink that has been shaken. Anything served on the rocks that started life in a shaker wants this rather than the smaller one.
Capacity
To the brim400 ml
cubed ice displaces175 ml
block ice displaces130 ml
crushed ice displaces220 ml
Solid ice only — the liquid fills the gaps between pieces. The block figure is the same as the smaller glass because a large cube is a large cube; only the room around it changes.
Every drink below was checked against this figure at build time. A recipe that does not fit its stated vessel fails the build rather than shipping.
