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
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. Crushed is taken as 7% above cubed: loose crushed ice weighs about 593 to 640 kg per cubic metre against 917 for solid ice, roughly 65% solid, where loose cubes run about 61%.
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.
