Solid ice only, filled to the top as a highball is. 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.
